Here Upload pdf via multipart-HTML-Post does change file I created some code for uploading a pdf with a multipart-HTML-Post in vba.
This is the code I use:
Public Function sap_addTest(ByVal par_objectID As String, ByVal par_description As String, ByVal par_filename As String) As Integer
Dim ls_param As String
Dim text As String
Dim line As String
Dim url As String
Dim web As MSXML2.XMLHTTP60
url = "http://someurl.xml"
Set web = CreateObject("MSXML2.XMLHTTP")
Call web.Open("POST", url, False)
Const Boundary As String = "AaB03x"
Call web.setRequestHeader("content-type", "multipart/form-data;boundary=" & Boundary)
Call web.setRequestHeader("ws-callingapplication", sys_db)
Call web.setRequestHeader("Connection", "Keep-Alive")
Call web.setRequestHeader("cache-control", "no-cache")
Dim baBuffer() As Byte
Dim bytData
Dim bytPayLoad
With CreateObject("ADODB.Stream")
.Type = 1
.Mode = 3
.Open
.LoadFromFile par_filename
bytData = .Read
End With
With CreateObject("ADODB.Stream")
.Mode = 3
.Charset = "Windows-1252"
.Open
.Type = 2
.WriteText vbNewLine & "--" & Boundary & vbNewLine & "Content-Disposition: form-data; name=""object_id""" & vbNewLine & vbNewLine & par_objectID
.WriteText vbNewLine & "--" & Boundary & vbNewLine & "Content-Disposition: form-data; name=""description""" & vbNewLine & vbNewLine & par_description
.WriteText vbNewLine & "--" & Boundary & vbNewLine & "Content-Disposition: form-data; name=""file""; filename=""" & par_filename & """" & vbNewLine
.WriteText vbNewLine
.Position = 0
.Type = 1
.Position = .Size
.Write bytData
.Position = 0
.Type = 2
.Position = .Size
.WriteText vbNewLine & vbNewLine & "--" & Boundary & "--" & vbNewLine
.Position = 0
.Type = 1
bytPayLoad = .Read
End With
Call web.Send(bytPayLoad)
'Debug.Print web.status
'Debug.Print web.responseText
End Function
But now I have to do the same thing in C#. I probably use HttpWebRequest instead of XMLHTTP. But my problem is how to replace the ADODB.Stream? System.IO.Stream does not seem to have the functions/properties I use (Mode, Type, WriteText, charset). This is the code I use right now:
public void Upload(ICommandLineInfo info)
{
var webRequest = HttpWebRequest.Create(info.Url) as HttpWebRequest;
const string HTTPBoundary = "AaB03x";
webRequest.ContentType = "multipart/form-data;boundary=" + HTTPBoundary;
const string HTTPHeaderCallingApplicationName = "ws-callingapplication";
webRequest.Headers.Add(HTTPHeaderCallingApplicationName, info.CallingApplication);
webRequest.KeepAlive = true;
const string HTTPHeaderCacheControlName = "cache-control";
const string HTTPHeaderValueCacheControlNo = "no-cache";
webRequest.Headers.Add(HTTPHeaderCacheControlName, HTTPHeaderValueCacheControlNo);
webRequest.Method = "POST";
using (Stream requestStream = webRequest.GetRequestStream())
{
//Here I dont know how to write my file into the Request stream
//requestStream.Write(bytes, 0, bytes.Length); ?
requestStream.Close();
}
var response = (HttpWebResponse)webRequest.GetResponse();
}
I found this multipart post -- uploading a file to, but the code is Java and there are several pieces missing in C# (like HttpPost, MultipartEntityBuilder and so on)
So how to build the byte array for the request stream?
Update:
This is the code I use currently:
public void Upload(ICommandLineInfo info)
{
var webRequest = HttpWebRequest.Create(info.Url) as HttpWebRequest;
const string HTTPBoundary = "AaB03x";
webRequest.ContentType = "multipart/form-data;boundary=" + HTTPBoundary;
const string HTTPHeaderCallingApplicationName = "ws-callingapplication";
webRequest.Headers.Add(HTTPHeaderCallingApplicationName, info.CallingApplication);
webRequest.KeepAlive = true;
webRequest.UseDefaultCredentials = true;
webRequest.PreAuthenticate = true;
webRequest.Credentials = CredentialCache.DefaultCredentials;
const string HTTPHeaderCacheControlName = "cache-control";
const string HTTPHeaderValueCacheControlNo = "no-cache";
webRequest.Headers.Add(HTTPHeaderCacheControlName, HTTPHeaderValueCacheControlNo);
webRequest.Method = "POST";
Stream requestStream = webRequest.GetRequestStream();
string stringInfo = "";
stringInfo = stringInfo + Environment.NewLine + "--" + HTTPBoundary + Environment.NewLine + "Content-Disposition: form-data; name=\"itemName\"" + Environment.NewLine + Path.GetFileName(info.Filename);
stringInfo = stringInfo + Environment.NewLine + "--" + HTTPBoundary + Environment.NewLine + "Content-Disposition: form-data; name=\"parentNickname\"" + Environment.NewLine + info.ParentNickname;
stringInfo = stringInfo + Environment.NewLine + "--" + HTTPBoundary + Environment.NewLine + "Content-Disposition: form-data; name=\"file\"; filename=\"" + info.Filename + "\"" + Environment.NewLine + Environment.NewLine;
var stringBytes = Encoding.ASCII.GetBytes(stringInfo);
requestStream.Write(stringBytes, 0, stringBytes.Length);
var fileBytes = File.ReadAllBytes(info.Filename);
requestStream.Write(stringBytes, 0, stringBytes.Length);
string endInfo = Environment.NewLine+ Environment.NewLine + "--" + HTTPBoundary + "--" + Environment.NewLine;
var endBytes = Encoding.ASCII.GetBytes(endInfo);
requestStream.Write(endBytes, 0, endBytes.Length);
requestStream.Flush();
requestStream.Close();
var response = (HttpWebResponse)webRequest.GetResponse();
}
unfortunately webRequest.GetResponse() throws an exception:
The remoteserver returned an error. 500: Internal server error
My college - who is responsible for the serverpart - tells me that he gets an "unexpected end of stream"-error.
It seems like there is a ADODB Stream in c# also. In the Reference: "ADODB". So my final Code lookes like this:
public void Upload(ICommandLineInfo info)
{
var webRequest = HttpWebRequest.Create(info.Url) as HttpWebRequest;
const string HTTPBoundary = "AaB03x";
webRequest.ContentType = "multipart/form-data;boundary=" + HTTPBoundary;
const string HTTPHeaderCallingApplicationName = "ws-callingapplication";
webRequest.Headers.Add(HTTPHeaderCallingApplicationName, info.CallingApplication);
webRequest.KeepAlive = true;
webRequest.UseDefaultCredentials = true;
webRequest.PreAuthenticate = true;
webRequest.Credentials = CredentialCache.DefaultCredentials;
const string HTTPHeaderCacheControlName = "cache-control";
const string HTTPHeaderValueCacheControlNo = "no-cache";
webRequest.Headers.Add(HTTPHeaderCacheControlName, HTTPHeaderValueCacheControlNo);
webRequest.Method = "POST";
ADODB.Stream fileStream = new ADODB.Stream();
fileStream.Type = ADODB.StreamTypeEnum.adTypeBinary;
fileStream.Mode = ADODB.ConnectModeEnum.adModeReadWrite;
fileStream.Open();
fileStream.LoadFromFile(info.Filename);
var byteData = fileStream.Read();
fileStream.Close();
ADODB.Stream mixedStream = new ADODB.Stream();
mixedStream.Mode = ADODB.ConnectModeEnum.adModeReadWrite;
mixedStream.Charset = "utf-8";
mixedStream.Open();
mixedStream.Type = ADODB.StreamTypeEnum.adTypeText;
mixedStream.WriteText(Environment.NewLine + "--" + HTTPBoundary + Environment.NewLine + "Content-Disposition: form-data; name=\"itemName\"" + Environment.NewLine + Environment.NewLine + Path.GetFileName(info.Filename));
mixedStream.WriteText(Environment.NewLine + "--" + HTTPBoundary + Environment.NewLine + "Content-Disposition: form-data; name=\"parentNickname\"" + Environment.NewLine + Environment.NewLine + info.ParentNickname);
mixedStream.WriteText(Environment.NewLine + "--" + HTTPBoundary + Environment.NewLine + "Content-Disposition: form-data; name=\"file\"; filename=\"" + info.Filename + "\"" + Environment.NewLine);
mixedStream.WriteText(Environment.NewLine);
mixedStream.Position = 0;
mixedStream.Type = ADODB.StreamTypeEnum.adTypeBinary;
mixedStream.Position = mixedStream.Size;
mixedStream.Write(byteData);
byteData = null;
mixedStream.Position = 0;
mixedStream.Type = ADODB.StreamTypeEnum.adTypeText;
mixedStream.Position = mixedStream.Size;
mixedStream.WriteText(Environment.NewLine + Environment.NewLine + "--" + HTTPBoundary + "--" + Environment.NewLine);
mixedStream.Position = 0;
mixedStream.Type = ADODB.StreamTypeEnum.adTypeBinary;
var read = mixedStream.Read();
webRequest.ContentLength = read.Length;
Stream requestStream = webRequest.GetRequestStream();
requestStream.Write(read, 0, read.Length);
requestStream.Close();
try
{
var response = (HttpWebResponse)webRequest.GetResponse();
}
catch (WebException exception)
{
using (var reader = new System.IO.StreamReader(exception.Response.GetResponseStream()))
{
string responseText = reader.ReadToEnd();
}
}
}
This seems to be not the perfect way to do this in C# but it works.

Your App must be whitelisted by Twitter in order to get email from:
https://api.twitter.com/1.1/account/verify_credentials.json
So if you remove ?include_email=true part of the request url you will get a response with some fields and then you can get the screen_name of the user for example.
You can ask to be whitelisted using the form bellow (check > "I need access to special permissions"):
https://support.twitter.com/forms/platform
In my case they granted me access after some few hours...

I have a c# function that is used to upload a file to a PHP web service. The PHP web service is expecting the following
A POST parameter called UploadFileRequestDto containing some XML data
The File stream
For some odd reason the $_POST parameter contains the UploadFileRequestDto only some of the time. If I look at the contents of
file_get_contents("php://input"))
I can see that the request is comming through as expected with the UploadFileRequestDto included.
Doing a
print_r($_REQUEST)
is returning an empty array.
Can anyone help me with a solution to this problem, my C# function is stipulated below
public string UploadFile(UploadFileRequestDto uploadFileRequestDto,string fileToUpload, string fileUploadEndpoint)

Ok I found the problem, the
post_max_size
setting in the php.ini was set to 8M and some of the files I was trying to upload exeeded 8M. Changed this setting to 16M and restarted the PHP service.
When the file size exeeds the limit that was set the $_POST global is empty.
I am trying to use the ImageShack API to upload images. To use it, I am supposed to POST the image using multipart/form-data. I did it like ...
var postData = "";
var req = HttpWebRequest.Create("http://www.imageshack.us/upload_api.php");
req.Method = "POST";
req.ContentType = "multipart/form-data";
postData += "key=my_key_here&";
postData += "type=base64&";
// get base64 data from image
byte[] bytes = File.ReadAllBytes(#"D:\tmp\WpfApplication1\WpfApplication1\Images\Icon128.gif");
string encoded = Convert.ToBase64String(bytes);
postData += "fileupload=" + encoded;
byte[] reqData = Encoding.UTF8.GetBytes(postData);
using (Stream dataStream = req.GetRequestStream())
{
dataStream.Write(reqData, 0, reqData.Length);
}
var res = (HttpWebResponse)req.GetResponse();
var resStream = res.GetResponseStream();
var reader = new StreamReader(resStream);
string resString = reader.ReadToEnd();
txt1.Text = resString;
but ImageShack is complaining that
<links>
<error id="parameter_missing">Sorry, but we've detected that unexpected data is received. Required parameter 'fileupload' is missing or your post is not multipart/form-data</error>
</links>
FileUpload is present and I am using multipart/form-data whats wrong?
UPDATE:
New Code http://pastebin.com/TN6e0CD8
Post data http://pastebin.com/fYE9fsxs
UPDATE 2
i looked at the other question Multipart forms from C# client. modified my code with boundary, removed the expect 100 header still i cant get it working ...
ServicePointManager.Expect100Continue = false;
var boundary = "-----------------------------28520690214962";
var newLine = Environment.NewLine;
var propFormat = boundary + newLine +
"Content-Disposition: form-data; name=\"{0}\"" + newLine + newLine +
"{1}" + newLine + newLine;
var fileHeaderFormat = boundary + newLine +
"Content-Disposition: form-data; name=\"{0}\"; filename=\"{1}\"" + newLine;
var req = (HttpWebRequest)HttpWebRequest.Create("http://jm/php/upload.php");
req.Method = WebRequestMethods.Http.Post;
req.ContentType = "multipart/form-data; boundary=" + boundary;
using (var reqStream = req.GetRequestStream()) {
var reqWriter = new StreamWriter(reqStream);
var tmp = string.Format(propFormat, "str1", "hello world");
reqWriter.Write(tmp);
tmp = string.Format(propFormat, "str2", "hello world 2");
reqWriter.Write(tmp);
reqWriter.Write(boundary + "--");
reqWriter.Flush();
}
var res = req.GetResponse();
using (var resStream = res.GetResponseStream()) {
var reader = new StreamReader(resStream);
txt1.Text = reader.ReadToEnd();
}
I finally got it with the following code ...
var boundary = "------------------------" + DateTime.Now.Ticks;
var newLine = Environment.NewLine;
var propFormat = "--" + boundary + newLine +
"Content-Disposition: form-data; name=\"{0}\"" + newLine + newLine +
"{1}" + newLine;
var fileHeaderFormat = "--" + boundary + newLine +
"Content-Disposition: form-data; name=\"{0}\"; filename=\"{1}\"" + newLine;
var req = (HttpWebRequest)HttpWebRequest.Create("http://jm/php/upload.php");
req.Method = WebRequestMethods.Http.Post;
req.ContentType = "multipart/form-data; boundary=" + boundary;
using (var reqStream = req.GetRequestStream()) {
var reqWriter = new StreamWriter(reqStream);
var tmp = string.Format(propFormat, "str1", "hello world");
reqWriter.Write(tmp);
tmp = string.Format(propFormat, "str2", "hello world 2");
reqWriter.Write(tmp);
reqWriter.Write("--" + boundary + "--");
reqWriter.Flush();
}
var res = req.GetResponse();
using (var resStream = res.GetResponseStream()) {
var reader = new StreamReader(resStream);
txt1.Text = reader.ReadToEnd();
}
Notice boundaries have to begin with -- {boundary declared in ContentType} and ending boundary must begin & end with -- . in my case, I originally used
var propFormat = boundary + newLine +
"Content-Disposition: form-data; name=\"{0}\"" + newLine + newLine +
"{1}" + newLine;
replace it with
var propFormat = "--" + boundary + newLine +
"Content-Disposition: form-data; name=\"{0}\"" + newLine + newLine +
"{1}" + newLine;
and everything works
I believe that you are not building the request body correctly.
First, you need to include part boundary (random text) in content type header. For example,
Content-Type: multipart/form-data;
boundary=----WebKitFormBoundarySkAQdHysJKel8YBM
Now format of request body will be something like
------WebKitFormBoundarySkAQdHysJKel8YBM
Content-Disposition: form-data;name="key"
KeyValueGoesHere
------WebKitFormBoundarySkAQdHysJKel8YBM
Content-Disposition: form-data;name="param2"
ValueHere
------WebKitFormBoundarySkAQdHysJKel8YBM
Content-Disposition: form-data;name="fileUpload"; filename="y1.jpg"
Content-Type: image/jpeg
[image data goes here]
I will suggest you to use tool such as Fiddler to understand how these requests are built.
This is nothing like multipart/form-data
There's no boundaries between fields (needed even with one field).
Why are you base-64 encoding?
There's no indication of the content-type of the image.
Take a look at RFC 2388 for the actual format spec. It can also be useful to look at a Fiddler grab of a file upload from a web-page.
