I have to use above code to consume service, but i am getting different errors-
1) You must provide a request body if you set ContentLength>0 ....
What is the code I am missing exactly here.
You missing few lines of code. You only setting ContentLength but you do not write content.
req.ContentLength = data.Length;
//Write request data(setting content of request)
Stream reqStream = req.GetRequestStream();
reqStream.Write(data, 0, data.Length);
reqStream.Close();
res = (HttpWebResponse)req.GetResponse();

i received an Error when i am posting a XML file via HttpWebRequest. I would like to show the response as an label.
My Code:
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https:xxxxxxxxxxxx");
byte[] bytes;
var file = Environment.SpecialFolder.MyDocuments + "\\myRequest.xml";
bytes = System.Text.Encoding.ASCII.GetBytes(file);
request.Headers.ToString();
request.ContentType = "application/xml; encoding='utf-8'";
request.ContentLength = bytes.Length;
request.Method = "POST";
Stream requestStream = request.GetRequestStream();
requestStream.Write(bytes, 0, bytes.Length);
requestStream.Close();
HttpWebResponse response;
response = (HttpWebResponse)request.GetResponse();
if (response.StatusCode == HttpStatusCode.OK)
{
Stream responseStream = response.GetResponseStream();
string responseStr = new StreamReader(responseStream).ReadToEnd();
label13.Text = responseStr;
}
My Response in label13.Text = The supplied data could not be imported in the stated format -[XML2Array] Error parsing the XML String
I'm try to Send Data Using the WebRequest with POST But my problem is No data has be streamed to the server.
string user = textBox1.Text;
string password = textBox2.Text;
ASCIIEncoding encoding = new ASCIIEncoding();
string postData = "username" + user + "&password" + password;
byte[] data = encoding.GetBytes(postData);
WebRequest request = WebRequest.Create("http://localhost/s/test3.php");
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = data.Length;
Stream stream = request.GetRequestStream();
stream.Write(data, 0, data.Length);
stream.Close();
WebResponse response = request.GetResponse();
stream = response.GetResponseStream();
StreamReader sr99 = new StreamReader(stream);
MessageBox.Show(sr99.ReadToEnd());
sr99.Close();
stream.Close();
here the result
It's because you need to assign your posted parameters with the = equal sign:
byte[] data = Encoding.ASCII.GetBytes(
$"username={user}&password={password}");
WebRequest request = WebRequest.Create("http://localhost/s/test3.php");
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = data.Length;
using (Stream stream = request.GetRequestStream())
{
stream.Write(data, 0, data.Length);
}
string responseContent = null;
using (WebResponse response = request.GetResponse())
{
using (Stream stream = response.GetResponseStream())
{
using (StreamReader sr99 = new StreamReader(stream))
{
responseContent = sr99.ReadToEnd();
}
}
}
MessageBox.Show(responseContent);
See the username= and &password= in post data formatting.
You can test it on this fiddle.
Edit :
It seems that your PHP script has parameters named diffently than those used in your question.
Trying to call WebService using HTTPWebRequest and posting data, it results in invalid request format, I have added http verbs post in both client and webservice, any ideas here ?
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create("http://localhost/WS/test.asmx/GetData");
String xmlString = "Montreal";
ASCIIEncoding encoding = new ASCIIEncoding();
byte[] bytesToWrite = encoding.GetBytes(xmlString);
request.Method = "POST";
request.ContentLength = bytesToWrite.Length;
request.ContentType = "text/xml;charset=UTF-8";
Stream newStream = request.GetRequestStream();
newStream.Write(bytesToWrite, 0, bytesToWrite.Length);
newStream.Close(); //fails here with error message Request format is invalid: text/xml;charset=UTF-8.
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Stream dataStream = response.GetResponseStream();
StreamReader reader = new StreamReader(dataStream);
string responseFromServer = reader.ReadToEnd();
Console.WriteLine(responseFromServer);
I got to modify the approach, this worked for me.
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create("http://localhost/WS/test.asmx");
String xmlData = "Montréal";
String xmlString = "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:tem=\"http://tempuri.org/\"><soapenv:Header/> <soapenv:Body><tem:GetData><tem:data>" + xmlData + "</tem:data></tem:GetData></soapenv:Body></soapenv:Envelope>";
byte[] bytesToWrite = Encoding.UTF8.GetBytes(xmlString);
request.Method = "POST";
request.ContentLength = bytesToWrite.Length;
request.ContentType = "text/xml;charset=UTF-8;";
Stream newStream = request.GetRequestStream();
newStream.Write(bytesToWrite, 0, bytesToWrite.Length);
newStream.Close();
try
{
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Stream dataStream = response.GetResponseStream();
StreamReader reader = new StreamReader(dataStream);
string responseFromServer = reader.ReadToEnd();
Console.WriteLine(responseFromServer);
}
catch (Exception ex)
{
string msg = ex.Message;
}
Box.com's Enterprise User Provisioning API requires OAUTH2 token in the header of the request ("Authorization: Bearer faKE_toKEN_1234"). I've ran the code below against http://www.xhaus.com/headers, http://httpbin.org/post and http://www.cs.tut.fi/cgi-bin/run/~jkorpela/echo.cgi and observed packets with Microsoft Network Monitor and as far as I know my request header does not include the "Authorization" value I wish to include there.
Is the code below missing something (code or a point)?
HttpWebRequest request = (HttpWebRequest) WebRequest.Create(API_URL);
request.Method = "POST";
request.ServicePoint.Expect100Continue = false;
request.ContentType = "application/x-www-form-urlencoded";
request.Timeout=10000;
string postData = Parameters;
ASCIIEncoding encoding = new ASCIIEncoding ();
byte[] byte1 = encoding.GetBytes (postData);
request.ContentLength = byte1.Length;
Stream reqStream = request.GetRequestStream();
reqStream.Write(byte1, 0, byte1.Length);
reqStream.Close();
//This is puzzling me, why can't I see this header anywere
//when debugging with packet monitor etc?
request.Headers.Add("Authorization: Bearer " + access_token);
HttpWebResponse response = (HttpWebResponse) request.GetResponse();
Stream dataStream = response.GetResponseStream ();
StreamReader reader = new StreamReader (dataStream);
string txtResponse = reader.ReadToEnd ();
return txtResponse;
I think you need to set the header before you write the postData and close the request stream. This appeared to work for me:
static void Main(string[] args)
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://www.xhaus.com/headers");
request.Method = "POST";
request.ServicePoint.Expect100Continue = false;
request.ContentType = "application/x-www-form-urlencoded";
request.Timeout = 10000;
request.Headers.Add("Authorization: Bearer_faKE_toKEN_1234");
string postData = "postData";
ASCIIEncoding encoding = new ASCIIEncoding();
byte[] byte1 = encoding.GetBytes(postData);
request.ContentLength = byte1.Length;
Stream reqStream = request.GetRequestStream();
reqStream.Write(byte1, 0, byte1.Length);
reqStream.Close();
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Stream dataStream = response.GetResponseStream();
StreamReader reader = new StreamReader(dataStream);
string txtResponse = reader.ReadToEnd();
Console.WriteLine(txtResponse);
Console.ReadKey();
}
I want to send string from my C# app to my PHP page and I tried some different solutions that i found in the internet. One of them is this:
C# code:
string url = "http://localhost:8080/test.php";
string str = "test";
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
req.Method = "POST";
string Data = "message=" + str;
byte[] postBytes = Encoding.ASCII.GetBytes(Data);
req.ContentType = "application/x-www-form-urlencoded";
req.ContentLength = postBytes.Length;
Stream requestStream = req.GetRequestStream();
requestStream.Write(postBytes, 0, postBytes.Length);
requestStream.Close();
HttpWebResponse response = (HttpWebResponse)req.GetResponse();
Stream resStream = response.GetResponseStream();
var sr = new StreamReader(response.GetResponseStream());
string responseText = sr.ReadToEnd();
and PHP code:
foreach($_POST as $pdata)
echo $pdata;
But it's just a blank page. I dont know what the problem is.
I haven't used c# in a long time, but this should be the solution:
string url = "http://localhost:8080/test.php";
string str = "test";
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
req.Method = "POST";
string Data = "message=" + str;
UTF8Encoding utf8 = new UTF8Encoding();
byte[] postBytes = utf8.GetBytes(Data);
req.ContentType = "application/x-www-form-urlencoded";
req.ContentLength = postBytes.Length;
Stream requestStream = req.GetRequestStream();
requestStream.Write(postBytes, 0, postBytes.Length);
requestStream.Close();
HttpWebResponse response = (HttpWebResponse)req.GetResponse();
Stream resStream = response.GetResponseStream();
var sr = new StreamReader(resStream);
string responseText = sr.ReadToEnd();
What I did was change the encoding from ASCII to UTF8. UTF8 is what application/x-www-form-urlencoded expects.
As for your php, I assume you have opening and closing brackets on your foreach method.
Edit:
Okay, well I noticed an error in your c#. You were getting the response stream twice. That might have caused some error, but here is how I would structure my php:
<?php
foreach($_POST as $key => $value){
echo $value . "<br>";
}
?>
