Bulk API integrate using C#

I'm trying to create a Bulk API to send Data to Salesforce .Here is my Code`
string userName = "XXXX";
//Console.Write("Enter password: ");
string password = "XXX";
string SessionId = SalesforceLogin(userName, password);
string JobId = CreateJob(SessionId, "insert", "Contact");
byte[] inputFileData = null;
string jobId = string.Empty;
string resultId = string.Empty;
string batchId = string.Empty;
if (JobId.Length > 0)
{
System.IO.FileInfo oFile = null;
//oFile = New System.IO.FileInfo("data.csv")
oFile = new System.IO.FileInfo(#"D:\request.txt");
System.IO.FileStream oFileStream = oFile.OpenRead();
long lBytes = oFileStream.Length;
int a = (int)lBytes; //modified after conversion
if ((lBytes > 0))
{
byte[] fileData = new byte[lBytes];
// Read the file into a byte array
oFileStream.Read(fileData, 0, a); //modified after conversion
oFileStream.Close();
//Get the file where the Query is present
inputFileData = fileData;
}
batchId= AddBatch(SessionId, JobId, inputFileData);
After that, I create A Job
private static string CreateJob(string sessionId, string sfOperation, string sfObjectName)
{
string str = "";
string reqURL = "";
byte[] bytes;
XmlDocument reqDoc;
XmlDocument respDoc;
str = ""
+ "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\r\n" // added \r\n as recommended by L.B's answer
+ "<jobInfo xmlns=\"http://www.force.com/2009/06/asyncapi/dataload\">"
+ " <operation></operation>" // removed "+sfOperation+"
+ " <object></object>" // removed "+sfObjectName+"
+ " <contentType>XML</contentType>" // should be CSV, NOT XML
+ "</jobInfo>"
;
reqURL = "https://ap2.salesforce.com/services/async/23.0/job";
reqDoc = new XmlDocument();
reqDoc.LoadXml(str);
// added XML modifications
reqDoc.GetElementsByTagName("operation")[0].InnerText = sfOperation;
reqDoc.GetElementsByTagName("object")[0].InnerText = sfObjectName;
bytes = System.Text.Encoding.ASCII.GetBytes(reqDoc.InnerXml);
respDoc = Post(bytes, reqURL, sessionId); // create job
string JobId = (respDoc != null) ?
(respDoc.GetElementsByTagName("id").Count > 0) ?
(respDoc.GetElementsByTagName("id")[0].InnerText) :
"" :
""
;
return JobId;
}`
Then I create A Batch to
private static string AddBatch(string sessionId, string jobId, byte[] fileBytes)
{
string reqURL = "https://ap2.salesforce.com/services/async/23.0/job/" + jobId + "/batch";
XmlDocument respDoc = Post(fileBytes, reqURL, sessionId);
string batchId = (respDoc != null) ?
(respDoc.GetElementsByTagName("id").Count > 0) ?
(respDoc.GetElementsByTagName("id")[0].InnerText) :
"" :
""
;
return batchId;
}
Then the Post Method
private static XmlDocument Post(byte[] bytes, string reqURL, object sfSessionId)
{
WebRequest req = WebRequest.Create(reqURL);
req.Method = "POST";
if ((bytes != null))
{
req.ContentLength = bytes.Length;
}
req.ContentType = "application/xml; charset=UTF-8"; // should be text/csv; when passing a CSV file
req.Headers.Add("X-SFDC-Session: " + sfSessionId);
System.IO.Stream strm = req.GetRequestStream();
if ((bytes != null))
strm.Write(bytes, 0, bytes.Length);
strm.Close();
HttpWebResponse resp = (HttpWebResponse)req.GetResponse();
System.IO.Stream respStrm = resp.GetResponseStream();
XmlDocument respDoc = new XmlDocument();
respDoc.Load(respStrm);
return respDoc;
}
Everything Going Good But when I'm trying to save the Data on Lead it displays the Error
InvalidBatch : Failed to parse XML. Failed to get next element
After Creating Batch I get Result
<?xml version="1.0" encoding="UTF-8"?><batchInfo xmlns="http://www.force.com/2009/06/asyncapi/dataload"><id>7512800000C8OHAAA3</id><jobId>75028000008qk53AAA</jobId><state>Queued</state><createdDate>2017-05-30T14:11:45.000Z</createdDate><systemModstamp>2017-05-30T14:11:45.000Z</systemModstamp><numberRecordsProcessed>0</numberRecordsProcessed><numberRecordsFailed>0</numberRecordsFailed><totalProcessingTime>0</totalProcessingTime><apiActiveProcessingTime>0</apiActiveProcessingTime><apexProcessingTime>0</apexProcessingTime></batchInfo>
One More thing After inserting the Batch, How this job will execute .I'm pasting all the code because it may help Someone if i get the Answer :).

C# - blocking GetRequestStream()

I'm trying to get some data from Aerospike into SOLR, but I'm having a little problem with the web requests to SOLR. I'm using c#-s HttpWebRequest for the web requests on multiple threads. After a few batches the process gets blocked.
I found out that the code stops at the data = request.GetRequestStream(); line, no exceptions, no messages, no timeouts it just waits and does nothing.
Here is a part of my code:
public static ConcurrentBag<String> docs = new ConcurrentBag<String>();
public static int count { get; set; }
<< data extraction into the "docs" container >>
if (count == 50)
{
string dataStr = "{";
string temp;
lock (docs)
{
while (!docs.IsEmpty)
{
docs.TryTake(out temp);
dataStr += temp;
}
}
dataStr = dataStr.ToString().Remove(dataStr.ToString().Length - 1) + "}";
count = 0;
string SOLRInsert = "http://192.168.23.28:8985/solr/test/update";
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(SOLRInsert);
request.ContentType = "application/json";
request.Method = "POST";
byte[] dataBytes = Encoding.ASCII.GetBytes(dataStr);
request.ContentLength = dataBytes.Length;
request.Proxy = null;
Stream data = null;
try
{
data = request.GetRequestStream();
sw.Start();
data.Write(dataBytes, 0, dataBytes.Length);
sw.Stop();
//data.Close();
data.Dispose();
}
catch (Exception ex)
{
Console.Write(key.userKey.ToString() + "->" + ex.ToString() + "\r\n");
File.AppendAllText(#"import.log", key.userKey.ToString() + "->" + ex.ToString() + Environment.NewLine);
}
finally
{
if (data != null)
{
//data.Close();
data.Dispose();
}
}
}
Any help would be appreciated.

Facebook active token failure C# HttpWebRequest

I obtain an access_token OK from Facebook, but whenever I try to use it, it fails (bad request).
It looks like the access_token is not being sent to the server correctly. I have used Server.UrlEncode to encode it.
Any ideas what I am doing wrong?
string ourAccessToken = "unknown";
//--------------------------------------
protected void Page_Load(object sender, EventArgs e)
{
getAccessToken();
getMe();
}
// -----------------------
private void getAccessToken()
{
string result = "unknown";
try
{
// get app access token
string thisURL = "https://graph.facebook.com/oauth/access_token";
thisURL += "?client_id=" + ourClientID;
thisURL += "&client_secret=" + ourClientSecret;
thisURL += "&grant_type=client_credentials";
thisURL += "&redirect_uri=" + Server.UrlEncode(ourSiteRedirectURL);
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create( thisURL);
request.Method = "GET";
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
HttpStatusCode rc = response.StatusCode;
if( rc == HttpStatusCode.OK)
{
StreamReader Sreader = new StreamReader( response.GetResponseStream());
result = Sreader.ReadToEnd();
Sreader.Close();
}
response.Close();
}
catch (Exception exc)
{
result = "ERROR : " + exc.ToString();
}
Response.Write( "<br>result=[" + result + "]");
// extract accessToken
string accessToken = "";
int equalsAt = result.IndexOf( "=");
if( equalsAt >= 0 && result.Length > equalsAt) accessToken = (result.Substring( equalsAt + 1)).Trim();
Response.Write( "<br>accessToken=[" + accessToken + "]");
ourAccessToken = accessToken;
}
// -----------------------
private void getMe()
{
string result = "unknown";
try
{
string thisURL = "https://graph.facebook.com/me?access_token=" + Server.UrlEncode(ourAccessToken);
Response.Write("<br>thisURL=" + thisURL);
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create( thisURL);
request.Method = "GET";
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
HttpStatusCode rc = response.StatusCode;
if( rc == HttpStatusCode.OK)
{
StreamReader Sreader = new StreamReader( response.GetResponseStream());
result = Sreader.ReadToEnd();
Sreader.Close();
}
response.Close();
}
catch (Exception ex)
{
Response.Write("<br>getMe Exc: " + ex.Message.ToString() + "<br>");
}
Response.Write("<br>getMe result = " + result + "<br><br>");
}
Thanks

Right settings in App-Dashboard? If you active "Native/Desktop" you can not send API-Calls with this method, see:
https://developers.facebook.com/docs/facebook-login/access-tokens?locale=en_US#apptokens

After a lot of trial and error, I conclude that an App Access Token is not relevant, and that the ClientID and ClientSecret should be used directly. I want my App to generate a set of photographs of registered users. Because the server is making the call, there is no meaning to "me". A set of data can be obtained by preparing a batch process:
string p1 = "access_token=" + Server.UrlEncode(ourClientID + "|" + ourClientSecret);
string p2 = "&batch=" +
Server.UrlEncode( " [ { \"method\": \"get\", \"relative_url\": \"" + chrisFBID + "?fields=name,picture.type(square)\" }, " +
" { \"method\": \"get\", \"relative_url\": \"" + johnFBID + "?fields=name,picture.type(large)\" }, " +
" { \"method\": \"get\", \"relative_url\": \"" + stephFBID + "?fields=name,picture.type(large)\" } ]");
string responseData = "";
try
{
HttpWebRequest httpRequest = (HttpWebRequest)WebRequest.Create("https://graph.facebook.com/");
httpRequest.Method = "POST";
httpRequest.ContentType = "application/x-www-form-urlencoded";
byte[] bytedata = Encoding.UTF8.GetBytes(p1 + p2);
httpRequest.ContentLength = bytedata.Length;
Stream requestStream = httpRequest.GetRequestStream();
requestStream.Write(bytedata, 0, bytedata.Length);
requestStream.Close();
HttpWebResponse httpWebResponse = (HttpWebResponse)httpRequest.GetResponse();
Stream responseStream = httpWebResponse.GetResponseStream();
StreamReader reader = new StreamReader(responseStream, System.Text.Encoding.UTF8);
responseData = reader.ReadToEnd();
}
catch (Exception ex)
{
Response.Write(ex.Message.ToString() + "<br>");
}
Response.Write("<br>" + responseData + "<br><br>");
I also conclude that the FB documentation suffers from the usual fatal flaw of documentation: it has been written by an expert and never tested on a novice user before release.

getting 403 error in release version and work fine in debug version

I working in project that connect to appannie.com API and get result and it is working fine in debug but when I publish it and try to test it I get this page :

Once you publish it, one of the following is not taking effect:
Credentials
Proxy Settings.
Hence the remote api is giving back a 403. 2 ways to torubleshoot this further:
Run fiddler trace on the working request/response and compare it with the non-working request/response. Typically a good API has more details in the response body as to why it is a 403 error.. (token invalid, invalid credentials etc.)
You can also catch a WebException in code, and try to get the exception body if any. The same will also be visible in Fiddler.
<< code formatting refuses to work on my browser. please bear with unformatted code below >>
try
{
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
}
catch (WebException ex)
{
// breakpoint and see what this is.
string errorDetails = new StreamReader(ex.Response.GetResponseStream()).ReadToEnd();
}

WebDAV Exchange 2003 failing when specifying a date

I am using the following code to retrieve emails from an Exchange 2003 server. All was working on Friday and now it fails.
From some investigation I have narrowed it to the targetDate variable. Seems if the date is in April it fails with a 400 back from the server. I have commented this line out and tried various dates 2012-3-29, 2012-4-1, 2012-4-10 (today) and the ones in April seem to fail.
Some kind of sick April fools joke?
The code itself is derived from this article: http://www.codeproject.com/Articles/42458/Using-Exchange-2003-with-Webdav-Send-Retrieve-Atta
public XmlDocument GetMailAll()
{
HttpWebRequest request = default(HttpWebRequest);
HttpWebResponse response = default(HttpWebResponse);
string rootUri = null;
string query = null;
byte[] bytes = null;
Stream requestStream = default(Stream);
Stream responseStream = default(Stream);
XmlDocument xmlDoc = default(XmlDocument);
xmlDoc = new XmlDocument();
try
{
DateTime targetDateTime = DateTime.Today.AddDays(-5);
String targetDate = ""+targetDateTime.Year + "-" + targetDateTime.Month + "-" + targetDateTime.Day;
rootUri = server + "/Exchange/" + alias + "/" + inbox;
query = "<?xml version=\"1.0\"?>"
+ "<D:searchrequest xmlns:D = \"DAV:\" xmlns:m=\"urn:schemas:httpmail:\">"
+ "<D:sql>SELECT \"urn:schemas:httpmail:hasattachment\", \"DAV:displayname\", "
+ "\"urn:schemas:httpmail:from\", \"urn:schemas:httpmail:subject\", "
//+ "\"urn:schemas:httpmail:htmldescription\"," //Return full body (not necessary right now)
+ "\"urn:schemas:httpmail:datereceived\", \"urn:schemas:httpmail:read\" FROM \"" + rootUri
+ "\" WHERE \"DAV:ishidden\" = false "
+ "AND \"DAV:isfolder\" = false "
//+ "AND \"urn:schemas:httpmail:read\" = false"
+ "AND \"urn:schemas:httpmail:datereceived\" >= CAST(\"" + targetDate + "T00:00:000Z\" AS 'dateTime.tz')"
+ "</D:sql></D:searchrequest>";
request = (HttpWebRequest)WebRequest.Create(rootUri);
request.Timeout = 5000;
request.Credentials = new NetworkCredential(alias, password, domain);
request.Method = "SEARCH";
request.ContentType = "text/xml";
request.Headers.Add("Translate", "F");
bytes = System.Text.Encoding.UTF8.GetBytes(query);
request.ContentLength = bytes.Length;
requestStream = request.GetRequestStream();
requestStream.Write(bytes, 0, bytes.Length);
requestStream.Close();
response = (HttpWebResponse)request.GetResponse();
authCookies = new List<Cookie>();
foreach(Cookie cookie in response.Cookies)
{
authCookies.Add(cookie);
}
responseStream = response.GetResponseStream();
xmlDoc.Load(responseStream);
responseStream.Close();
}
catch (WebException ex)
{
if (ex.Response == null)
{
throw new Exception();
}
else if ((ex.Response as HttpWebResponse).StatusCode == HttpStatusCode.Unauthorized)
{
throw new ExchangeCatastrophicException();
}
else
{
throw new ExchangeFailedException();
}
}
catch (Exception ex)
{
throw;
}
return xmlDoc;
}

Finally got it working. The exact targetDate to cast including the T00:00:..Z part must match the specification on http://msdn.microsoft.com/en-us/library/aa123600%28v=exchg.65%29.aspx
I now have:
DateTime targetDateTime = DateTime.Today;
string targetDate = targetDateTime.ToString("yyyy-MM-dd");
snip
+ "AND \"urn:schemas:httpmail:datereceived\" >= CAST(\"" + targetDate + "T00:00:00Z" + "\" AS 'dateTime.tz')"
Note that the seconds part is two zero's instead of three.
