Cannot upload a file in blob in sharefile - salesforce

I am trying to upload a file in Citrix ShareFile via REST API. There are four requests
Get the access_token
Get the folder URI's to decide n which I am going to upload the file.
Get chunk Uri
Upload the file in that chunk Uri
The first three steps work perfectly. When I am trying to POST a request for the no 4. part,
it is creating a file in sharefile but with size of 0.
I have tried that with POSTMAN, and with form-data and the selection of a file, it is working fine. The file is uploaded in sharefile.
The problem arises when I am trying to upload blob data.
I am calling this methods from Salesforce Platform and in Salesforce, I cannot get the physical file in a physical location. I have blob file data stored in salesforce database.
The below part works well.
String fileName_m = 'a12.pdf';
// Get Authentication Token
HttpRequest req = new HttpRequest();
req.setEndpoint('https://{server}.sf-api.com/oauth/token?grant_type=password&client_id={client_id}&client_secret={secret}&username={user_name}&password={password}!');
req.setMethod('GET');
Http http = new Http();
HttpResponse response = http.send(req);
System.Debug(response.getBody());
Map<String, Object> results = (Map<String, Object>)JSON.deserializeUntyped(response.getBody());
String token = '';
String refreshtoken = '';
if(response.getStatusCode() == 200){
token = (String)results.get('access_token');
refreshtoken = (String)results.get('refresh_token');
}
system.debug('token=' + token);
// Get Folder ID
HttpRequest req1 = new HttpRequest();
req1.setEndpoint('https://{server}.sf-api.com/sf/v3/Items?$expand=Children');
req1.setMethod('GET');
req1.setHeader('Authorization','Bearer ' + token);
Http http1 = new Http();
HttpResponse response1 = http1.send(req1);
System.Debug(response1.getBody());
Map<String, Object> results1 = (Map<String, Object>)JSON.deserializeUntyped(response1.getBody());
String url = '';
if(response1.getStatusCode() == 200){
url = (String)results1.get('url');
}
System.Debug('Folder Url ' + url);
// Get Chunk URI
HttpRequest req2 = new HttpRequest();
String endPoint = url + '/Upload2';
req2.setEndpoint(endPoint);
req2.setMethod('POST');
req2.setHeader('Authorization','Bearer ' + token);
req2.setHeader('Content-Type', 'application/x-www-form-urlencoded');
String payload1 = 'FileName='+fileName_m;
req2.setBody(payload1);
Http http2 = new Http();
HttpResponse response2 = http2.send(req2);
Map<String, Object> results2 = (Map<String, Object>)JSON.deserializeUntyped(response2.getBody());
String ChunkUri = '';
if(response2.getStatusCode() == 200){
ChunkUri = (String)results2.get('ChunkUri');
}
System.Debug('ChunkUri' + ChunkUri);
But, when I am trying to upload blob file data in sharefile, the API responds with a 200 status code. In sharefile, the file is created, but the size of the file is 0.
// Problem is here, it is not working
// Upload File
Attachment att = [SELECT Id, Body, Name, ContentType FROM Attachment WHERE Id='00P3p00001XNLOHEA5'];
String body = EncodingUtil.base64Encode(att.body);
List<Attachment> cvList = [SELECT Id, Body, Name, ContentType FROM Attachment WHERE Id='00P3p00001XNLOHEA5'];
String attachmentBody = EncodingUtil.base64Encode(cvList[0].Body);
Blob pdfBlob = EncodingUtil.base64Decode(attachmentBody);
system.debug('pdfBlob' + pdfBlob);
HttpRequest req3 = new HttpRequest();
req3.setEndpoint(ChunkUri);
req3.setMethod('POST');
req3.setHeader('Authorization','Bearer ' + token);
req3.setHeader('Content-Length', String.valueOf(attachmentBody.length()));
req3.setHeader('Content-Encoding', 'UTF-8');
req3.setHeader('Content-type', 'application/pdf');
req3.setHeader('Connection', 'keep-alive');
req3.setBodyAsBlob(pdfBlob);
Http http3 = new Http();
HttpResponse response3 = http3.send(req3);
System.Debug(response3.getBody());
How to solve the issue?

Login to Docusign API through apex

I am trying to connect to Docusign REST API making 'login_information' call from the Salesforce developers console, but having an issue:
'The URL provided does not resolve to a resource'.
Here is my code:
private static final string TOKEN_URL = 'https://demo.docusign.net/restapi/v2/login_information';
private static final string userName = 'username';
private static final string password = 'password';
private static final string integrationKey = 'integrationKey';
string authenticationHeader =
'<DocuSignCredentials>' +
'<Username>' + userName+ '</Username>' +
'<Password>' + password + '</Password>' +
'<IntegratorKey>' + integrationKey + '</IntegratorKey>' +
'</DocuSignCredentials>';
HttpRequest req = new HttpRequest();
HttpResponse res = new HttpResponse();
Http http = new Http();
req.setEndpoint(TOKEN_URL);
req.setHeader('Content-Type', 'application/json');
req.setHeader('Accept', 'application/json');
req.setHeader('X-DocuSign-Authentication', authenticationHeader);
req.setMethod('GET');
req.setBody('');
res = http.send(req);
I am able to log in to Docusign Console using my credentials, so all is correct. But can't do the same through Apex. Could it be lack of permissions?
req.setBody(''); should be removed from code. It fixed the problem.

Cannot send a content-body with this verb-type. error while getting response when trying to Upload file in Box Storage

When i am trying to upload files in Box Storage using api provided by Box but at response time i am getting this error
public static void UploadFileRequest(string FolderID, string accesstoken)
{
string boundary = string.Format("----------------------------{0}", DateTime.Now.Ticks.ToString("x"));
string filename="C:\\Users\\Administrator\\Desktop\\Text.txt";
HttpWebRequest httpWReq = (HttpWebRequest)WebRequest.Create("https://upload.box.com/api/2.0/files/content");
ASCIIEncoding encoding = new ASCIIEncoding();
string hh = "\"filename=#\"" + filename + "\" "+";"+"";
hh += "parent_id=\"" + FolderID + "\"";
string kj = string.Format(("filename=#" + filename));
byte[] data = encoding.GetBytes(hh);
httpWReq.Headers.Add("Authorization", "Bearer " + accesstoken);
httpWReq.ContentType = "application/json";
httpWReq.ContentLength = data.Length;
using (Stream stream = httpWReq.GetRequestStream())
{
stream.Write(data, 0, data.Length);
}
HttpWebResponse response = (HttpWebResponse)httpWReq.GetResponse();
string responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();
}
Without knowing the Box API, I will assume that the upload should be a POST operation, so you will need to specify the correct HTTP method on your request, before sending it:
httpWReq.Method = "POST";
The Method property defaults to "GET", and GET operations does not normally have a body..
Here is the solution , as C# accepts bytes format and then any Upload is done , i was missing that .. hope it helps
private void UploadBoxFile(string Filename)
{
HttpWebRequest req = HttpWebRequest.Create("https://upload.box.com/api/2.0/files/content") as HttpWebRequest;
req.Method = "POST";
req.Headers.Add("Authorization", "Bearer < Access Token >");
req.ContentType = "multipart/form-data; boundary=\"d174f29b-6def-47db-8519-3da38b21b398\"";
string Content = GetFormatedData(Filename);
req.ContentLength = Content.Length;
using (Stream Writer = req.GetRequestStream())
{
Writer.Write(Encoding.UTF8.GetBytes(Content), 0, Content.Length);
}
req.GetResponse();
}
private string GetFormatedData(string Filename)
{
StringBuilder build = new StringBuilder();
string Id = "d174f29b-6def-47db-8519-3da38b21b398";
build.AppendLine("--" + Id);
build.AppendLine("Content-Disposition: form-data; filename=\"hello1.txt\"; name=\"filename\"");
build.AppendLine("Content-Type: application/octet-stream");
build.AppendLine();
string FileContent = "This is a sample text";
build.AppendLine(FileContent);
build.AppendLine("--" + Id);
build.AppendLine("Content-Disposition: form-data; name=\"folder_id\"");
build.AppendLine();
build.AppendLine("0");
build.AppendLine("--" + Id + "--");
return build.ToString();
}

using HTTPRequest setPayload in google app engine

I am trying to do HTTPRequest Post via Google App Engine.
This is what I have so far
URL url = new URL("http://myurl.com/myfile.php");
HTTPRequest request = new HTTPRequest(url, HTTPMethod.POST);
request.setPayload(########);
HTTPResponse response = URLFetchServiceFactory.getURLFetchService().fetch(request);
Here I need to put some paired values (ie. "email","hi#example.com" etc)
Since setPayload accept byte[] I have no idea how to convert my paired values
into byte.
I have searched other posts but I am very stuck.
EDIT:
I have changed to this but it is still not working
byte[] data = ("EMAIL=bo0#gmail.com&TITLE=evolution&COMMENT=comments&PRICE=5000;").getBytes();
try {
URL url = new URL("http://www.bo.x10.mx/nPost.php");
HTTPRequest request = new HTTPRequest(url, HTTPMethod.POST);
request.setPayload(data);
HTTPResponse response = URLFetchServiceFactory.getURLFetchService().fetch(request);
This is what I have on php website.
<?php
include "path/conf.php"; //logging into database works
$tb_name = 'Post';
$EMAIL=$_POST['EMAIL'];
$TITLE =$_POST['TITLE'];
$COMMENT =$_POST['COMMENT'];
$PRICE =$_POST['PRICE'];
if(!isset($EMAIL) || !isset($TITLE ) || !isset($PRICE )|| !isset($COMMENT)){
header('HTTP/1.0 412 Precondition Failed', true, 412);
die('Bad data');
}
$sql="INSERT INTO $tb_name(EMAIL, TITLE, COMMENT, PRICE) VALUES ('$EMAIL', '$TITLE ', '$COMMENT ', '$PRICE ')";
$result=mysql_query($sql);
if($result==TRUE){
echo "successfully inserted into table!";}
else{
echo "error in inserting into table!";
header('HTTP/1.0 500 Internal Server Error', true, 500);}
ob_end_flush();
exit();
?>
EDIT2: This is a working code
try{
byte[] data = ("EMAIL=bo0#gmail.com&TITLE=evolution&COMMENT=comments&PRICE=5000").getBytes("UTF-8");
URL url = new URL("http://www.box.com/nost.php");
HTTPRequest request = new HTTPRequest(url, HTTPMethod.POST);
request.setPayload(data);
HTTPResponse response = URLFetchServiceFactory.getURLFetchService().fetch(request);
}
My database string field is of type UTF-8
You create a String with the request body, and then you get the byte array. For example we have:
URL url = new URL("http://myurl.com/myfile.php");
HTTPRequest request = new HTTPRequest(url, HTTPMethod.POST);
String body = "email=" + email + "&mpla=" + mpla;
request.setPayload(body.getBytes("UTF-8"));
HTTPResponse response = URLFetchServiceFactory.getURLFetchService().fetch(request);
Hope this helps!
