The POST method not working CurlSharp. The same does not operate
easy.PostFields> FileUpload.cs not working
easy.HttpPost> BookPost.cs not working
64 Bit

commented

Are you running Windows or Mono Linux/OSX? All the examples you've mentioned are working fine on my end. (Windows 8.1 x64).
Make sure to copy the appropriate DLL for the environment (32/64 bit).
To avoid further confusion, re-target the projects from "Any CPU" to the specific architecture of your choice.

Run on a Windows 2008 Standard R2 - 64 bit and Mono 3.8
GET method, a proxy for these systems work.
The POST method does not send data to the program itself starts, but does not send.
Built in this way

I run the test program, and download the code works. POST does not work send in the 32 Bit and 64 Bit
If possible, ask me about posting your CurlSharp.dll 64 bit that works well for you.
Sorry for English writing by the translator

Hi.
I have similar problem with POST method. I wasn't able to send any data using CURLSHARP. My environment is Win 7 64 bit - compile via "Any CPU" and "x64".

This is my complete C# cod (I've change domain only):

using CurlSharp;
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Net;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApplication1
{

class Program
{

    static void Main(string[] args)
    {
        int bits = IntPtr.Size * 8;
        Console.WriteLine("Test curl {0} bit", bits);
        Curl.GlobalInit(CurlInitFlag.All);
        Console.WriteLine("Curl Version: {0}\n", Curl.Version);

        try
        {

            Console.WriteLine("\n========== TEST 1 CurlEasy Post ============");

            using (var easy = new CurlEasy())
            {

                easy.WriteFunction = OnWriteData;
                easy.WriteData = null;
                easy.PostFields = "parm1=value1&parm2=value2";
                easy.UserAgent = "MyUserAgent CurlEasy Post";
                easy.FollowLocation = true;
                easy.Url = "http://xxxxx.com/testpost.php";
                easy.Post = true;
                var code = easy.Perform();
            }


            Console.WriteLine("\n========== TEST 2 CurlEasy HttpPost ============");

            var mf = new CurlHttpMultiPartForm();
            mf.AddSection(CurlFormOption.CopyName, "parm1", CurlFormOption.CopyContents, "value1", CurlFormOption.End);
            mf.AddSection(CurlFormOption.CopyName, "parm2", CurlFormOption.CopyContents, "value2", CurlFormOption.End);
            using (var easy = new CurlEasy())
            {

                easy.WriteFunction = OnWriteData;
                easy.WriteData = null;
                easy.UserAgent = "MyUserAgent CurlEasy HttpPost";
                easy.FollowLocation = true;
                easy.Url = "http://xxxxx.com/testpost.php";
                easy.HttpPost = mf;
                var code = easy.Perform();
            }  


            Curl.GlobalCleanup();
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex);
        }

        Console.WriteLine("\n========== TEST 3 HttpWebRequest ============");

        var request = (HttpWebRequest)WebRequest.Create("http://xxxxx.com/testpost.php");
        var data = Encoding.ASCII.GetBytes("parm1=value1&parm2=value2");
        request.UserAgent = "MyUserAgent HttpWebRequest";
        request.Method = "POST";
        request.ContentType = "application/x-www-form-urlencoded";
        request.ContentLength = data.Length;

        using (var stream = request.GetRequestStream())
        {
            stream.Write(data, 0, data.Length);
        }

        var response = (HttpWebResponse)request.GetResponse();
        var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();

        Console.WriteLine(responseString);    
        Console.ReadLine();
    }

    public static Int32 OnWriteData(Byte[] buf, Int32 size, Int32 nmemb, Object extraData)
    {
        Console.Write(Encoding.UTF8.GetString(buf));
        return size * nmemb;
    }

    public static Int32 OnHeaderData(Byte[] buf, Int32 size, Int32 nmemb, Object extraData)
    {
        var userData = (string)extraData;
        Console.Write("->"+Encoding.UTF8.GetString(buf));
        return size * nmemb;
    }

    public static void OnDebug(CurlInfoType infoType, String msg, Object extraData)
    {
        // print out received data only
        if (infoType == CurlInfoType.DataIn)
            Console.WriteLine(msg);
    }


    public static void Testowuec()
    {

    }
}

}

And here are the results:

As you can see only HttpWebRequest (TEST 3) sent POST data.
I'm not sure is some problem with CurlSharp, my code or sth else...

@mangusta @http200it The POST bug has been fixed for WIN64. Please see the newly added EasyPost sample application.

Thank you very much for improving CurlSharp 64 bit for POST - PostFields.
:-)

commented

@http200it 32-bit build of CurlSharp uses the libcurlshim.dll helper library which was originally authored by Jeff Phillips. Unfortunately, this library was not ported to WIN64. I'm of little help in this regard as my C and assembly language skills are rusty. The CurlHttpMultiPartForm class is dependent on libcurlshim.dll and does not yet work in non-WIN32 builds.

commented

@ masroore - It is important that it works the ability to send POST data under Linux 64 Bit Net MONO. The primary concern ;)

commented

@http200it @mangusta Now the 64-bit HttpPost (multipart form-data) feature works without libcurlshim helper library.

Output from the EasyPost sample:

It works by sending a POST easy.PostFields and easy.HttpPost on Windows 64 Bit and Linux Debian 7 64 Bit - Mono 3.8. Once again, thank you very much for improving the code.

@masroore - you are great ! -> Thank you :)

commented

@http200it Thanks for confirming the fix on 64-bit Linux. I confirm the PostFields and HttpPost features work on OS X Xamarin as well.

commented

Even setting the parameters works and does not work. I think it should work interchangeably so and so.

//easy.UserAgent = "Do UserAgent"; // Works
easy.SetOpt(CurlOption.UserAgent, "Do UserAgent SetOpt"); // Does not work

//easy.Proxy = "xxx.xxx.xxx.xxx:21320"; // Works
easy.SetOpt(CurlOption.Proxy, "xxx.xxx.xxx.xxx:21320"); // Does not work

//easy.PostFields = postData; // Works :)
easy.SetOpt(CurlOption.PostFields, postData); // Does not work

//easy.Encoding = "gzip, deflate"; // Works
easy.SetOpt(CurlOption.Encoding, "gzip, deflate"); // Does not work

easy.FollowLocation = true; // Works or
easy.SetOpt(CurlOption.FollowLocation, true); // Works

At the time, please check yourself/

commented

@http200it Thanks for reporting the bug. String options were not set properly in the setObjectOptions() method.
Issue #2 is now fixed.

commented

@masroore - Now the function easy.SetOpt (CurlOption. **, ***); works as it should.
Tested on Windows 64bit and Linix 64bit mono.
Thanks again for the quick improvement and help :-)

commented

@masroore thank you very much for your intervention and for whole great job! It's working now. All the best!

commented

Love curl and this .NET port.

However, I try to set option
easy.SetOpt(CurlOption.HttpHeader, "application/soap+xml; charset=utf-8");

but it always shows content-type:
application/x-www-form-urlencoded

commented

@hieple Are you trying to set the content-type header? You can use the ContentType property:

easy.ContentType = "application/soap+xml; charset=utf-8";

FYI, CurlOption.HttpHeader takes a linked list of strings.

commented

But easy.ContentType is read-only

commented

@hieple I stand corrected, ContentType is applicable only to the response from web server.
I could not find any easy way to set the content-type header on the request.
You'll need to construct the HTTP header manually:

var headers = new CurlSlist();
headers.Append("Content-Type: application/soap+xml; charset=utf-8");
easy.HttpHeader = headers;

Hello again. It does not work to send a file or send wrong? My test code:
string avatar = Application.StartupPath + @"\avatary\myface.jpg";
var mf = new CurlHttpMultiPartForm();
mf.AddSection(CurlFormOption.CopyName, "parm1", CurlFormOption.CopyContents, "value1", CurlFormOption.End);
mf.AddSection(CurlFormOption.CopyName, "parm2", CurlFormOption.CopyContents, "value2", CurlFormOption.End);
if (File.Exists(avatar))
{
mf.AddSection(CurlFormOption.CopyName, "uploadedfile", CurlFormOption.File, avatar, CurlFormOption.ContentType, "application/octet-stream", CurlFormOption.End);
Console.WriteLine(avatar);
}
easy.HttpPost = mf;

$value) { echo "$header: $value \r\n"; } ?>

My OUT:

[parm1] => value1
[parm2] => value2
