随机Indy ResponseCode = -1 / EIdSocketError Socket错误＃0异常

问题描述

我有一个delphi代码，基本上使用 Indy 10.4.704 将文件上传到远程安全服务器：

  IdHTTP：= TIdHTTP.Create（nil）; 
 try 
 TheCompressor：= TIdCompressorZLib.Create（nil）; 
 TheSSL：= TIdSSLIOHandlerSocketOpenSSL.Create（nil）; 
 
 with IdHTTP do 
 begin 
 HTTPOptions：= [hoForceEncodeParams]; 
 AllowCookies：= True; 
 HandleRedirects：= True; 
协议版本：= pv1_1; 
 
 IOHandler：= TheSSL; 
压缩器：= TheCompressor; 
结束// with 
 
 //获取上传简历偏移量
 try 
 IdHttp.Head（'https://www.domain.com/my-file.bin'）; 
 if（IdHttp.Response.ResponseCode<> 404）And（IdHttp.Response.ContentLength> = 0）then 
 StartPos：= IdHttp.Response.ContentLength 
 else 
 StartPos：= 0; 
除了
 StartPos：= 0; 
结束// try / except 
 
 //上传文件
 TheFile：= TFileStream.Create（FileName，fmOpenRead OR fmShareDenyWrite）; 
 RangeStream：= TIdHTTPRangeStream.Create（TheFile，StartPos，-1，True）; 
 try 
 if（RangeStream.ResponseCode = 206）then 
 IdHTTP.Post（https://www.domain.com/upload.php'，RangeStream）; 
 finally 
 RangeStream.Free; 
结束// try / finally 
 finally 
 FreeAndNil（IdHTTP）; 
结束// try / finally 
  

问题是有时代码失败Indy抛出一个 EIdSocketError Socket错误＃0 异常（ idHTTP.ResponseCode 为-1）

连接，我推出了一个EC2 Windows实例，并测试了我的代码（Windows实例在云上运行，所以我假设连接不是一个问题），但我有同样的问题！ p>

错误似乎是随机的，有时上传工作，有时不是。我使用TidLogFile调试，我可以找到这样的东西：

  Stat Connected。 
发送4/26/2012 4:18:42：POST /app/upload.php ... 
发送4/26/2012 4:18:42：< uploaded_file_data_here> 
 Stat Disconnected。 
  

任何人都知道导致这个/如何解决这个问题？

编辑

我。我已经很多了，似乎这不是一个SSL错误。

解决方案

请升级到最新的Indy 10版本， 10.5.8 r4743 。一年前，与错误代码0相关的SSL相关问题已修复。

I have a delphi code that basically upload files to remote secure server using Indy 10.4.704:

 IdHTTP                 := TIdHTTP.Create(nil);
 try
    TheCompressor       := TIdCompressorZLib.Create(nil);
    TheSSL              := TIdSSLIOHandlerSocketOpenSSL.Create(nil);

    with IdHTTP do
    begin
         HTTPOptions     := [hoForceEncodeParams];
         AllowCookies    := True;
         HandleRedirects := True;
         ProtocolVersion := pv1_1;

         IOHandler       := TheSSL;
         Compressor      := TheCompressor;
    end;    // with

    // Get upload resume offset
    try
       IdHttp.Head('https://www.domain.com/my-file.bin');
       if (IdHttp.Response.ResponseCode <> 404) And (IdHttp.Response.ContentLength >= 0) then
          StartPos   := IdHttp.Response.ContentLength
       else
           StartPos  := 0;
    except
          StartPos   := 0;
    end;    // try/except

    // Upload File
    TheFile          := TFileStream.Create(FileName, fmOpenRead OR fmShareDenyWrite);
    RangeStream      := TIdHTTPRangeStream.Create(TheFile, StartPos, -1, True);
    try
       if (RangeStream.ResponseCode = 206) then
          IdHTTP.Post(https://www.domain.com/upload.php', RangeStream);
    finally
           RangeStream.Free;
    end;    // try/finally
 finally
        FreeAndNil(IdHTTP);
 end;    // try/finally

The problem is that sometimes the code fails with Indy throwing a EIdSocketError Socket Error # 0 exception (idHTTP.ResponseCode is -1)

Given my crappy internet connection, I launched an EC2 windows instance and tested my code on it (the windows instance is running on the cloud, so I assume connection is not a problem), yet I got the same issue!

The error seems to be random, sometimes upload works, sometimes not. I debugged with TidLogFile, all I could find is something like this:

Stat Connected.
Sent 4/26/2012 4:18:42: POST /app/upload.php...
Sent 4/26/2012 4:18:42: <uploaded_file_data_here>
Stat Disconnected.

Anyone knows what's causing this/how to fix this?

EDIT

I traced the exception back to TIdSSLIOHandlerSocketOpenSSL. I googled a lot, it seems that it's not an SSL error.

解决方案

Please upgrade to the latest Indy 10 version, which is 10.5.8 r4743. SSL-related issues with Error Code 0 were fixed over a year ago.
