Windows Server 2008 R2，WCF服务上载不适用于HTTPS [英] Windows Server 2008 R2 , WCF service Uploading not working for HTTPS

问题描述

大家好，



我在Windows Server 2008 R2上安装了IIS，并托管了一个wcf服务。

我创建了自签名证书并使用安全的http连接来访问服务。

我正在使用服务将图像从移动设备上传到服务器。

小尺寸图像上传到服务器（图像大小<1000KB），大小超过1MB限制服务调用是通过错误。

这是一种服务电话方式：

Hi All,

I had installed an IIS on Windows server 2008 R2 , and hosted an wcf service.
I had created a self signed certificate and using a secure http connection to access service.
I am using service to upload images from mobile devices to server.
The small size image is uploading to server (image size < 1000KB) , it the size exceeds 1MB limit the service call is through an error.
Here is a service call method :

jsonText = JSON.stringify({"ImageData":ImageData});

    var url = getURL()+"UplodImage";

    var xhr = createCORSRequest('POST', url);
   if (!xhr) {
         alert('CORS not supported');
       }

   xhr.onload = function () {
           var data = JSON.parse(xhr.responseText);

   };
   xhr.onerror = function() {
           alert('Woops, there was an error making the request.');
       };
       xhr.setRequestHeader('Content-Type', 'application/json') ;
       xhr.send(jsonText);
   }

总是大文件大小我收到xhr.onerror（）错误消息。



这里可能出现什么问题？



我也尝试过使用HTTP服务的HTTP服务图像上传到服务器，那么还需要为HTTPS做任何额外设置吗？



这是来自Wcf服务的配置文件：

Always for large file size I am getting an "xhr.onerror()" error message.

What may be the issue here?

I had also tried with HTTP service, with HTTP service images were uploading to server, So it there any extra settings required to do for HTTPS ?

Here is configuration file from Wcf service :

推荐答案

您需要根据您的要求增加上传文件大小限制。并且它适用于web.config中的更改

you need to increase upload file size limit as per your requirement. and its realted to changes in web.config

<system.web>
    <httpruntime maxquerystringlength="2097151" maxurllength="2097151" maxrequestlength="2097151" />
  </system.web>

maxRequestLength [ ^ ]





也可以像
