上传文件到SharePoint返回413请求实体过大

试图从ASP.Net Web应用程序上传文件到SharePoint站点时，我得到一个错误上传文件到SharePoint返回413请求实体过大

A Web exception occurred while attempting to issue the request. The remote server returned an error: (413) Request Entity Too Large.:

。用户添加通过ASP.Net文件上传控件选择一个文件，下面的代码将其上传到Sharepoint。我想上传的文件是〜250k（即不是很大）。

的代码如下：

public string SharepointWebClientSOAPPost(Uri webService, string SOAPAction, string contentType, string postData, NetworkCredential networkCredential = null, string webProxy = "", NetworkCredential webserviceCredentials = null) 
{ 
    try 
    { 
     using (WebClient client = new WebClient()) 
     { 
      if (string.IsNullOrEmpty(webProxy) && webserviceCredentials != null) 
      { 
       client.Proxy = new WebProxy(new Uri(webProxy)); 
       client.Proxy.Credentials = webserviceCredentials; 
      } 
      if (networkCredential != null) 
      { 
       client.Credentials = networkCredential; 
      } 

      client.Headers.Add(HttpRequestHeader.ContentType, contentType); 
      client.Headers.Add("SOAPAction", SOAPAction); 

      // Apply ASCII Encoding to obtain the string as a byte array. 
      var byteArray = Encoding.ASCII.GetBytes(postData); 

      // Upload the input string using the HTTP 1.0 POST method. 
      var responseArray = client.UploadData(webService, "POST", byteArray); 

      // Decode and return the response. 
      var response = Encoding.ASCII.GetString(responseArray); 
      return response; 
     } 
    } 
    catch(Exception ex) 
    { 
     //etc. 
    } 
}

我有以下在web.config设置

<httpRuntime maxRequestLength="1024000" />

，如果我用一个文本文件，是几k它工作正常，所以我认为基本思想是正确的（SOAP消息格式正确，URL正确）。但是，运行SP站点的人员告诉我，它配置为接受最大为50MB大小的文档。

任何想法，我可以开始寻找问题？

你的代码中使用WCF上传文件，而不是ASP.NET为此，你必须配置的web.config maxReceivedMessageSize这样的：

<system.serviceModel> 
    <bindings> 
    <basicHttpBinding> 
     <binding maxReceivedMessageSize="10485760"> 

     </binding> 
    </basicHttpBinding> 
    </bindings> 
</system.serviceModel>

道歉在我的响应延迟 - 但这不工作（同错误）。该网站没有托管服务，因此我不认为这个错误是'接收'，而是'发送' – glosrob 2014-10-10 11:47:14
