展望试图更新微博状态时失败

问题描述

我似乎无法推测这一个。无论我做什么，我不断收到一个417预期失败的错误。无论我已经看了说我需要摆脱对于HttpWebRequest的期望头。设置在Web请求的静态属性 ServicePointManager.Expect100Continue = FALSE 或实例属性 request.ServicePoint.Expect100Continue = FALSE 从来没有得到的摆脱了头。我必须手动将其设置为null将其删除。

不管是什么，虽然，我仍然得到417错误。我在想什么？

 私有静态只读MessageReceivingEndpoint UpdateStatusEndpoint
       =新MessageReceivingEndpoint（http://twitter.com/statuses/update.xml，HttpDeliveryMethods.PostRequest）;

公共静态的XDocument UpdateStatus（ConsumerBase叽叽喳喳，串accessToken，字符串消息）
{
    VAR数据=新字典＆LT;字符串，字符串＆GT;（）;
    data.Add（状态，邮件）;
    ServicePointManager.Expect100Continue = FALSE; //不工作
    HttpWebRequest的要求=微博prepareAuthorizedRequest（UpdateStatusEndpoint，accessToken，数据）。

    request.ServicePoint.Expect100Continue = FALSE; //设置在这里也不管用

    //request.Expect仍定在这一点上，除非我明确地将它设置为null。

    request.Expect = NULL;
    VAR响应= twitter.Channel.WebRequestHandler.GetResponse（要求）; //抛出异常
    返回XDocument.Load（XmlReader.Create（response.GetResponseReader（）））;
}
 

解决方案

DotNetOpenAuth不设置或直接支持Except100Continue。将是很好，如果有一个在通道类的属性。

您的来电'prepareAuthorizedRequest'之前，补充一点：

 （（HttpWebRequest的）WebRequest.Create
（UpdateStatusEndpoint.Location））ServicePoint.Expect100Continue = FALSE;
 

Except100Continue取决于被叫URL中设置。所以，你可以将它设置在创建连接之前。你甚至可以将它在全球范围内配置文件。

 ＆LT; system.net＆GT;
    ＆LT;设置＆gt;
      ＆LT; servicePointManager expect100Continue =FALSE/＆GT;
    ＆LT; /设置＆gt;
  ＆LT; /system.net>
 

I can't seem to figure this one out. No matter what I do, I keep getting a "417 Expectation failed" error. Everywhere I've looked says that I need to get rid of the Expect header for the HttpWebRequest. Setting the static property ServicePointManager.Expect100Continue = false or the instance property on the web request request.ServicePoint.Expect100Continue = false never get's rid of the header. I have to manually set it to null to remove it.

No matter what though, I STILL get the 417 error. What am I missing?

private static readonly MessageReceivingEndpoint UpdateStatusEndpoint
       = new MessageReceivingEndpoint("http://twitter.com/statuses/update.xml", HttpDeliveryMethods.PostRequest);

public static XDocument UpdateStatus(ConsumerBase twitter, string accessToken, string message)
{
    var data = new Dictionary<string, string>();
    data.Add("status", message);
    ServicePointManager.Expect100Continue = false; //Doesn't work
    HttpWebRequest request = twitter.PrepareAuthorizedRequest(UpdateStatusEndpoint, accessToken, data);

    request.ServicePoint.Expect100Continue = false; //setting here doesn't work either

    //request.Expect is still set at this point unless I explicitly set it to null.

    request.Expect = null;
    var response = twitter.Channel.WebRequestHandler.GetResponse(request); //Throws exception
    return XDocument.Load(XmlReader.Create(response.GetResponseReader()));
}

解决方案

DotNetOpenAuth doesn't set or support Except100Continue directly. Would be nice if there is a property in the Channel class.

Add this before your call to 'PrepareAuthorizedRequest':

    ((HttpWebRequest)WebRequest.Create
(UpdateStatusEndpoint.Location)).ServicePoint.Expect100Continue = false;

Except100Continue is set depending on the called URL. So you can set it before the connection is created. You may even set it globally in the config file.

  <system.net>
    <settings>
      <servicePointManager expect100Continue="false" />
    </settings>
  </system.net>
