Question

我有以下代码，它将XML提交给第三方Web服务，这些错误（故意，此刻）在＆＃34; req.GetResponse（）＆＃34;有错误，详情如下。

byte[] bytes = Encoding.ASCII.GetBytes(myXMLData);
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(myWebsite);
using (Stream os = req.GetRequestStream())
{
    os.Write(bytes, 0, bytes.Length);
}
WebResponse response = req.GetResponse();
string responseStream = StringFromResponseStream(response);

GetResponse（）的错误

抛出异常：＆＃39; System.New.WebExtension＆＃39;在System.dll中附加信息：远程服务器返回错误：（400）错误请求

当我在Fiddler中跟踪此调用时，我可以看到来自该服务的响应，还包括一个更有用的错误（下面; RAW视图），我试图找到它：

HTTP/1.1 400 Bad Request

No supported action 'SomeName' available for 'SomeValue'

观看＆＃39;关于变量似乎并没有表明我可能从中得到这个（并且很可能是我忽略的简单）

Answer 1

最终找到了解决方案;其中'result'包含流程中的内容;还有更多工作要做，但这是我需要的基础知识。

using (var httpClient = new HttpClient())
{
    httpClient.BaseAddress = new Uri(myWebSite);
    httpClient.DefaultRequestHeaders.Accept.Clear();
    httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("text/xml"));

    StringContent stringContent = new StringContent(myXMLData);
    stringContent.Headers.ContentType = new MediaTypeHeaderValue("text/xml");
    HttpResponseMessage httpResponseMessage = httpClient.PostAsync(httpClient.BaseAddress, stringContent).Result;

    string result = httpResponseMessage.Content.ReadAsStringAsync().Result;
}

从（第三方）Web服务捕获响应信息时出错
