C#响应：{quot；错误：：-1，“请求”：null}

我正在向一个站点发送post请求。过了一会儿，我得到了这个回答。我注意到流返回了这些错误。 拖缆错误：

我的响应结果

非实际错误，不支持读取。您有一个只写的流。长度和位置不可用（

CanRead

和

CanSeek

都是

false

）。那么我该怎么办？我应该设置为“真”吗？什么？不，你什么都不用做。这是由

GetRequestStream（）

返回的标准流：您只能对其进行写入。您的意思是，您有错误，或者帖子（我不知道

requestHeader.Method

value设置为什么）没有预期的结果？在这种情况下，如果

HttpStatusCode

is>399，WebResponse将返回错误或您有异常。当您发送HttpWebRequest时，您应该始终处理异常（

WebException

，至少是这样）：它遵循（古老的）抛出模式，处理我们不处理的所有内容。它正常工作。过了一会儿，这个错误出现了{“error”：-1，“request”：null}。路标
