我目前正在使用此脚本来获取HTTP响应标头.
I am currently using this script to get HTTP response headers.
public static List<string> GetHttpResponseHeaders(string url) { List<string> headers = new List<string>(); WebRequest webRequest = HttpWebRequest.Create(url); using (WebResponse webResponse = webRequest.GetResponse()) { headers.Add("Status Code: " + (int) ((HttpWebResponse) webResponse).StatusCode); } return headers; }具体来说,Status Code:是我感兴趣的.如此说来,看来StatusCode()实际上并没有返回状态码",并且在成功请求时,它仅返回了OK而不是一个200.
Specifically, Status Code: is what I am interested in. With that said, it appears that StatusCode() doesn't actually return a "status code," and on successful requests, it only returns an OK instead of a 200.
有没有办法强迫它返回实际代码而不是描述?
Is there a way to force it to return the actual code instead of a description?

话虽如此,看来StatusCode()实际上并没有返回状态码",并且在成功请求时,它仅返回OK而不是200.
With that said, it appears that StatusCode() doesn't actually return a "status code," and on successful requests, it only returns an OK instead of a 200.
否,它将返回 HttpStatusCode 枚举值.如果对具有名称的枚举值调用ToString,它将返回名称.
No, it returns an HttpStatusCode enum value. If you call ToString on an enum value that has a name, it will return the name.
避免这种情况的最简单方法是将其强制转换为int:
The simplest way of avoiding that is just to cast it to int:
headers.Add("Status Code: " + (int) ((HttpWebResponse) webResponse).StatusCode);或者为使块的其余部分更清洁,请对响应进行一次投放:
Or to make the rest of the block cleaner, cast the response once:
using (WebResponse webResponse = webRequest.GetResponse()) { var httpResponse = (HttpWebResponse) webResponse; headers.Add("URL: " + url); headers.Add("Status Code: " + (int) httpResponse.StatusCode); headers.Add("Status Description: " + httpResponse.StatusDescription + "\n"); }(请注意,当您使用字符串连接时,如有必要,将隐式调用ToString,这绝对不值得调用已经为字符串的StatusDescription之类的东西.)
(Note that when you're using string concatenation, ToString will be called implicitly if necessary - and it's never worth calling on something like StatusDescription which is already a string.)
