从httpwebrequest切换到httpclient,我无法弄清楚如何发送我的标题？

Question

所以,这是我正在使用的代码

    string URL = "http://www.test.com/posts/.json";
    var getInfo = (HttpWebRequest)HttpWebRequest.Create(URL);{
    getInfo.Headers["Cookie"] = CookieHeader;
    getInfo.ContentType = "application/x-www-form-urlencoded";
    using (WebResponse postStream = await getInfo.GetResponseAsync())
    {
        StreamReader reader = new StreamReader(postStream.GetResponseStream());
        string str = reader.ReadToEnd();
    }

我想切换到我已经工作的httpclient,除了它没有传递Cookie信息.我得到的信息,但只是匿名信息.不是我发送的用户的信息.这是我现在拥有的.

    HttpClient client = new HttpClient();
    client.DefaultRequestHeaders.Accept.Add(
    new MediaTypeWithQualityHeaderValue("application/json"));
    client.BaseAddress = new Uri("http://www.test.com/");
    client.DefaultRequestHeaders.Add("Cookie", CookieHeader);
    HttpResponseMessage response = await client.GetAsync("http://www.test.com" + URL);
    string str;
    str = await response.Content.ReadAsStringAsync();

Answer 1

您需要使用a HttpClientHandler,将cookie添加到其中,然后将其传递给HttpClient构造函数.

一个例子:

    Uri baseUri = new Uri("http://www.test.com/");
    HttpClientHandler clientHandler = new HttpClientHandler();
    clientHandler.CookieContainer.Add(baseUri, new Cookie("name", "value"));
    HttpClient client = new HttpClient(clientHandler);
    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
    client.BaseAddress = baseUri;
    HttpResponseMessage response = await client.GetAsync("http://www.test.com" + URL);
    string str2 = await response.Content.ReadAsStringAsync();

我在这里找到了对这个相同行为的引用,声明名为"Cookie"的标题DefaultRequestHeaders被忽略而不被发送,但看起来任何其他值都将按预期工作.
