我正在尝试设置Cookie并从一般方法中获取Cookie。我看到这个例子有效但我在修改自己的代码方面遇到了麻烦,我可以保留我的一般功能。
CookieContainer cookies = new CookieContainer();
HttpClientHandler handler = new HttpClientHandler();
handler.CookieContainer = cookies;
HttpClient client = new HttpClient(handler);
HttpResponseMessage response = client.GetAsync("http://google.com").Result;
Uri uri = new Uri("http://google.com");
IEnumerable<Cookie> responseCookies = cookies.GetCookies(uri).Cast<Cookie>();
foreach (Cookie cookie in responseCookies)
Console.WriteLine(cookie.Name + ": " + cookie.Value);
Console.ReadLine();
我的代码:
public static HttpClient CreateClientASMtoken(string tokenVal)
{
var httpClient = new HttpClient
{
BaseAddress = new Uri(urlASM)
};
httpClient.DefaultRequestHeaders.Accept.Clear();
httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
//httpClient.DefaultRequestHeaders.Accept.Add(new Cookie("token", tokenVal));
return httpClient;
}
评论代码是我实现这一目标的一个方法。我使用的另一种通用方法是:
public static async Task<HttpResponseMessage> PostASM(string path, object content)
{
string tokenVal = "d2GpEA5r8pwLRcOPxgaygPooldz2OZ2HUZzZ0YDPAOYCIiH4u5";
using (var client = CreateClientASMtoken(tokenVal))
{
var json = JsonConvert.SerializeObject(content);
var serializedContent = new StringContent(json, Encoding.UTF8, "application/json");
var postResponse = await client.PostAsync(path, serializedContent);
//string response = await postResponse.Content.ReadAsStringAsync();
return postResponse;
}
}
编辑: 我也试过这个:
但它显示错误,网址正常,令牌也是如此。 在此先感谢:)

要添加Cookie,请更改行:
//httpClient.DefaultRequestHeaders.Accept.Add(new Cookie("token", tokenVal));
为:
httpClient.DefaultRequestHeaders.Add("Set-Cookie", "token=test; path=/");
如果您不想要路径部分,请将其删除。
如果您希望能够从HttpResponseMessage中读出cookie,您需要自己处理解析。
以下是获取所有Cookie的方法:
HttpClient client = CreateClientASMtoken("");
HttpResponseMessage response = client.GetAsync("http://localhost").Result;
IEnumerable<string> rawCookies = response.Headers.GetValues("Set-Cookie");
尝试一下,您将看到它们的格式与设置时相同。如上所述,您需要自己解析它们或找一个类来为您完成此任务。

我找到了一种可以轻松解决问题的方法。感谢那些贡献的人。
public static async Task<string> GetASM(string path)
{
string tokenVal = "d2GpEA5r8pwLRcOPxgaygPooldz2OZ2HUZzZ0YDPAOYCIiH4u5";
Uri uriASM = new Uri(urlASM);
var cookieContainer = new CookieContainer();
using (var handler = new HttpClientHandler() { CookieContainer = cookieContainer })
using (var client = new HttpClient(handler) { BaseAddress = uriASM })
{
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
{
cookieContainer.Add(uriASM, new Cookie("token", tokenVal));
var getResponse = await client.GetAsync(path);
return await getResponse.Content.ReadAsStringAsync();
}
}
}
