添加授权报头 [英] Adding authorization to the headers

问题描述

我有以下的code：

...
AuthenticationHeaderValue authHeaders = new AuthenticationHeaderValue("OAuth2", Contract.AccessToken);
string result = await PostRequest.AuthenticatedGetData(fullUrl, null, authHeaders);
return result; 
...

public static async Task<string> AuthenticatedGetData(string url, FormUrlEncodedContent data, AuthenticationHeaderValue authValue)
{

    HttpClient client = new HttpClient();
    client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue(authValue.Parameter);

    HttpResponseMessage response = await client.PostAsync(new Uri(url), data);

    response.Content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
    response.EnsureSuccessStatusCode();
    string responseBody = await response.Content.ReadAsStringAsync();
    return responseBody;
}

响应=等待部分只是继续正在进行的循环，并没有任何反应。任何想法我做错了吗？

The response = await part just continues an ongoing loop and nothing happens. Any ideas what I am doing wrong?

真正的问题是，我该如何发送以下标题：

The question really is, how do I send the following header:

Authorization: OAuth2 ACCESS_TOKEN

到外部Web API

to an external web api

推荐答案

这行

client.DefaultRequestHeaders.Authorization = 
           new AuthenticationHeaderValue(authValue.Parameter);

会产生这个头值

Authorization: ACCESS_TOKEN

其中， ACCESS_TOKEN 是 authValue.Parameter 的价值。你想分配给你传递的值，而不是得到所需要的头

Where ACCESS_TOKEN is the value of authValue.Parameter. You want to assign the value you passed instead to get the required header

client.DefaultRequestHeaders.Authorization = authValue;

会产生

Authorization: OAuth2 ACCESS_TOKEN
