设置 HttpClient 的授权头

Question

我有以下代码，我想将 post 请求的授权设置成这样：

Authorization:key=somevalue

using (HttpClient client = new HttpClient())
{
     using (StringContent jsonContent = new StringContent(json))
     {
         jsonContent.Headers.ContentType = new MediaTypeHeaderValue("application/json");

         using (HttpResponseMessage response = await client.PostAsync("https://android.googleapis.com/gcm/send", jsonContent))
         {
            var reponseString = await response.Content.ReadAsStringAsync();
         }
     }
}

如何做到这一点？我真的很挣扎以及以下语句

client.DefaultRequestHeaders.Add("Authorization", "key=" + apiKey);

抛出以下异常

An exception of type 'System.FormatException' occurred in System.Net.Http.dll but was not handled in user code

Answer 1

我通过以下代码行解决了这个问题。

client.DefaultRequestHeaders.Authorization =
       new AuthenticationHeaderValue("key", "=" + apiKey);

Answer 2

我遇到了同样的问题，我使用 :

解决了

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(endPoint);

request.Headers["Authorization"] = "Basic jMxMTgwMWUzYWFkYTk4NjM2MjcyOTk3MDowYTU0N2I2NzliNWRkMjliN2I4NTFlMDBkY2Y2NjQzNzQ5OTIxYzZl";

其中Basic后的字符串是来自Postman的编码字符串，选项为'code'。

希望对您有所帮助！

不确定这是否仍然是运行，但基本授权密钥和类似 64 哈希授权密钥的内容将添加到类似 REST 调用的内容中，例如：

var httpClient2 = new HttpClient();
var uri = new Uri("<someuri>");
var tokenKey = "<sometokenkey>");
var httpContent = new StringContent("<some body or serialized thing>", System.Text.Encoding.UTF8, "application/json");

httpClient2.BaseAddress = new Uri(uri);
httpClient2.DefaultRequestHeaders.Accept.Clear();
httpClient2.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
httpClient2.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", tokenKey);

response = await httpClient2.PostAsync(uri, httpContent);
