我有以下代码，我想将发布请求的授权设置为：

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();
         }
     }
}

这个怎么做？我真的很挣扎和下面的声明

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

抛出以下异常

System.Net.Http.dll 中出现“System.FormatException”类型的异常，但未在用户代码中处理

我通过以下代码行解决了这个问题。

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

不确定这是否仍在运行，但基本身份验证密钥和类似 64 哈希身份验证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);

我遇到了同样的问题，我使用以下方法解决了：

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

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

其中后面的字符串Basic是来自 Postman 的编码字符串，选项是“代码”。

我希望这有帮助！
