maigun 回复 OK 但没有任何反应

Question

使用 x-www-from-urlencoded 和基本身份验证在 Postman 上一切正常。现在尝试弄脏我的手，我只得到状态代码 200，mailgun 上什么也没有，没有记录日志。

using (var client = new HttpClient())
{
  client.BaseAddress = new Uri("https://api.mailgun.net/v3");

  client.DefaultRequestHeaders.Authorization = 
     new AuthenticationHeaderValue("api", "key-withheld-till-a-verdict-has-passed");

  var msg = new List<KeyValuePair<string, string>>
  {
    new KeyValuePair<string, string>("from",
        $"Excited User <mailgun@sandboxSOMEGUIDHERE.mailgun.org>"),
    new KeyValuePair<string, string>("to","approved-to-receive@mailgun"),
    new KeyValuePair<string, string>("subject", "Test Please Do Not Reply"),
    new KeyValuePair<string, string>("text","Thanks for borrowing me your inbox")
  };

  var request = new HttpRequestMessage(HttpMethod.Post, 
     "sandboxSOMEGUIDHERE.mailgun.org/messages");

  request.Content = new FormUrlEncodedContent(msg);

  var response = await client.SendAsync(request);
  // I get 200 status code

  var result = await response.Content.ReadAsStringAsync(); 
  //I get result = "Mailgun Magnificent API"         
}

Answer 1

首先，我得到了 BaseAddress not right。我不得不在 BaseAddress.

的末尾放置一个斜杠

 client.BaseAddress = new Uri("https://api.mailgun.net/v3/");

没有斜杠，我是 posting 到（注意缺少 v3），

https://api.mailgun.net/sandboxSOMEGUIDHERE.mailgun.org/messages

整理之后，又出现了一个问题401 - ANAUTHORIZED。在这个的帮助下，我做到了，

var byteArray = new UTF8Encoding()
    .GetBytes("api:key-withheld-till-a-verdict-has-passed");
client.DefaultRequestHeaders.Authorization =
     new AuthenticationHeaderValue("Basic", Convert.ToBase64String(byteArray));

但 mailgun 回复 Ok 的原因仍然是个谜。为了进一步调查，我使用 Postman 到 post 到

https://api.mailgun.net/sandboxSOMEGUIDHERE.mailgun.org/messages

令我惊讶的是，Mailgun 神秘地回复了 Ok。
