如何使用 WebClient.UploadValues 方法通过 HTTP POST 发送字符串数组？
我需要使用 HTTP Post 发送字符串数组，如下所示...
Dim wc As New Net.WebClient
Dim NC As New Specialized.NameValueCollection
NC.Add("api_user", "some user")
NC.Add("api_key", "some key")
NC.Add("from", "[email protected]")
NC.Add("subject", "testing...")
NC.Add("body", "testing...again")
NC.Add("to", string_array)
我尝试了几种方法，但我不断收到 - 远程服务器返回错误：(400) 错误请求。
我正在通过他们的 WebAPI 发布到 SendGrid

如果您收到 404，则很可能意味着您的应用程序中的服务 URL 不正确或该服务当前未运行。您能否复制应用程序中的 URL 并将其粘贴到浏览器地址区域中，看看是否可以直接访问它？
If you are receiving a 404, then that most likely means that either the URL in your application for their service is incorrect or the service is not currently running. Can you copy the URL that is in your application and paste it into a browser address area to see if you can access it directly?
