如何在 webclient 的 post 请求中发送 x-www-form-urlencoded？

Question

我知道我可以发送 json 但我找不到如何发送 x-www-form-urlencoded。我不知道该尝试什么，因为我找不到任何东西。

WebClient wc = new WebClient();


string data = "channel_id=+12039273888&channel_type=phone&channel_verification=514950";

wc.Headers[HttpRequestHeader.ContentType] = "application/x-www-form-urlencoded";

string result = wc.UploadString("http://3.86.171.88/api/login", data);

System.Console.WriteLine(result);

Answer 1

您可以在 WebClient class 上使用 UploadString() 方法，例如

string data = "name=john&age=20&city=Uganda";
using (WebClient client = new WebClient())
{
    client.Headers[HttpRequestHeader.ContentType] = "application/x-www-form-urlencoded";
    string result = client.UploadString(url of api resource, data);
}

Answer 2

        HttpClient client = new HttpClient();

        HttpContent content = new FormUrlEncodedContent(
            new List<KeyValuePair<string, string>>()
            );

        content.Headers.ContentType = new MediaTypeHeaderValue("application/x-www-form-urlencoded");
        content.Headers.ContentType.CharSet = "UTF-8";
        client.DefaultRequestHeaders.ExpectContinue = false;
        HttpResponseMessage response = await client.PostAsync(new Uri(https://some url...), content);

希望这有帮助..因为 HttpClient 是最新的也更倾向于 restapi..
