我正在翻譯一個適用于 C#（Xamarin 應用程式）的 javascript 代碼。我從服務器回傳 400 'Bad Request'
我想知道我用 C# 撰寫的代碼是否正確，或者我遺漏了什么。
JS代碼：
function requestTokens(code) {
var codeVerifier = document.getElementById("codeVerifierValue").innerHTML;
var data = {
"grant_type": "authorization_code",
"client_id": "clientid",
"code": code,
"code_verifier": codeVerifier,
"redirect_uri": "https://redirectUrl"
};
$.ajax({
beforeSend: function (request) {
request.setRequestHeader("Content-type", "application/x-www-form-urlencoded; charset=UTF-8");
},
url: "https://myUrl",
data: data,
success: responseFromPostRequest,
dataType: "json"
});
}
C#代碼：
private HttpClient _httpClient = new HttpClient();
private async Task<string> HttpPost(string url, DataDto data)
{
var jsonData = JsonConvert.SerializeObject(data);
var content = new StringContent(jsonData, Encoding.UTF8, "application/x-www-form-urlencoded");
var response = await _httpClient.PostAsync(new Uri(url), content);
}
謝謝你的幫助

uj5u.com熱心網友回復：
所以我發現在 Content-type application/x-www-form-urlencoded 的情況下，它不應該是粘貼在 post 請求中的 JSON 檔案。
有我發現的代碼：
public static async Task<TResult> PostFormUrlEncoded<TResult>(string url, IEnumerable<KeyValuePair<string, string>> postData)
{
using (var httpClient = new HttpClient())
{
using (var content = new FormUrlEncodedContent(postData))
{
content.Headers.Clear();
content.Headers.Add("Content-Type", "application/x-www-form-urlencoded");
HttpResponseMessage response = await httpClient.PostAsync(url, content);
return await response.Content.ReadAsAsync<TResult>();
}
}
}
有了這個它完美地作業
