I'm translating a javascript code that works to a C# (Xamarin application). And I getback from the server 400 'Bad Request'
I would like to know if the code I wrote in C# is correct or I missing something.
JS code:
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# code:
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);
}
Thanks for your help

CodePudding user response:
So I found out that in the case of Content-type application/x-www-form-urlencoded it should not be a JSON file to be pasted in the post request.
There is the code sniped I found :
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>();
}
}
}
With this it works perfectly
