Hello wrote a web api in C # to authenticate, using postman sent the parameters and returns the token correctly, I will leave at the end of post the parameters for testing, and searched for a number of code to bring parameters in JSON from an web api always send me back the Código 400 Bad request , I just want to connect from < strong> Java using the user and the password so that the server returns the token generated for that login I used many code and still nothing, this is the token that I can generate using the postman but from Java I can only generate 400 bad request .
I'm trying to authenticate to use it in an app for Android
{
"access_token": "...",
"token_type": "bearer",
"expires_in": 86399
}url token: http://pedidostf.azurewebsites.net/token
username : admin
password : *****
grant_type : ********
This would be the last method I'm using for the connection
private class POST extends AsyncTask<String, Void, String> {
@Override
protected String doInBackground(String... params) {
// InputStream inputStream = null;
String cliente = params[0];
String clave = params[1];
String json = "";
try {
OkHttpClient client = new OkHttpClient();
Request.Builder builder = new Request.Builder();
builder.url(AppConfig.URL_TOKEN);
builder.addHeader("Content-Type", "application/x-www-form-urlencoded");
FormBody.Builder parameters = new FormBody.Builder();
parameters.add("grant_type", "password");
parameters.add("username", cliente);
parameters.add("password", clave);
builder.post(parameters.build());
Response response = client.newCall(builder.build()).execute();
if (response.isSuccessful()) {
json = response.body().string();
System.out.println("CONTENIDO:: " + json);
}
} catch (Exception e) {
e.printStackTrace();
System.out.println("Error: " + e);
}
return json;
}
I got it here
