I send HTTP request to a webpage to insert or retrieve data.

This is my code:

string json = JsonConvert.SerializeObject(user);
using (var client = new HttpClient())

 var response = client.PostAsync(
 "url",
 new StringContent(json, Encoding.UTF8, "application/json"));


DisplayAlert("Alert", json, "OK");
DisplayAlert("test", response, "test");

For this particular example; the website should return true or false.

But I want to read the response variable.

The DisplayAlert("test", response, "test"); show error. And this is because I am trying to read response outside of scope.

My question is how to read the response variable or output response variable on the page?

Edit

 LoginModel user = new LoginModel();
 
 user.email = email.Text;
 user.password = password.Text;

 ;

 string json = JsonConvert.SerializeObject(user);

 using (var client = new HttpClient())
 


 

 var response = client.PostAsync(
 "https://scs.agsigns.co.uk/tasks/photoapi/login-photoapi/login-check.php",
 new StringContent(json, Encoding.UTF8, "application/json"));


 DisplayAlert("Alert", json, "OK");
 DisplayAlert("test", response, "test");

This gives you an error because you try to access a variable which is declared inside of a different scope. If you move the variable response inside of the "method scope" the error will disappear:

string json = JsonConvert.SerializeObject(user);

HttpResponseMessage response;
using (var client = new HttpClient())

 response = await client.PostAsync(
 "url",
 new StringContent(json, Encoding.UTF8, "application/json"));


DisplayAlert("Alert", json, "OK");
DisplayAlert("test", await response.Content.ReadAsStringAsync(), "test");

Note the await which I added just before client.PostAsync() (You will find more infos about async/await in the docs).

To get the string representation of the response content you can use following method:

await response.Content.ReadAsStringAsync(); 

This will read the response content as string.

string json = JsonConvert.SerializeObject(user);
HttpResponseMessage response;
using (var client = new HttpClient())

 response = client.PostAsync(
 "url",
 new StringContent(json, Encoding.UTF8, "application/json").Result);

var body = response.Content.ReadAsStringAsync().Result;
DisplayAlert("Alert", json, "OK");
DisplayAlert("test", body, "test");

should work, by moving the declaration of the variable outside the scope, and updating the value inside the call.
