I've answered my own question here. See the first code block where I use php://input to get the posted data.
I'm trying to send a post request from my app to a webserver, and I'm checking for the post vars using PHP:
if( isset( $_POST['name'] ) ){
echo json_encode(['status' => 1]);
}else if( $posted_data = (string) @file_get_contents('php://input') ) {
echo json_encode(['status' => 2]);
}else{
echo json_encode($_POST);
}
The request always returns and empty json encoded array.
I'm using the latest Android Studio, and the latest OkHttp, com.squareup.okhttp3:okhttp:3.4.1. For me, this is like the "Hello World" of OkHttp in Android Studio.
In MainActivity.java:
public void postSomething(View view) {
String url = "https://example.com/json_api_test.php";
String json = "{\"name\":\"cholula\"}";
OkHttpPostHandler handler = new OkHttpPostHandler();
String result = "";
try {
result = handler.execute(url, json).get();
} catch (Exception e) {
e.printStackTrace();
}
displayPostResponse(result + "
");
}
My OkHttpPostHandler.java:
public class OkHttpPostHandler extends AsyncTask<String, Void, String> {
OkHttpClient client = new OkHttpClient();
public static final MediaType JSON
= MediaType.parse("application/json; charset=utf-8");
@Override
protected String doInBackground(String... params) {
RequestBody body = RequestBody.create(JSON, params[1]);
Request request = new Request.Builder()
.url(params[0])
.post(body)
.build();
try {
Response response = client.newCall(request).execute();
return response.body().string();
}
catch( Exception e ){
return "HTTP Request Error";
}
}
}
When I debug, I can see that the params[1] value is the expected json-like string, but that's the last time I see it.
I've tried forming the json in a number of ways, so I'm not sure if that's the problem. I just don't understand why I can't see the posted vars when the post request gets to the server.
How can I see the posted vars on the webserver? What am I doing wrong? I've only been using Android Studio and Java for less than a week, so I have no clue. I've really looked around the internet a lot for the answer, and so posting here is the last resort.
Thanks!
