在 android 中发出 HTTP/1.1 GET 请求

Question

I am trying to request data from an API.The requirements of the API are given below:

Base-URL for our API is https://api.openload.co/1 (note the 1 for version 1 behind the /)

All requests to the API shall be HTTP/1.1 GET

Please make sure to use the API with https only.

Most requests require a API Login & API Key, you can find both in the User Panel at the "User Settings" Tab. Response is json, structure is as follows:

 { "status": <status-code>, "msg": "<informational message. might vary, use the status code in your code!>", "result": <result of the request. varies depending on the request> }

I'm using the following method to get the json response:

private static String makeHttpRequest(URL url) throws IOException {
    String jsonResponse = "";

    // If the URL is null, then return early.
    if (url == null) {
        return jsonResponse;
    }

    HttpsURLConnection urlConnection = null;
    InputStream inputStream = null;
    try {

        urlConnection = (HttpsURLConnection) url.openConnection();
        urlConnection.setReadTimeout(10000 /* milliseconds */);
        urlConnection.setConnectTimeout(15000 /* milliseconds */);
        urlConnection.setRequestMethod("GET");
        urlConnection.connect()

        // If the request was successful (response code 200),
        // then read the input stream and parse the response.
        if (urlConnection.getResponseCode() == 200) {
            inputStream = urlConnection.getInputStream();
            jsonResponse = readFromStream(inputStream);
        } else {
            Log.e(LOG_TAG, "Error response code: " + urlConnection.getResponseCode());
        }
    } catch (IOException e) {
        Log.e(LOG_TAG, "Problem retrieving the earthquake JSON results.", e);
    } finally {
        if (urlConnection != null) {
            urlConnection.disconnect();
        }
        if (inputStream != null) {
            // Closing the input stream could throw an IOException, which is why
            // the makeHttpRequest(URL url) method signature specifies than an IOException
            // could be thrown.
            inputStream.close();
        }
    }
    return jsonResponse;
}

But I'm recieveing the response code 403. I'm using the below url to test it: https://api.openload.co/1/account/info?login= {login}&key={key}

When requesting from chrome, the response is obtained in form of a file.Could that be causing the issue as I'm expecting a json response String and the server is returning a file containing the json?

Could someone point out what I'm doing wrong as if I use the same url in chrome I'm getting the json response but can''t seem to get the response via code.

Answer 1

A response of 403 means you either submitted credentials improperly or you submitted invalid credentials. So, there seem to be two obvious places that could be causing your issue here.

Firstly, are you properly setting your login and key into the URL at the substitution points?

Secondly, are you sure you are a valid and active login and key?
