Question

Android代碼：

OkHttpClient client = new OkHttpClient();
Request request = new 
Request.Builder().url("http://10.0.2.2/TEST/Latest/getBatsman.php?var="+var)
.build();


Response response = client.newCall(request).execute();
JSONObject jsonObject = new JSONObject(response.body().string());
JSONArray jsonArray = jsonObject.getJSONArray("batsman");

PHP代碼：

include('DBdetails.php');
global $conn;
$id = $_GET["var"];

$sql = "SELECT * FROM `all_players` where teamname='".$id."'";
$result = $conn->query($sql) ;
$temparray =  array();

while($row = $result->fetch_assoc())
{
$temparray[] = $row;
}
$tOutput = json_encode($temparray);
echo json_encode(array('batsman' => json_decode($tOutput) ));

例外情況：

W/System.err: org.json.JSONException: Value <br of type java.lang.String 
cannot be converted to JSONObject
W/System.err:     at org.json.JSON.typeMismatch(JSON.java:111)
W/System.err:     at org.json.JSONObject.<init>(JSONObject.java:160)
W/System.err:     at org.json.JSONObject.<init>(JSONObject.java:173)

JSON響應在瀏覽器中嘗試過，沒有html響應：

希望這段代碼對您有所幫助。

String post(String url, JSONObject login) {
    try {
        MediaType mediaType = MediaType.parse("application/json");
        RequestBody body = RequestBody.create(mediaType, login.toString());
        okhttp3.Request request = new okhttp3.Request.Builder()
                .url(url)
                .post(body)
                .addHeader("Authorization", "Bearer " + token)
                .build();

        okhttp3.Response response = client.newCall(request).execute();

        try {
            return response.body().string();
        } catch (IOException e) {
            e.printStackTrace();
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
    return "";
}

String response;

private class AsyncTaskRunner extends AsyncTask<String, String, String> {

    @Override
    protected void onPreExecute() {
    }

    @Override
    protected String doInBackground(String... params) {

        try {
            response = post(
                    insertUrl, jsonObject);
            Log.d("PUT JSON ARRAY___", jsonObject.toString());

        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }

    @Override
    protected void onPostExecute(String result) {
        Log.d("---OKHTTP---", response);
        try {
            JSONObject jobj = new JSONObject(response);
        } catch (JSONException e) {
            e.printStackTrace();
        }
    }
}
