org.json.JSONException：JSONArray文本必须以'['at 1 [character 2 line 1]开头

Question

I have exception when I want to read JSON array from local address php. String in php looks like this:

[{"firstname":"ime1","lastname":"prezime1"},{"firstname":"ime2","lastname":"prezime2"},{"firstname":"ime3","lastname":"prezime3"}]

And my code for loading looks like this:

JSONArray jsonArray = new JSONArray("http://192.168.1.23/get_people.php");

Exceptoin is:

org.json.JSONException: A JSONArray text must start with '[' at 1 [character 2 line 1]

Answer 1

You have an exception because your application never calls your service url http://192.168.1.23/get_people.php . So, when you use new JSONArray("http://192.168.1.23/get_people.php") , the application tries to create a JSONArray using the string " http://192.168.1.23/get_people.php ", and not considering the return value of your ws.

There are many ways to consume a WS, you can look at restTemplate , cxf or other library.
