如何从URL获取JSON作为字符串？

Question

I want to have an array with the value of json:

arr[ ] array = {"http://www.ip-api.com/json"};

when I print this array, how can I have json but not " http://www.ip-api.com/json " as a string?

Answer 1

Use a JSON generating library such as Jackson and have it serialize the data structure.

If you want to actually mean that you want to call the service at that URL then you need to use a suitable library for that...
