How to send json data in url as request parameters

问题:

I want to send json data in url as below .

editTest.jsp?details=374889331-{"aNumber":2}

How can I do this?

回答1:

URL encode your details parameter:

String otherParameter = "374889331-";    
String jsonString = "{\"aNumber\":2}";

String url = "editTest.jsp?details=" + URLEncoder.encode(otherParameter + jsonString, "UTF-8");

回答2:

you need to convert the JSON object to string

      JSONObject obj = new JSONObject();

      obj.put("name","foo");

      StringWriter out = new StringWriter();
      obj.writeJSONString(out);

      String jsonText = out.toString();//JSON object is converted to string

Now, you can pass this jsonText as parameter.

回答3:

Json2 can help. JSON.stringify(obj)

回答4:

We can use the help of Gson

String result =new Gson().toJson("your data");

NB: jar file needed for Gson
