Question

我正在从android获取联系人列表，我想使用HTTP URL连接将其发送到服务器。但是每次，最后添加到jsonobject的数组都会以字符串双引号显示。内部包含jsonArray时，如何编码jsonobject？

     ArrayList<JSONObject> maps = new ArrayList<>();
     String result ="";
     try {

         for (int i = 0; i < contactDetails.size(); i++) {
             String FIRSTNAME =contactDetails.get(i).firstName;
             String LASTNAME =  contactDetails.get(i).lastName;
             String CONTACT = contactDetails.get(i).contactNumber;
             String EMAIL =  contactDetails.get(i).email;




            JSONObject contact = new JSONObject();

             contact.put("firstName",FIRSTNAME );
             contact.put("lastName",LASTNAME );
             contact.put("contactNumber",CONTACT );
             contact.put("email", EMAIL);

             maps.add(contact);
         }


     } catch (Exception e) {
         // TODO Auto-generated catch block
         e.printStackTrace();
     }
     JSONObject mainContact = new JSONObject();
     try {
         mainContact.put("token",token);
         mainContact.put("contact",maps.toString());
     } catch (JSONException e) {
         // TODO Auto-generated catch block
         e.printStackTrace();
     }


     return mainContact;
}

您必须使用GSON库才能轻松实现它

类似这样的东西

ArrayList<String> mArrayList = new ArrayList<String>();
    mArrayList.add("First");
    mArrayList.add("Second");
    mArrayList.add("Third");
    mArrayList.add("Fourtrh");
    mArrayList.add("Fifth");
    mArrayList.add("Sixth");
    Log.i("Raw ArrayList", mArrayList);

    GsonBuilder gsonBuilder = new GsonBuilder();    
    Gson gson = gsonBuilder.create();

    String JSONObject = gson.toJson(mArrayList);
    Log.i("Converted JSONObject",JSONObject);

    Gson prettyGson = new GsonBuilder().setPrettyPrinting().create();
    String prettyJson = prettyGson.toJson(mArrayList);

    Log.i("Pretty JSONObject",prettyJson);

在使用httpsurlconnection发送到服务器之前，如何在添加到jsonobject时对jsonArray进行编码
