Question

我正在尝试阅读以下json回复

using System;
using System.Collections.Generic;
using System.Web.UI.WebControls;
using System.Web.UI;

public partial class CheckboxTest : Page
{
    private bool m_PostBackWasEmailChange = false;


    protected override void OnLoad(EventArgs e)
    {
        base.OnLoad(e);
    }

    protected override void OnPreRenderComplete(EventArgs e)
    {
        base.OnPreRenderComplete(e);
        ItemPanel.Enabled = true;
    }

    protected override void OnLoadComplete(EventArgs e)
    {
        base.OnLoadComplete(e);

        if (!IsPostBack)
            SendEmail.Checked = true;
        else
        {
            if (m_PostBackWasEmailChange) BoxChange.Text = "Checkbox was turned " + (SendEmail.Checked ? "on" : "off");
        }
    }

    protected override void OnSaveStateComplete(EventArgs e)
    {
        base.OnSaveStateComplete(e);
    }

    protected void OnSendEmailChanged(object sender, EventArgs e)
    {
        m_PostBackWasEmailChange = true;
    }
}

我需要一组＆＃34; apiNames＆＃34;。下面是关于我如何阅读json的课程

{
"title": "Flipkart Affiliate API Directory",
"description": "This directory contains information about all the affiliate       API's and their versions",
"apiGroups": {
"affiliate": {
    "name": "affiliate",
    "apiListings": {
        "bags_wallets_belts": {
            "availableVariants": {
                "v0.1.0": {
                    "resourceName": "bags_wallets_belts",
                    "get": "https://affiliate-api.flipkart.net/affiliate/feeds/youraffiliateid/category/v1:reh.json?expiresAt=1420910131274&sig=7db02590dfaea9a22f88c869d8035d05",
                    "post": null,
                    "put": null,
                    "delete": null
                }
            },
            "apiName": "bags_wallets_belts"
        },
        "washing_machine": {
            "availableVariants": {
                "v0.1.0": {
                    "resourceName": "washing_machine",
                    "get": "https://affiliate-api.flipkart.net/affiliate/feeds/youraffiliateid/category/v1:j9e-abm-8qx.json?expiresAt=1420910131275&sig=7c48abab9d35ae77fff3d998e1a2efdc",
                    "post": null,
                    "put": null,
                    "delete": null
                }
            },
            "apiName": "washing_machine"
        },
    }
 }
}

运行程序后，我得到了jsonArray＆＃34; apiGroups＆＃34;。但在那之后，没有任何反应。有人可以帮我解决这个问题吗？

Answer 1

试试这个：

JSONObject groupObject = jsonObject.getJSONObject("apiGroups");

String apiName =groupObject.getJSONObject("affiliate").getJSONObject("apiListings").getJSONObject("bags_wallets_belts").getString("apiName");

更具体地说明apiListings下的所有对象：

JSONObject apiListingObject = jsonObject.getJSONObject("apiGroups").getJSONObject("affiliate").getJSONObject("apiListings");
JSONObject obj4=null;
       //Getting all the keys inside json object with key- pages
          Iterator<String> keys= apiListingObject.keys();
          while (keys.hasNext()) 
         {
               String keyValue = (String)keys.next();
               obj4 = apiListingObject.getJSONObject(keyValue);
               //getting string values with keys- apiName
               String pageid = obj4.getString("apiName");           
         }

JsonResponse无法正常工作
