应用场景: 调某接口时, 获取json数据, 需要对数据进行解析 .

第一种: 只判断接口是否调用成功

{

"code":"10102000",

"data":"kkkkkkk"

}

//解析返回结果
JSONObject responseJsonObject = JSONObject.parseObject(response);
int code = responseJsonObject.getIntValue("code");
if (code == 10102000) {
    return 1;
}

第二种: 解析data中的数据

try {
    HttpResponse httpResponse = client.doAction(textScanRequest);  //获取结果
    if (httpResponse.isSuccess()) {
        JSONObject scrResponse = JSON.parseObject(new String(httpResponse.getHttpContent(), "UTF-8"));
        System.out.println(JSON.toJSONString(scrResponse, true));
        if (200 == scrResponse.getInteger("code")) {
            JSONArray taskResults = scrResponse.getJSONArray("data"); //获取数组
            for (Object taskResult : taskResults) { 
                if (200 == ((JSONObject) taskResult).getInteger("code")) {
                    JSONArray sceneResults = ((JSONObject) taskResult).getJSONArray("results");
                    for (Object sceneResult : sceneResults) { //遍历结果数组
                        String scene = ((JSONObject) sceneResult).getString("scene");
                        String suggestion = ((JSONObject) sceneResult).getString("suggestion");
                        String label = ((JSONObject) sceneResult).getString("label");
                        //根据scene和suggetion做相关处理
                        //do something
                        return label;
                    }
                } else {
                    System.out.println("task process fail:" + ((JSONObject) taskResult).getInteger("code"));
                }
            }
        } else {
            System.out.println("detect not success. code:" + scrResponse.getInteger("code"));
        }
    } else {
        System.out.println("response not success. status:" + httpResponse.getStatus());
    }
} 

第三种: 解析json中的数据

String response = HttpClientUtil.doGet(url, token, appCode);
//输出响应结果
JSONObject responseJsonObject = JSONObject.parseObject(response);
int code = responseJsonObject.getIntValue("code");
if (code == 10102000) {
    JSONArray jsonArray = responseJsonObject.getJSONObject("data").getJSONObject("linkmanList").getJSONArray("data"); //数组中的每条数据, 都是一个对象.
    for (int i = 0, n = jsonArray.size(); i < n; i++) {
        CompanyCarshipLinkman companyCarshipLinkman = jsonArray.getObject(i, CompanyCarshipLinkman.class);
        JSONObject jsonObject = jsonArray.getJSONObject(i); //当i = 0时, 获取第一个对象
        String linkmanId = jsonObject.getString("linkmanId");
        result.saveResult("linkmanId", linkmanId);
        linkmanList.add(companyCarshipLinkman);
    }
}
