从 JSON.parse 数组中获取数据

我陷入了这个问题，我正在调用一个 webService，它返回一个 json 响应。

现在我想从该响应中获取特定的值，但在互联网上搜索并努力挣扎后无法修复它。

这是我的代码：

var xhr = Titanium.Network.createHTTPClient({

onload : function(e) {
     Ti.API.info("Received text: " + this.responseText);
     alert('success');
     },
 // function called when an error occurs, including a timeout
 onerror : function(e) {
     Ti.API.debug(e.error);
     alert('error');
 },
 timeout : 5000
});

var data = {"data":"system.connect"};
xhr.open("POST","http://mytesturl.net/services/json");
xhr.setRequestHeader("Content-Type", "application/x-www-form-urlencoded; charset=utf-8");
xhr.send("method=system.connect");

响应是这样的：

{"#error":false,"#data":{"sessid":"c4likn6vg33hngbpmobisrsbpcjjmf39","user":{"uid":0,"hostname":"102.119.85.120","roles":{"1":"anonymous user"},"session":"","cache":0}},"#response_code":200}

我想从上面的响应中获取 sessid 值。什么是正确的做法？

I am stuck in this problem, I am calling a webService that returns me a json response.

now i want to fetch a particular value from that response but after searching on internet and struggling a lot couldn't fix it.

here is my code:

var xhr = Titanium.Network.createHTTPClient({

onload : function(e) {
     Ti.API.info("Received text: " + this.responseText);
     alert('success');
     },
 // function called when an error occurs, including a timeout
 onerror : function(e) {
     Ti.API.debug(e.error);
     alert('error');
 },
 timeout : 5000
});

var data = {"data":"system.connect"};
xhr.open("POST","http://mytesturl.net/services/json");
xhr.setRequestHeader("Content-Type", "application/x-www-form-urlencoded; charset=utf-8");
xhr.send("method=system.connect");

The response is like this:

{"#error":false,"#data":{"sessid":"c4likn6vg33hngbpmobisrsbpcjjmf39","user":{"uid":0,"hostname":"102.119.85.120","roles":{"1":"anonymous user"},"session":"","cache":0}},"#response_code":200}

from the above response I want to fetch the sessid value.
what is the right approach?

以下内容可以在 jsfiddle.net 上查看和测试。

// Given a string of JSON called responseText
var responseText = '{"#error":false,"#data":{"sessid":"c4likn6vg33hngbpmobisrsbpcjjmf39","user":{"uid":0,"hostname":"102.119.85.120","roles":{"1":"anonymous user"},"session":"","cache":0}},"#response_code":200}';

// You can parse it to an object using JSON.parse
var responseObj = JSON.parse(responseText);

// And then access the properties as with any object
console.log(responseObj ["#data"]["sessid"]);

The following can be viewed and tested on jsfiddle.net.

// Given a string of JSON called responseText
var responseText = '{"#error":false,"#data":{"sessid":"c4likn6vg33hngbpmobisrsbpcjjmf39","user":{"uid":0,"hostname":"102.119.85.120","roles":{"1":"anonymous user"},"session":"","cache":0}},"#response_code":200}';

// You can parse it to an object using JSON.parse
var responseObj = JSON.parse(responseText);

// And then access the properties as with any object
console.log(responseObj ["#data"]["sessid"]);
