如何在javascript/nodejs中拆分包含n个串联的json字符串的字符串? [英] How can I split a string containing n concatenated json string in javascript/nodejs?

问题描述

假设我从套接字服务器(我无法控制)接收此字符串:

Let's say I receive this string from a socket server (which I cannot control):

{"data":{"time":"2016-08-08T15:13:19.605234Z","x":20,"y":30}}{"data":{"time":"2016-08-08T15:13:19.609522Z","x":30,"y":40}} 

我无法使用JSON.parse，因为它包含2个Json字符串，所以我如何拆分成

I cannot use JSON.parse since it contains 2 Json string so how can I split into

var jsonString1 = {"data":{"time":"2016-08-08T15:13:19.605234Z","x":20,"y":30}}

和

var jsonString2 = {"data":{"time":"2016-08-08T15:13:19.609522Z","x":30,"y":40}} 

注意:实际上我可能有1到n个Json字符串连接

Note: I may have 1 to n Json strings concatenated in fact

推荐答案

您可以这样做:

var data = '{"data":{"time":"2016-08-08T15:13:19.605234Z","x":20,"y":30}}{"data":{"time":"2016-08-08T15:13:19.609522Z","x":30,"y":40}}';

var sanitized = '[' + data.replace(/}{/g, '},{') + ']';
var res = JSON.parse(sanitized);

console.log(res);

但是，如果其中一个对象在字符串中包含}{模式，则此操作将失败.

However, this will fail if one of the objects contains the }{ pattern in a string.
