AngularJS unexpected token in fromJson()
提问by cutmancometh
The following line of code:
以下代码行：
var sid = $cookieStore.get('PHPSESSID');
is throwing this error:
正在抛出这个错误：
SyntaxError: Unexpected token m

So, I put a breakpoint at angular.js at line 779. The code there is:
所以，我在 angular.js 的第 779 行设置了一个断点。代码如下：
777 function fromJson(json) {
778 return isString(json)
779 ? JSON.parse(json)
780 : json;
781 }
The value of jsonas passed into JSON.parse()is "mnp801fap6kor50trgv4cgk7m2".
值json作为传递到JSON.parse()是“mnp801fap6kor50trgv4cgk7m2”。
I also noticed that other things getting passed into that method usually have two quotes around them, like ""userName"" for example.
我还注意到传递给该方法的其他内容通常有两个引号，例如“"userName""。
Please help. I'm banging my head against this for a couple hours.
请帮忙。几个小时以来，我一直在努力解决这个问题。
Or, if someone knows a better way to get the php session id out of the cookies using Angular, that would be great, too. (Yes, I could do it using jQuery or bare-metal JS, but I'd prefer to keep using Angular).
或者，如果有人知道使用 Angular 从 cookie 中获取 php 会话 ID 的更好方法，那也太棒了。（是的，我可以使用 jQuery 或裸机 JS 来完成，但我更愿意继续使用 Angular）。
Thanks in advance!!!
提前致谢！！！

It doesn't appear that $cookieStoreis meant to read cookies that weren't created by $cookieStore. From the comments:
它似乎不是$cookieStore为了读取不是由$cookieStore. 来自评论：
* @description
* Provides a key-value (string-object) storage, that is backed by session cookies.
* Objects put or retrieved from this storage are automatically serialized or
* deserialized by angular's toJson/fromJson.
The automatically serialized or deserializedis the important part. I was able to reproduce your problem here: http://jsfiddle.net/xtmrC/
这automatically serialized or deserialized是重要的部分。我能够在这里重现您的问题：http: //jsfiddle.net/xtmrC/
You probably want to use $cookiesinstead, like so: http://jsfiddle.net/MXTY4/9/
你可能想$cookies改用，像这样：http: //jsfiddle.net/MXTY4/9/
angular.module('myApp', ['ngCookies']);
function CookieCtrl($scope, $cookies) {
console.log('haha', $cookies.PHPSESSID);
}

Or you can simply wrap the $cookieStorage in a function and return a value or an empty string.
或者您可以简单地将 $cookieStorage 包装在一个函数中并返回一个值或一个空字符串。
var sid = getPHPSESSID();
function getPHPSESSID() {
return $cookieStore.get('PHPSESSID') || '';
}
In that case you'll use the angular service with it's pros and if you don't put the key-value pair in cookies, you'll get the empty string in result
在这种情况下，您将使用具有优点的 angular 服务，如果您不将键值对放在 cookie 中，您将获得空字符串结果
