Question

以下代码行：

var sid = $cookieStore.get('PHPSESSID');

抛出此错误：

SyntaxError: Unexpected token m
at Object.parse (native)

所以，我在779行的angular.js处放了一个断点。那里的代码是：

777    function fromJson(json) {
778        return isString(json)
779            ? JSON.parse(json)
780            : json;
781    }

传递到json的{{1}}的值是“mnp801fap6kor50trgv4cgk7m2”。

我还注意到，传递给该方法的其他内容通常会有两个引号，例如“”userName“”。

请帮忙。我几个小时就撞到了这个头。

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，那也会很棒。（是的，我可以使用jQuery或裸机JS来做，但我更喜欢继续使用Angular）。

提前致谢!!!

$cookieStore似乎不是为了读取$cookieStore未创建的Cookie。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.

automatically serialized or deserialized是重要的一部分。我能够在这里重现您的问题：http://jsfiddle.net/xtmrC/

您可能希望使用$cookies，例如： 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.

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

fromJson（）中的AngularJS意外标记
