Json中的解析函数 [英] Parse function inside Json

问题描述

由于函数JSON.stringify（），我有这个JSON：

I have this JSON as a result of the function JSON.stringify():

{"get":"function (f,g){'use strict';var h,i;if(i={},'string'==typeof f){if('object'==typeof g)for(h in g)i[h]=g[h];i.url=f}else if('object'==typeof f)for(h in f)i[h]=f[h];return i.type=i.type||d,i.oauthio={provider:a,tokens:b,request:c},e.http(i)}","post":"function (f,g){'use strict';var h,i;if(i={},'string'==typeof f){if('object'==typeof g)for(h in g)i[h]=g[h];i.url=f}else if('object'==typeof f)for(h in f)i[h]=f[h];return i.type=i.type||d,i.oauthio={provider:a,tokens:b,request:c},e.http(i)}"}

你怎么能看到那里是值内的函数。我想重建这个JavaScript对象，我的目标是删除risult中的引号以及值;因为在这种情况下，函数被识别为字符串。我想要这样的东西： {key：value}

How you can see there are functions inside values. I want to rebuild this JavaScript object, my goal is to remove the quotes in the risult but also the values; because functions, in this case, are recognized as string. I want something like this:{key : value}

现在我得到： { key：value}

推荐答案

快速回答：

以下函数将执行此操作：

The function bellow will do it:

function fix(obj){

    for (var property in obj) {
        if (obj.hasOwnProperty(property)) {
            obj[property] = eval("(" + obj[property] + ")");
        }
    }

}

如果 obj 有你的JSON解析对象，然后执行以下操作：

If obj has your JSON parsed object then just do the following:

fix(obj);
console.log(obj); // in case you want to see the change in the console

说明（如果您需要） ONE）：

如果在调用eval之前用括号'（）'括起字符串，你将能够获得javascript函数表达式。

You will be able to get the javascript function expression if you enclose the string with parentheses '()' before invoking eval.

所以实现所需结果的步骤是：

So the steps to achieve the desired result are:

1. 将函数表达式字符串括起来括号（参见脚注原因）


2. 调用eval函数来计算函数声明表达式


3. 将函数声明表达式赋值给同一属性包含字符串值

对于您给出的简单示例，您可以通过以下方式获得所需的结果：

For the simplistic example you gave, you can get the desired results by:

var obj = {"get":"function (f,g){'use strict';var h,i;if(i={},'string'==typeof f){if('object'==typeof g)for(h in g)i[h]=g

[h];i.url=f}else if('object'==typeof f)for(h in f)i[h]=f[h];return i.type=i.type||d,i.oauthio=

{provider:a,tokens:b,request:c},e.http(i)}","post":"function (f,g){'use strict';var h,i;if(i={},'string'==typeof f){if

('object'==typeof g)for(h in g)i[h]=g[h];i.url=f}else if('object'==typeof f)for(h in f)i[h]=f[h];return i.type=i.type||

d,i.oauthio={provider:a,tokens:b,request:c},e.http(i)}"};

obj.get = eval("(" + obj.get + ")");
obj.post = eval("(" + obj.post + ")");

您可以使用以下功能自动执行此操作：

You can automate that by using the following function:

function fix(obj){

    for (var property in obj) {
        if (obj.hasOwnProperty(property)) {
            obj[property] = eval("(" + obj[property] + ")");
        }
    }

}

你的最终代码应该是这样的：

Your final code should be something like:

function fix(obj){

        for (var property in obj) {
            if (obj.hasOwnProperty(property)) {
                obj[property] = eval("(" + obj[property] + ")");
            }
        }

    }


var obj = {"get":"function (f,g){'use strict';var h,i;if(i={},'string'==typeof f){if('object'==typeof g)for(h in g)i[h]=g

    [h];i.url=f}else if('object'==typeof f)for(h in f)i[h]=f[h];return i.type=i.type||d,i.oauthio=

    {provider:a,tokens:b,request:c},e.http(i)}","post":"function (f,g){'use strict';var h,i;if(i={},'string'==typeof f){if

    ('object'==typeof g)for(h in g)i[h]=g[h];i.url=f}else if('object'==typeof f)for(h in f)i[h]=f[h];return i.type=i.type||

    d,i.oauthio={provider:a,tokens:b,request:c},e.http(i)}"};

fix(obj);
