仅在Firefox中出现JSON语法错误 [英] JSON syntax error in firefox only

问题描述

使用$.parseJSON()时，我在FireFox中遇到语法错误.相同的代码可在Chrome/Chromium和Safari上正常工作.

Im getting a syntax error in FireFox when using $.parseJSON(). The same code works properly on Chrome/Chromium, and Safari.

我调用此函数以获取随机生成的令牌进行设置.

I call this function to get a random generated token to set.

function getToken() {
    var url = "/csrf_token_generate";
    $.ajax({
        url: url,
        method: "GET"
    }).done(function(data) {
        console.log(data); // Logs the data from the call
        var json = $.parseJSON(data); // Where the error occurs
        token = json.token;
        console.log(token);
    });
}

URL /csrf_token_genrate返回类似于{"token":"$2y$10$jcr.P3FNqeji6RqD93LnxeIKs9gYNiPj7cboahz8RCCSgKw7VOfhi"}

The URL /csrf_token_genrate returns a JSON object similar to {"token":"$2y$10$jcr.P3FNqeji6RqD93LnxeIKs9gYNiPj7cboahz8RCCSgKw7VOfhi"}

在URL中，我将Content-Type设置为application/json，这在其他所有浏览器中都可以使用.

In the URL, I am setting the Content-Type to application/json which works in every other browser.

我得到的错误是这个

SyntaxError: JSON.parse: unexpected character at line 1 column 2 of the JSON data
n.parseJSON()                jquery.min.js:4
getToken/<()                 wheel.bak.js:94
n.Callbacks/j()              jquery.min.js:2
n.Callbacks/k.fireWith()     jquery.min.js:2
x()                          jquery.min.js:4
.send/b/<()                  jquery.min.js:4

正在被console.log()编辑的对象是这个Object { token: "$2y$10$60vxSZiVqushBLVHSR5jPO6MquD4…" }

The object that is being console.log()'ed is this Object { token: "$2y$10$60vxSZiVqushBLVHSR5jPO6MquD4…" }

我似乎无法追查为什么它仅在FireFox中不起作用，而在其他浏览器中却可以正常工作.

I just can't seem to track down why it won't work in only FireFox, but works fine in other browsers.

更新1

我发现firefox试图解析一个已经解析的对象，所以我更改了代码，使其保持不变

I figured out that firefox was trying to parse an already parsed object, so I changed the code to be along this

function getToken() {
    var url = "/csrf_token_generate";
    $.ajax({
        url: url,
        method: "GET"
    }).done(function(data) {
        var json = data;
        token = json.token;
        console.log(token);
    });
}

现在可以在Firefox中使用，但不能在Chromium中使用.

Which now works in firefox, but not Chromium.

那该做什么呢?

推荐答案

我认为您应该检查Response Headers-> Content-Type以找到实际的Data Type. 兼容的代码应该像这样.

I think you should check the Response Headers -> Content-Type to find the actual Data Type. And the compatible code should like this.

# for chrome
if(typeof data === 'string') {

}
#for firefox
if(typeof data === 'object') {

}
