javascript - 解析来自 3rd 方服务器的 json 时出现问题

Question

我有一个 Grease Monkey 脚本，它基本上从游戏中收集信息并将其发送到我的服务器以跟踪我们团队的进度。这涉及到我的 GM 脚本和游戏之间的大量 Ajax 请求，然后向服务器发送一个大的转储。在从游戏收集数据的过程中，似乎一个或多个请求结果的 JSON 格式不正确。我已将其打印到控制台，它似乎是一个字符串而不是一个对象。我尝试了一些快速的 JSON.parse(JSON.stringify(r)) 但这会引发 意外的数据结束 错误。经过一番研究，我提出了下面的函数来处理 Ajax 响应，但记录的“对象”仍然显示为字符串，并且仍然导致脚本的其余部分失败。

function(r){
    if(typeof r === 'object'){
        result = r;
    }else if(typeof r === 'string'){
        r.trim();
        if(r.charAt(0) == '"'){
            fNQ = r.indexOf('"') + 1;
            lNQ = r.lastIndexOf('"');
            r = r.substring(fNQ, lNQ);
            r = r.trim();
        }
        uW.console.log(r);
        result = r;
    }   
    if(!result){
        result = r;
    }
}

如何确保第 3 方的 Ajax 响应正确格式化为 JSON 以便供脚本的其余部分使用？

Answer 1

您尝试在再次字符串化后解析该字符串。删除多余的 JSON.stringify，否则最终会出现多余的引号。
