Javascript 将JS对象提取为JSON

上面的URL包含这样一个对象

我想将其解压缩并以JSON格式打印到标准输出。有人能给我看一下实现这个目标的完整代码（python或nodejs）吗

您可以尝试使用regex获取实际的JavaScript对象。但是，如注释中所述，您需要首先执行代码，这可能会很危险

//NodeJS
常量请求=要求（“请求”）；
请求（“https://www.genenames.org/js/custom-downloads-bf.js“，（错误、正文、响应）=>{
const MatchedResponse=body.match（/{C.*？}；/gm）[0]；//将对象从“{C”匹配到“}；”
让我们来回应；
评估（“JSONResponse=“+MatchedResponse”）
log（JSON.stringify（JSONResponse））；
});

如果您担心对象中嵌入了恶意代码，您应该在执行之前创建一个函数来验证代码。

我可能会美化.js（例如使用）：

然后运行它：

sed -n $'/^[ \t]*CHROMOSOMES/,/^[ \t]*};/p' |
  sed -e '1s/^/{/' -e '$s/;//'

唯一可靠的方法是实际执行该代码。如果您不信任来源，则这可能是危险的。虽然我想你可以用沙箱来装…怎么装呢？有没有办法在nodejs程序中创建一个沙盒来运行代码？有，有几个模块可以实现这一点。这里有一个问题：你介意在输入custom-downloads-bf.js文件上编写一个脚本吗？但是这个正则表达式似乎不太可靠。如果从“{C”到“}”还有其他对象呢？
