javascript - nodejs - 无法使用代理服务器拦截应用程序流量

Question

我想拦截和镜像来自应用程序的流量。我创建了一个简单的 nodejs cli 脚本，它将运行代理服务器。我需要打开目标应用程序蚂蚁然后拦截所有请求以将它们记录到控制台中。这是代码

const exec = require('child_process').execSync;
const http = require('http');

http.createServer( (clientReq, clientRes) => {
    console.log('requesting: ' + clientReq.url);

    const options = {
        hostname: clientReq.url,
        port: 80,
        path: clientReq.url,
        method: clientReq.method,
        headers: clientReq.headers
    }

    const proxy = http.request(options, (res) => {
        clientRes.writeHead(res.statusCode, res.headers);
        res.pipe(clientRes, {
            end: true
        });
    });

    clientReq.pipe(proxy, {
        end: true
    });

}).listen(3000);

发生的事情是，如果我尝试打开应用程序然后运行代理服务器，脚本会给我这个错误，如果我从控制台运行它，相同的命令将起作用

//command
exec('open /Users/dev/Applications/My\ applicationo.app --args --proxy-server=localhost:3000 --ignore-certificate-errors');
//error in console
The files /Users/dev/Applications/My and /Users/dev/Desktop/proxy-req/applicationo.app do not exist.
node:child_process:747
    throw err;
    ^

Error: Command failed: open /Users/dev/Applications/My applicationo.app --args --proxy-server=localhost:3000 --ignore-certificate-errors
The files /Users/dev/Applications/My and /Users/dev/Desktop/proxy-req/applicationo.app do not exist.

为了避免错误，execSync我尝试直接从终端运行命令，目标应用程序将正确打开，但是当应用程序尝试发出请求时，脚本将停止并记录此错误：

node:events:342
      throw er; // Unhandled 'error' event
      ^

}

如果我单击它记录的 url 工作正常。我不确定问题是否出在代码和请求选项配置上。如何将命令修复到脚本中，以便在执行脚本时直接打开应用程序以及如何修复有关请求的错误？
