nodejs请求忽略HTTPS

Question

节点请求模块忽略代理并在请求任何HTTPS地址时公开服务器IP。请求HTTP地址时，一切正常。怎么了？

    const request = require('request'),
    zlib = require('zlib'),
    fs = require('fs')
var cb = 1
request.get({
    timeout: 45000,
    gzip: true,
    pool: false,
    followRedirect: false,
    headers: {},
    url: 'https://api.ipify.org?format=json',
    proxy: '111.64.234.5:31218'
}).on('error', function (err) {
    console.log(err + 'ERRRRRRRORRRRRR')
}).on('response', function (res) {
    var chunks = [];
    res.on('data', function (chunk) {
        chunks.push(chunk);
    });
    res.on('end', function () {
        var buffer = Buffer.concat(chunks);
        var encoding = res.headers['content-encoding'];
        if (cb) {
            cb = 0
            if (encoding == 'gzip') {
                zlib.gunzip(buffer, function (err, decoded) {
                    console.log(decoded.toString())
                });
            } else if (encoding == 'deflate') {
                zlib.inflateRaw(buffer, function (err, decoded) { //inflate instead ???
                    console.log(decoded.toString())
                })
            } else {
                console.log(buffer.toString())
            }
        }
    });
})

您可以尝试任何IP：PORT作为代理。有什么想法吗？
