Question

此http请求位于gulpfile中。我收到错误消息：

problem with request: getaddrinfo ENOTFOUND https://service.javascriptobfuscator.com/HttpApi.ashx https://service.javascriptobfuscator.com/HttpApi.ashx:80

请求

gulp.task("obfuscate", "Obfuscate this", function() {
    console.log("obfuscate this!");

    var proj = {
        "APIKey": "hidden",
        "APIPwd": "hidden",
        "Name": "Sample1",
        "ReplaceNames": true,
        "MoveStrings": true,
        "EncodeStrings": true,
        "items": [
            {
                "FileName": "test0.js",
                "FileCode": "function hello(x,y){var z=11;return x+y+z;}"
            },
            {
                "FileName": "test1.js",
                "FileCode": "var strs=['aaaa','bbbb','cccc','dddd','eeee','abcdefghijklmnopqrstuvwxyz0123456789']"
            }
        ]
    };

    var options = {
        hostname: 'https://service.javascriptobfuscator.com/HttpApi.ashx',
        path: '',
        method: 'POST',
        headers: {
            'Content-Type': 'text/json'
        }
    };

    var req = http.request(options, function(res) {
        console.log('Status: ' + res.statusCode);
        //console.log('Headers: ' + JSON.stringify(res.headers));
        res.setEncoding('utf8');
        res.on('data', function (body) {
            //console.log('Body: ' + body);
        });
    });

    req.on('error', function(e) {
        console.log('problem with request: ' + e.message);
    });

    //console.log(JSON.stringify(proj));

    // write data to request body
    req.write(JSON.stringify(proj));
    req.end();
});

有什么问题？

Answer 1

hostname应该只是托管主机的名称，你在那里放了一个完整的URL。

将该值拆分为protocol，hostname和path。即：

var options = {
    protocol: 'https:'
    hostname: 'service.javascriptobfuscator.com',
    path: '/HttpApi.ashx',
    method: 'POST',
    headers: {
        'Content-Type': 'text/json'
    }
};

解释错误消息的秘诀是要意识到“getaddrinfo”是一种用于进行DNS查找的方法（即它将主机名转换为IP地址）。如果该方法抱怨“https://service.javascriptobfuscator.com/HttpApi.ashx”，则必须传递错误的值，因为这不仅仅是主机名。

Answer 2

当我将https://作为主机名的一部分删除时，它有效。

以下编辑修复了问题：

var options = {
    hostname: 'service.javascriptobfuscator.com',
    path: '/HttpApi.ashx',
    method: 'POST',
    headers: {
        'Content-Type': 'text/json'
    }
};
