just use the core httpsmodule with the https.requestfunction. Example for a POSTrequest (GETwould be similar):
只需使用带有https.request函数的核心https模块即可。POST请求示例（GET类似）：
var https = require('https');
var options = {
host: 'www.google.com',
port: 443,
path: '/upload',
method: 'POST'
};
var req = https.request(options, function(res) {
console.log('STATUS: ' + res.statusCode);
console.log('HEADERS: ' + JSON.stringify(res.headers));
res.setEncoding('utf8');
res.on('data', function (chunk) {
console.log('BODY: ' + chunk);
});
});
req.on('error', function(e) {
console.log('problem with request: ' + e.message);
});
// write data to request body
req.write('data\n');
req.write('data\n');
req.end();

Note if you are using https.requestdo not directly use the body from res.on('data',... This will fail if you have a large data coming in chunks. So you need to concatenate all the data and then process the response in res.on('end'. Example -
请注意，如果您正在使用，https.request请不要直接使用来自 res.on('data',... 如果您有大量数据以块形式出现，这将失败。因此，您需要连接所有数据，然后处理res.on('end'. 例子 -
var options = {
hostname: "www.google.com",
port: 443,
path: "/upload",
method: 'POST',
headers: {
'Content-Type': 'application/json',
'Content-Length': Buffer.byteLength(post_data)
}
};
//change to http for local testing
var req = https.request(options, function (res) {
res.setEncoding('utf8');
var body = '';
res.on('data', function (chunk) {
body = body + chunk;
});
res.on('end',function(){
console.log("Body :" + body);
if (res.statusCode != 200) {
callback("Api call failed with response code " + res.statusCode);
} else {
callback(null);
}
});
});
req.on('error', function (e) {
console.log("Error : " + e.message);
callback(e);
});
// write data to request body
req.write(post_data);
req.end();

Using the request module solved the issue.
使用请求模块解决了这个问题。
// Include the request library for Node.js
var request = require('request');
// Basic Authentication credentials
var username = "vinod";
var password = "12345";
var authenticationHeader = "Basic " + new Buffer(username + ":" + password).toString("base64");
request(
{
url : "https://133-70-97-54-43.sample.com/feedSample/Query_Status_View/Query_Status/Output1?STATUS=Joined%20school",
headers : { "Authorization" : authenticationHeader }
},
function (error, response, body) {
console.log(body); } );
