这是我在node.js应用中发出的请求：
var https = require('https');
var options = {
host: 'maps.googleapis.com',
path: '/maps/api/geocode/json',
method: 'GET',
useQuerystring: true,
qs: 'address=' + "1600+Amphitheatre+Parkway,+Mountain+View,+CA" + "&key=[redacted in stack overflow post]"
};
var req = https.request(options, function(response) {
console.log(response);
//Uncomment the code below when you start getting valid responses
//response.on('data', function (chunk) {
// console.log('BODY: ' + chunk);
//});
});
console.log(req);
req.end();
但是响应回来了，statusCode：400，statusMessage：＆＃39; Bad Request＆＃39;。完整的回复可以在下面找到。
我在请求或响应中都没有看到我的查询字符串，这对我来说似乎很重要。我试过从选项中删除useQuerystring: true,，这似乎没有效果。我也试过添加www。在maps.googleapis.com前面，我知道它不会工作并确认。
我正在向Postman发出一个成功的请求，如下所示：
GET https://maps.googleapis.com/maps/api/geocode/json?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA&key=[redacted in stack overflow post]
如何使用https模块发出在Node中获得成功响应的请求？

注意：我已阅读Keep Getting Bad Request from HTTP.request in Node.js，这不是我的问题。我特别不应该包括www。在maps.googleapis.com
前面对于那些稍后阅读此内容的人，一旦您收到了良好的回复，您可能需要阅读：Where is body in a nodejs http.get response?
答案 0 :(得分：1)
您可以尝试在网址中指定queryString：path:'/maps/api/geocode/json' + '?' + <QueryString>
Alernatively，您可以考虑使用'requestify'模块。它可以通过' npm '进行安装。
源代码可在以下位置找到： - https://github.com/ranm8/requestify
因此，您的代码看起来像： -
var requestify = require('requestify');
requestify.get('https://maps.googleapis.com/maps/api/geocode/json?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA&key=<API_KEY>').then(function(response) {
// Get the response body
response.getBody();
});
IMP ：请记住在URL中替换您自己的API_KEY而不使用尖括号。
希望这会有所帮助.. :)
