Javascript 如何向google map api发送http请求

这是我在node.js应用程序中发出的请求：

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();

但响应返回的状态代码为：400，状态消息为：“错误请求”。下面是完整的答复

我在请求或响应中都没有看到我的查询字符串，这似乎与我有关。我尝试过删除useQuerystring：是的，从选项中删除，这似乎没有效果。我还试着在maps.googleapis.com前面添加www

我向邮递员提出了一个成功的请求，如下所示： 收到https://maps.googleapis.com/maps/api/geocode/json?address=1600+圆形剧场+公园道，+山景，+CA&key=[在堆栈溢出柱中编辑]

如何使用https模块在节点中发出请求以获得成功响应

这是console.logreq的输出：

这是console.logres的输出：

注：我读过，这不是我的问题。我特别不应该在maps.googleapis.com前面添加www

对于稍后阅读本文的读者，一旦收到良好的响应，您可能希望阅读以下内容：

您可以尝试在URL本身中指定查询字符串：路径：'/maps/api/geocode/json'+'？'+

注意，您可以考虑使用“请求”模块。它可以通过“npm”安装

源代码可在以下位置找到：-

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：记住在URL中替换您自己的API_键，不带尖括号

---

希望这有帮助：

谢谢你的提示。我应该指定我打算使用https模块，并希望避免另一种依赖关系。@Glen，请查看Chrome开发者控制台中的“网络”选项卡，并查看HTTP请求是在哪个URL发出的。另外，您可能在“path”字段的末尾缺少一个“？”。另外，您可以尝试在URL本身中指定查询字符串，即：-path:“/maps/api/geocode/json”+“？”+我正在从服务器进行调用，它不是客户端，所以我没有访问Chrome开发工具的权限。调整请求选项以将查询字符串包含在路径中会导致良好的响应状态。非常感谢。
