所以我想创建一个网站，发送一封信给当地的国会议员。该网站主要由一个表单组成，在点击“提交”后，应该让代表联系使用Google Civic Info API的代表。我对HTTP通信很陌生，所以我不确定为什么，当试图使用GET时，我得到了403错误。找不到如何正确使用API
我甚至不知道我是否正确使用API。这里的目标是提交一个地址（以及其他信息），将这些数据发送给API，并根据用户提交的信息返回一位议员。

我的代码：

的Javascript：
function getData(){
var xhr = new XMLHttpRequest()
xhr.open("GET", "https://www.googleapis.com/civicinfo/v2/representatives/", false);
xhr.send(null);
console.log(xhr.status);
console.log(xhr.statusText);
}
