shi*_*rma 10 javascript node.js express amazon-cloudfront restapi
我只是想在 nodejs 中使用 Cowin Setu API（印度）发出 covid 疫苗警报。但是我遇到了一些奇怪的事情，每当我点击获取请求时，我都会收到来自 cloudfront 的 403 响应代码说“请求已阻止”，但邮递员和浏览器也是如此。请帮助我
收到此错误：-

app.get("/", function(req, res) {

app.get("/test", function(req, res, next) {

month: "2-digit",
day: "2-digit"
};
var date = String(d.toLocaleDateString("en", options));
date = date.replace(/\//g, "-");
console.log(date);
const URL =
"https://cdn-api.co-vin.in/api/v2/appointment/sessions/public/findByPinpincode=110088&date=13-05-2021";
var options = {
url: URL,
method: 'GET',
headers: {
'Accept-Encoding': 'gzip, deflate',
'Accept-Language': 'en-GB,en;q=0.8,en-US;q=0.6,hu;q=0.4',
'Cache-Control': 'max-age=0',

};
request(options,function(err,res,body){
let json = body;
console.log(json);
});
const txt = "Finding vaccine centres for you....";
//tg.sendMessage(process.env.GROUP_ID, txt);
res.send(txt);
});
// Finally, start our server
app.listen(process.env.PORT, function() {
console.log("Covid app listening on port 3000!");
});
我希望这个问题会解决
谢谢

我user-agent在请求中添加了一个标头，以便 API 能够识别出我的请求来自浏览器，而不是来自脚本。
headers = {
'user-agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36',
}
url = "https://cdn-api.co-vin.in/api/v2/appointment/sessions/public/calendarByDistrict?district_id=303&date="+date
response = requests.get(url, headers=headers)

使用以下
var options = {
url: URL,
method: 'GET',
headers: {
Host: 'cdn-api.co-vin.in',
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/90.0.4430.93 Safari/537.36'
}
};
