我正在尝试从
Angularjs客户端对我的API进行POST,我在另一个域中运行的服务器上进行了此配置:
app.use(function(req,res,next) { res.setHeader('Access-Control-Allow-Origin','*'); res.setHeader('Access-Control-Allow-Methods','GET,POST,PUT,OPTIONS,DETELE'); res.setHeader('Access-Control-Allow-Headers','*'); next(); });
发送到服务器的标头是:
OPTIONS /api/authenticate HTTP/1.1 Host: xxxx.herokuapp.com Connection: keep-alive Access-Control-Request-Method: POST Origin: http://127.0.0.1:5757 User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_5) AppleWebKit/537.36 (KHTML,like Gecko) Chrome/45.0.2454.93 Safari/537.36 Access-Control-Request-Headers: accept,content-type Accept: */* Referer: http://127.0.0.1:5757/login Accept-Encoding: gzip,deflate,sdch Accept-Language: en,es;q=0.8,gl;q=0.6,pt;q=0.4
响应标头是:
HTTP/1.1 403 Forbidden Server: Cowboy Connection: keep-alive X-Powered-By: Express Access-Control-Allow-Origin: * Access-Control-Allow-Methods: GET,DETELE Access-Control-Allow-Headers: X-Requested-With,content-type,Authorization Content-Type: application/json; charset=utf-8 Content-Length: 47 Etag: W/"2f-5f255986" Date: Sun,20 Sep 2015 19:26:56 GMT Via: 1.1 vegur
我在Chrome控制台中获得的是:
