我正在尝试从 ajax GET/POST 访问托管在控制台应用程序上的 REST 服务。由于两个应用程序将使用不同的端口，我配置了 REST 服务来处理跨源请求。我已经尝试了所有可用的解决方案，但我仍然无法从 ajax 访问该服务并收到 405。
我正在分享由 http 分析器捕获的原始请求-响应流。

REST 服务配置基于http://enable-cors.org/server_wcf.html和 http://www.khalidabuhakmeh.com/rest-http-verbs-and-iis-express
最佳答案
这不是有效的 HTTP GET 请求:
Access-Control-Request-Method: GET
Access-Control-Request-Headers: access-control-allow-origin, access-control-allow-methods
Accept-Encoding: gzip, deflate
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko
Host: bhawesh-pc:8000
DNT: 1
Connection: Keep-Alive
Cache-Control: no-cache
Content-Length: 0
GET 请求的第一行应该是:
GET /wanted_resource HTTP/1.1
因此，如果服务器查看 header 开头的请求方法，它会看到:
访问ss-Control-...
并将返回一个 405 不允许的方法。
此外，使用GET，不需要Content-Length header 。最好删除该行。
