我有一个基于Sinatra的服务器,它为我正在处理的服务提供RESTful API。在我的开发机器上运行localhost:9393
。
同时,使用ember.js
进行用户身份验证的客户端应用程序(使用ember-auth
构建)在另一个端口上运行:localhost:9000
。
以前我在同一台主机上设置服务器和客户端:端口和返回的客户端应用程序作为静态文件。身份验证工作得很好。根据SignIn上的official docs,我在我提供的路由上获得了POST请求(/signin
)。但现在我收到 OPTIONS 请求,没有任何参数。
来自客户端的一些代码(客户端是通过Yeoman的ember-generator生成的):

您的REST API和客户端应用程序来自不同的来源;协议,主机和端口必须与same-origin policy相同。您的浏览器正在制作预检OPTIONS请求,以确定您的服务器是否允许来自您的客户端域的cross-origin resource sharing (CORS)。
要让CORS与Sinatra服务器一起使用,您可能需要查看rack-cors,这将允许您添加中间件以设置必需的访问控制标头。一旦设置正确,将在成功的OPTIONS请求之后发出预期的POST请求。
