WEbAPI为身份验证请求提供端点:http:\ ...\token
应使用方法"POST"和Body like发送身份验证请求
"grant_type=password&username=name&password=mypassword"
这个WebAPI由Front-End使用,它是使用AngularJS编写的.有时在发送带有有效Body的"POST"请求之前,会发送一个没有Body的"OPTIONS"请求.结果,WebAPI返回以下错误:
Status: 400
{"error":"unsupported_grant_type"}
有没有可以在服务器端实现的解决方案？(在WebAPI中)
