我正在将以下消息从 Angular 服务发送到播放应用程序
public createUser(user:User):any{
console.log('contacting server at '+this.API_URL +this.ADD_USER_URL +" with user data ",user);
/*http.post returns an observable. The caller's code should subscribe to this observable */
return this.http.post(this.API_URL +this.ADD_USER_URL,user)
.map(response => { //handler if post's Observable is successful. map creates new User and returns Observable<User>.
console.log('response from backend service',response);
//return new User(response); //the constructor of User allows passing an object.
/*when the observable of http.post returns (produces) data (the response), the map function prints a message and returns that response*/
return response;
})
.catch(this.handleError); //error handler if Observable fails
}
我在 Play 的控制台上收到以下警告并禁止响应。

Play 的 CSRF 似乎不喜欢这条消息。我该如何解决这个问题?我在 Play 中读到,错误发生在
- 请求不是 GET、HEAD 或 Option - 在我的情况下是真的,我正在发送 POST 消息
- 请求具有 cookie 或 Authorization 标头。我没有明确地发送它们。Angular 默认发送它吗?
- CORS 过滤器未配置为信任请求的来源。- 我正在向 localhost:9000 发送请求。Play 不应该信任本地主机吗?
如何让 Play 接受我的消息?
