springboot 实现跨域访问 无需使用jsonp

在springboot的拦截器中添加respone的头信息即可

@override
  public boolean prehandle(httpservletrequest request, httpservletresponse response, object handler)
      throws exception {
    //string origin = (string) request.getremotehost()+":"+request.getremoteport();
    response.addheader("access-control-allow-origin", "*");
    //system.out.println("access-control-allow-origin");
    response.addheader("access-control-allow-methods", "post, get, options, delete");
    //system.out.println("access-control-allow-methods");
    response.addheader("access-control-max-age", "3600");
    //system.out.println("access-control-max-age");
    response.addheader("access-control-allow-headers", "x-requested-with,authorization");
    //system.out.println("access-control-allow-headers");
    response.addheader("access-control-allow-credentials","true");
    //system.out.println("access-control-allow-credentials");
    string api_key = request.getparameter("api_key");
    string api_secret = request.getparameter("api_secret");
;
      if (check(api_key,api_secret)){
        return true;
      }
      response.senderror(400,"api_key or api_secret are error");
      return false;
  }
@configuration
public class mywebmvcconfigurer implements webmvcconfigurer {
  @bean
  apiintercepter apiintercepter() {
    return new apiintercepter();
  }
  @override
  public void addinterceptors(interceptorregistry registry) {
    // 添加一个拦截器,连接以/v1为前缀的 url路径
    registry.addinterceptor(loginintercepter()).addpathpatterns("/admin/**");
    registry.addinterceptor(apiintercepter()).addpathpatterns("/v1/**");
  }
}

总结

以上所述是小编给大家介绍的springboot 实现跨域访问无需使用jsonp的实现代码,希望对大家有所帮助
