事情板上请求的资源上没有'Access-Control-Allow-Origin'标头. angularjs [英] Thingsboard No 'Access-Control-Allow-Origin' header is present on the requested resource. angularjs

问题描述

我正在使用GET方法获取事物板Restfull Http Apis的数据，但是我们无法获取数据.

I am working on fetch data of thingsboard Restfull Http Apis using GET method, but we are not able to get fetch data.

Response to preflight request doesn't pass access control check:
No 'Access-Control-Allow-Origin' header is present on the requested resource. 
Origin 'http://localhost:8888' is therefore not allowed access.
The response had HTTP status code 401.

我们正在Angularjs平台上调用Thingsboard Apis.我们如何解决这个错误.

We are calling Thingsboard Apis on Angularjs platform. How we can Solve this error.

POST方法运行正常，但是在东西板上的GET方法上出现错误.

先谢谢了！
