本文介绍了一种常见的ReactNative开发中遇到的跨域调试问题，并提供了具体的解决步骤。当开发者尝试通过浏览器访问ReactNative应用时，可能会遇到因请求头缺少'Access-Control-Allow-Origin'字段而引发的跨域访问限制错误。文章详细解释了错误原因并给出了修改浏览器地址来解决问题的方法。

React Native调试时报如下错误

Failed to load http://localhost:8081/index.delta?platform=android&dev=true&minify=false: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://192.168.1.115:8081' is therefore not allowed access. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
