fetch SyntaxError: Unexpected end of inputat eval (eval at <anonymous> (dist.js......

使用fetch时，报错

前端使用fetch()时，报错如下：

SyntaxError: Unexpected end of input at eval (eval at <anonymous> (http://localhost:8280/dist/dist.js?v=@VERSION@:2695:2), <anonymous>:670:29)

并且打印response显示status是0

错误原因 及 解决方法

我在响应头（header）里加了跨域请求的配置：mode: ‘no-cors’，去掉就好了。 参考：https://stackoverflow.com/questions/32837916/response-status-0-using-fetch-polyfill-with-mode-no-cors

stackoverflow上给出的解释是： no-cors mode is only to CDN content, such as scripts, CSS and image, you cannot be used for getting data，response.status = 0 is right behavior
