我使用的是chrome 53.0.2785.116 m(64位).

我在devtools上得到了以下标题.该问题标有"//"注释.内容类型真的不允许我们将它设置为application/json,我尝试了100种不同的方式.

import fetch from 'isomorphic-fetch';
const option = {
    method: 'POST',
    mode: 'no-cors',
    headers: {
      'Accept': 'application/json',
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({'aa':'bb'})
}
fetch('/books', opts)
.then(check401)
.then(check404)
.then(jsonParse)
.then(errorMessageParse);
