You said mode: 'no-cors'
which tells fetch
to silently ignore anything which requires CORS permission.你说
mode: 'no-cors'
告诉fetch
默默地忽略任何需要 CORS 权限的东西。
Setting the Content-Type
to application/json
requires CORS permission so your request is sent with Content-Type: text/plain
instead.将
Content-Type
设置为application/json
需要 CORS 权限,因此您的请求是使用Content-Type: text/plain
发送的。
This doesn't trigger the JSON body parser.这不会触发 JSON 正文解析器。
mode: 'no-cors'
.mode: 'no-cors'
。
