跨域請(qǐng)求服務(wù)器中的css文件，css請(qǐng)求成功，但是字體文件請(qǐng)求失敗

在開發(fā)者工具network中能夠看到字體文件的請(qǐng)求返回的是成功，但是console中輸出了以下內(nèi)容

Font from origin 'http://127.0.0.1:3000' has been blocked from loading by Cross-Origin Resource Sharing policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8080' is therefore not allowed access.

這是在服務(wù)中koa2-cors的配置

app.use(cors({
  origin: function (ctx) {
      return '*'
  },
  exposeHeaders: ['WWW-Authenticate', 'Server-Authorization'],
  maxAge: 5,
  credentials: true,
  allowMethods: ['GET', 'POST', 'DELETE'],
  allowHeaders: ['Content-Type', 'Authorization', 'Accept'],
})
