“傲慢编辑器”：找不到错误服务器或发生错误

Question

我在Swagger工具上比较新。我试着用swagger编辑器测试我的Restfull应用程序。我使用基本身份验证来访问web服务。

在 Swagger -UI中，预览看起来是正确的，即内容类型：application/json和json在body.But中，当我从Swagger编辑器发送请求到服务器时，我得到了一个错误。

ERROR Server not found or an error occurred

请帮帮我。

提前谢谢。

Answer 1

我找到解决办法了。

它的CORS问题。我的浏览器阻塞了cors请求。我安装了一个将Access-Control-Allow-Origin添加到传出请求的Chrome扩展。

Answer 2

确保您的服务器正在运行。

如果您安装了swagger，您可以

swagger project start

Answer 3

我有个小问题

这是CORS，但是：

在nodeJS中，我设置了：

app.use(function(req, res, next) {
  res.header("Access-Control-Allow-Origin", "*");
  res.header('Access-Control-Allow-Headers', 'Origin, X-Requested-With, Content-Type, Accept, Authorization');
  res.header('Access-Control-Allow-Methods', 'GET, POST, PUT, UPDATE, DELETE, OPTIONS')
  res.header("Content-Type", "application/json");
  next();
});

但是，只有在请求未经授权(api-key)的情况下才有帮助。要使它发挥作用，我必须改变和使用：

const cors = require('cors');
app.use(cors());

希望能帮上忙
