Swagger 编辑器：找不到错误服务器或发生错误

Question

我是 Swagger 工具的新手。我尝试使用 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 Content-Type: application/json 并且 json 在body.But 当我从 Swagger 编辑器向服务器发送 GET 请求时，出现错误。

ERROR Server not found or an error occurred

请帮帮我

提前致谢。

Answer 1

确保您有服务器运行。

如果你安装了swagger，你可以做

swagger project start

Answer 2

我得到了解决方案。

它的 CORS 问题。我的浏览器阻止了 cors 请求。我已经安装了一个 Chrome 扩展程序，它将 Access-Control-Allow-Origin 添加到传出请求中。

Answer 3

我遇到了类似的问题

这是 CORS，但是：

我在 nodeJS 中设置了：

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();
});

但它仅在请求未经授权时有用（api-key）。为了让它工作，我必须改变并使用：

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