Swagger编辑器：错误，未找到服务器或发生错误。

Question

我是Swagger工具的新手。我尝试使用Swagger编辑器测试我的Restful应用程序。我使用基本身份验证来访问Web服务。

在Swagger-UI中，预览看起来正确，即Content-Type: application/json，并且JSON位于正文中。但是当我从Swagger编辑器向服务器发送GET请求时，出现了错误。

ERROR Server not found or an error occurred

假设您的服务器响应了您配置的内容：http://127.0.0.1:8610/api/v1? - fehguy

Answer 1

我已经找到解决方法。 这是跨域资源共享（CORS）问题。我的浏览器正在阻止CORS请求。我安装了一个Chrome扩展程序，可以在发送的请求中添加Access-Control-Allow-Origin。

我已经下载了，但仍然无法允许请求。之后还需要做些什么吗？ - thisisdude

Answer 2

请确保您的服务器正在运行。

如果您已经安装了Swagger，可以执行以下操作：

swagger project start

Answer 3

我遇到了类似的问题

这是CORS，但是：

在nodeJS中我已经设置了：

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();
});

但仅在请求未经授权（api-key）时才有效。为使其正常工作，我必须进行更改并使用：

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

希望有帮助
