Swagger用户界面在响应体中返回“无内容”，响应代码0

Question

我是Swagger UI的新成员。我在Json中使用swagger。当响应也是时，Json。当单击尝试出时，我看到一个正确的请求URL，但是Swagger UI在响应体中返回"no content"，响应代码E 215 0。

​

​

提到 API的URL并不是可以公开访问的，但是承载Swagger 的站点与承载的站点位于同一个网络中。

我看到了this堆栈溢出问题，但没有找到解决方案。

我的Swagger.Json文件：

请任何一个人帮忙。提前谢谢。

Answer 1

这应该是CORS的问题。您应该将Access-Control-Allow-Origin: *添加到响应头中。

请参阅：https://github.com/swagger-api/swagger-ui/blob/master/README.md#cors-support

Answer 2

这应该是CORS的问题。您应该在响应头中添加访问控制-允许-原产地：*。

在启动类中使用此代码

//全球cors政策

 app.UseCors(x => x
            .AllowAnyOrigin()
            .AllowAnyMethod()
            .AllowAnyHeader());
