解决 asp.net core swagger nginx 代理服务器转发后,无法访问的问题 Swashbuckle
通过代理转发后,webapi的swagger无法访问,本质原因是代理后url路径发生变化导致swagger无法定位到json。
官方文档配置:
https://docs.microsoft.com/en-us/aspnet/core/tutorials/getting-started-with-swashbuckle
https://docs.microsoft.com/en-us/aspnet/core/host-and-deploy/linux-nginx?view=aspnetcore-3.1#use-a-reverse-proxy-server
Copyc.SwaggerEndpoint("/swagger/v1/swagger.json", "My API V1");
解决方法:
使用url相对路径
通过PreSerializeFilters设置根地址,并通过nginx的X-Forwarded-Prefix指定api名称
nginx配置:
Copyserver {
listen 5011;
server_name _;
location /api1/ {
proxy_pass http://192.168.56.1:5000/;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection keep-alive;
proxy_set_header Host $http_host; # 使用http_host而非host以满足带有端口号的情况
proxy_cache_bypass $http_upgrade;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Forwarded-Prefix api1; # api1用于传递路由名称
}
}
Swashbuckle 5.x 以前通过PreSerializeFilters设置BasePath的方案,5.x以后,设置OpenApiServer.Url属性
代码如下:
Copyapp.UseSwagger(c =>
{
c.PreSerializeFilters.Add((swagger, httpReq) =>
{
//根据访问地址,设置swagger服务路径
swagger.Servers = new List<OpenApiServer> { new OpenApiServer { Url = $"{httpReq.Scheme}://{httpReq.Host.Value}/{httpReq.Headers["X-Forwarded-Prefix"]}" } };
});
});
app.UseSwaggerUI(c =>
{
//使用相对路径
c.SwaggerEndpoint("v1/swagger.json", "My API V1");
});
