本文介绍了ASP.NET Core 2.2 Kubernetes Inress：未找到自定义路径的静态内容的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有以下ingress.yml：
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: ingress
namespace: default
annotations:
kubernetes.io/ingress.class: "nginx"
nginx.ingress.kubernetes.io/ssl-redirect: "false"
nginx.ingress.kubernetes.io/rewrite-target: /$2
labels:
app: ingress
spec:
rules:
- host:
http:
paths:
- path: /apistarter(/|$)(.*)
backend:
serviceName: svc-aspnetapistarter
servicePort: 5000
- path: //apistarter(/|$)(.*)
backend:
serviceName: svc-aspnetapistarter
servicePort: 5000
部署ASP.NET Core2.2API应用程序并导航到http://localhost/apistarter/后，浏览器调试器控制台在加载静态内容和Java脚本时显示错误。此外，导航到http://localhost/apistarter/swagger/index.html会导致
Fetch error Not Found /swagger/v2/swagger.json
推荐答案
按照以下步骤运行代码：
- 入口：从ingress.yml移除URL重写
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: ingress
namespace: default
annotations:
kubernetes.io/ingress.class: "nginx"
nginx.ingress.kubernetes.io/ssl-redirect: "false"
labels:
app: ingress
spec:
rules:
- host:
http:
paths:
- path: /apistarter # <---
backend:
serviceName: svc-aspnetapistarter
servicePort: 5000
- 部署：将环境变量与ingress.yml中的路径基一起传递
apiVersion: apps/v1
kind: Deployment
# ..
spec:
# ..
template:
# ..
spec:
# ..
containers:
- name: test01
image: test.io/test:dev
# ...
env:
# define custom Path Base (it should be the same as 'path' in Ingress-service)
- name: API_PATH_BASE # <---
value: "apistarter"
- 程序：启用Program.cs中的环境参数加载
var builder = new WebHostBuilder()
.UseContentRoot(Directory.GetCurrentDirectory())
// ..
.ConfigureAppConfiguration((hostingContext, config) =>
{
// ..
config.AddEnvironmentVariables(); // <---
// ..
})
// ..
- 启动：在Startup.cs中应用UsePath BaseMiddleware
public class Startup
{
public Startup(IConfiguration configuration)
{
_configuration = configuration;
}
private readonly IConfiguration _configuration;
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
var pathBase = _configuration["API_PATH_BASE"]; // <---
if (!string.IsNullOrWhiteSpace(pathBase))
{
app.UsePathBase($"/{pathBase.TrimStart('/')}");
}
app.UseStaticFiles(); // <-- StaticFilesMiddleware must follow UsePathBaseMiddleware
// ..
app.UseMvc();
}
// ..
}
