使用说明

+
+

1. 基础连接测试: 检查服务器是否可达，不需要 API Key

+

2. gRPC 连接测试: 需要有效的 API Key，测试完整的 gRPC 通信

+

3. Envoy 配置: 如果使用 Envoy 代理，请使用端口 8080 和禁用 TLS

+

4. 直连配置: 直接连接 Headscale 使用端口 50443 和启用 TLS

Envoy 配置生成器

+ +
+
+
+ + +
+
+ + +
+
+ + +
+
+ +
+
+

生成的 envoy.yaml 配置:

+ +
+
+ 
{generatedEnvoyConfig}
+
+
+ +
+

启动步骤:

+
    +
  1. 将上面的配置保存为 envoy.yaml
    2. +
  2. 运行: docker run -d -p {envoyConfig.proxyPort}:{envoyConfig.proxyPort} -v $(pwd)/envoy.yaml:/etc/envoy/envoy.yaml envoyproxy/envoy:v1.22-latest
    3. +
  3. 在设置中配置: 服务器地址 localhost, 端口 {envoyConfig.proxyPort}, TLS 禁用
    4. +
+
+
+
+ + +
+

其他配置方法

+ +
+
+

方法 2: 使用 Nginx 代理 (您当前的方案)

+
+ 
{`server {
+    listen 50443;
+    server_name localhost;
+
+    # CORS 配置
+    add_header 'Access-Control-Allow-Origin' '*' always;
+    add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS' always;
+    add_header 'Access-Control-Allow-Headers' 'DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range,Authorization,grpc-timeout,x-grpc-web' always;
+    add_header 'Access-Control-Expose-Headers' 'Content-Length,Content-Range,grpc-status,grpc-message' always;
+
+    # 处理 OPTIONS 预检请求
+    if ($request_method = 'OPTIONS') {
+        add_header 'Access-Control-Allow-Origin' '*';
+        add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
+        add_header 'Access-Control-Allow-Headers' 'DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range,Authorization,grpc-timeout,x-grpc-web';
+        add_header 'Access-Control-Max-Age' 1728000;
+        add_header 'Content-Type' 'text/plain; charset=utf-8';
+        add_header 'Content-Length' 0;
+        return 204;
+    }
+
+    location / {
+        grpc_pass grpc://${envoyConfig.headscaleServer}:${envoyConfig.headscalePort};
+        grpc_set_header Authorization $http_authorization;
+    }
+}`}
+
+

+ 使用您当前的 Nginx 配置，在设置中使用: localhost:50443 +

+
+ +
+

方法 3: 使用 grpcwebproxy

+
+ 
grpcwebproxy \\
+  --backend_addr={envoyConfig.headscaleServer}:{envoyConfig.headscalePort} \\
+  --run_tls_server=false \\
+  --allow_all_origins \\
+  --backend_tls_noverify
+
+

+ 然后在设置中使用: localhost:8000, TLS 禁用 +

+
+ +
+

常见问题

+
    +
  • Failed to fetch: 通常表示没有配置 gRPC-Web 代理
    • +
  • CORS 错误: 需要在代理中配置 CORS 头
    • +
  • 连接超时: 检查服务器地址和端口是否正确
    • +
  • 401 错误: 检查 API Key 是否正确

+# gRPC 配置指南
+
+## 问题诊断
+
+如果您在测试 gRPC 连接时遇到 "Failed to fetch" 错误，这通常是由以下原因造成的：
+
+### 1. Headscale 服务器配置问题
+
+**问题**: Headscale 默认只提供 gRPC API，不提供 gRPC-Web API
+**解决方案**: 需要配置 gRPC-Web 代理
+
+#### 方法 A: 使用 Envoy 代理 (推荐)
+
+创建 `envoy.yaml` 配置文件：
+
+```yaml
+static_resources:
+  listeners:
+  - name: listener_0
+    address:
+      socket_address: { address: 0.0.0.0, port_value: 8080 }
+    filter_chains:
+    - filters:
+      - name: envoy.filters.network.http_connection_manager
+        typed_config:
+          "@type": type.googleapis.com/envoy.extensions.filters.network.http_connection_manager.v3.HttpConnectionManager
+          codec_type: auto
+          stat_prefix: ingress_http
+          route_config:
+            name: local_route
+            virtual_hosts:
+            - name: local_service
+              domains: ["*"]
+              routes:
+              - match: { prefix: "/" }
+                route:
+                  cluster: headscale_service
+                  timeout: 0s
+                  max_stream_duration:
+                    grpc_timeout_header_max: 0s
+              cors:
+                allow_origin_string_match:
+                - prefix: "*"
+                allow_methods: GET, PUT, DELETE, POST, OPTIONS
+                allow_headers: keep-alive,user-agent,cache-control,content-type,content-transfer-encoding,custom-header-1,x-accept-content-transfer-encoding,x-accept-response-streaming,x-user-agent,x-grpc-web,grpc-timeout,authorization
+                max_age: "1728000"
+                expose_headers: custom-header-1,grpc-status,grpc-message
+          http_filters:
+          - name: envoy.extensions.filters.http.grpc_web.v3.GrpcWeb
+            typed_config:
+              "@type": type.googleapis.com/envoy.extensions.filters.http.grpc_web.v3.GrpcWeb
+          - name: envoy.extensions.filters.http.cors.v3.Cors
+            typed_config:
+              "@type": type.googleapis.com/envoy.extensions.filters.http.cors.v3.Cors
+          - name: envoy.extensions.filters.http.router.v3.Router
+            typed_config:
+              "@type": type.googleapis.com/envoy.extensions.filters.http.router.v3.Router
+  clusters:
+  - name: headscale_service
+    connect_timeout: 0.25s
+    type: logical_dns
+    http2_protocol_options: {}
+    lb_policy: round_robin
+    load_assignment:
+      cluster_name: headscale_service
+      endpoints:
+      - lb_endpoints:
+        - endpoint:
+            address:
+              socket_address:
+                address: vpn.ownding.xyz
+                port_value: 50443
+```
+
+启动 Envoy:
+```bash
+docker run -d -p 8080:8080 -v $(pwd)/envoy.yaml:/etc/envoy/envoy.yaml envoyproxy/envoy:v1.22-latest
+```
+
+然后在设置中使用：
+- Server Address: `localhost` (或您的服务器地址)
+- Port: `8080`
+- Enable TLS: `false` (Envoy 处理 TLS)
+
+#### 方法 B: 使用 grpcwebproxy
+
+```bash
+# 安装 grpcwebproxy
+go install github.com/improbable-eng/grpc-web/go/grpcwebproxy@latest
+
+# 启动代理
+grpcwebproxy \
+  --backend_addr=localhost:50443 \
+  --run_tls_server=false \
+  --allow_all_origins \
+  --backend_tls_noverify
+```
+
+### 2. 网络连接问题
+
+**检查项目**:
+- 确保 Headscale 服务器可访问
+- 检查防火墙设置
+- 验证端口是否正确开放
+
+**测试连接**:
+```bash
+# 测试基本连接
+telnet vpn.ownding.xyz 50443
+
+# 或使用 curl 测试 HTTP 连接
+curl -v http://vpn.ownding.xyz:8080
+```
+
+### 3. CORS 问题
+
+如果您看到 CORS 错误，需要在 gRPC-Web 代理中配置 CORS 头。
+
+### 4. TLS 配置问题
+
+**如果启用了 TLS**:
+- 确保证书有效
+- 检查证书是否包含正确的域名
+- 考虑在开发环境中暂时禁用 TLS
+
+## 推荐配置
+
+### 开发环境
+```
+Server Address: localhost
+Port: 8080 (Envoy 代理端口)
+Enable TLS: false
+Timeout: 10000ms
+API Key: 您的 Headscale API Key
+```
+
+### 生产环境
+```
+Server Address: your-headscale-server.com
+Port: 443 (通过反向代理)
+Enable TLS: true
+Timeout: 10000ms
+API Key: 您的 Headscale API Key
+```
+
+## 故障排除步骤
+
+1. **验证 Headscale 服务器运行状态**
+   ```bash
+   # 检查 gRPC 端口
+   netstat -tlnp | grep 50443
+   ```
+
+2. **测试 REST API 连接**
+   - 确保现有的 REST API 功能正常工作
+   - 这验证了基本的网络连接
+
+3. **检查浏览器开发者工具**
+   - 查看 Network 标签页中的错误详情
+   - 检查 Console 中的 JavaScript 错误
+
+4. **逐步测试**
+   - 先测试基本的 HTTP 连接
+   - 再测试 gRPC-Web 代理
+   - 最后测试完整的 gRPC 功能
+
+## 当前实现说明
+
+当前的 gRPC 客户端实现是简化版本，主要用于演示概念。在生产环境中，您需要：
+
+1. 配置适当的 gRPC-Web 代理
+2. 使用正确的 protobuf 编码
+3. 实现完整的错误处理
+4. 添加重试机制
+
+## 联系支持
+
+如果您仍然遇到问题，请提供以下信息：
+- Headscale 版本
+- 服务器配置
+- 错误消息的完整内容
+- 浏览器开发者工具中的网络请求详情
