根因分析

服务器端认证拦截器拒绝了请求，因为授权元数据（bearer token、API key）缺失或验证失败。

English

The server-side auth interceptor rejected the request because the authorization metadata (bearer token, API key) was missing or failed validation.

解决方案

  1. 95% 成功率 
    md := metadata.Pairs("authorization", "Bearer "+token)
ctx = metadata.NewOutgoingContext(ctx, md)
resp, err := client.Get(ctx, req)
  2. 93% 成功率 
    func authUnary(token string) grpc.UnaryClientInterceptor {
    return func(ctx context.Context, method string, req, reply any, cc *grpc.ClientConn, inv grpc.UnaryInvoker, opts ...grpc.CallOption) error {
        ctx = metadata.AppendToOutgoingContext(ctx, "authorization", "Bearer "+token)
        return inv(ctx, method, req, reply, cc, opts...)
    }
}
conn, _ := grpc.NewClient(addr, grpc.WithUnaryInterceptor(authUnary(token)))

无效尝试

常见但无效的做法:

  1. 98% 失败

    gRPC method names are fixed; query strings are not transmitted. Token never reaches the server.

  2. 85% 失败

    Leaks the token into logs and business payloads; bypasses standard interceptor checks.
