根因分析

服务端的认证拦截器拒绝了请求，因为 metadata 中不含有效的 bearer 令牌，或令牌已过期。

English

The server's auth interceptor rejected the request because the metadata did not contain a valid bearer token, or the token was expired.

解决方案

  1. 92% 成功率 
    md := metadata.Pairs("authorization", "Bearer "+token)
ctx = metadata.NewOutgoingContext(ctx, md)
resp, err := client.Get(ctx, req)
// or as a unary interceptor:
func auth(ctx context.Context, method string, req, reply interface{}, cc *grpc.ClientConn, inv grpc.UnaryInvoker, opts ...grpc.CallOption) error {
    ctx = metadata.AppendToOutgoingContext(ctx, "authorization", "Bearer "+getToken())
    return inv(ctx, method, req, reply, cc, opts...)
}
  2. 90% 成功率 
    type tokenAuth struct{ token string }
func (t tokenAuth) GetRequestMetadata(ctx context.Context, uri ...string) (map[string]string, error) {
    return map[string]string{"authorization": "Bearer " + t.token}, nil
}
func (t tokenAuth) RequireTransportSecurity() bool { return true }
conn, _ := grpc.Dial(addr, grpc.WithPerRPCCredentials(tokenAuth{token: tok}))

无效尝试

常见但无效的做法:

  1. 92% 失败

    An expired or malformed token is rejected deterministically on every attempt.

  2. 95% 失败

    Removes the security boundary entirely and lets unauthenticated clients reach protected handlers.
