根因分析
gRPC 请求未包含所需的身份验证元数据(例如授权令牌),或者令牌无效。
English
The gRPC request does not include the required authentication metadata (e.g., an authorization token) or the token is invalid.
解决方案
-
95% 成功率
md := metadata.Pairs("authorization", "Bearer "+token); ctx := metadata.NewOutgoingContext(context.Background(), md); resp, err := client.Call(ctx, ...) -
85% 成功率
Implement a token provider that obtains and caches valid tokens.
无效尝试
常见但无效的做法:
-
80% 失败
This weakens security and is not advisable in production.
-
90% 失败
The server will still reject it.
