根因分析

客户端请求的索引超出了响应中列表或数组的大小。

English

Client requested an index that exceeds the size of a list or array in the response.

generic

解决方案

  1. 95% 成功率 Validate the index before making the request. 
    if idx < 0 || idx >= len(items) {
    return fmt.Errorf("index out of range")
}
resp, err := client.GetItem(ctx, &pb.GetRequest{Index: int32(idx)})
  2. 90% 成功率 Fetch the entire list and then access the index locally. 
    listResp, err := client.GetList(ctx, &pb.ListRequest{})
if err != nil { return err }
if idx < 0 || idx >= len(listResp.Items) {
    return fmt.Errorf("index out of range")
}
item := listResp.Items[idx]

无效尝试

常见但无效的做法:

  1. Assume the server will handle out-of-range gracefully. 100% 失败

    The server returns an error; it does not auto-correct.

  2. Use negative indexing hoping it wraps around. 90% 失败

    Protobuf does not support negative indexing; it will still fail.
