正常的话应该不放过任何一个可能的 err 返回，然后尽量在最上层集中处理错误（因为这个简单场景其实不需要专门关心、单独处理每一条路径可能的每一种错误），基本就是接住之后触发重试即可。如果担心 panic 那么也总是可以套一层 goroutine 然后 defer 块里 recover() 检查并同样触发重试。

_{也就是写 Go 可以方便地静默无视错误了。比方说 Rust 的错误处理你要么写 ?（这意味着你会把 Err 抛到上一层）要么 unwrap()（这会十分扎眼，并且很明显每处这种地方，万一确实错误了进程就会崩溃）。总之要说国服 maimai NET 是错误处理的试金石也没什么问题}

看来还是要整理下代码把错误处理弄一起……有点一坨了

panic位置：

maimaidx-prober/proxy/cmd/maimaidx-prober-proxy/prober_api.go

Line 86 in e59c669

respText, timeoutErr = io.ReadAll(resp.Body)

前面其实已经出问题了：

maimaidx-prober/proxy/cmd/maimaidx-prober-proxy/prober_api.go

Lines 82 to 83 in e59c669

 req, _ := http.NewRequest(http.MethodGet, "https://maimai.wahlap.com/maimai-mobile/record/musicGenre/search/?genre=99&diff="+strconv.Itoa(i), nil) 

 var err error

：net/http: TLS handshake timeout

然而，错误判断却写在了它后面：

maimaidx-prober/proxy/cmd/maimaidx-prober-proxy/prober_api.go

Lines 87 to 89 in e59c669

 if err == nil && resp != nil && timeoutErr == nil { 

 break 

 }

当然，由于华立服务器很不稳定，每一次错误的位置和种类也不一定一样……
