Go标准库中也自带了log库。该库是一个非常有争议的记录器，它的日志记录缺乏日志记录级别和上下文感知值之类的功能。package mainimport ("log")func init() {log.SetPrefix("TRACE: ")log.SetFlags(log.Ldate | log.Lmicroseconds | log.Llongfile)}func main() {log.Println("message")log.Fatalln("fa...
If a node is part of a line that's too long, shorten it by altering the newlines around the node and/or its children Repeat steps 2-5 until no more shortening can be done Run the base formatter (e.g.,gofmt) over the results, write these to eitherstdoutor the source file ...
We use it in some of our examples and you may find it useful too. The Go type checker does three main things. First, for every name in the program, it determines which declaration the name refers to; this is known as identifier resolution. Second, for every expression in the program, ...
crypto/rsa:message toolongforRSApublickey size 看到了golang的rsa片段源码下: iferr:=checkPub(pub);err!=nil{returnnil,err}k:=pub.Size()iflen(msg)>k-11{returnnil,ErrMessageTooLong} 意思是当内容大于key长度减去11位就报错,于是和新服务接口的对接约定大于127位取127位,目前不确定这个127由来。
