hi,新书吗?给个购买链接~~ thx;
为什么http的操作ioutil.ReadAll,后面都没有resp.Close,是不需要吗?
在一些go的书籍上都有强调ioutil.ReadAll读取后,记得调用defer close
很感谢
我试着run或build第一章的main.go,如果使用了go mod就会出现以下错误:
main.go:4:2: local import "./cache" in non-local package
main.go:5:2: local import "./http" in non-local package
删除go mod,会出现:
to create a module there, run:
cd ../.. && go mod init
这里我使用了 go mod init 或 export GOPATH=pwd
等都不能正常编译成功。请教在1.17版本如何运行代码
func (r *result) addStatistic(bucket int, stat statistic) {
if bucket > len(r.statBuckets)-1 {
newStatBuckets := make([]statistic, bucket+1)
copy(newStatBuckets, r.statBuckets)
r.statBuckets = newStatBuckets
}
s := r.statBuckets[bucket]
s.count += stat.count
s.time += stat.time
r.statBuckets[bucket] = s
}
这块代码感觉上会出现数据竞争问题,但测试却没有呢?
