我的 net/http post 方法给出 100% cpu 使用率

来源：stackoverflow 2024-04-01 08:45:36 0浏览收藏

知识点掌握了，还需要不断练习才能熟练运用。下面golang学习网给大家带来一个Golang开发实战，手把手教大家学习《我的 net/http post 方法给出 100% cpu 使用率》，在实现功能的过程中也带大家重新温习相关知识点，温故而知新，回头看看说不定又有不一样的感悟！

问题内容

我有一个带有 net/http 和 julienschmidt/httprouter 的 web 服务器。我不知道为什么，但如果我发布一个“大”数据，比如来自 </code> 的数百个换行符，我的 go 服务器就会崩溃。</p> <p>我已经尝试使用 goroutine 使 <code>for _, value := range target</code> 从主线程中排除并尝试增加 ulimit，但似乎不起作用代码：</p> <pre class="brush:php;toolbar:false;">func CreateRoute(w http.ResponseWriter, r *http.Request, ps httprouter.Params) { r.ParseMultipartForm(0) Title, Caption, Target := r.Form["title"], r.Form["caption"], r.Form["target"] if len(Title) > 0 && len(Caption) > 0 && len(Target) > 0 { CampaignId := helper.Md5Gen(time.Now().String()) target := strings.Split(Target[0], "\n") for _, value := range target { value = strings.Replace(value, "\r", "", -1) if len(value) > 6 { data := structs.CampaignTarget{ CampaignId: CampaignId, PhoneNumber: value, IsExecuted: false, ExecutedBy: "", IsSuccess: false, SendAt: int64(0), Username: LoggedUsername(w, r), } database, err := helper.DataDatabase() if err == nil { database.C("xxx").Insert(&data) } } } SavedFileName := "" file, handler, err := r.FormFile("media") if err == nil { path := "/xxx/path/" + LoggedUsername(w, r) err := os.MkdirAll(path, os.ModePerm) if err != nil { http.Error(w, "Problem with folder creation", 500) return } defer file.Close() SavedFileName = fmt.Sprintf("%v-%v", helper.Md5Gen(time.Now().String()), handler.Filename) f, err := os.OpenFile(path+"/"+SavedFileName, os.O_WRONLY|os.O_CREATE, 0666) if err != nil { http.Error(w, "Failed to Write File", 500) return } defer f.Close() io.Copy(f, file) } data := structs.Campaign{ ID: CampaignId, Title: Title[0], Caption: Caption[0], TotalTarget: len(target), Media: SavedFileName, Username: LoggedUsername(w, r), CreatedAt: time.Now().Unix(), } database, err := helper.DataDatabase() if err == nil { database.C("xx").Insert(&data) } } }</pre><br><h2 class="daan">解决方案</h2><br><p>按换行符进行拆分可能是一项昂贵的操作，其中要拆分的字符串的所有内容都是换行符。</p> <pre class="brush:golang;toolbar:false;">target := strings.split(target[0], "\n") </pre> <p>如果您想分割换行符，请考虑使用 <code>bufio.scanner</code> 代替</p> <pre class="brush:golang;toolbar:false;">scanner := bufio.NewScanner(strings.NewReader("foo\nbar\nbaz")) for scanner.Scan() { fmt.Println(scanner.Text()) } </pre> <p><a target='_blank'
