func GetAskQuestionData(userId int, language, question string) (ai_common.AskQuestionData, error) { resp := ai_common.AskQuestionData{} dbUser, isExist := dbrespository.GetUserById(userId, models.NormalStatus) if !isExist { return resp, e...-Go服务器开发

要使用协程优化 GetAskQuestionData 函数，我们可以并发地调用一些耗时的操作，例如从数据库或服务中获取用户健康信息。通过使用 sync.WaitGroup 可以等待所有的协程完成。

下面是一个示例，展示如何将多个独立的数据请求并行化：

package main

import (
	"errors"
	"sync"
	"time"

	"your_project/ai_common"
	"your_project/common"
	"your_project/error_code"
	"your_project/models"
	"your_project/user_service"
)

func GetAskQuestionData(userId int, language, question string) (ai_common.AskQuestionData, error) {
	resp := ai_common.AskQuestionData{}
	dbUser, isExist := dbrespository.GetUserById(userId, models.NormalStatus)
	if !isExist {
		return resp, errors.New(error_code.AccountDelError, common.GetErrorMsg(error_code.AccountDelError, language))
	}

	userHealthInfo := ai_common.UserHealthInfo{
		UserId:  dbUser.UnionId,
		Name:    dbUser.Name,
		Account: dbUser.Account,
		Age:     (int(time.Now().Unix()) - dbUser.Birthday) / common.ONE_YEAR,
		Sex:     dbUser.Sex,
	}
	resp.Question = question

	var wg sync.WaitGroup
	wg.Add(7) // 我们有七个并发请求要处理

	go func() {
		defer wg.Done()
		userHealthInfo.UserHealthStatus = user_service.GetUserHealthStatus(userId, language)
	}()

	go func() {
		defer wg.Done()
		userHealthInfo.UserLifestyle = user_service.GetUserLifestyle(userId)
	}()

	go func() {
        defer wg.Done()
        userHealthInfo.UserOccupational = user_service.GetUserOccupational(userId)
    }()

	go func() {
        defer wg.Done()
        userHealthInfo.CurrentMedicalRecord = user_service.GetUserCurrentMedicalRecord(userId)
    }()

	go func() {
        defer wg.Done()
        userHealthInfo.UserSymptomsRecord = user_service.GetUserSymptomsRecord(userId)
    }()

	go func() {
        defer wg.Done()
        userHealthInfo.UserHealthDiary = user_service.GetUserHealthDiary(userId)
    }()

	go func() {
        defer wg.Done()
        userHealthInfo.UserHealthGoals = user_service.GetUserHealthGoals(userId)
    }()

	go func() {
        defer wg.Done()
        userHealthInfo.CommonVaccinesList = user_service.GetUserCommonVaccines(userId)
    }()

	wg.Wait() // 等待所有的 goroutine 完成

	resp.UserHealthInfo = userHealthInfo
	referenceParameters := hospital_standards_service.GetReferenceParameters(userHealthInfo.Age, userHealthInfo.Sex, language)
	resp.ReferenceParameters = referenceParameters

	return resp, nil
