Question

尝试使用coffescript来比较来自2台服务器的get API的结果我写了下面的代码



http = require 'http'
component='frontend'
cm_app_host1='localhost:5000'
cm_app_host2='localhost:5000'#Assume some other IP
result=""
console.log url1
getResponse = (url,callbackfunc) ->
  req = http.get url, (res) ->
    status = res.statusCode
    body=''
    if status == 200
       res.on 'data', (chunk) ->
         body += chunk.toString()
       res.on 'end',() ->
         callbackfunc body
    else
      body+="ERROR"
  req.on 'error', ->
    msg = "not available"
    console.log msg


onFinish = (data) ->
  return data

compareResults = (str1,str2) ->
  console.log str1
  console.log str2
  return true #just for simplicity

j = 0
len = process.argv.length
while j < len
  campaignSendId=process.argv[2]
  console.log campaignSendId
  url1="http://"+cm_app_host1+"/cs/v1/someapi/"+campaignSendId+"?clientKey=00000000"
  url2="http://"+cm_app_host2+"/cs/v1/someapi/"+campaignSendId+"?clientKey=00000000"
  result1 = getResponse(url1, onFinish)
  result2 = getResponse(url2, onFinish)
  compareResults(result1,result2) #Gets called before we have recieved the results
  j++

http = require 'http' component='frontend' cm_app_host1='localhost:5000' cm_app_host2='localhost:5000'#Assume some other IP result="" console.log url1 getResponse = (url,callbackfunc) -> req = http.get url, (res) -> status = res.statusCode body='' if status == 200 res.on 'data', (chunk) -> body += chunk.toString() res.on 'end',() -> callbackfunc body else body+="ERROR" req.on 'error', -> msg = "not available" console.log msg onFinish = (data) -> return data compareResults = (str1,str2) -> console.log str1 console.log str2 return true #just for simplicity j = 0 len = process.argv.length while j < len campaignSendId=process.argv[2] console.log campaignSendId url1="http://"+cm_app_host1+"/cs/v1/someapi/"+campaignSendId+"?clientKey=00000000" url2="http://"+cm_app_host2+"/cs/v1/someapi/"+campaignSendId+"?clientKey=00000000" result1 = getResponse(url1, onFinish) result2 = getResponse(url2, onFinish) compareResults(result1,result2) #Gets called before we have recieved the results j++

问题是在getResponse完成之前调用compareResults，因为它返回异步。不知何故，我试图解决这个问题但最终无法弄清楚任何简单的问题。有人能帮助我吗？我是javascript的新手
