参考 Linkerd起步——之本地运行

我们做如下变更：

服务端把index.html变为response.json

{"name":"James","nation":"china","msg":"Hello World."}

增加一个自动的客户端请求request.py

import urllib
import urllib.request as urllib2
import requests
import threading,time

class SendRequest(threading.Thread):
  def __init__(self,interval,count):
    threading.Thread.__init__(self)
    self.interval = interval
    self.count = count
  def run(self):
    try:
      url = "http://localhost:4140/response.json"
      # 注意这是服务名
      headers={"Host":"web"}
      result = requests.get(url,headers=headers)
      print(time.strftime('%Y-%m-%d %X',time.localtime())+" - "+str(self.count)+" - "+result.text)
      self.count = self.count+1
      #time.sleep(1)
    except Exception as e:
      print(e)
    finally:
      SendRequest(self.interval,self.count).start()

if __name__ == '__main__':
  count = 1
  SendRequest(0.1,count).start()

运行请求客户端：

$ python request.py

运行图如下：
