好程序员Python培训Python如何调用服务接口，关于Python如何调用服务接口这个问题曾经也有不少的小伙伴询问过，本篇文章小编就给读者们实例介绍一下Python如何调用服务接口，希望对小伙伴有帮助。

下面上代码：

#! /usr/bin/env python

# coding=utf-8

import os

import sys

import time

import json

import urllib

import urllib2

from urllib import quote

from datetime import datetime

pathATM = "http://192.168.217.217:4080/invoke.json"

def fmtLen(value, length=7):

  fmt = '{0:>%d}' % (length)

  return fmt.format(value)

def changeWithdrawRule(customerId, productCode, ruleTemplateId, ruleId, operator):

  service_url_s = "http://service.xxx.com/tsService/TSRuleService_1.0.0"

  method_s = "bindCustomerWithdrawRuleTemplate"

  params_s = "parameters[]=%d¶meters[]=%d¶meters[]=%d¶meters[]=%d¶meters[]=%s" % (customerId, productCode, ruleTemplateId, ruleId, operator)

  params_s += "&url=%s&method=%s¶meterTypes[]=int¶meterTypes[]=int¶meterTypes[]=int¶meterTypes[]=int¶meterTypes[]=java.lang.String" % (service_url_s, method_s)

  url_s = pathATM + "?" + quote(params_s, safe='&=')

  data_s = urllib2.urlopen(url_s).read()

  print url_s

  return json.loads(data_s)

if __name__ == '__main__':

  start = datetime.now()

  for line in open(sys.argv[1]).xreadlines():

    fields = line.strip().split()

    customerId = int(fields[0])

    productCode = int(fields[1])

    ruleTemplateId = int(fields[2])

    ruleId = int(fields[3])

    print "start to deal customerId = " + str(customerId)

    changeWithdrawRule(customerId, productCode, ruleTemplateId, ruleId, "Case")

  end = datetime.now()

运行Python脚本，即可调用相应的接口修改数据库数据。

python ChangeCustomerRule.py text.txt

text.txt中即为参数，以空格分隔
