python之简单的get和post请求

1.json 模块提供了一种很简单的方式来编码和解码JSON数据。其中两个主要的函数是 json.dumps() 和 json.loads() ，要比其他序列化函数库如pickle的接口少得多。下面演示如何将一个Python数据结构转换为JSON：

import json

data = {

    'name' : 'ACME',

    'shares' : 100,

    'price' : 542.23

}

json_str = json.dumps(data)

下面演示如何将一个JSON编码的字符串转换回一个Python数据结构：

data = json.loads(json_str)

2.简单的get和post请求，使用import requests

import requests

response = requests.get('http://httpbin.org/get')

print(response.text)

#通过在发送post请求时添加一个data参数，这个data参数可以通过字典构造成

import requests

data = {

    "name":"zhaofan",

    "age":23

}

response = requests.post("http://httpbin.org/post",data=data)

print(response.text)

3.GET方法，并且自定义header

# -* - coding: UTF-8 -* -

import urllib2

request = urllib2.Request("http://www.baidu.com/")

request.add_header('content-TYPE', 'application/x-www-form-urlencoded')

response = urllib2.urlopen(request)

print response.getcode()

print response.geturl()

print response.read()

POST方法，并且自定义header

# -* - coding: UTF-8 -* -

import urllib2

import urllib

request = urllib2.Request("http://passport.cnblogs.com/login.aspx")

request.add_header('content-TYPE', 'application/x-www-form-urlencoded')

data={"tbUserName":"test_username", "tbPassword":"test_password"}

response = urllib2.urlopen(request, urllib.urlencode(data))

print response.getcode()

print response.geturl()

print response.read()

4.实际测试脚本编写

# coding:utf-8

import json

import urllib2

import requests

class AddScores:

    def __init__(self):

        pass

    def getToken(self):  # 获取token值

        url1 = 'xxxxx'#url

        r1 = requests.get(url1)

        self.tokenObj = json.loads(r1.text)#解码JSON数据

        if self.tokenObj["result"] == "success":

            print self.tokenObj["token"]

        else:

            print "failed"

        return self.tokenObj["token"]

    def personMess(self):  # 获取个人信息

        url2 = 'xxx' + self.getToken()

        r2 = requests.post(url2)

        print r2.text

    def addSco(self,resId):  # 添加分数

        data = {

            "memberId": "xxx",

            "orgCode": "xxx",

            "resourceId": resId,#传参，传resourceId

            "configName": "wsp", "resourceType": "wsp"

        }

        print "添加分数的请求参数："

        print json.dumps(data)#编码JSON

        headers = {'Content-Type': 'application/json'}

        url3 = 'xxx' + self.getToken()

        re3 = urllib2.Request(url=url3, headers=headers, data=json.dumps(data))

        response = urllib2.urlopen(re3)

        print response.read()

5.读写TXT文件

#coding:utf-8

import time

from Demo2.token import AddScores

class ResId:

    def getResId(self):

        file=open('xxxx')

        # a=file.read()

        # print a

        lId= file.readline()

        lId=lId.strip(',\n')

        while lId != '':#逐行读取数据

            print lId

            addScores = AddScores()

            addScores.getToken()

            addScores.personMess()

            addScores.addSco(lId)

            time.sleep(68)

            lId = file.readline()

            print "============================="

ResId().getResId()
