Python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 jsondata = {
'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 requestsresponse = 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 requestsdata = {
"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 urllib2request = 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 urllibrequest = 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 requestsclass 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 timefrom Demo2.token import AddScoresclass 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()
