python之簡單的get和post請求

1.json 模塊提供了一種很簡單的方式來編碼和解碼JSON數據。 其中兩個主要的函數是 json.dumps() 和 json.loads() ， 要比其他序列化函數庫如pickle的接口少得多。 下面演示如何將一個Python數據結構轉換為JSON：

import json

data = {
    'name' : 'ACME',
    'shares' : 100,
    'price' : 542.23
}

json_str = json.dumps(data)

下面演示如何將一個JSON編碼的字符串轉換回一個Python數據結構：

data = json.loads(json_str)

2.簡單的get和post請求，使用import requests

import requests

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

 

#通過在發送post請求時添加一個data參數，這個data參數可以通過字典構造成
import requests

data = {
    "name":"zhaofan",
    "age":23
}
response = requests.post("http://httpbin.org/post",data=data)
print(response.text)

3.GET方法，並且自定義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，並且自定義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.實際測試腳本編寫

# coding:utf-8
import json
import urllib2
import requests


class AddScores:
    def __init__(self):
        pass

    def getToken(self):  # 獲取token值
        url1 = 'xxxxx'#url
        r1 = requests.get(url1)
        self.tokenObj = json.loads(r1.text)#解碼JSON數據

        if self.tokenObj["result"] == "success":
            print self.tokenObj["token"]
        else:
            print "failed"
        return self.tokenObj["token"]

    def personMess(self):  # 獲取個人信息
        url2 = 'xxx' + self.getToken()
        r2 = requests.post(url2)
        print r2.text

    def addSco(self,resId):  # 添加分數
        data = {
            "memberId": "xxx",
            "orgCode": "xxx",
            "resourceId": resId,#傳參，傳resourceId
            "configName": "wsp", "resourceType": "wsp"
        }

        print "添加分數的請求參數："
        print json.dumps(data)#編碼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.讀寫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 != '':#逐行讀取數據
            print lId
            addScores = AddScores()
            addScores.getToken()
            addScores.personMess()
            addScores.addSco(lId)

            time.sleep(68)

            lId = file.readline()
            print "============================="


ResId().getResId()
