1. The JSON module provides a very simple way to encode and decode JSON data. Two of the main functions are json.dumps() and json.loads(), which have much fewer interfaces than other serialized libraries such as pickle. The following demonstrates how to convert a Python data structure to JSON:

'''
import json

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

json_str = json.dumps(data)

The following demonstrates how to convert a JSON-encoded string back to a Python data structure:

data = json.loads(json_str)

2. Simple get and post requests, using import requests

import requests

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

# By adding a data parameter to the post request, the data parameter can be constructed from a dictionary.
import requests

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

3.GET method and custom 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 method and custom header

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. Writing Practical Test Scripts

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

class AddScores:
    def __init__(self):
        pass

    def getToken(self):  # Get the token value
        url1 = 'xxxxx'#url
        r1 = requests.get(url1)
        self.tokenObj = json.loads(r1.text)#Decoding JSON data

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

    def personMess(self):  # Access to personal information
        url2 = 'xxx' + self.getToken()
        r2 = requests.post(url2)
        print r2.text

    def addSco(self,resId):  # Added Score
        data = {
            "memberId": "xxx",
            "orgCode": "xxx",
            "resourceId": resId,#Reference, resourceId
            "configName": "wsp", "resourceType": "wsp"
        }

        print "Request parameters for adding scores:"
        print json.dumps(data)#Coding 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. Read and write TXT files
