 6 response.encoding = ‘utf-8‘
 7 result = response.text
 8 print(type(result), result)
 9 
10 # <class ‘str‘> {"weatherinfo":{"city":"懷柔","cityid":"101010500","temp":"9","WD":"南風",
 

11 # "WS":"1級","SD":"29%","WSE":"1","time":"10:25","isRadar":"1","Radar":"JC_RADAR_AZ9010_JB",
12 # "njd":"暫無實況","qy":"1007"}}
13 
14 
15 dic = json.loads(result)
16 print(type(dic), dic)
17 
18 # <class ‘dict‘> {‘weatherinfo‘: {‘city‘: ‘懷柔‘, ‘cityid‘: ‘101010500‘, ‘temp‘: ‘9‘, ‘WD‘: ‘南風‘,
19 # ‘WS‘: ‘1級‘, ‘SD‘: ‘29%‘, ‘WSE‘: ‘1‘, ‘time‘: ‘10:25‘, ‘isRadar‘: ‘1‘, ‘Radar‘: ‘JC_RADAR_AZ9010_JB‘,
 

20 # ‘njd‘: ‘暫無實況‘, ‘qy‘: ‘1007‘}}

1.檢查QQ在線情況

 1 import requests
 2  
 3 # 使用第三方模塊requests發送HTTP請求，或者XML格式內容
 4 r = requests.get(‘http://www.webxml.com.cn//webservices/qqOnlineWebService.asmx/qqCheckOnline?qqCode=123456789‘)
 5 result = r.text  #xml的字符串類型
 6  
 7  
 8 from xml.etree import ElementTree as ET
 
 9  
10 # 解析XML格式內容
11 node = ET.XML(result)  #XML接收一個字符串，格式化為特殊的對象
12 print(node)
13  
14 # 獲取內容
15 if node.text == "Y":   #特殊的對象可以訪問自己各個節點的信息
16     print("在線")
17 else:
18     print("離線")

2.火車站點詳情

 1 import requests
 2  
 3 from xml.etree import ElementTree as ET
 4  
 5 # 使用第三方模塊requests發送HTTP請求，或者XML格式內容
 6 r = requests.get(
 7     ‘http://www.webxml.com.cn/WebServices/TrainTimeWebService.asmx/getDetailInfoByTrainCode?TrainCode=G666&UserID=‘)
 8 result = r.text
 9  
10 # 解析XML格式內容,把字符串解析成XML
11 root = ET.XML(result)
12  
13 print(root.tag)
14 for node in root:
15     print(node)
16     for node_node in node:
17         print(node_node)
18         for node_node_node in node_node:
19             print(node_node_node)
