上一篇文章測試了解析測試的HTML源碼，獲取需要的元素值。

如下的測試代碼模仿網上示例，但是經過了我的理解和實際測試驗證。測試流程如下：

測試淘票票支持的城市

步驟1： 進入淘票票官網

步驟2： 找到url

步驟3： 復制請求的URL到代碼中

url =‘https://dianying.taobao.com/cityAction.json?activityId&_ksTS=1639658592150_137&jsoncallback=jsonp138&action=cityAction&n_s=new&event_submit_doGetAllRegion=true’

步驟4：以及請求頭添加代碼發送的Headers信息

headers = {

‘accept’:‘text/javascript, application/javascript, application/ecmascript, application/x-ecmascript, */*; q=0.01’,

‘cookie’:‘miid=149457062080870528; enc=QY6eoneP3TUCAdTp8d3MJOgJnMLqmmIpQS+gLj6EDPuxew065EXVCvNrEdIXmozlUufg5zUvNyZ+YTQ2V4p9cw==; cna=4Nz+F9mZ91gCAbfAW780HLti; thw=cn; hng=TW|zh-TW|TWD|158; t=17c5c8356ce22ddc6fe08337efa1cadc; cookie2=1adeccce649568d2b7fcd5576f4d11cb; v=0; _tb_token_=3e783b73fe3e7; xlly_s=1; l=eBa1BNl7QPMcNlJvBOfwlurza77tJIRAguPzaNbMiOCP_Z5H5tihW6QGtHTMCnGVhsCMR35T8LL0BeYBqC2sjqj4axom4vkmn; tfstk=cQM5BVxpvabSAfAFU0tV4EEDoKwFaBLbmQa-VXenIR-Msnn7ksb5QPT03Xb0LkEf.; isg=BKamD7Te-4rYW5CJrdtUKgGr9xwoh-pBST3dRZBPqkmkE0Yt-BftUc_taw-fu-JZ’,

‘referer’:‘https://dianying.taobao.com/?pid=mm_25282911_3455987_122436732’,

‘user-agent’:‘Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/96.0.4664.110 Safari/537.36’,

‘x-requested-with’:‘XMLHttpRequest’

}

步驟5：發送請求獲取響應值

request = urllib.request.Request(url=url, headers=headers)

response = urllib.request.urlopen(request)

content = response.read().decode(‘utf-8’)

# print(content)

打印的響應值并非是標準Json格式

需要將返回的字符串做處理，才能成為標準的Json字符串。

步驟6， 返回字符串處理為標準的JSON字符串

# split

content = content.split(’(’)[1].split(’)’)[0]

print(content)

步驟7，使用jsonPath提取支持的城市名稱

with open(‘tpp.json’, ‘w’, encoding=‘utf-8’)as f:

f.write(content)

jsObj = json.load(open(‘tpp.json’, ‘r’, encoding=‘utf-8’))

city_list = jsonpath.jsonpath(jsObj, ‘$…regionName’)

print(city_list)

輸出：
