一、导入模块

import urllib.requestimport urllib.parseimport json

二、指定url,构造headers，构造请求参数

1.指定url

url = 'http://fanyi.baidu.com/v2transapi'

2.构造headers

headers = {    'Host': 'fanyi.baidu.com',    'Connection': 'keep-alive',    # 'Content-Length': '7',  不能固定长度    'Accept': 'application/json, text/javascript, */*; q=0.01',    'Origin': 'http://fanyi.baidu.com',    'X-Requested-With': 'XMLHttpRequest',    'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.108 Safari/537.36',    'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8',    'Referer': 'http://fanyi.baidu.com/translate',    # 'Accept-Encoding': 'gzip, deflate', #不接受压缩文件    'Accept-Language': 'zh-CN,zh;q=0.9',    'Cookie': 'BIDUPSID=9F5816DD3088F4291EA4C12FFC2ABCDE; BAIDUID=78AF1CE91C8F84BD601F6E2778C618DA:FG=1; PSTM=1513827071; FP_UID=49cb193525cef45caf0af69c1e64ccf6; BDRCVFR[DDAxsax1-qs]=mk3SLVN4HKm; H_PS_PSSID=1454_21125_25177; PSINO=2; BDORZ=FFFB88E999055A3F8A630C64834BD6D0; locale=zh; Hm_lvt_64ecd82404c51e03dc91cb9e8c025574=1514168525; Hm_lpvt_64ecd82404c51e03dc91cb9e8c025574=1514168525; to_lang_often=%5B%7B%22value%22%3A%22en%22%2C%22text%22%3A%22%u82F1%u8BED%22%7D%2C%7B%22value%22%3A%22zh%22%2C%22text%22%3A%22%u4E2D%u6587%22%7D%5D; REALTIME_TRANS_SWITCH=1; FANYI_WORD_SWITCH=1; HISTORY_SWITCH=1; SOUND_SPD_SWITCH=1; SOUND_PREFER_SWITCH=1; from_lang_often=%5B%7B%22value%22%3A%22zh%22%2C%22text%22%3A%22%u4E2D%u6587%22%7D%2C%7B%22value%22%3A%22en%22%2C%22text%22%3A%22%u82F1%u8BED%22%7D%5D',}

3.构造请求参数(参数格式与真实参数一致，可通过抓包工具观察）

word = 'wolf'data = {    'from': 'en',    'to': 'zh',    'query': word,    'transtype': 'realtime',    'simple_means_flag': '3',}data = urllib.parse.urlencode(data).encode('utf-8')

三、模拟请求

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

四、发送请求

reponse = urllib.request.urlopen(request)

五、获取结果(结果显示，获取的数据为assii编码）

result = reponse.read().decode('utf-8')

六、存储数据结果（需要将assii编码转化为utf-8)

1.将json格式的字符串转化为python对象

obj = json.loads(result)

2.将python对象转为json格式字符串，注意，要添加第二个参数，禁用ascii编码

string = json.dumps(obj,ensure_ascii=False)

3.将字符串以utf-8格式写入文件

with open('wolf.json','w',encoding='utf-8') as f1:    f1.write(string)
