準(zhǔn)備

首先安裝爬蟲urllib庫

pip install urllib

獲取有道翻譯的鏈接url

需要發(fā)送的參數(shù)在form data里

示例

import urllib.requestimport urllib.parseurl = ’http://fanyi.youdao.com/translate_o?smartresult=dict&smartresult=rule’data = {}data[’i’] = ’i love python’data[’from’] = ’AUTO’data[’to’] = ’AUTO’data[’smartresult’] = ’dict’data[’client’] = ’fanyideskweb’data[’salt’] = ’16057996372935’data[’sign’] = ’0965172abb459f8c7a791df4184bf51c’data[’lts’] = ’1605799637293’data[’bv’] = ’f7d97c24a497388db1420108e6c3537b’data[’doctype’] = ’json’data[’version’] = ’2.1’data[’keyfrom’] = ’fanyi.web’data[’action’] = ’FY_BY_REALTlME’data = urllib.parse.urlencode(data).encode(’utf-8’)response = urllib.request.urlopen(url,data)html = response.read().decode(’utf-8’)print(html)

運行會出現(xiàn)50的錯誤，這里需要將url鏈接的_o刪除掉

刪除后運行成功

但是這個結(jié)果看起來還是太復(fù)雜，需要在進(jìn)行優(yōu)化

導(dǎo)入json，然后轉(zhuǎn)換成字典進(jìn)行過濾

import urllib.requestimport urllib.parseimport jsonurl = ’http://fanyi.youdao.com/translate?smartresult=dict&smartresult=rule’data = {}data[’i’] = ’i love python’data[’from’] = ’AUTO’data[’to’] = ’AUTO’data[’smartresult’] = ’dict’data[’client’] = ’fanyideskweb’data[’salt’] = ’16057996372935’data[’sign’] = ’0965172abb459f8c7a791df4184bf51c’data[’lts’] = ’1605799637293’data[’bv’] = ’f7d97c24a497388db1420108e6c3537b’data[’doctype’] = ’json’data[’version’] = ’2.1’data[’keyfrom’] = ’fanyi.web’data[’action’] = ’FY_BY_REALTlME’data = urllib.parse.urlencode(data).encode(’utf-8’)response = urllib.request.urlopen(url,data)html = response.read().decode(’utf-8’)req = json.loads(html)result = req[’translateResult’][0][0][’tgt’]print(result)

但是這個程序只能翻譯一個單詞，用完就廢了。于是我在進(jìn)行優(yōu)化

import urllib.requestimport urllib.parseimport jsondef translate(): centens = input(’輸入要翻譯的語句:’) url = ’http://fanyi.youdao.com/translate?smartresult=dict&smartresult=rule’ head = {}#增加請求頭，防反爬蟲 head[’User-Agent’] = ’Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.198 Safari/537.36’ data = {}#帶上from data的數(shù)據(jù)進(jìn)行請求 data[’i’] = centens data[’from’] = ’AUTO’ data[’to’] = ’AUTO’ data[’smartresult’] = ’dict’ data[’client’] = ’fanyideskweb’ data[’salt’] = ’16057996372935’ data[’sign’] = ’0965172abb459f8c7a791df4184bf51c’ data[’lts’] = ’1605799637293’ data[’bv’] = ’f7d97c24a497388db1420108e6c3537b’ data[’doctype’] = ’json’ data[’version’] = ’2.1’ data[’keyfrom’] = ’fanyi.web’ data[’action’] = ’FY_BY_REALTlME’ data = urllib.parse.urlencode(data).encode(’utf-8’) req = urllib.request.Request(url,data,head) response = urllib.request.urlopen(req) html = response.read().decode(’utf-8’) req = json.loads(html) result = req[’translateResult’][0][0][’tgt’] # print(f’中英互譯的結(jié)果：{result}’) return resultt = translate()print(f’中英互譯的結(jié)果：{t}’)

優(yōu)化完成，效果還行。
