Python爬虫【实战篇】百度翻译

先看代码

import requests

headers = {
    "User-Agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.84 Safari/537.36"}
data = {
    "from":"en",
    "to":"zh",
    "query":"student",
    "transtype":"translang",
    "simple_means_flag":"3",
    "sign":"372549.85108",
    "token":"e89a8f037aac1b51a86cbc82356949d"
}
post_url = "http://fanyi.baidu.com/v2transapi"

r = requests.post(post_url,data=data,headers=headers)
print(r.content.decode())

从代码中可以看到，所携带的请求参数比较多，可以尝试切换成手机模式进行请求。

import requests

headers = {
    "User-Agent": "Mozilla/5.0 (iPhone; CPU iPhone OS 11_0 like Mac OS X) AppleWebKit/604.1.38 (KHTML, like Gecko) Version/11.0 Mobile/15A372 Safari/604.1"
}
data = {
    "query": "学生",
    "from": "zh",
    "to": "en"
}
response = requests.post(url='https://fanyi.baidu.com/basetrans', headers=headers, data=data)
response = response.content.decode('utf-8')
print(type(response))

import json

response = json.loads(response)
print(response.get("trans")[0].get("dst"))

可以很清楚的看到，手机模式所携带的参数比较少，如果我们以后遇到电脑请求携带的参数比较多，可以切换成手机模式来进行请求，会更加容易
