Python crawler crawls Yodo to realize the translation function

intend

First install the crawler urllib library

pip install urllib

Get the link url for Yodo Translate

The parameters to be sent are in the form data

typical example

import 
import 

url = '/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'] = ''
data['action'] = 'FY_BY_REALTlME'
data = (data).encode('utf-8')
response = (url,data)
html = ().decode('utf-8')
print(html)

Running it will give you an error of 50, here you need to remove the _o from the url link

Run successfully after deletion

But this result still looks too complex and needs to be optimized in the

Import json, then convert to dictionary for filtering

import 
import 
import json

url = '/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'] = ''
data['action'] = 'FY_BY_REALTlME'
data = (data).encode('utf-8')
response = (url,data)
html = ().decode('utf-8')

req = (html)
result = req['translateResult'][0][0]['tgt']
print(result)

But this program can only translate one word, and it's useless when it runs out. So I'm optimizing

import 
import 
import json

def translate():
  centens = input('Enter the statement to be translated:')
  url = '/translate?smartresult=dict&smartresult=rule'
  head = {}# Add request headers to prevent anti-crawlers
  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 = {}# Request with data from data
  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'] = ''
  data['action'] = 'FY_BY_REALTlME'
  data = (data).encode('utf-8')
  req = (url,data,head)
  response = (req)
  html = ().decode('utf-8')
  req = (html)
  result = req['translateResult'][0][0]['tgt']
  # print(f'Result of Chinese-English translation: {result}')
  return result
t = translate()
print(f'Results of Chinese-English Interpretation：{t}')

Optimization is complete and works fine.
