使用的方法

  1. #coding:utf-8
  2. import requests
  3. import string
  4. import time
  5. import hashlib
  6. import json
  7. from PyPDF2.pdf import PdfFileReader, PdfFileWriter, ContentStream
  9. #init
  10. api_url = "http://api.fanyi.baidu.com/api/trans/vip/translate"
  11. my_appid = "你的appid"
  12. cyber = "你的appkey"
  15. ## 处理pdf
  16. def getDataUsingPyPdf(filename):  
  17.     pdf = PdfFileReader(open(filename, "rb"))  
  18.     content = ""  
  19.     num = pdf.getNumPages()
  20.     for i in range(0, num):  
  21.         extractedText = pdf.getPage(i).extractText()
  22.         content +=  extractedText + "\n"  
  23.     return content  
  25. def translate(word):
  26.     #init salt and final_sign
  27.     salt = str(time.time())[:10]
  28.     final_sign = str(my_appid)+word+salt+cyber
  29.     final_sign = hashlib.md5(final_sign.encode("utf-8")).hexdigest()
  30.     #其中form和to可以区别en,zh构造请求参数
  31.     paramas = {
  32.         'q':word,
  33.         'from':'en',
  34.         'to':'zh',
  35.         'appid':'%s'%my_appid,
  36.         'salt':'%s'%salt,
  37.         'sign':'%s'%final_sign
  38.         }
  39.     my_url = api_url+'?appid='+str(my_appid)+'&q='+word+'&from='+'zh'+'&to='+'en'+'&salt='+salt+'&sign='+final_sign
  40.     response = requests.get(api_url,params = paramas).content
  41.     #content = str(response,encoding = "utf-8")
  42.     content = str(response)
  43.     print(content)
  44.     json_reads = json.loads(content)
  45.     return json_reads['trans_result'][0]['dst']+" "  
  47. content = getDataUsingPyPdf("test.pdf")
  48. clist = content.split(".")
  49. i=0
  50. while(i<clist.__len__()):
  51.     print(translate(clist[i].replace("\n"," ")))
  52.     i+=1
