python climb proper way translation

 

Open the Developer Tools page translation in the proper way, find Request URL and the corresponding data in the Headers section.

 

Import urllib.request
 Import urllib.parse
 Import json 

Content = the INPUT ( ' Please enter the content to be translated: ' ) 

# _O be removed, otherwise they will be the first error_code: error 50 
url = ' http://fanyi.youdao.com/ Translate? smartresult = dict & smartresult = rule ' 

Data = {}
 # developer tools there are, i and doctype key essential 
Data [ ' I ' ] = Content 
Data [ ' from ' ] = ' the AUTO ' 
Data [ ' to ' ] = ' AUTO '
data['smartresult']='dict'
data['client']='fanyideskweb'
data['salt']='15695569180611'
data['sign']='5b0565493d812bc5e713b895c12d615d'
data['doctype']='json'
data['version']='2.1'
data['keyfrom' ] = ' Fanyi.web ' 
Data [ ' Action ' ] = ' FY_BY_REALTTIME ' 

# the type of request dictionary data into url coding, coding type and converted to' utf-8 'type of 
data = urllib.parse.urlencode ( data) .encode ( ' UTF-. 8 ' ) 

# request data in response to the result url 
response = the urllib.request.urlopen (url, data) 

# read return data content, decode the data is returned to the format conversion STR 
HTML response = .read (). decode ( ' UTF-. 8 ' ) 

# use json strings to the dictionary 
target = json.loads (HTML) 

# results key in key 'translateResult' three-list = = 'tgt'In 
Print (" Translation Results:% S " % (target [ ' translateResult ' ] [0] [0] [ ' TGT ' ]))

 

　　

This might be the proper way above a lot to the page is not identified in the manual access, but access code.

At this point we can add ' the User-Agent ' agent. The purpose is achieved by setting the User Agent hide their identity, under normal circumstances is through the browser User-Agent to recognize.

 

UA set by calling urllib.request.Request ().

 

class urllib.request.Request(url, data=None, headers={}, origin_req_host=None, unverifiable=False, method=None)

This class is an abstraction of a URL request.

　　url should be a string containing a valid URL. 

　　headers  Should BE A #headers To the Dictionary Dictionary

 

There are two ways to set User Agent:

    1. Request object when creating, fill in the headers parameter (includes User Agent information), the Headers parameter requirements for the dictionary;

    2.在创建Request对象的时候不添加headers参数，在创建完成之后，使用add_header()的方法，添加headers。
