The HTTP 401 unauthorized error is returned when Python simulates an HTTPS request.

In the Python Web, the rest api usage example-an online translation tool built on the Cloud Platform + cloud service, using Python to simulate HTTPS requests;

The httplib module is used at the beginning. The Code is as follows:

 

header = {"Content-type": "application/json", "Accept": "*/*" }params = { 'source':'en', 'target':'es', 'text':match.group(1) }        data = urllib.urlencode(params)surl = urlparse('https://gateway.watsonplatform.net/language-translation/api/v2/translate')#surl = urlparse('https://www.baidu.com/')resContent = ''try:conn = httplib.HTTPSConnection(surl.netloc) conn.request('GET', surl.path + '?' + data)response = conn.getresponse()resContent = data + "" + getAllAttrs(response) #response.read() #except:info=sys.exc_info()resContent = getAllAttrs(info[0]) + getAllAttrs(info[1])

After some searches, it was found that httplib does not support such requests that require authentication;

 

The following code is successfully changed:

 

Params = {'source': 'en', 'target': 'els', 'text': match. group (1)} surl = 'https: // gateway.watsonplatform.net/language-translation/api/v2/translate? '+ Urllib. urlencode (params) resContent = ''try: passman = urllib2.HTTPPasswordMgrWithDefaultRealm () # create a Domain Verification object passman. add_password (None, surl, "c9819718-4660-441c-9df7-07398950ea44", "qUvrJPSdPgOx") # Set the domain address, user name and password auth_handler = urllib2.HTTPBasicAuthHandler (passman) # generate a handler for processing authentication with remote hosts opener = urllib2.build _ opener (auth_handler) # Return an openerDirector instance urllib2.install _ opener (opener) # Install an openerDirector instance By default. Response = urllib2.urlopen (surl) # Open the URL link and return the Response object resContent = response. read () # read response content failed T: info = sys. exc_info () resContent = getAllAttrs (info [0]) + getAllAttrs (info [1]) # obtain exception details

The following modules support authentication requests:

Httplib2, urllib2, requests, pycurl

But the Python 2.7.10 I installed only includes urllib2 by default, so I chose to use it.
