| 58 | <P> | |
| 59 | Here is an example session that uses the "<tt class="samp">GET</tt>" method to retrieve | |
| 60 | a URL containing parameters: | |
| 61 | ||
| 62 | <P> | |
| 63 | <div class="verbatim"><pre> | |
| 64 | >>> import urllib | |
| 65 | >>> params = urllib.urlencode({'spam': 1, 'eggs': 2, 'bacon': 0}) | |
| 66 | >>> f = urllib.urlopen("http://www.musi-cal.com/cgi-bin/query?%s" % params) | |
| 67 | >>> print f.read() | |
| 68 | </pre></div> | |
| 69 | ||
| 70 | <P> | |
| 71 | The following example uses the "<tt class="samp">POST</tt>" method instead: | |
| 72 | ||
| 73 | <P> | |
| 74 | <div class="verbatim"><pre> | |
| 75 | >>> import urllib | |
| 76 | >>> params = urllib.urlencode({'spam': 1, 'eggs': 2, 'bacon': 0}) | |
| 77 | >>> f = urllib.urlopen("http://www.musi-cal.com/cgi-bin/query", params) | |
| 78 | >>> print f.read() | |
| 79 | </pre></div> | |
| 80 | ||
| 81 | <P> | |
| 82 | The following example uses an explicitly specified HTTP proxy, | |
| 83 | overriding environment settings: | |
| 84 | ||
| 85 | <P> | |
| 86 | <div class="verbatim"><pre> | |
| 87 | >>> import urllib | |
| 88 | >>> proxies = {'http': 'http://proxy.example.com:8080/'} | |
| 89 | >>> opener = urllib.FancyURLopener(proxies) | |
| 90 | >>> f = opener.open("http://www.python.org") | |
| 91 | >>> f.read() | |
| 92 | </pre></div> | |
| 93 | ||
| 94 | <P> | |
| 95 | The following example uses no proxies at all, overriding environment | |
| 96 | settings: | |
| 97 | ||
| 98 | <P> | |
| 99 | <div class="verbatim"><pre> | |
| 100 | >>> import urllib | |
| 101 | >>> opener = urllib.FancyURLopener({}) | |
| 102 | >>> f = opener.open("http://www.python.org/") | |
| 103 | >>> f.read() | |
