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() | |
104 | </pre></div> | |
