def upload(filename):
#buld post body data
boundary = '--xxxxxxxxxxxxxxxx '       http_url='http://xx.xx.com/upload.php'
data = []
data.append('--%s' % boundary)

fp=open(filename,'rb')
data.append('Content-Disposition: form-data; name="%s"; filename="%s"' % ('file',filename))
data.append('Content-Type: %s\r\n' % 'text/html')
data.append(fp.read())
fp.close()
data.append('--%s--\r\n' % boundary)

http_body = '\r\n'.join(data)
try:
req = urllib2.Request(http_url, data=http_body)
req.add_header('Content-Type', 'multipart/form-data; boundary=%s' % boundary)
res = urllib2.urlopen(req, timeout=5)
print res.read().decode('utf8')
except Exception,e:
print 'Error: %s' % e

再补充一下用html上传文件到服务器

<head>
<link rel="shortcut icon" href="favicon.ico">
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>导入数据</title>
<script type="text/javascript">
function check(form) {
if(form.file.value==''){
alert('请选择要上传的文件!');
form.file.focus();
return false;
}
return true;
}

window.onload = function() {
document.form.reset();
}
</script>
</head>

<h1 align="center">导入数据</h1>

<fieldset>
<legend><b>请选择要上传的文件: <b></legend>
<form action="http://xx.xx.com/upload.php" method="post" name="form" enctype="multipart/form-data" onsubmit="return check(this);" target="result">
<input type="file" name="file" size=50>
<input type="submit" name="upload" value="上传">
</form>
</fieldset>

<iframe name="result" frameborder=0 width="100%" height="100%" scrolling="no"></iframe>
