我正在尝试将此代码段从PHP转换为Python(编程新手),并且我发现这样做有困难:
我想要转换的PHP如下:
$fp = fsockopen($whmcsurl, 80, $errno, $errstr, 5);
if ($fp) {
$querystring = "";
foreach ($postfields AS $k=>$v) {
$querystring .= "$k=".urlencode($v)."&";
}
$header="POST ".$whmcsurl."modules/servers/licensing/verify.php HTTP/1.0\r\n";
$header.="Host: ".$whmcsurl."\r\n";
$header.="Content-type: application/x-www-form-urlencoded\r\n";
$header.="Content-length: ".@strlen($querystring)."\r\n";
$header.="Connection: close\r\n\r\n";
$header.=$querystring;
$data="";
@stream_set_timeout($fp, 20);
@fputs($fp, $header);
$status = @socket_get_status($fp);
while (!@feof($fp)&&$status) {
$data .= @fgets($fp, 1024);
$status = @socket_get_status($fp);
}
@fclose ($fp);
}
我编写的相应Python代码如下:
fp = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
fp.connect(("my ip", 80))
if (fp):
querystring = ""
#print postfields
for key in postfields:
querystring = querystring+key+"="+urllib.quote(str(postfields[key]))+"&"
header = "POST "+whmcsurl+"modules/servers/licensing/verify.php HTTP/1.0\r\n"
header+="Content-type: application/x-www-form-urlencoded\r\n"
header+="Content-length: "+str(len(querystring))+"\r\n"
header+="Connection: close\r\n\r\n"
#header+=querystring
data=""
request = urllib2.Request(whmcsurl,querystring,header)
response = urllib2.urlopen(request)
data = response.read()
在这里,我遇到以下错误:
request = urllib2.Request(whmcsurl,querystring,header)
File "/usr/lib64/python2.6/urllib2.py", line 200, in __init__
for key, value in headers.items():
AttributeError: 'str' object has no attribute 'items'
所以我猜测Python期待标题的字典。但PHP将其作为字符串发送。
我可以知道如何解决这个问题吗?

你太过复杂了,相当远。 Python会为您处理大部分内容。无需自己打开套接字,也不需要构建标头和HTTP开放行。
from urllib import urlencode
from urllib2 import urlopen
params = urlencode(postfields)
url = whmcsurl + 'modules/servers/licensing/verify.php'
response = urlopen(url, params)
data = response.read()
urlopen()
接受第二个参数,即要在POST
请求中发送的数据;该库负责计算主体的长度,并设置适当的标题。最重要的是,它使用另一个库httplib
来处理套接字连接并生成有效的头和HTTP请求行。
POST主体使用urllib.urlencode()
进行编码,它也会为您正确引用。
您可能还想查看external requests
library,它提供了一个更易于使用的API:
import requests
response = requests.post(whmcsurl + 'modules/servers/licensing/verify.php', params=params)
data = response.content # or response.text for decoded content, or response.json(), etc.

您的标题应如下所示
headers = { "Content-type" : "application/x-www-form-urlencoded" };
