I have to POST a request to a server. In the API documentation of the website there is this example that uses cURL in PHP:

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://api.website.com');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "request=$wrapper");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
;
$data = curl_exec($ch);
curl_close($ch);

But my app is done using Python, so I tried to write something like that but this code doesn’t work:

req = urllib2.Request(url, formatted)  
response = urllib2.urlopen(req)  
html = response.read()  
print html+"\n\n"  

Can you help me write a working conversion of a PHP cURL program to Python?

Thank you!!

    It’s quite embarrassing but… the only problem with my code that uses urllib and urllib2 is… that this code do a GET and not a POST !!!

    Here my scan using Wireshark:

    1- using urllib and urllib2

    Hypertext Transfer Protocol
    GET / HTTP/1.1\r\n
        [Expert Info (Chat/Sequence): GET / HTTP/1.1\r\n]
            [Message: GET / HTTP/1.1\r\n]
            [Severity level: Chat]
            [Group: Sequence]
        Request Method: GET
        Request URI: /
        Request Version: HTTP/1.1
    Accept-Encoding: identity\r\n
    Host: api.apptrackr.org\r\n
    Connection: close\r\n
    User-Agent: Python-urllib/2.6\r\n
    \r\n

    2- using PyCurl

    Hypertext Transfer Protocol
    POST / HTTP/1.1\r\n
        [Expert Info (Chat/Sequence): POST / HTTP/1.1\r\n]
            [Message: POST / HTTP/1.1\r\n]
            [Severity level: Chat]
            [Group: Sequence]
        Request Method: POST
        Request URI: /
        Request Version: HTTP/1.1
    User-Agent: PycURL/7.19.5\r\n
    Host: api.website.com\r\n
    Accept: */*\r\n
    Content-Length: 365\r\n
        [Content length: 365]
    Content-Type: application/x-www-form-urlencoded\r\n
    \r\n
Line-based text data: application/x-www-form-urlencoded
    [truncated]         request=%7B%22enc_key%22%3A%22o37vOsNetKgprRE0VsBYefYViP4%2ByB3pjxfkfCYtpgiQ%2ByxONgkhhsxtqAwaXwCrrgx%2BPDuDtMRZNI1ez//4Zw%3D%3D%22%2C%22format%22%3A%22RSA_RC4_Sealed%22%2C%22profile%22%3A%22Ldn%22%2C%22request%22%3A%22bQ%2BHm/

    so the code works, but it’s not right for me because i need a POST, but i will prefer to use NOT PyCurl.
    Any idea?

    Thank you very much!!
