Ciao, ho alcuni problemi per effettuare l'upload da un programma in python a una pagina php tramite il protocollo http, in python vorrei fare la richiesta mentre in php vorrei fare l'upload vero e proprio:
(Ho trovato poco in giro)
Python
La pagina php funziona se faccio l'upload semplice con il classico form html, mentre provando così, ottengo:codice:import httplib, mimetypes,os def post_multipart(host, selector): content_type, body = encode_multipart_formdata() h = httplib.HTTPConnection(host) headers = { 'User-Agent': 'Prova upload', 'Content-Type': content_type } h.request('POST', selector, body, headers) res = h.getresponse() return res.status, res.reason, res.read() def encode_multipart_formdata(): BOUNDARY = '1484868717354' CRLF = '\r\n' L = [] fields = "" key = "name" value = "" filename= "logo2.png" handle = open (filename,'r') value += handle.read() handle.close() filesize = os.stat(filename).st_size L.append('Content-Disposition: form-data; boundary="-----------------------------"' + BOUNDARY) L.append('Content-Length: %s' % (filesize)) L.append('') L.append('-----------------------------' + BOUNDARY) L.append('Content-Disposition: form-data; name="%s"; filename="%s"' % (key, filename)) L.append('Content-Type: %s' % get_content_type(filename)) L.append('') L.append(value) L.append('-----------------------------' + BOUNDARY + '--') body = CRLF.join(L) content_type = 'multipart/form-data; boundary=%s' % BOUNDARY return content_type, body def get_content_type(filename): return mimetypes.guess_type(filename)[0] or 'application/octet-stream' print post_multipart("host","upload1.php")
codice:(400, 'Bad Request', '<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">\n<html><head>\n<title>400 Bad Request</title>\n</head><body>\n<h1>Bad Request</h1>\n Your browser sent a request that this server could not understand. \n</p>\n Additionally, a 403 Forbidden\nerror was encountered while trying to use an ErrorDocument to handle the request.</p>\n</body></html>\n')
Per conoscere il modo in cui opera il protocollo http, ho fatto una richiesta con il browser a una specie di server in php che ho programmato, ottenendo:
-Firefox
name="upload" è il name del tasto submitcodice:POST / HTTP/1.1 Host: localhost:8082 User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; it; rv:1.8.1.8) Gecko/20071008 Firefox/2.0.0.8 Accept: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5 Accept-Language: it-it,it;q=0.8,en-us;q=0.5,en;q=0.3 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 300 Connection: keep-alive Referer: http://localhost:85/upload.php Content-Type: multipart/form-data; boundary=---------------------------1484868717354 Content-Length: 23350 -----------------------------1484868717354 Content-Disposition: form-data; name="name"; filename="640321.jpg" Content-Type: image/jpeg i caratteri che formano il file -----------------------------1484868717354 Content-Disposition: form-data; name="upload" Carica file -----------------------------1484868717354--
mentre name="name" dovrebbe essere $_FILES['name']
-con il mio in python
Spero qualcuno possa aiutarmi, non so dove sbaglio nella richiesta.codice:POST upload1.php HTTP/1.1 Host: localhost:8082 Accept-Encoding: identity Content-Length: 59970 Content-Type: multipart/form-data; boundary=1484868717354 User-Agent: Prova upload Content-Disposition: form-data; boundary="-----------------------------"1484868717354 Content-Length: "59672" -----------------------------1484868717354 Content-Disposition: form-data; name="name"; filename="logo2.png" Content-Type: image/png i caratteri che formano il file..... -----------------------------1484868717354--
Penso che la sezione sia adatta.
