POPython socket recv (client-side)
text
Body
copied!<p>i have to connect to an api via socket and send / recv some data. the company send me a php-example-file with this code for reading data from the socket:</p> <pre><code>function readAnswer() { $size = fgets($this->socketPtr, 64); $answer = ""; $readed = 0; while($readed < $size) { $part = fread($this->socketPtr, $size - $readed); $readed += strlen($part); $answer .= $part; } return $answer; } </code></pre> <p>This works for me. But in python i get from times to times an error. not everything from the socket is recv. my python try looks like this:</p> <pre><code>def read_answer(self,the_socket,timeout=0.5): the_socket.setblocking(0) total_data=[] data='' begin=time.time() while 1: if total_data and time.time()-begin > timeout: break elif time.time()-begin > timeout*2: break try: data = the_socket.recv(8192) if data: total_data.append(data) begin=time.time() else: time.sleep(0.1) except: pass return ''.join(total_data) </code></pre> <p>i recv data as a dict / array. and from time to time i only get a int (msg length i think) so what would be a better way to read the data from socket. ah the api sends the data in a correct way, i checked this. it's only this little function ;(</p> <p>After using the code below (thanks falsetru) and added a readed=len(data) i run into another problem: this is the working php code:</p> <pre><code> function _parse_answer($answerData) { $result = array(); $lines = explode("\n", $answerData); $data = explode("&", $lines[0]); foreach($data as $piece) { $keyval = explode("=", $piece, 2); $result[$keyval[0]] = $keyval[1]; } for($i=1;$i<count($lines);$i++) { $result["csv"][]=$lines[$i]; } return $result; } </code></pre> <p>and this my crappy python code:</p> <pre><code>def parse_answer(self,data): #print "dd_demo_api: answer: (%s)" % (data) if data: result = {} lines = data.split("\n") index_list = 0 if len(lines) == 1: index_list = 0 else: index_list = 1 pieces = lines[index_list].split("&") for x in pieces: keyval = x.split("=") result[keyval[0]] = keyval[1] iterlines = iter(lines) next(iterlines) next(iterlines) count = 1 result["csv"] = {} for x in iterlines: result["csv"][count] = x.split(";") return result else: return 0 </code></pre> <p>i think here is some optimization required? ;(</p>
