How do I access the data sent to my server using BaseHTTPRequestHandler?
basehttprequesthandler, post, python, python-3.x
Solution
Give this a try. I stole it from an answer to another question
def do_POST(self):
ctype, pdict = cgi.parse_header(self.headers.getheader('content-type'))
if ctype == 'multipart/form-data':
postvars = cgi.parse_multipart(self.rfile, pdict)
elif ctype == 'application/x-www-form-urlencoded':
length = int(self.headers.getheader('content-length'))
postvars = cgi.parse_qs(self.rfile.read(length), keep_blank_values=1)
else:
postvars = {}
print(postvars.get("listName", "didn't find it"))
Problem
I'm a newbie to Python (using v3.3) and web programing and I've been struggling with a problem all night. I'm issuing a POST call to my server and sending it some data as follows: ``` DATA = {"listName":"Test list","listDesc":"A test list with test stuff in it.","refreshMode":"Replace","DBKey":"1","UserDisplaySeq":"1"} DATA = json.dumps(DATA) METHOD = "POST" DATA = DATA.encode("utf-8") params = "account_id=acct 2" try: URL = "http://localhost:8080/lists?" + quote_plus(params) request = urllib.request.Request(url=URL,data=DATA,method=METHOD) response = urllib.request.urlopen(request) ... ``` I also have a request handler coded as follows (there are lot of print statements in here for debugging purposes): ``` class MyHandler(BaseHTTPRequestHandler): ... def do_POST(self): length = int(self.headers['Content-Length']) print("HEADERS: ", self.headers) print (str(length)) print(self.rfile) post_data = urllib.parse.parse_qs(self.rfile.read(length).decode('utf-8')) print(post_data) ``` This prints the following result to the console: ``` Starting thread started httpserver... HEADERS: Accept-Encoding: identity User-Agent: Python-urllib/3.3 Content-Length: 138 Content-Type: application/x-www-form-urlencoded Host: localhost:8080 Connection: close 138 <_io.BufferedReader name=404> {} ``` My questions: 1) In the server (do_POST), how do I access the data I think I'm sending with my request (i.e. {"listName":"Test list","listDesc":"A test...)? 2) Is my request even sending the data in the first place? 3) Is there a place where this is documented in novice-accessible terms?
