google app engine - HttpClient not POST-ing data to backend server- javascript -


i trying post data web server (google app engine) windows phone using javascript. request reaching server, values going null.

the post request:

var payload = '{"type":"a","make":"b","model":"c","year":"1990"}'; //uri var uri = new windows.foundation.uri(uristring); //ihttpclient var stringcontent = windows.web.http.httpstringcontent(payload, windows.storage.streams.unicodeencoding.utf8, 'application/json'); httpclient.postasync(new windows.foundation.uri(uri), stringcontent);

if make properties required=false null. if make required=true badvalueerror: entity has uninitialized properties: vehicle_type, make, model, year

class vehicle(ndb.model): vehicle_type = ndb.stringproperty(required=false) make = ndb.stringproperty(required=false) model = ndb.stringproperty(required=false) year = ndb.stringproperty(required=false)

the goal have new vehicle added datastore such:

{"keys": 6212341628665856, "make": "dodge", "vehicle_type": "suv", "model": "caravan", "year": "1999"}

if use curl call server works fine:

curl -x post --data-urlencode "type=suv" --data-urlencode "make=dodge" --data-urlencode "model=caravan" --data-urlencode "year=1999" myurl

all appreciated

try use logging module , see whether values receive in backend correct or not.

first of import logging module.

import logging

second thing, need use logging module see whether values in backend upto mark. suppose have webapp2.requesthandler as

import webapp2  class getcarinfo(webapp2.requesthandler):  def get(self): #or post    #show values in gae sdk console   logging.info(self.request)    #or logging.info(self.request.get('<your payload object key>'))    #your entity creation(ndb put) code here.   app = webapp2.wsgiapplication([     ('/add_car_info', getcarinfo) ], debug=true)

once able see correct info being passed javascript client. can proceed further else need figure out what's wrong javascript client(ajax request) or payload passing.

hope you.!

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac

apache - How do I stop my index.php being run twice for every user -
