Tasker App: Why my HTTP POST is not sending parameters?

I'm making a simple HTTP POST request using Tasker app, it's working fine but somehow it's not sending my arguments. HTTP GET is working fine. What am I doing wrong?
The only thing the server does is JSON stringify all received parameters and return them like: Text: { parameters }
HTTP GET is working:
HTTP POST works, it returns the response "text: {}" but doesn't return any parameter:
Now sometimes it shows "Bad Request Error 400"
I've tested it with another server and this issue persists...
Here's a fiddle to send get and post requests to the same server and both work.
I've exported my task as xml for you to test: You can download it here
Thanks in advance guys!

I have done a little testing with what you have supplied. It appears that your post parameters are making it to the server but %HTTPR is not getting populated. The Tasker documentation says that this variable will be populated if the response is "text-based", but this does not seem to be the case. I may not know what Tasker considers to be "text-based", but I have tried "text/plain" and "text/html" with no luck.
The work-around that I have come up with is to put the response into a file using the "Output File" field of the post task. (Leave "Content Type" blank or this won't work.) You can then read the file into a variable and do what you need to.
This is either a defect in Tasker, incorrect documentation, or just a misunderstanding of what it takes to make it work. This work-around, however, will get you what you need.
Here is a link to a GitHub repository with the updated task export. You may need to change the output file name/location to work with your device.
Update:
Since I posted the above solution, I have run across a Tasker plugin called "RESTask for Tasker". Evidently, Tasker has enough issues with HTML requests that a separate plugin was needed. I have tested this plugin with POST and it does work, so this is another way to go. The plugin is available on the Google Play store.

Fehler (error) 6 - the requested item could not be loaded

Currently I'm developing android application that needs to connect itself to REST API. It is crucial for my app to access API whenever connection is possible (mobile data/wifi).
But when testing my app something extremely weird happened. Application works as expected almost all the time, but when on VipMobile operator (Austria telekom group) I cannot connect to API.
At first I didn't get it, error was too unreadable. It says
j u fehler6 the requested item could not be loaded & wrong mime type
There are a lot of unprintable chars in that message too. When i figured out that it is operator fault i tried to copy link to my API and got this.
What could that possibly be? Can anyone point me in any direction, I cannot publish application as long as there are those ridickulous errors.

This happens when the user is on 3g connection. Some mobile operators intercept clients request and if the Content-Type is not good, or not defined they display page like this. This happens also to vipmobile operator in Serbia.
Try to add right content-type to response headers on your server side.
Try to put for example Content-Type:text/plain;charset=utf-8 to headers

Google Safe Browsing API v2 sample Implementation Android

I am trying to implement a Sample application in Android which gets the malware and phishing list from safe Browsing API and checks the authenticity of URL, this is client side method, but I am constantly getting 400 (Bad Request) as response code when I am trying to hit the URL.
Searched throughout the internet but couldn't get any sample working code.
Even on Developer's Guide page https://developers.google.com/safe-browsing/developers_guide_v2 it is not mentioned how to send the list name correctly in POST request for downloading or updating.
Please help me by providing the correct procedure of how to send list name (if code snippet can be posted, it would be great as I am new to Android.)

Check out that request should end with '\n'. It is common to ignore this. I hope it helps.

What is Apache-HttpClient/UNAVAILABLE error (Android, Google App Engine)?

I am confronting myself with a problem that I do not know how to interpret. I am doing a project using Android and Google App Engine. When I am trying to save information in Google App Engine's Big Table, directly from the servlet (hardcoded) - the save is performed with no problem. But when I am trying to save data from my Android device, the save is not performed and the log indicates Apache-HttpClient/UNAVAILABLE error. To be more specific:
405 55ms 0kb Apache-HttpClient/UNAVAILABLE (java 1.4)
82.155.246.249 - - [10/Jun/2013:05:20:59 -0700] "POST /servletnamehere HTTP/1.1" 405 306 - "Apache-HttpClient/UNAVAILABLE (java 1.4)" "appnamehere.appspot.com" ms=56 cpu_ms=21 cpm_usd=0.000034 app_engine_release=1.8.0 instance=00c61b117cede3f754aa1ece730dc88287a20199
I have seen that 405 HTTP error appears in the context of a POST method ( "405 errors often arise with the POST method. You may be trying to introduce some kind of input form on the Web site, but not all ISPs allow the POST method necessary to process the form." ) => indeed, I am trying to perform add (the object is a JPA Entity) in the database using a POST method. The data I am receiving from my Android device is serialized, through an input stream (in my case, working with JSON is not an option, these are the specifications).
Also, 306 HTTP error reffers to switch proxy. While the porevious error might be a bit intuitive, this one is beyond my student knowledge.
I have followed the instructions of this tutorial (http://trumpy.cs.elon.edu/joel/sigcse2011/), which is indeed what I need, but I really cannot figure out what I did wrong. I took again the procedure, stept by step, but I don't see the flaw.
Any help will be indeed appreciated. If I should post some code, I'll gladly do it.
Best wishes,
Cropcircles
LATER EDIT:
Now I get 417 HTTP error expectation failed. I have seen that I am supposed to set a certain parameter on false, but this workaround was available only for .NET. Is there anyone who knows what's the correspondent of the following, in Java? I am really really confused.
<system.net>
<settings>
<servicePointManager expect100Continue="false" />
</settings>
</system.net>

This is not an answer, but is too long for a comment and may be helpful, so here goes...
First, it's hard to tell what's going on here because there is limited info. Try to post more of the logging either on the client or on the server. Go to the server console and get more info, for instance, or add debugging in the client. I'd start by trying to make the POST from a debug/testing tool like hurl.it: http://www.hurl.it/ (hurl is a nice web front end to a command line HTTP client named curl, see curl itself if you want a more advanced peek). That way you can test and poke around and make SURE your server side works as you expect with a generic client. Then build other clients (like Android).
Second, "Apache-HttpClient/UNAVAILABLE" is not an error, it's just the user-agent String -- so ignore that part. (UNAVAILABLE is where the version typically is, but some impls don't have access to the version sometimes, it seems.)
Third, the 405 response code IS an error, it means POST is not allowed at the server you are trying to POST to. That can either be because POST is not allowed at all on said server, or you're violating some security policy (such as same origin).
If it's AppEngine, first check the APP you are using and make sure it supports POST (look for info on how to do POST at AppEngine to solve, for instance: google app engine: 405 method not allowed). When you say you can do it directly from a "servlet," do you mean that a POST from a different client works? (Servlet is a server side technology, so that's a little confusing.) If so then make sure your Android app is doing the client part the same way to the same host (multipart vs urlencoded, etc).
For a little more on the security stuff, which could be involved, see this post: Google App Engine + jQuery Ajax = 405 Method Not Allowed.

I've had the same trouble and in my case It was an error due to no write permission on server side area.
I was following an android test to write on a file a value transmitted in async way via POST method.
Apache received the POST request but was not able to write the data on the file due to security permission on it.

Android: Fail to retrieving a tag value of the EWS response

I am hitting my Exchange server using (EWS+Basic Authentication). I could authenticate and hit my services with these Request GetItem (E-mail Message),SyncFolderItems and few other and getting the response successfully. I could parse the SyncFolderItems response to get basic info abt the Mail Items (Like Subject,To,From,HasAttachments etc.). But when i hit the GetItem request i am receiving a response but i couldnt get the Mail item Body (i.e, the Message). Is it any tutorial to do this. I am using XMLPullParser..
The response might be look like this . Plz guide me on this

I've used JWebServices for Exchange (Android version) several times. It's not free but accomplished what I needed. You should try the API to see if they get correct Body to see if your application fails or body is empty.

Thanks for ur valuable replies.. I found the data (values) that i stored from the saxparser is not complete. So only i couldnt get the html content properly in the webview.
i used the following link as reference and used the string buffer to resolve this issue.
Thx
