  • POST with curl without sending data

    - by Marcus
    Is there a way to use curl to send a POST request without sending any data? We usually post like: curl --data @C:\mydata.txt http://1.2.3.4/myapi If you omit the --data you are doing a GET. How can you omit it and still do a POST?

  • iOS: RestKit loadObject & send params

    - by Alon Amir
    using loadObjectAtResourcePath, on GET method, doesn't include my parameters on the requests. for example, i send: [RKObjectManager objectManagerWithBaseURL:@"http://something/ws"]; [[RKObjectManager sharedManager] loadObjectsAtResourcePath:@"/res" delegate:self block:^(RKObjectLoader *loader) { NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys: @"val", @"param1", nil]; loader.params = [RKParams paramsWithDictionary:dict]; }]; the final url request doesn't include the "?param1=val" part - why is that?

  • Chrome extension - Localstorage not working

    - by Bjarki Jonasson
    I'm writing a Chrome extension that uses a content script to modify certain parts of a website. The content script worked fine until I tried to add an options page to my extension. Right now I'm using an options.html file to save user preferences to localstorage, as you can see here: <html> <head><title>Options</title></head> <script type="text/javascript"> function save_options() { var select = document.getElementById("width"); var width = select.children[select.selectedIndex].value; localStorage["site_width"] = width; } function restore_options() { var fwidth = localStorage["site_width"]; if (!fwidth) { return; } var select = document.getElementById("width"); for (var i = 0; i < select.children.length; i++) { var child = select.children[i]; if (child.value == fwidth) { child.selected = "true"; break; } } } </script> <body onload="restore_options()"> Width: <select id="width"> <option value="100%">100%</option> <option value="90%">90%</option> <option value="80%">80%</option> <option value="70%">70%</option> </select> <br> <button onclick="save_options()">Save</button> </body> </html> I also have a background.html file to handle the communication between the content script and the localstorage: <html> <script type="text/javascript"> chrome.extension.onRequest.addListener(function(request, sender, sendResponse) { if (request.method == "siteWidth") sendResponse({status: localStorage["site_width"]}); else sendResponse({}); }); </script> </html> Then there's the actual content script that looks like this: var Width; chrome.extension.sendRequest({method: "siteWidth"}, function(response) { width = response.status; }); None of that code actually works. It looks solid enough to me but I'm not a very experienced programmer so I might be wrong. Could someone explain localstorage to me in layman's terms?

  • how to fix protocol violation in c#

    - by Jeremy Styers
    I have a c# "client" and a Java "server". The java server has a wsdl it serves to the client. So far it works for c# to make a request for the server to perform a soap action. My server gets the soap request executes the method and tries to return the result back to the client. When I send the response to c# however, I get "The server committed a protocol violation. Section=ResponseStatusLine". I have spent all day trying to fix this and have come up with nothing that works. If I explain what i did, this post would be very long, so I'll keep it brief. i Googled for hours and everything tells me my "response line" is correct. I tried shutting down Skype, rearranging the response line, adding things, taking things away, etc, etc. All to no avail. This is for a class assignment so no, I can not use apis to help. I must do everything manually on the server side. That means parsing by hand, creating the soap response and the http response by hand. Just thought you'd like to know that before you say to use something that does it for me. I even tried making sure my server was sending the correct header by creating a java client that "mimicked" the c# one so I could see what the server returned. However, it's returning exactly what i told it to send. I tried telling my java client to do the same thing but to an actuall running c# service, to see what a real service returns, and it returned basically the same thing. To be safe, I copied it's response and tried sending it to the c# client and it still threw the error. Can anyone help? I've tried all i can think of, including adding the useUnsafeHeaderParsing to my app config. Nothing is working though. I send it exactly what a real service sends it and it yells at me. I send it what i want and it yells. I'm sending this: "200 OK HTTP/1.0\r\n" + "Content-Length: 201\r\n" + "Cache-Control: private\r\n" + "Content-Type: text/xml; charset=utf-8\r\n\r\n";

  • How to handle redirects while parsing HTML? - Python

    - by RadiantHex
    Hi folks, I'm trying to submit a few forms through a Python script, I'm using the mechanized library. This is so I can implement a temporary API. The problem is that before after submission a blank page is returned informing that the request is being processed, after a few seconds the page is redirected to the final page. I understand if it might sound a bit generic, but I'm not sure what is going on. :) Any ideas?

  • How can I create and use a web service in public but still restrict its use to only my app?

    - by Glenn
    I'm creating a web service with create/update/delete calls. But for now I'd like to restrict use of it on my own web app and no other clients. How can I have clear text javascript code that makes these calls but still be confident the credentials won't be used elsewhere? My idea is to use server side generated nonces for each request. But I am open to different ideas you guys may have. Thanks.

  • How do I use rest-client for ruby to post an image?

    - by Angela
    I am trying to find a way to use the Postful API and I need to post an image in the body of the request. I am trying to use rest-client (but am open to other ways): This is how I am trying to use it after looking at the restclient.rb file but I'm still not clear: class ContactPostfulsController < ApplicationController require 'rest_client' RestClient.post 'http://www.postful.com/service/upload', 'the actual image...?', :content_type => 'application/octet-stream' end

  • Jquery $.post and PHP - Prevent the ability to use script outside of main website.

    - by Tim
    I have a PHP script setup using Jquery $.post which would return a response or do an action within the targeted .php file within $.post. Eg. My page has a form where you type in your Name. Once you hit the submit form button, $.post is called and sends the entered Name field value into "mywebsite.xyz/folder/ajaxscript.php" If a user was to visit "mywebsite.xyz/folder/ajaxscript.php" directly and somehow POST the data to the script, the script would return a response / do an action, based on the submitted POST data. The problem is, I don't want others to be able to periodically "call" an action or request a response from my website without using the website directly. Theoretically, right now you could determine what Name values my website allows without even visiting it, or you could call an action without going through the website, by simply visiting "mywebsite.xyz/folder/ajaxscript.php" So, what measures can I take to prevent this from happening? So far my idea is to ensure that it is a $_POST and not a $_GET - so they cannot manually enter it into the browser, but they could still post data to the script... Another measure is to apply a session key that expires, and is only valid for X amount of visits until they revisit the website. ~ Or, just have a daily "code" that changes and they'd need to grab this code from the website each day to keep their direct access to the script working (eg. I pass the daily "code" into each post request. I then check that code matches in the ajax php script.) However, even with these meaures, they will STILL have access to the scripts so long as they know how to POST the data, and also get the new code each day. Also, having a daily code requirement will cause issues when visiting the site at midnight (12:00am) as the code will change and the script will break for someone who is on the website trying to call the script, with the invalid code being passed still. I have attempted using .htaccess however using: order allow,deny deny from all Prevents legitimate access, and I'd have to add an exception so the website's IP is allowed to access it.. which is a hassle to update I think. Although, if it's the only legitimate solution I guess I'll have to. If I need to be more clear please let me know.
