  • Programmatically Download Image to Desktop from Remote App with Ruby?

    - by viatropos
    I was thinking about making a little crop/resize batch processor online, and wanted to know if there was a way for me to do the following: upload image and specify dimensions click "process" and app resizes image image downloads automatically to wherever it was I uploaded it (say from my desktop), but with a new name (based on the time for example). This would make it so I could host a free image processor that never stored any data other than tempfiles. Is that possible? Something like Rails' send_file method, but I'm using Sinatra and am looking for something in pure ruby.

  • Google Analytics cookies

    - by wokena
    My problem: I erased all cookies from my computer. I sent Post request to the X server log and sent me a "normal" Set-Cookie with its parameters, but then somehow it will send request for Google Analytics (GA), in which the "strange" header (utma, utmac, utmcn ...). This happens when I send request in browser. But when I pass a request to login from my program (I programm in Ruby), so my server will return 302 Found, but no request to the GA sends. And I just need these headers ...

  • Using GET instead of POST to delete data behind authenticated pages

    - by Matt Spradley
    I know you should use POST whenever data will be modified on a public website. There are several reasons including the fact that search engines will follow all the links and modify the data. My question is do you think it is OK to use GET behind authenticated pages in something like an admin interface? One example would be a list of products with a delete link on each row. Since the only way to get to the page is if you are logged in, is there any harm in just using a link with the product ID in the query string?

  • PHP, Ajax, and the lifespan of the request

    - by Dave
    I was wondering about the lifespan of a PHP script when called via Ajax. Assume that there is a long-running (i.e. 30 seconds) PHP script on a server and that page is loaded via Ajax. Before the script completes, the user closes the browser. Does the script continue running to completion, is it terminated, or is this a function of the server itself (I'm running Apache fwiw). Thanks for any help.

  • Mirror a website with httrack while executing javascript

    - by Martin
    I want do save a mirror of www.youtube.com/tv. I obviously do not want to save the videos. I want the code running the website in a local copy, everything else can stay remote. The code I want is mainly contained in 2 files: live.js and app-prod.js. I tried using httrack. I have issue parsing the javascript to load anything past the first file: live.js. The %P parameter does not help. httrack www.youtube.com/tv +* -r6 --mirror -%P -j It doesn't go further than live.js because some javascript needs to be executed to load the next file. I know I can do this manually with any browser. I want to automate the process. Is httrack able to do this by itself? If yes, how?

  • Using PHP to get the source code of a URL I must be logged in to reach

    - by Maxwell
    I am trying to write a PHP script that will get the source code of a page in my Amazon account. However, to reach that page, I must be logged in. From what I understand, I should be able to accomplish this by posting the correct request headers, and then capturing the HTML response. Is that correct? If so, I'd really appreciate it if someone could explain to me how exactly I would do this. If it's not right, I'd love to hear the correct way of doing it! I've used Firebug to get the request and response headers I need. It's just a matter of what to do with them now. I read elsewhere on this site that you can't send a request with the PHP post method, and that perhaps using cURL is the way to go. I really know nothing about cURL, so the more info the better. Also, feel free to point me to some useful tutorials on this topic. Thanks! Max

  • Apache basic auth, mod_authn_dbd and password salt

    - by Cristian Vrabie
    Using Apache mod_auth_basic and mod_authn_dbd you can authenticate a user by looking up that user's password in the database. I see that working if the password is held in clear, but what if we use a random string as a salt (also stored in the database) then store the hash of the concatenation? mod_authn_dbd requires you to specify a query to select that password not to decide if the user is authenticated of not. So you cannot use that query to concatenate the user provided password with the salt then compare with the stored hash. AuthDBDUserRealmQuery "SELECT password FROM authn WHERE user = %s AND realm = %s" Is there a way to make this work?

  • Should I log my website's 404 errors?

    - by Ivan Zlatanov
    I have an ASP.NET website, but this question isn't really about technology, it is rather about practice. Should we log our 404 errors? My reasoning: This is a potential vulnerable point because a simple unfriendly user may fill up your hard drive in no time just by requesting wrong URLs! Some browsers often request resources up front - like for example favicon.ico, even if its not there. This is really annoying. But really I would like to know about a broken link if there exists one in my websites. Should I depend on the URL referrer? The problem with the URL referrer is that I cannot distinguish my internal redirect which may be broken with an unfriendly one from outside. What does the practice suggest?

  • 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?

  • Javascript XMLHttpRequest Post method

    - by user535617
    Hey So I have a question about posting using an XMLHttpRequest. In theory, if I am to post a username and password to an https domain (which I have yet to get working, unfortunately) would the responseText then change to the next website, or should the text fields become filled in? What normally happens is you navigate to this page via browser, enter a username and password, and it uses a POST method when the submit button is clicked, doing some authentication under the hood and returning a different page. I feel like maybe the responseText should even stay exactly the same (which is what happens now), but I don't know as I have no experience with this kind of thing. this.requests[1].open("POST", "https://" + this.address, true); var query = "target=%2Fcgi-bin%2FStatusConfig.cgi%3FPage%3Dindex&userfile=&username=user&password=pass&log+in=Log+in"; this.requests[1].setRequestHeader("Content-Type", "application/x-www-form-urlencoded"); this.requests[1].setRequestHeader("Content-length", query.length); this.requests[1].setRequestHeader("Keep-Alive", 115); this.requests[1].setRequestHeader("Connection", "keep-alive"); this.requests[1].setRequestHeader("Host", this.address); this.requests[1].send(query); this.requests[1].onreadystatechange = onReadyStateChange1; Then basically onReadyStateChange1 displays the responseText when ready. Any light that could be shed on what SHOULD be happening with the post and responseText would be very appreciated. As would any advice in getting the new, logged into page. For further clarification, what I'm trying to do is log in and then return the new page, because the login page displays only log in information/functionality and the page after logging in has a lot of relevant information. I'm not trying to check the credentials as much as I'm trying to get it (the script) to log in so it can access the next page. Granted, the credentials will have to be valid for that. Thanks all.

  • How to embed cover art in an MP3 file so that the iPhone player displays it when downloaded

    - by Paul Dixon
    I want to be able to provide a URL to a music track, and when that track is played on an iPhone, to show the cover art. I've tried embedding the cover art as an ID3 v2.3 tag, and while desktop players like VLC and Windows Media Player can see it, it seems the iPhone doesn't. Is this possible? Does anyone know of a way to achieve this - preferably a method which can be automated? Edit: this may not be possible - even if I add cover art with iTunes, the resulting file will still not have the coverart displayed when played as a download :(

  • cURL + HTTP_POST, keep getting 500 error. Has no idea?

    - by mysqllearner
    Okay, I want to make a HTTP_POST using cURL to a SSL site. I already imported the certificate to my server. This is my code: $url = "https://www.xxx.xxx"; $post = "";# all data that going to send $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, $post); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE); curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0'); $exe = curl_exec($ch); $getInfo = curl_getinfo($ch); if ($exe === false) { $output = "Error in sending"; if (curl_error($ch)){ $output .= "\n". curl_error($ch); } } else if($geInfo['http_code'] != 777){ $output = "No data returned. Error: " . $geInfo['http_code']; if (curl_error($ch)){ $output .= "\n". curl_error($ch); } } curl_close($c); echo $output; It keep returned "500". Based on w3schools, 500 means Internal Server Error. Is my server having problem? How to solve/troubleshoot this?

    I want the user to submit an answer to a question, then upon submission be redirected back to the page where they asked the question and I can't seem to get this to work: if (!isset($_POST['answer']) && !isset($_POST['verse'])) { echo "Please fill out form."; } elseif (!isset($_POST['answer']) || !isset($_POST['verse'])) { echo "one field left blank"; } else { $user->submitAnswer($question_id); header("Location: welcome.php?question_id=$question_id"); exit; } What am I doing wrong?

  • Having trouble reading XML file from Windows server. Works on Linux

    - by DuFF14
    I'm parsing an XML file in an android app. My success varies depending upon where the file is hosted. After hosting the file on 4 different servers (2 Linux, 2 Windows), I discovered that when the xml is hosted on a Linux server, the app works. When it's hosted on a Windows server, I am unable to parse correctly. Instead of reading the expected xml tags, it reads HTML tags (, , , etc). I'm not sure why it doesn't work on Windows servers, or if that is even the issue and not just a coincidence. Any help is appreciated. Thanks. Here is my code: private void getXmlData() { HttpClient httpclient = new DefaultHttpClient(); String url = XML_URL; HttpPost httppost = new HttpPost(url); HttpResponse response = httpclient.execute(httppost); SaxParser saxParser = new SaxParser(response); parsedXML = saxParser.parse(); }

    In relation to an earlier question I'm looking for an alternative way to send an order from my website to the division in my company that processes the order. Currently I use PHP mail(), but frequently this gives problems. Big delays occur. Are there alternatives to PHP mail() that pushes the order to my company? So I prefer not to poll the website.
