I'm looking at HTTP POST method to create a web page.
I'm a tad unfamiliar with it, and was looking for some explanation on how this works.
I'm simply wanting to use their seemingly simplistic page for my own server needs.
My question is this, how does this curl link really work?
curl --data-binary #audio2.flac --header 'Content-type: audio/x-flac; rate=16000' 'https://www.google.com/speech-api/v1/recognize?xjerr=1&client=chromium&pfilter=0&maxresults=1&lang="en-US"'
So I got it to work by using curl, by sending a flac file as you can see, and it responds with
this JSon stuff
{"status":0,"id":"3b7853241a0dded048f84744cc1ab896-1","hypotheses":[{"utterance":"ice cream","confidence":0.88215643}]}
Please correct me if I'm wrong:
So I believe this is a post method as it has the ? mark with it to send the name value pair.
I have no idea how they got the link https://www.google.com/speech-api/v1/recognize
to only accept POST requests without having a script name like this at the end
https://www.google.com/speech-api/v1/recognize/scriptName.pl
How do I write something to accept a post request at that given page without a .pl or .py extension? How can I put it in a certain directory on the server.
In addition for my purposes can I also send a file back to them once I process / zip?
Any ideas on how to do that?
Thanks so much for your time and generous help!
It seems that if you use --data/--data-binary/--form that the request is POSTed.
I first totally misunderstood your question and though you wanted to know how to use the interface, but you got that working.
The serverside can be achieved by multiple means, totally depending on the infrastructure and software used.
With the Webserver apache for example, you could use Rewrite or something in a HtAccess file to obfuscate/change the requested file. So looking at the extension (or the absence of it) is not helpful.
Please also see various options mentioned here
Running PHP without extension without using mod_rewrite?
or
ForceType/htaccess file extension question - extensionless files?
to see how you could achieve the same.
Only accepting POST data is then again dependant on the programming/scripting technique you employ at your server side, PHP e.g. distinguishes between multiple superglobals like $_GET and $_POST.

Simple question: I see URL queries in the format mydomain.com/myscript.php/word without question mark (?) but I don't find how to make php process it.
mydomain.com/myscript.php/word
You can use a webserver to redirect certain traffic to specific files.

I have this site:
https://acad.unoesc.edu.br/academico/login.jsp
And I want to put info in the fields values and submit then, to get the next page and navigate in that site. Thats because I want to create an android app or something like that. Im using lua in first case, with luasocket(http).
I know that the input has its names, but I dont know how to set then and send then to the server. If someone can help me with this.
Thank you.
You can use POST method with luasocket. See the official documentation and a detailed example in this SO answer.
Since you seem to be doing authentication, you'll probably need to save the cookie value returned to you as part of the login response and then pass that cookie back to the server (otherwise your subsequent requests will fail as the server will reject those requests as non-authenticated).
Since you are sending this over https, you'll need to use LuaSec, which provides ssl.https module as replacement for the http module that luasocket provides. You may check my blog post for some example of how this can be done.
I'm working with a company on lead delivery, and they sent me some info regarding a Ping Post form setup. I've built hundreds of HTML forms processed by PHP (ie. sending an email/etc), but never something that would Ping a url, then return a value. The value it returns is XML.
Here's the purpose of the process:
I send a lead (form data) using the form with a particular zip code
This company parses that info, decides if it wants to "buy" it
Returns XML saying "Approved" or "Denied"
If "approved", I then post the data, and if "denied", I can do whatever I want
What is a common PHP method for doing this? I can research the code and put something together, just need to know what structure or PHP methods would work?
Thanks in advance.
You should be looking into RESTful Web Services.
here's a few examples that might help you
http://markroland.com/blog/restful-php-api/
http://coreymaynard.com/blog/creating-a-restful-api-with-php/
I did not create these examples, just what I found on Google.
I used file_get_contents(url) to handle the posting. The url contains inputs from the HTML form added as a query string, and the response is in XML which gets handled with simplexml_load_file().
As far as I understand your question what you need is to make an HTTP POST request and parse the incoming XML data.
I would rather not use file_get_contents() on remote servers - there are some potential security issues and it was missing some features the last time I checked. I strongly recommend cURL for remote HTTP/HTTPS communication.
Depending on the API you are posting to you might be able to use the SOAPclient class, but from the look of the response you got all you need is XML parser or Simple XML.
Anyway if you just need to check if a certain keyword (like Approved or Denied) is present you can use a simple string matching like this
if(strpos($response,'<STATUS>APPROVED</STATUS')!==false){
//approved
}

I'm trying to create a restful api capable of receiving a file.
http://leejava.wordpress.com/2009/07/30/upload-file-from-rest-in-ruy-on-rail-with-json-format/
talks of how to accomplish this simply.
Not being very used to rails or curl, I don't know how to formulate my curl call.
Could anyone help me. Explain how to use curl to send a file, and how to use rails to accept and store the file.
Note.. the file is a 10 meg zip file. For testing I called it.
C:\test.zip..
I've looked at tutorials, but they all seem to be web page based. They also all degrade to resizing pictures.. Like uploading and presenting images are the same topic.
You need to know a bit about how your server-side is expecting the data. If it is a http POST with multipart/form-data (which I think it is), then this will probably help:
curl -F "fileParam=#c:\test.zip" -F "param1=xxx" -F "param2=yyyy" http://my.server/post-service
This will use curl to post form-data (including a file) to the given url with the given parameters. You need to know the parameter names for the file and the other optional parameters, and you have to obviously get the URL correct to reach your service.
Hope that helps.
Let's say, on a ColdFusion site, that the user has navigated to
http://www.example.com/sub1/
The server-side code typically used to tell you what URL the user is at, looks like:
http://#cgi.server_name##cgi.script_name#?#cgi.query_string#
however, "cgi.script_name" automatically includes the default cfm file for that folder- eg, that code, when parsed and expanded, is going to show us "http://www.example.com/sub1/index.cfm"
So, whether the user is visiting sub1/index.cfm or sub1/, the "cgi.script_name" var is going to include that "index.cfm".
The question is, how does one figure out which URL the user actually visited? This question is mostly for SEO-purposes- It's often preferable to 301 redirect "/index.cfm" to "/" to make sure there's only one URL for any piece of content- Since this is mostly for the benefit of spiders, javascript isn't an appropriate solution in this case. Also, assume one does not have access to isapi_rewrite or mod_rewrite- The question is how to achieve this within ColdFusion, specifically.
I suppose this won't be possible.
If the client requests "GET /", it will be translated by the web server to "GET /{whatever-default-file-exists-fist}" before ColdFusion even gets invoked. (This is necessary for the web server to know that ColdFusion has to be invoked in the first place!)
From ColdFusion's (or any application server's) perspective, the client requested "GET /index.cfm", and that's what you see in #CGI#.
As you've pointed out yourself, it would be possible to make a distinction by using a URL-rewriting tool. Since you specifically excluded that path, I can only say that you're out of luck here.
Not sure that it is possible using CF only, but you can make the trick using webserver's URL rewriting -- if you're using them, of course.
For Apache it can look this way. Say, we're using following mod_rewrite rule:
RewriteRule ^page/([0-9]+)/?$
index.cfm?page=$1&noindex=yes [L]
Now when we're trying to access URL http://website.com/page/10/ CGI shows:
QUERY_STRING page=10&noindex=yes
See the idea? Think same thing is possible when using IIS.
Hope this helps.
I do not think this is possible in CF. From my understanding, the webserver (Apache, IIS, etc) determines what default page to show, and requests it from CF. Therefore, CF does not know what the actual called page is.
Sergii is right that you could use URL rewrting to do this. If that is not available to you, you could use the fact that a specific page is given precedence in the list of default pages.
Let's assume that default.htm is the first page in the list of default pages. Write a generic default.htm that automatically forwards to index.cfm (or whatever). If you can adjust the list of defaults, you can have CF do a 301 redirect. If not, you can do a meta-refresh, or JS redirect, or somesuch in an HTML file.
I think this is possible.
Using GetHttpRequestData you will have access to all the HTTP headers.
Then the GET header in that should tell you what file the browser is requesting.
Try
<cfdump var="#GetHttpRequestData()#">
to see exactly what you have available to use.
Note - I don't have Coldfusion to hand to verify this.
Edit: Having done some more research it appears that GetHttpRequestData doesn't include the GET header. So this method probably won't work.
I am sure there is a way however - try dumping the CGI scope and see what you have.
If you are able to install ISAPI_rewrite (Assuming you're on IIS) - http://www.helicontech.com/isapi_rewrite/
It will insert a variable x-rewrite-url into the GetHttpRequestData() result structure which will either have / or /index.cfm depending on which URL was visited.
