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 want to test a set of ruby-on-rails applications. Specifically, I want to trigger all possible GET/POST requests available. I am considering using some web crawler-like tool, which could (recursively) send requests to my web server, get responses, and parse the response HTML file to get all possible "href tags", "form submission buttons", etc.
Essentially I want to see the performance of these web applications and get some logs of things like what are the request routes, parameters, database accesses, queries, transactions, etc.
Sending GET requests is relatively easy to handle, I would need to simply parse the HTML response and extract the href attributes of all anchors. However, I don't know how to handle those POST requests; they would require me to fill in all these parameter fields included in the form fields. I am wondering if there exist some tools doing such work. Or some tools I can easily modify (not too much) code to achieve my functionality?
Thanks a lot.
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 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.
My issue is that I do not know how to process an incoming request without knowing the URL that the post message is coming from.
The Vend API that I am trying to integrate with sends a post message to my URL with the following information:
"The POST body will include a field named payload. This field contains
a JSON encoded object with details of the object that caused the
hooked event. Other form fields (such as environment or domain_prefix)
may be present, but are not guaranteed to be.
The payload objects you’ll find in webhook requests are now the same
as those you’ll receive from the newer parts of the API marked as
version 1.0 or higher. So, for example, the product webhook should
give you a product payload that’s the same as if you requested
/api/1.0/product/{product_id}."
http://docs.vendhq.com/webhooks.html (here is the link for more details)
I'm fairly new to ASP MVC and I'm having trouble figuring out the best way to go forth. I need to eventually map the incoming name value pairs to my model.
Any help would be greatly appreciated.
When you said you don't know the URL that the post message is coming from, I think you mean that you don't know the format of the URL (path and parameters) that the webhook is being posted to. The only things your MVC app needs to know in order to process the request are the names of the post parameters, which in this case is a single parameter named payload that contains a JSON string according to the snippet you included from the documentation.
There are several ways for you to get this data. One of the most simple is to take advantage of ASP.NET MVC's automatic mapping of POST parameters to controller action method parameters:
public ActionResult MyActionMethod(string payload)
{
// 'payload' will be automatically populated with the json string from the POST payload
}
Of course you now have to parse the json payload which you can do in several ways using the .NET framework or with any number of 3rd party libraries.
I have zero experience with Web API and JSON. My requirements are to create a service (I'm using Web API for this) that will accept MIME Encoded JSON data. The service will take that data, insert it into a database, and return the primary key value back to the client.
My hang-up is being able to know where to even start with this. A couple of questions that I have are:
When the device sends the JSON data, how will the service "accept" it? Meaning, what's being passed to the service isn't an URL that we commonly see with MVC (/Controller/Action/ID) which then invokes the Action Method. So, how will the service know what to invoke if I'm passing raw JSON data?
How would I test this if I don't have a device that sends the JSON data yet? Would I manually invoke an AJAX call and call that particular action method and pass in the JSON data that way?
I apologize for the seemingly elementary questions.
Thanks.
When you call a WebAPI-method you still have to specify the endpoint:
Example:
PUT /api/people
MVC knows from that that it should call the put-method on the PeopleController.
You can send raw JSON-data to test it. A good tool for that is HttpFiddler: http://fiddler2.com/
As for where to start, try to create a basic WebAPI-project with visual studio, it will include some samples and you can get going from that. If you run into wall, you can come back here
