I have developed a web service with php, PDO and nusoap. I use json_encode() function to returns an array as a result of my web service functions. In the array there are persian characters and result is like:
\u062c\u0627\u0645 \u0645\u0644\u062a\u0647\u0627\u06cc \u0627\u0631\u0648\u067e\u0627
I also used JSON_UNESCAPED_UNICODE inside json_encode() and the result is:

How can I solve my problem to show persian characters correctly?

My 4D database has a method that calls an external application to make an HTTP request to an API site, e.g. https://somewhere.com/api/?key=somekey¶m=someparam. The request returns a JSON response. However, the external application only returns a call success or fail. I am not able to extract the JSON response.
My 4D database is still in version 12 and have no plans to migrate yet to latest version. Is there any way for me to make an HTTP request and get the JSON response? I was thinking of using the built-in PHP engine and make cURL call. Has anybody done this in 4D?
I recommend using Keisuke Miyako's OAuth plugin. https://github.com/miyako/4d-plugin-oauth. It comes with a cURL library and a JSON parsing library. I use it to pull JSON data from an api source. It looks like he's depricated the plug-in but has links to the separate components.
http://sources.4d.com/trac/4d_keisuke/wiki/Plugins/
ARRAY LONGINT($optionNames;0)
ARRAY TEXT($optionValues;0)
C_BLOB($inData;$outData)
$url:="https://api.atsomewhere.com/blahblah"
$error:=cURL ($url;$optionNames;$optionValues;$inData;$outData)
If ($error=0)
$jsonText:=BLOB to text($outData;UTF8 text without length)
$root:=JSON Parse text ($jsonText)
JSON GET CHILD NODES ($root;$nodes;$types;$names)
$node:=JSON Get child by name ($root;"Success";JSON_CASE_INSENSITIVE)
$status:=JSON Get bool ($node)
If ($status=1)
$ResponseRoot:=JSON Get child by name ($root;"Response";JSON_CASE_INSENSITIVE)
$node1:=JSON Get child by name ($ResponseRoot;"SourceId";JSON_CASE_INSENSITIVE)
$node2:=JSON Get child by name ($ResponseRoot;"SourceName";JSON_CASE_INSENSITIVE)
$output1:=JSON Get text ($node1)
$output2:=JSON Get text ($node2)
End if
End if
4D v12 has built-in support for PHP. I used the PHP EXECUTE command to call a PHP file. But since 4D v12 PHP does not have native support for cURL I used file_get_contents()
My 4D code is as follows:
C_TEXT($result)
C_TEXT($param1)
C_BOOLEAN($isOk)
$param1:="Tiger"
//someFunction is a function in index.php. $result will hold the JSON return value.
//I pass value "Tiger" as parameter
$isOk:=PHP Execute("C:\\index.php";"someFunction";$result;$param1)
C:\index.php contains the PHP script that 4D v12 will run. The code is
<?php
function someFunction($p1){
$somekey = 'A$ga593^bna,al';
$api_URL = 'https://somewhere.com/api/?key='. $somekey. '¶m='.$p1;
return file_get_contents($api_URL);
}
?>
This approach is applicable for GET request. But this already serves my purpose.
I'd like to know if it's possible to turn a Json file API like this one :
http://graph.facebook.com/10152830671619648/photos?fields=id,name,source
to a MySQL data table in a database.
What language shall I use for this ? PHP, Javascript ?
Thanks for answering !
EDIT : Actually, I'd like to create a system to manage the comics I need to buy with a simple interface. All the information about a comic book will be stored in a database (id, name, image link, if I need it, if I have it, if I read it).
In PHP, there are several ways to get the JSON object from url including fopen, get_file_contents and curl, the latter being the more reliable option if there are restrictions on the server.
JSON url to PHP object:
- Get JSON object from URL
Serialize and store to db:
- How do I store an php object in a MySQL table?
or write object properties to db table columns:
- mysqli: http://php.net/manual/en/mysqli-stmt.bind-param.php pdo:
- http://php.net/manual/en/pdostatement.bindparam.php
JavaScript can be used as well, using Ajax to both retrieve the JSON object and to store it in the db e.g. by sending it to a server-side script which do the storing. You can use PHP, PHP and JavaScript (Ajax), JavaScript and some JavaScript Ajax APIs, etc.
I'm trying to send Json text using $this_helper->json->sendJson('Ôtre'=>'Être'
but the problem is the special caracters not recongnized. how i can force zend to send appropriat Json.?
There is a problem with some PHP Versions when encoding Special chars. You can overship the problem by setting the following:
Zend_Json::$useBuiltinEncoderDecoder = true;
It seems that Yahoo pipes are represented using JSON. I want to download these JSON objects for some research purpose. Usually a Yahoo pipe is rendered in a browser editor thru a url like this: http://pipes.yahoo.com/pipes/pipe.edit?_id=XgRo96h13BGtJWvS8SvLAg, but you can't get the corresponding JSON object to this Yahoo pipe. Does anyone know how to get JSON objects representing Yahoo pipes and store them in any persistent form?
It is possible to get hold of a JSON description of a Yahoo Pipe using a URL of the form:
http://pipes.yahoo.com/pipes/pipe.info?_out=json&_id=PIPE_ID
The pipe2py python library demonstrates how to grab the JSON description of a pipe and "compile" it to a Python equivalent that can be run on your own server.
The post Exporting Yahoo Pipe Definitions, Compiling Them to Python, and Running Them in Scraperwiki describes how you can use pipe2py in the Scraperwiki environment to compile and execute pipes on Scraperwiki using pipe definitions imported directly from Yahoo Pipes, or exported from Yahoo Pipes and then stored locally in a Scraperwiki database table.
When I load that page in a browser I can see that it makes an ajax request for:
http://pipes.yahoo.com/pipes/ajax.pipe.load?id=XgRo96h13BGtJWvS8SvLAg&_out=json&modinfo=true&rnd=7560&.crumb=MjvGjpzhPLl
That's your object but I'm not sure if I'm answering your question of how to "get it". If you need to get it through a program you would need a script that loges into pipes and extracts that url.
A quick way, while not automated, is to use an HTTP analyzer. Here's a process for getting the object using HttpFox (I use v0.8.9) for Firefox. With the analyzer running, load the edit page for a pipe, like the one you linked:
http://pipes.yahoo.com/pipes/pipe.edit?_id=XgRo96h13BGtJWvS8SvLAg
Look at the request with a URL that starts with:
http://pipes.yahoo.com/pipes/ajax.pipe.load?id=....
Next, explore the content of the request (there's a 'Content' tab in HttpFox). That's the JSON object representing the pipe structure.
Use pipe.run?[your pipe id here]&_render=json as opposed to pipe.edit
So in your case to get the json it would be - http://pipes.yahoo.com/pipes/pipe.run?_id=XgRo96h13BGtJWvS8SvLAg&_render=json
I guess how you implement the client is dependent on what you like writing in/what other functionality you need.
You could also do it the other way around and use the web service service module to post the data to a script that can extract the json and persist it to a database. You could check out json.org.
IIs there a package similar to HTml::Template in perl which takes a JSON object and maps it to a HTML template file? I am building a web application using HTML::Template and will be receiving JSOn from a web services API, things will be made simple if I can templatize this JSOn to HTML instead of doing it the exact way HTML::Template requires.
HTML::Template just takes a data structure consisting of strings, hashes and arrays. JSON maps directly onto that.
$template->param(myData => JSON::Any->new->decode($json_string));
HTML::Template is a rather 'simple' templating engine - I am using quotes because its simplicity let's you do whatever you need in a view part from the Model View Controller architecture.
However, you can not execute arbitrary perl code inside a HTML::Template.
Also, due to the fact that in JSON you could have very complex data structures, I doubt that there are any suitable ways of using JSON in a straight way in your templates.
The only solution I see as possible is for you to use a Perl script that will parse the JSON, create some 'objects' and pass them to your templates. You already have that perl script - is the one that instantiate your HTML::Template object.
ok, a bit late, but:
HTML::Template always wants a hash of arrays of hashes and so on.
and you cannot navigate through the parameter stash.
If you want to do this, you might try out HTML::Template::Compiled which allows you to do this.
<tmpl_var some_hash.key.another_key[23] >
or with alternative delimiters:
[%= some_hash.key.another_key[23] %]
but note the documented differences of the module to HTML::Template.
So you decode your JSON string to a data structure and pass it to the template and then you can access all values somewhere deep in the structure.
