Tsung - How to send array or object in request parameters? - php

Question

I need to send object like php
$obj = [
array('id' => '111');
];
as POST request parameter.
I tried to use
[{struct,[{<<"id">>,<<"111">>},{<<"id">>, <<"222">>}]}]
[{struct,[{"id","111"}]}]
[{struct,[{"id":"111"}]}]
[{struct,[{"id"=>"111"}]}]
[[{"id","111"}]]
[{"id":"111"}]
[{"id"=>"111"}]
but it is wrong.
I tried to replace " by " but it's wrong too.
I don't find any examples in user manual about work with array or object. Does anyone faced with this question?

Answer 1

Build a query string using square brackets then URL encode it.
Example query string:
someArray[someindex_1][name]=blah&someArray[someindex_1][id]=123&someArray[someindex_2][name]=bah blah&someArray[someindex_2][id]=456
send the encoded string as the body of the post request. This should result in an array on the server like this:
print_r($_POST['someArray']);
// array(
// "someindex_1" => array(
// "name" => "blah"
// "id" => 123
// )
// "someindex_2" => array(
// "name" => "blah blah"
// "id" => 456
// )
//);

You can send an array in a POST request using the HTML element name with the square brackets "[]". An example is show below:
<input type="text" name="countries[]" value="Nigeria">
<input type="text" name="countries[]" value="Ghana">
Then in your PHP code, you can retrieve the values this way:
$countries = $_POST['countries']; //$countries is now an array of POST-ed countries
var_dump($countries);
But if what you want to send across is an Object, then you have to serialize it. You can use the code below:
$obj = get_an_object_somehow();
$encoded_obj = base64_encode(serialize($obj));
Then in your HTML form:
<input type="text" name="myObj" value="$encoded_obj">
Finally, in your form processing script, you can unserialize it as follows:
$decoded_obj = unserialize(base64_decode($obj));//get back original object
var_dump($decoded_obj);
