What I am trying to do is to send a JSON array (that was gotten from Guzzle) to my SQL database. I have gotten to the point where I am able to get the response and display the gotten JSON array on a webpage. The array is defined as the $data
variable. The $data
variable gets decoded using this:
$data = json_decode($response->getBody()->getContents());
This is able to get the JSON and decode it with no problem. The part I am stuck on is taking the $data
variable, processing it and sending it to my database. From what I understand is that you are required to convert the JSON into an array and then send it to the database.
The JSON format is like this:
[{
"INTLDES": "2017-042Z",
"NORAD_CAT_ID": "42848",
"OBJECT_TYPE": "TBA",
"SATNAME": "OBJECT Z",
"COUNTRY": "TBD",
"LAUNCH": "2017-07-14",
"SITE": "TTMTR",
"DECAY": null,
"PERIOD": "96.52",
"INCLINATION": "97.61",
"APOGEE": "597",
"PERIGEE": "586",
"COMMENT": null,
"COMMENTCODE": null,
"RCSVALUE": "0",
"RCS_SIZE": null,
"FILE": "6242",
"LAUNCH_YEAR": "2017",
"LAUNCH_NUM": "42",
"LAUNCH_PIECE": "Z",
"CURRENT": "Y",
"OBJECT_NAME": "OBJECT Z",
"OBJECT_ID": "2017-042Z",
"OBJECT_NUMBER": "42848"
}]
My Satellite Model goes like this:
protected $fillable = [
'intldes',
'norad_cat_id',
'object_type',
'satname',
'country',
'launch',
'site',
'decay',
'period',
'inclination',
'apogee',
'perigee',
'comment',
'commentcode',
'rcsvalue',
'rcs_size',
'file',
'launch_year',
'launch_num',
'launch_piece',
'current',
'object_name',
'object_id',
'object_number'
];
My migrations file:
Schema::create('satellites', function (Blueprint $table) {
$table->increments('id');
$table->string('intldes');
$table->string('norad_cat_id');
$table->string('object_type');
$table->string('satname');
$table->string('country');
$table->string('launch')->nullable();
$table->string('site')->nullable();
$table->string('decay')->nullable();
$table->string('period')->nullable();
$table->string('inclination')->nullable();
$table->string('apogee')->nullable();
$table->string('perigee')->nullable();
$table->string('comment')->nullable();
$table->string('commentcode')->nullable();
$table->string('rcsvalue')->nullable();
$table->string('rcs_size')->nullable();
$table->string('file')->nullable();
$table->string('launch_year')->nullable();
$table->string('launch_num')->nullable();
$table->string('launch_piece')->nullable();
$table->string('current')->nullable();
$table->string('object_name');
$table->string('object_id');
$table->string('object_number');
$table->timestamps();
});
I tried making an $object
array, which did not work.
TL;DR: I want to take the $data
variable, which contains the decoded JSON and create something that allows it to get saved into my 'satellites' SQL database.
EDIT: Here is the full Satellite controller:
public function displayer(){
$api = new Client([
'base_uri' => 'https://www.space-track.org',
'cookies' => true,
]); $api->post('ajaxauth/login', [
'form_params' => [
'identity' => '#',
'password' => '#',
],
]);
$response = $api->get('basicspacedata/query/class/satcat/orderby/INTLDES%20desc/limit/5/metadata/false');
$data = json_decode($response->getBody()->getContents(), true);
$data = array_change_key_case($data, CASE_LOWER);
$model = Satellite::create($data);
dd($data);
}
It looks like your JSON key names match up nicely with your model attributes, with the exception of being capitalised.
Try mapping the data keys to lowercase and then creating your model instance. Per @OmisakinOluwatobi suggestion, you can use pass true
to json_decode
to retrieve the data as an array.
Edit - I missed that your response data was an array of objects. The following update will iterate over the response data and create a new Satellite
for each.
// Retrieve data from response
$data = json_decode($response->getBody()->getContents(), true);
// Iterate over response data
foreach ($data as $attributes) {
// Change attribute keys to lowercase
$attributes = array_change_key_case($attributes, CASE_LOWER);
// Create satellite model
Satellite::create($attributes);
}
It is actually as simple as $encoded = json_encode($request->your_array);
. This $encoded
will now be "savable" to sql database. When you later access the encoded data, you can use a JSON parser to convert back to a json array. Example using jQuery var your_array = $.parseJSON($response.body);
