I check against my web server, and the GET its correct, i copy from logs the URL and paste in firefox changing the domain to google and on firefox work, i got the expect response in JSON format. What i missed?

ufna · December 3, 2015, 8:05pm

Please provide the url to test, I’ll check it. Possible you should update the plugin from the develop branch, I’ve fixed some issues with GET requests in it.

knack · December 3, 2015, 8:08pm

i give you on private because its using my public api and have limit to 100 querys/day

ufna · December 3, 2015, 8:11pm

Sure, pls PM me

knack · December 4, 2015, 11:05am

yesterday i have a bad day with other php errors too, 3 hours without doing a simple task for get the mysql data and creating a array with the right format. Sometimes its better go to sleep and try next day hehe, i wake up and in five minutes …

i post here that simple code, perhaps can be useful for someone without too much php knowledge.

<?php
/*

*/
error_reporting(E_ALL);

require(‘…/config/config.inc.php’); //common config vars
require(‘…/db/db.mysql.php’); // db_query -> mysqli_db_query… and the others
require(‘…/include/common.inc.php’); // connect to db && session && other common things

$json = file_get_contents(‘php://input’);
$json_phpvar = json_decode($json);

if (isset($json_phpvar) && ($json_phpvar->{‘request’} == “categories”)) {
$result_array = array();
$query = db_query("SELECT * FROM categories");
while ($row = db_fetch($query)) {
    	$result_array'categories']] = $row;
}
echo json_encode($result_array, JSON_UNESCAPED_SLASHES);
exit(0);
}

?>

I sent from UE4 a “request”:“categories” in POST/JSON format. categories its a simple table with catid and catname values

Hotfix release: Release VaRest v1.1-r12 · ufna/VaRest · GitHub

TheParadox · December 24, 2015, 12:12am

Hey, get plugin loving it. This is my first time posting on the forums SO NOT SURE HOW this is will work or if there will be two posts…

So everything is working how it should be HOWEVER (love that word, says there is trouble…) I am getting an error:
“LogVaRest:Error: Json Value of type ‘None’ used as a ‘Number’.”

-There is one for every object returned, I have attempted to disconnect all pins etc, and I still get it.
The data is: (along with type, yes its valid) the italicized parts are what was changed - they where floats/doubles before
{
“data”: {
“id”: 1, <-int
“name”: “G0FK”, <-varchar
“type”: “G”, <-char

```
  "xPC": -33, &lt;-int
  "xAU": 48404, &lt;-int
  "yPC": 15, &lt;-int
  "yAU": 68783, &lt;-int*
  "zPC": 0 &lt;-int
```
}, {
“id”: 2,
“name”: “G1FS”,
“type”: “G”,
“xPC”: -51,
“xAU”: -80386,
“yPC”: -43,
“yAU”: 67324,
“zPC”: 0
}
]
}

and an image -

ufna · December 26, 2015, 1:20pm

Use GetStringField, GetNumberField, etc. instead of GetField (which returns Object type).

TheParadox · December 26, 2015, 2:54pm

Ah, okay that makes sense.
Works, thanks!

Hey guys, been trying to figure out how to install/compile this plugin for Mac, can anyone point me in the right direction?

polygon · December 31, 2015, 4:00pm

Hi,

This Plugin looks really awesome but could someome please show a “usage example for dummies”?

In other words: What exactly is required to store Player data online in a secure and reliable way?
I’ve created a MySQL Database and downloaded Varest. What’s the next step to get ist working? Do you need some php bridge or another kind of form? How would this be done?
I’d really need a simple step by step Guide that shows how to exchange Data between ue and the database and vice versa.

Thanks and best regards,
Daniel

Control · January 6, 2016, 3:31pm

Hello please could you update it to newer version. I t looks amazing.

Control · January 8, 2016, 11:22pm

Hello, So how can I create a .json file with som arrays in it using this? And then send it to url or something. Please

Vindomire · January 22, 2016, 2:46am

Having issues figuring out the process on the UE4 end AFTER url has been processed. I get a json response:

LogVaRest: Response (200): {“newsdate”:“01-20-2016”,“title”:“Test News!”,“desc”:"This is a Test of the ability to read and display news to the client!

This is a new Line!"}

So i want to do things in UE4 with this information, i tried a ton of wrong ways apparently… i use this BP and i imagine im missing steps or something to be able to pull the information out of the fields…

http://puu.sh/mEPRA/e110dded35.png

LogJson:Warning: Field Title was not found.
LogJson:Error: Json Value of type ‘Null’ used as a ‘String’.

~~Anyone able to help me with this?~~

Got it working finally had to use the latent version, i think it was trying to get the values before they were ready with the other version.
