[Plugin] Http/s REST, blueprintable JSON and Parse REST API manager at once (VaRest)

[robotnicbw]

I am having difficulty with multiple POSTs to the same server. At Event BeginPlay the POST request is set up with the JSON buffer and POST request structure and attached to callbacks for request complete or failure. During runtime, calls are made to issue this post with a single field ("action") in the buffer. The first post goes through just fine (get response code 200 from server), but the second one seems to get through the VArest code (see "LogVaRest: Request (url body): POST ..." in output log), but the server doesn't see the message. Even running wireshark on the UE machine shows the POST not going out. Exactly three minutes after the second POST call I get a libcurl error on the output log, i.e., "LogHttp: Warning: 00000260BF1A9300: request failed, libcurl error: 0 (No error)". Am I modifying the JSON buffer correctly? Can the JSON buffer be reused like I do here? Hope this is the right place to post this kind of question.

Just posting to thank the OP for VaRest. Spent the day setting it up and coding a php/mysql login system. Worked perfectly. Thank you.

Yes, it's a deprecated field now. For valid responses use ResponseObj->Decode

I have been trying to GET / POST data using only blueprints, but it is not working... I tryied "GET RESPONSE OBJECT" then "DECODE JSON", but the decode only returns a boolean. Shouldn't it return a string? How do I access the data from the website?

I went through the documentation, but it is outdated since the "GET RESPONSE CONTENT" is deprecated.

Thank you

when I wanted to use "GetResponseContent" It gives me This notification:

DEPRECATED: please use GetResponseContentAsString() instead

and when I use that it just shows this:
{}

so please help me I reeeaaaaallyyy need to use your plugin in Unreal Engine 4

Just show me to the direction to learn

I really can use some help here:

on the web side I encode my Data and it returns some thing like this:
{"status": "online","username": "shakoor","email": "shakoor@sh.com","banned": "no","kills": "0","wins": "0"}
so i will use "Get Field" and it works fine but when I have some thing like this on the server:
{"status": "online","username": "shakoor","email": "shakoor@sh.com","banned": "no","kills": "0","wins": "0"}{"status": "online","username": "shakoor2","email": "shakoor@sh.com2","banned": "no","kills": "0","wins": "0"}

So I have more than 1 json object and let's say I want to show the second result
I just don't know how proceed
you see the same code works fine for 1 json object but when it is more than 1 it doesn't work
so please please
help me
all I want to do is to have list of specific data on the server encoded as json and show them all
that is it
"GetResponseContent" will print everything I guess, but it does not work anymore (Deprecated)

thank you again for your attention

Request fails in packaged build for android

Hi,
I packaged the android apk and installed on Moto G5 S Plus. When i request the url on button. It always fails.

I also disabled the Verify Peer. But it didn't work.




Plugin Version:
"Version" : 22,
"VersionName" : "1.1-r22",

Engine Version: 4.19.1 Release

Log File : https://github.com/ufna/VaRest/files/2144949/mylog.log

This is working perfectly so far, except, I don't get any difference between the 'Encode JSON' node and the 'Encode JSON to Single String' node. Both are creating single-line JSON nodes, and as I am exporting these to external .json files this is a bit messy.

Anyone else experiencing this on 4.20?

I am having some trouble doing this in C++
any help to do the BindEvent To OnRequestComplete Function To another Function call "TempFunction"


this is what I have so far::

FLatentActionInfo latentInfo;
Request = UVaRestRequestJSON::ConstructRequestExt(this, ERequestVerb::GET, ERequestContentType::x_www_form_urlencoded_url);
Request->ApplyURL(UrlGetIp, RequestObject, this, latentInfo);
Request->OnRequestComplete;

been trying for over 4 hours to figure out.

Hey @ufna
I just wanted to ask if it is possible to use the Bing Speech API with your Plugin.
It works like this: First you send a Authentication Key and audio file to the server and then you get a response in form of a JSON.
Does this work with your plugin?

I'm currently trying to use VaRest to login to a server via a third party api.

I should be able to login by either processing a cURL or by passing headers and a body via a url.
I've not be able to get VaRest to post correctly to the server.

If I copy the cURL link from the api dashboard and into the Process URL node then the request fails and i get the same if i follow the logic in the attached screenshot. When i'm using the Set String Request Content, i'm only doing so because I couldn't find anything else relating to adding body content.

I have experience working with PHP before inside of Unity but this is my first time using posting JSON so i'm sure there is something really simple that i'm missing.

EDIT:
So it seems to be working now using the Set String Field and Set Fields. How ever nesting a JSON field inside a field adds in square brackets and not curly brackets along with another formatting issue. Can anyone suggest how to get around this. I'll attach a screen shot.

Will this get updated to 4.21?

Having a little bit of a problem parsing the data within the blueprints my API is returning this as a JSON object but i can't seem to figure out how to break the object up to use the data.

API Response:

 
 {"playerinfo":{"Friends":"none","Lifetime_Score":0,"Facebook_ID":"0","User_ID":141,"Stars":"0","UserName":" ","Google_ID":"0"},"scores":{"Level":1,"Chapter":1,"Score":200,"Player_ID":141}}

Blueprint is attached. Thanks in advance this plugin has saved me a lot of time!

SOLVED: I fixed my own problem I am editing post to reflect solution.

My application of this plugin is retrieving information from Elasticsearch using its rest api. I have been able to send a simple get request and confirm that I can reach my server, but I cannot figure out how to use the blueprint nodes to construct my request. I am used to using the curl command when sending json to the api and so that is how I will show you what I am trying to accomplish. I am trying to do the equivalent of the following. curl -X GET "localhost:9200/twitter/_search" -H 'Content-Type: application/json' -d'
{
"query" : {
"term" : { "user" : "kimchy" }
}
}
'

I tried to understand how to send this using this blueprint plugin but have become very frustrated and thus I am asking for help. I think I need to somehow set the request body but I am not sure how to do this. If anyone is willing to help that would be greatly appreciated.

What I was doing wrong was not setting the request object after making the request. I also learned that the request object needed to be a json object using the field body and then my above json as the value(using the construct json object combined with set string field), I am attaching a quick screenshot of this for anyyone in the future.
