Re: REST in Pawn - Communicate with JSON REST APIs

Hello!

I'm having a problem with my Post command. My server gets the post JSON data, but the plugin won't execute the function after. I'm calling DoSomething() function in OnPluginStart(). My code:

PHP Code:


		
			
public void DoSomething(){

    PrintToServer("We are in DoSomething");

    httpClient = new HTTPClient("http://ip.to.my.server");



    JSONObject port = new JSONObject();

    port.SetInt("port", iPort);



    httpClient.Post("api/get_postfromcsgoserver", port, OnPortResponse);



    PrintToServer("We are in DoSomething2");

    delete port;



}



public void OnPortResponse(HTTPResponse response, any value){

    PrintToServer("We are in OnPortResponse");

    if(response.Status != HTTPStatus_Created) {

        PrintToServer("!= HTTPStatus_Created");

        return;

    }

    if (response.Data == null){

        PrintToServer("response.data == null");

        return;

    }

}

The latter is just a part of the function. I don't get any compilation errors. It won't even print the "We are in OnPortResponse" to the server.

Does connection have to be https?

I get this from my server that the plugin tries to Post so it's working
[07/Nov/2017 14:28:09] "POST /api/get_postfromcsgoserver/ HTTP/1.1" 200 98

Thank you!

You need to turn off the invernation of the server, or enter to the server.

Re: REST in Pawn - Communicate with JSON REST APIs

So, i forked this extension 31 oct. 2017, and made small changes.

Fixed segfault
Added timeout connection and waiting response, "Follow location" settings in HTTPClient methodmap.
IChangeableForward removed, now extension uses IPluginFunction.
Callback modified: added ability for receive error string.

Code:

public void OnRequestFinished(HTTPResponse hResponse, any iData, const char[] szError) { if (szError[0] != 0) { LogError("Error received when processing request: %s", szError); return; } // handle response... }

But you can still use this old function prototype, without receiving error message:

Code:

public void OnRequestFinished(HTTPResponse hResponse, any iData) { // handle response... }

But in this case, you should add check:

Code:

if (hResponse != null)

You can see source code here. Download binaries here.

Re: REST in Pawn - Communicate with JSON REST APIs

Sorry if this has been asked before, but...
Is there a way to allow the use of self signed SSL certificates? I am getting a BADCERT_CN_MISMATCH error when using a self signed HTTPS URI rest api.

Code:

L 07/08/2018 - 19:32:20: [RIPEXT] HTTP request failed: Cert verify failed: BADCERT_CN_MISMATCH

Re: REST in Pawn - Communicate with JSON REST APIs

I managed to get the self signed certificate to work - Thanks for helping me out at GitHub.

However, I have another problem... this does not work:

Code:

#include <sourcemod>

#include <ripext>



public void OnPluginStart()

{

        PrintToServer("Testing JSONObject...");

        JSONObject obj = new JSONObject();

        obj.SetString("test", "ð");

        decl String:test[10];

        obj.GetString("test", test, sizeof(test));

        delete obj;

        PrintToServer("test: %s", test);

        PrintToServer("Finished testing JSONObject");

}

What the server responds is this:

Code:

sm plugins load test

Testing JSONObject...

L 07/13/2018 - 11:35:58: [SM] Native "JSONObject.GetString" reported: Could not retrieve value for key 'test'

L 07/13/2018 - 11:35:58: [SM] Displaying call stack trace for plugin "test.smx":

L 07/13/2018 - 11:35:58: [SM]   [0]  Line 10, test.sp::OnPluginStart()

[SM] Loaded plugin test.smx successfully.

I am trying to send player name to a REST API. It seems some player names fail to work with the JSONObject. Not always though, and that is what I don't quite understand. I am thinking base64 encoding the names, but I was hoping there was a better solution for this.

Here's another example:

Code:

#include <sourcemod>

#include <ripext>



public void OnPluginStart()

{

        PrintToServer("Testing JSONObject...");

        JSONObject obj = new JSONObject();

        obj.SetString("test1", "We start here...");

        obj.SetString("test2", "ð");

        obj.SetString("test3", ".. and here we are");

        decl String:json[64];

        obj.ToString(json, sizeof(json));

        delete obj;

        PrintToServer("json: %s", json);

        PrintToServer("Finished testing JSONObject");

}

What the server responds is this:

Code:

sm plugins load test

Testing JSONObject...

json: {"test1": "We start here...", "test3": ".. and here we are"}

Finished testing JSONObject

[SM] Loaded plugin test.smx successfully.

Re: REST in Pawn - Communicate with JSON REST APIs

Hello!

I'm trying to load JSON from a file, but I'm getting an error. Anyone any help?

PHP Code:


		
			

    char path[PLATFORM_MAX_PATH + 1];
    BuildPath(Path_SM, path, sizeof(path), "data/match.json");
    PrintToServer("FileExists %d", FileExists(path));

    JSONObject data = JSONObject.FromFile(path);

Error:

PHP Code:


		
			
"[RIPEXT] Invalid JSON in line -1, column -1: unable to 
open addons/sourcemod/data/match.json: No such file or directory"

PrintToServer("FileExists %d", FileExists(path)); <- This prints "FileExists: 1"

File:

PHP Code:


		
			
{
    "map": "de_dust2",
    "uuid": "awawras4aw4as4sa"
}

EDIT: Apparently when I add the absolute path of the JSON file to "JSONObject data = JSONObject.FromFile(path);" it works but not with the Path_SM

Re: REST in Pawn 1.1 - HTTP client for JSON REST APIs (Updated 2019/12/28)

So you base64-encoded "username:password" and appended the result after "Basic ", as explained on the page I linked?

Edit: seems to work.

PHP Code:


		
			
public void OnPluginStart()

{

    HTTPClient client = new HTTPClient("https://jigsaw.w3.org/HTTP");

    client.SetHeader("Authorization", "Basic Z3Vlc3Q6Z3Vlc3Q=");

    client.Get("Basic", OnHTTPResponse);

}



public void OnHTTPResponse(HTTPResponse response, any value)

{

    PrintToServer("[Basic] %d", response.Status);

}

This returns a 200 response. If you comment out client.SetHeader() it returns a 401 response.

Re: REST in Pawn 1.1 - HTTP client for JSON REST APIs (Updated 2020/03/24)

Hi DJ Tsunami

Firstly many thanks for making this extension. It is fantastic!

Back in 2017 you mentioned that JSONObject iteration was not possible. I am wondering if this is still the case?

Here is an example of what I'm trying to do:

PHP Code:


		
			
{
    "cvars":{
        "mp_startmoney": "800",
        "mp_maxmoney": "16000",
    }
}

I would like to iterate over the "cvars" property, extracting both the key and value for further processing.

How would I go about this? Is it possible to retrieve an array of keys from a JSONObject? Alternatively is it possible to extract the keys in a similar fashion to StringMaps, via StringMapSnapshot.GetKey(index)?

Thanks a lot

DJ Tsunami

05-19-2020 03:52

Re: REST in Pawn 1.1 - HTTP client for JSON REST APIs (Updated 2020/03/24)

It's still not possible, but your use case is legitimate, so I'll look into it.

You'll have to check the request body in PHP instead of the request parameters. Check this.

The request Content-Type is application/json instead of application/x-www-form-urlencoded.

PHP Code:


		
			
$body = file_get_contents('php://input');

$data = json_decode($body);

No, if your HTTP client is defined globally, there's no reason to delete it. You can just reuse it for future requests.

Re: REST in Pawn 1.2 - HTTP client for JSON REST APIs (Updated 2020/07/16)

Is there anyway to get the file that was uploaded in "OnImageUploaded". You can pass a value, but you cant pass a string (unless i'm missing something here).
