API Help: JSON-rpc version not specified

[Parasin]

Hey all,

working on creating a script that can automatically synchronize my Zabbix servers by exporting the template data on one server, then importing that data to another Zabbix server.

I'm getting an error that i can't figure out when I try to run some Javascript, no matter what method I try:

JSON-rpc version is not specified.

Here is my Javascript:

function auth() {
    var auth;
    var url = 'http://<ip>/zabbix/api_jsonrpc.php';
    
    var req = {
        "jsonrpc":"2.0",
        "method":"user.login",
        "params": {
            "user":"<username>",
            "passowrd":"<password>"
        },
        "auth":null,
        "id":1
    };
    console.log(req);
    $.ajax({
		type: 'POST',
		data: req,
		contentType: 'application/json-rpc',
		url: url,
		success: function(data) {
            console.log(data);
            if(!data.error) {
                $(" #results ").text(data);
            }
            else {
                $(" #results ").text(data.error.data);
            }
	   },
        error: function(data) {
            $(" #results ").text(data.error.data);
        }
    });
}

auth();

The weird part is, when I run this curl command:

curl -i -X POST -H 'Content-Type: application/json' -d '{"jsonrpc":"2.0","method":"user.login","params":{"user":"<username>","password":"<password>"},"id":1,"auth":null}' http://<ip>/zabbix/api_jsonrpc.php

I get the correct results back:

{"jsonrpc":"2.0","result":"afcfbf67da00669c91b355e b84834372","id":1}

Any idea as to how I can adjust my Javascript to fix this error??

Solved!

Ok, so if anyone else encounters this issue, here is what I did to resolve it.

It appears that the Zabbix API actually parses a JSON string it does not directly take JSON-formatted data. So, if you are using Javascript to handle the connection to the Zabbix API, you have to send it as a string, formatted as JSON.

Example:

var req = {
        "jsonrpc":"2.0",
        "method":"apiinfo.version",
        "params": {
            "user":"<username>",
            "passowrd":"<password>"
        },
        "auth":null,
        "id":1
    };
    
    // Here is the AJAX call to the Zabbix API
    $.ajax({
		type: 'POST',
		[B]data: JSON.stringify(req)[/B],  //THIS LINE IS WHERE THE MAGIC HAPPENS
		contentType: 'application/json',
		url: url,
	        success: function(data) {
                    console.log(data);
                    if(!data.error) {
                         $(" #results ").text(JSON.stringify(data));
                    }
                    else {
                        $(" #results ").text(data.error.data);
                    }
	        },
                error: function(data) {
                        $(" #results ").text(data.error.data);
               }
    });

That code returns the following results:

{"jsonrpc":"2.0","result":"2.4.4","id":1}

So in summary, you need to use the

JSON.stringify()

method on your data before attempting to pass it to the Zabbix API.
