Json RPC请求通过jquery getJSON

Question

I am trying to send json-rpc request to remote server with jquery getJSON method. Here is my code:

json_string=JSON.stringify(obj);
var jqxhr = $.getJSON("https://91.199.226.106/ssljson.php?jsoncallback=?", json_string, function(data){
    alert("aaaaaa");
});
jqxhr.error(function() { alert("error"); })

Here is my json-rpc string example:

{"jsonrpc":"2.0","method":"merchant_check","params":[{"hostID":150999,"orderID":116,"amount":"150","currency":"051","mid":15001038,"tid":15531038,"mtpass":"12345","trxnDetails":""}],"id":116}

And here is the error I get:

{"jsonrpc":"2.0","id":null,"error":{"code":-32600,"message":"Invalid JSON-RPC 2.0 request error (-32600)"}}

I can`t get what is the issue. Am I doing something wrong? Maybe I need to send request with php and not jquery? Then how should I do it?

The getJSON as the name say will send GET request if you want to use JSON-RPC you need to use POST like:

var json_string = JSON.stringify(obj);
$.post('https://91.199.226.106/ssljson.php', json_string, function(response) {
   // process response
}, 'json');

but this will only work if your page is on the same server, unless you use CORS.
