我需要从 Javascript 调用操作流程。我的操作接受 2 个输入参数和 1 个输出参数。下面是我的Action的截图

我的表单中有一个文本字段，在其onChange事件中我调用此 CallAction 方法。下面是 JavaScript

function CallAction() {

        var actionName = "taqi_getPrice";
        var actionParameters = {
            "base": "USD",
            "TotalPrice": "200"
        };
        var actionResponse = activateCustomAction(actionName, actionParameters);
    }
    function activateCustomAction(actionName, actionParams) {

        var req = new XMLHttpRequest();
        req.open("POST", Xrm.Page.context.getClientUrl() + "/api/data/v9.0/taqi_getPrice", false);
        req.setRequestHeader("OData-MaxVersion", "4.0");

        req.setRequestHeader("OData-Version", "4.0");
        req.setRequestHeader("Accept", "application/json");
        req.setRequestHeader("Content-Type", "application/json; charset=utf-8");
        req.onreadystatechange = function () {
            if (this.readyState === 4) {
                req.onreadystatechange = null;
                if (this.status === 200) {
                    var results = JSON.parse(this.response); …
