如何从Javascript Microsoft Dynamics调用操作

Question

我需要从JavaScript调用操作过程。我的操作接受2个输入参数和1个输出参数。下面是我的行动截图

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);
                    alert('Success');
                } else {
                    alert('fail');
                    //Xrm.Utility.alertDialog(this.statusText);
                    console.log(this);
                }
            }
        };
        req.send(JSON.stringify(actionParams));
    }

有时还说

请求头字段access-control-allog-headers不允许access-control-allog-headers

好吧，我创建了与你在你的截图中提到的完全相同的动作，除了我使用的实体是帐户。我使用下面的代码来激发操作，它确实对我有效，没有任何问题，并按预期返回了值。

可能是为了测试，您可以提供静态Guid，看看您是如何得到结果的。

var parameters = {};
parameters.base = "123";
parameters.TotalPrice = "222";
var req = new XMLHttpRequest();
req.open("POST", Xrm.Page.context.getClientUrl() + "/api/data/v9.1/accounts(DC86C293-CA4F-E911-A82F-000D3A385A1C)/Microsoft.Dynamics.CRM.crmp_TestAction2", 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);
        } else {
            Xrm.Utility.alertDialog(this.statusText);
        }
    }
};
req.send(JSON.stringify(parameters));
