不借助工具在浏览器中通过Web API执行Dynamics 365操作(Action)实例

我的上一篇文章 利用Fiddler修改请求信息通过Web API执行Dynamics 365操作(Action)实例 借助了Fiddler工具，你可能会问，如果不借助工具，我只有浏览器可行吗？这就是本文要讲述的。

我们知道一般浏览器按F12会出来开发者工具，我们以Chrome为例来讲解，还是和前面博文一样，执行一样的操作。

请选择开发者工具的 Console 这个页签，为了方便输入代码，请清空这个页签中的东西，然后我输入下面的JavaScript代码：

var clientURL = Xrm.Page.context.getClientUrl();
var req = new XMLHttpRequest()
req.open("POST", encodeURI(clientURL + "/api/data/v8.2/workflows(6BEBC426-F722-4B64-AE5D-0DA379F8A8C4)/Microsoft.Dynamics.CRM.ExecuteWorkflow"), true);
req.setRequestHeader("Accept", "application/json");
req.setRequestHeader("Content-Type", "application/json; charset=utf-8");
req.setRequestHeader("OData-MaxVersion", "4.0");
req.setRequestHeader("OData-Version", "4.0");
req.onreadystatechange = function () {
  if (this.readyState == 4 /* complete */) {
    req.onreadystatechange = null;
    if (this.status == 200) {
      Xrm.Utility.alertDialog("执行成功!");
          console.log(this.responseText);
    }
        else {
          Xrm.Utility.alertDialog("执行出错。");
          console.log(this.responseText);
    }
     }
  };
var requestMsg = {};
requestMsg.EntityId = "B907DE1B-CF99-E611-8161-000D3A80C8B8";
req.send(JSON.stringify(requestMsg));

输完后按回车键，很快代码执行完毕提示我成功了：

我点击确定后代码将获取到的返回内容写入了控制台(console)，如下：

 这个是不是更加需要点技术活，需要你会写JavaScript代码，其中带来的好处我就不说啦，相信聪明的朋友可以猜到。

下面补充几个实际的例子。

1. 更新contact记录的owner为指定的团队。

var clientURL = Xrm.Page.context.getClientUrl();
var req = new XMLHttpRequest()
req.open("PATCH", encodeURI(clientURL + "/api/data/v8.2/contacts(2dbe9781-3c00-e911-80f4-fb0c1b62c870)"), true);
req.setRequestHeader("Accept", "application/json");
req.setRequestHeader("Content-Type", "application/json; charset=utf-8");
req.setRequestHeader("OData-MaxVersion", "4.0");
req.setRequestHeader("OData-Version", "4.0");
req.onreadystatechange = function () {
    if (this.readyState == 4 /* complete */) {
        req.onreadystatechange = null;
        if (this.status == 204) {
            Xrm.Utility.alertDialog("记录修改成功!");
        }
        else {
            var error = JSON.parse(this.response).error;
            Xrm.Utility.alertDialog("修改记录出错." + error.message);
        }
    }
};
var requestMsg = {};
requestMsg["ownerid@odata.bind"] = "/teams(C36E8B6E-44FB-E711-80F4-3863BB35BF30)"
req.send(JSON.stringify(requestMsg));

2. 通过 AddToQueue 消息将SR添加到指定队列：

var actionUrl = "/api/data/v8.2/queues(CA4CB0B1-1CC8-E611-80DA-005056AA01A1)/Microsoft.Dynamics.CRM.AddToQueue";
var addToQueueContent = {
    "Target": {
        "incidentid": "B7367B58-8C55-E811-80F6-005056AA43CC",
        "@odata.type": "Microsoft.Dynamics.CRM.incident"
    }
};
                                     
var req = new XMLHttpRequest();
req.open("POST", encodeURI(Xrm.Page.context.getClientUrl() + actionUrl), true);
req.setRequestHeader("Accept", "application/json");
req.setRequestHeader("Content-Type", "application/json; charset=utf-8");
req.setRequestHeader("OData-MaxVersion", "4.0");
req.setRequestHeader("OData-Version", "4.0");
req.onreadystatechange = function () {
    if (this.readyState == 4 /* complete */) {
        req.onreadystatechange = null;
        if (this.status == 200 || this.status == 204) {
            Xrm.Utility.alertDialog("操作成功!");
        }
        else {
            alert("操作失败：" + JSON.parse(this.response).error.message)
        }
    }
};
req.send(JSON.stringify(addToQueueContent));

3. 通过 CloseIncident 消息来关闭SR，注意自己指定关闭SR时候的subject和statuscode

var clientURL = Xrm.Page.context.getClientUrl();
var req = new XMLHttpRequest()
req.open("POST", encodeURI(clientURL + "/api/data/v8.2/CloseIncident"), true);
req.setRequestHeader("Accept", "application/json");
req.setRequestHeader("Content-Type", "application/json; charset=utf-8");
req.setRequestHeader("OData-MaxVersion", "4.0");
req.setRequestHeader("OData-Version", "4.0");
req.onreadystatechange = function () {
    if (this.readyState == 4 /* complete */) {
        req.onreadystatechange = null;
        if (this.status == 204) {
            Xrm.Utility.alertDialog("将SR关闭成功!");
        }
        else {
            var error = JSON.parse(this.response).error;
            Xrm.Utility.alertDialog("将SR关闭出错." + error.message);
        }
    }
};
var requestmsg = {};
requestmsg.IncidentResolution = {};
requestmsg.IncidentResolution.subject = "Cancel Sr";
requestmsg.IncidentResolution["incidentid@odata.bind"] = "/incidents(46704E83-F85E-E811-8135-E0071B672C21)";
requestmsg.Status = 100000026;
req.send(JSON.stringify(requestmsg));
