Dynamics 365利用HTML页面创建实体记录并同步上传附件

我是微软Dynamcis 365 & Power Platform方面的工程师罗勇，也是2015年7月到2018年6月连续三年Dynamics CRM/Business Solutions方面的微软最有价值专家(Microsoft MVP)，欢迎关注我的微信公众号 MSFTDynamics365erLuoYong ，回复342或者20190605可方便获取本文，同时可以在第一间得到我发布的最新博文信息，follow me!

关于Deep Insert请参考我的博文：Dynamics CRM 中Web API中的深度创建(Deep Insert) 我这里不再赘述。

JavaScript的 instanceOfFileReader.readAsDataURL(blob) 方法刚好能将要上传的文件内容读成base64编码，我们知道Dynamics 365 Customer Engagement中的附件存储在数据库中就是base64格式。

我下面直接上代码：

<!DOCTYPE html><html><head>    <meta http-equiv="X-UA-Compatible" content="IE=edge">    <meta http-equiv="Content-Type" content="text/html; charset=utf-8">    <title>罗勇开发的示例程序</title>    <script src="../../../ClientGlobalContext.js.aspx" type="text/javascript"></script>    <script type="text/javascript">        function createCaseandNote() {            var file = document.querySelector("#img").files[0];            var reader = new FileReader();            if (file) {                reader.readAsDataURL(file);            }            reader.addEventListener("load", function () {                console.log(file.name);                console.log(file.type);                console.log(file.size);                console.log(file.lastModifiedDate);                console.log(reader.result);                var result = reader.result;                var base64result = result.substring(result.indexOf(";base64,") + 8);                var requestJson = {                    "title": "罗勇示例Case",                    "customerid_account@odata.bind": "/accounts(f9fa6e76-ab12-e811-a959-000d3a109495)",                    "description": "罗勇通过代码一次创建case及其附件的示例",                    "Incident_Annotation":                        [                            {                                "subject": file.size.toString(),                                "notetext": file.lastModifiedDate,                                "mimetype": file.type,                                "isdocument": true,                                "filename": file.name,                                "documentbody": base64result                            }                        ]                };                var clientURL = Xrm.Utility.getGlobalContext().getClientUrl();                var req = new XMLHttpRequest()                req.open("POST", encodeURI(clientURL + "/api/data/v9.1/incidents", false));                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) {//204代表成功无返回值                            var currentAppUrl = Xrm.Utility.getGlobalContext().getCurrentAppUrl();                            if (currentAppUrl.indexOf("appid=") <= -1) {                                currentAppUrl += "/main.aspx?";                            }                            else {                                currentAppUrl += "&";                            }                            Xrm.Navigation.openUrl(currentAppUrl + "pagetype=entityrecord&etn=incident&id=" + this.getResponseHeader("OData-EntityId").match(/\w{8}-\w{4}-\w{4}-\w{4}-\w{12}/)[0] + "&navbar=off&cmdbar=false");                        }                        else {                            var error = JSON.parse(this.response).error;                            alert("错误：" + error.message);                        }                    }                };                req.send(JSON.stringify(requestJson));                            }, false);        }        function previewFile() {            var preview = document.querySelector('#imgprivew');            var file = document.querySelector("#img").files[0];            var reader = new FileReader();            reader.addEventListener("load", function () {                preview.src = reader.result;            }, false);            if (file) {                reader.readAsDataURL(file);            }        }    </script></head><body>    <input id="img" type="file" onchange="previewFile()">    <input type="button" onclick="createCaseandNote()" value="上传并创建案例及包含附件的注释" /><br />    <img id="imgprivew" src="" width="600" alt="Image preview..."></body></html>

效果如图，选择图片后有预览效果，点击按钮后会使用Deep Insert同步创建一个Case实体记录并同时将该附件作为注释和该case实体记录关联。

创建后打开的case实体记录效果如下：
