Dynamics 365 for Sales: Web API Client编程辅助类

来源：互联网发布：烟台龙口淘宝招聘网编辑：程序博客网时间：2024/06/06 00:14

最近博主写了一个Web API Client端的编程辅助类，我们可以用它在客户端层面调用Web API 完成CRUD操作。辅助类的Ajax请求是基于Jquery完成的，也就是说，大家在使用这个类的时候需要引用JQUERY，具体情况如下图所示：

JSHelper

var WEB_API_VERSION = "8.1";var JQUERY_URL = "/WebResources/new_jquery.1.11.js";function XrmHelper(){     var _clientUrl = Xrm.Page.context.getClientUrl();     this._webApiUrl = _clientUrl + "/api/data/v" + WEB_API_VERSION + "/";}XrmHelper.prototype.Create = function (url, content) {    var data = null;        $.ajax({        headers: { Accept: 'application/json', 'Content-Type': 'application/json; charset=utf-8', 'Content-Length': content != null ? content.length : 0 },        type: "POST",        url: url.indexOf("http") == -1 ? this._webApiUrl + url : url,        async: false,        cache: false,        data:content,        complete: function (context) {            if (context.status>=200 && context.status<300) {                try {                    data = context.getResponseHeader("OData-EntityId");                } catch (e) { }            }        }    });//ajax    return data;};XrmHelper.prototype.CreateAsync = function (url, content, callbackHandler) {    $.ajax({        headers: { Accept: 'application/json', 'Content-Type': 'application/json; charset=utf-8', 'Content-Length': content != null ?

Unit Test 代码

function xrmHelperUT() {    debugger;    //alert('onload');    var xrmHelper = new XrmHelper();    //test code    xrmHelper.Create("contacts", { "firstname": "hello", "lastname": "webapi" });    //create account    var entityUrl = xrmHelper.Create("accounts", "{'name':'create test account sync'}");    console.log(entityUrl + "create sync\n");        var entityAsyncUrl = null;    xrmHelper.CreateAsync("accounts", "{'name':'create test account async'}", function (result) {        entityAsyncUrl = result;        console.log(result+ "create async\n")    });    //read account    var createdAcc = xrmHelper.Read(entityUrl);    console.log(createdAcc.name+" Read \n");    var createdAccAsync = null;    xrmHelper.ReadAsync(entityAsyncUrl, function (result) {               console.log(result.name + " Read Async\n");    });    //update account    var uptsyncObj = "{ 'telephone1': '15000303158' }";     xrmHelper.Update(entityUrl, uptsyncObj);    console.log("update\n");    var uptAsyncObj = "{ 'telephone1': '15000303155' }";            xrmHelper.UpdateAsync(entityAsyncUrl, uptAsyncObj, function (c, r) {        console.log("update async\n");    })    //delete account    var isDeleted=xrmHelper.Delete(entityUrl);    console.log("delete "+isDeleted+" \n");    xrmHelper.DeleteAsync(entityAsyncUrl, function (isDeleted) {        console.log("delete " + isDeleted + " \n");    })    //execute API    //who am I    var userInfo=xrmHelper.ExecuteAPI("GET", "WhoAmI()", null);    xrmHelper.ExecuteAPIAsync("GET", "WhoAmI()", null, function (r) {        if (r != null)        {            console.log(r.UserId);        }    });}
