用友U8的二次开发具有调用的重要功能U8的API,生成或审核U8的业务单据.当然，这些文件可以通过写数据库直接插入或更新数据表达到预期.但是，除非您非常熟悉用友数据表的逻辑，否则直接编写数据库的风险很大，如数据逻辑错误、关联错误等.
本文提供了一种通用性API调用方法，避免受客户环境(如是否安装用友、用友版本约束等)的影响。.据估计，反应迅速的学生已经猜测，通过部署服务器WebService或者WebAPI该方案可以通过向客户端提供接口调用来实现.
做过用友U8二次API开发的学生都知道，打电话给朋友API第一个先决条件是登录系统并获得它U8Login对象，这个对象是登录用友后获得的.可参考主要参数U88发布的通用文档.这个地方就不多说了.
1.打开 VS2019,创建一个WebService,或者AspMVC可以提供给客户端调用的接口的程序类型
2.要创建U8Login项目中需要引用以下对象dll
UFIDA.U8.MomServiceCommon.dll
UFIDA.U8.Portal.Common.dll
UFIDA.U8.Portal.Framework.dll
UFIDA.U8.Portal.Proxy.dll
UFIDA.U8.U8APIFramework.dll
UFIDA.U8.U8MOMAPIFramework.dll
UFSoft.U8.Framework.Login.UI.dll
生成U8Login对象的代码如下
/第一步：结构u8login并登录对象(引用)U8API类库中的Interop.U8Login.dll) //如果在当前环境中login对象可以节省第一步 U8Login.clsLogin u8Login = new U8Login.clsLogin(); String sSubId = "AS"; String sAccID = ConfigurationManager.AppSettings["sAccID"].ToString(); String sYear = DateTime.Today.Year.ToString(); String sUserID = ConfigurationManager.AppSettings["sUserID"].ToString(); String sPassword = ConfigurationManager.AppSettings["sPassword"].ToString(); String sDate = DateTime.Today.ToString("yyyy-MM-dd"); String sServer = ConfigurationManager.AppSettings["sServer"].ToString(); String sSerial = ""; if (!u8Login.Login(ref sSubId, ref sAccID, ref sYear, ref sUserID, ref sPassword, ref sDate, ref sServer, ref sSerial)) { resp.resp = "fail"; resp.msg = "登陆失败，原因：" u8Login.ShareString; result = "{\"resp\":\"" resp.resp "\",\"msg\":\"" resp.msg "\",\"retcode\":\"" dmlist.cDLCode "\"}"; return false; } U8Login调用时可以建立或建立对象Web应用程序初始化的建立作为全局对象保存，必要时直接使用.另外，透露一个U8的秘密，从IIS进程,JAVA进程发起的Login请求,U8是不校验U8Login对象是否为调试版U8Login.
3.拿到U8Login对应后，可调用U8API了.具体API参考用友的声明和参数使用API这里用一个例子来解释资源管理器中的示例
//第二步:构造环境中上下文对象的引入login，并根据需要设置其他上下文参数 U8EnvContext envContext = new U8EnvContext(); envContext.U8Login = u8Login; //销售界面均支持内部独立事务和外部事务，默认内部事务 ///如果是外部事务，则需要传递ADO.Connection对象，并将IsIndependenceTransaction属性设置为false //envContext.BizDbConnection = new ADO.Connection(); //envContext.IsIndependenceTransaction = false; //设置上下文参数 envContext.SetApiContext("VoucherType", VoucherType); /上下文数据类型：int，含义：文件类型 //第三步：设置API地址标识(Url) //当前API：新增或修改的地址标识为：U8API/Consignment/Save U8ApiAddress myApiAddress = new U8ApiAddress(cAds); //第四步：结构APIBroker U8ApiBroker broker = new U8ApiBroker(myApiAddress, envContext); //第五步：API参数赋值 //给BO表头参数domHead赋值，此BO参数的业务类型为发货单，属表头参数。BO参数按引用传递 提示:给BO表头参数domHead赋值有两种方法 ///方法一是直接传入MSXML2.DOMDocumentClass对象 //broker.AssignNormalValue("domHead", new MSXML2.DOMDocumentClass()) ADODB.Connection conn = new ADODB.ConnectionClass(); ADODB.Recordset rs = new ADODB.RecordsetClass(); MSXML2.DOMDocument domhead = new MSXML2.DOMDocumentClass(); string strConn = string.Format("Provider=SQLOLEDB;Initial Catalog={0};Data Source={1};", ConfigurationManager.AppSettings["sDBname"].ToString(), u8Login.dbServerName); conn.Open(strConn, "sa", u8Login.SysPassword, 0); string sql = "select * from Sales_FHD_T where 1=0"; rs.Open(sql, conn, ADODB.CursorTypeEnum.adOpenForwardOnly, ADODB.LockTypeEnum.adLockOptimistic, -1); rs.Save(domhead, ADODB.PersistFormatEnum.adPersistXML); U8APIHelper.FormatDom(ref domhead, "A"); broker.AssignNormalValue("DomHead", domhead); domhead.selectSingleNode("//rs:data/z:row").attributes.getNamedItem("cdlcode").nodeValue = dmlist.cDLCode; domhead.selectSingleNode("//rs:data/z:row").attributes.getNamedItem("ddate").nodeValue = dmlist.dDate; domhead.selectSingleNode("//rs:data/z:row").attributes.getNamedItem("cbustype").nodeValue = dmlist.cSTCode == "03" ?
