用友U8二次开发调用API通用解决方案
用友U8的二次开发,有一个重要的功能就是调用U8的API,生成或者审核U8的业务单据.当然这些单据可以直接通过写数据库的方式,直接插入或者更新数据表也能达到预期.但除非非常熟悉用友数据表的逻辑,否则这种直接写数据库的方式,有诸多风险,比如数据逻辑错误,关联错误等等.本文提供一以一种通用的API调用方式,避免受客户端环境(比如是否安装用友,用友的版本约束等)影响.估计有反应快的同学已经猜到,通过在服

用友U8的二次开发,有一个重要的功能就是调用U8的API,生成或者审核U8的业务单据.当然这些单据可以直接通过写数据库的方式,直接插入或者更新数据表也能达到预期.但除非非常熟悉用友数据表的逻辑,否则这种直接写数据库的方式,有诸多风险,比如数据逻辑错误,关联错误等等.
本文提供一以一种通用的API调用方式,避免受客户端环境(比如是否安装用友,用友的版本约束等)影响.估计有反应快的同学已经猜到,通过在服务器部署WebService或者WebAPI接口的方式,提供给客户端调用就可以实现这个方案.
做过用友U8二次API开发的同学们都知道,调用用友API的首先的先决条件是登录系统,获得U8Login对象,这个对象是通过登录用友后获得的.主要的参数可以参考U8发布出来的通用文档.这个地方就不多说.(注意:在u816以后,API调用的方式将被限制,不购买OpenAPI授权下,是不能调用API方式写入单据.直接写数据库的方式请参考我后续发布的文章)
1.打开 VS2019,创建一个WebService,或者AspMVC程序都行,反正能提供给客户端调用的接口的程序类型都行
2.要创建U8Login对象,需要在项目中引用以下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对象的的代码如下具体
/第一步：构造u8login对象并登陆(引用U8API类库中的Interop.U8Login.dll)
//如果当前环境中有login对象则可以省去第一步
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对象可以在调用的时候建立,或者在Web应用程序初始化的建立,作为全局对象保存,需要的时候直接使用.另外,透露一个U8的秘密,对于从IIS进程,JAVA进程发起的Login请求,U8是不校验U8Login对象是否是调试版的U8Login.
3.拿到U8Login对应以后,就可以调用U8API了.具体API的声明以及参数使用,参考用友的API资源管理器中的范例,此处用一个范例说明(销售发货单)
//第二步：构造环境上下文对象，传入login，并按需设置其它上下文参数
U8EnvContext envContext = new U8EnvContext();
envContext.U8Login = u8Login;
//销售所有接口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：单据类型
//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：构造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参数均按引用传递
//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())
