通过集成自定义API上传附件到单据（参考）

1 业务背景

外部通过接口上传附件到星瀚，并且将附件绑定到指定单据。

适用者：集成中高级开发，熟悉集成自定义API和集成服务流程。

使用帮助手册查看DataFile.uploadAndBind和executeServiceFlow和$action

2 解决方案

2.1 方案总述

通过配置集成自定义API，接受外部传入附件，通过固定脚本样式解析字节数组，然后通过DataFile.uploadAndBind绑定到指定单据。下面会有逐行注释解析和使用注意事项。

2.2 实现步骤

var file = FastJsonParse(FastJsonFormat(REQ));//反序列化解析REQ，保存文件上下文。REQ是自定义API输入
var content = Base64Decode(file.fileData);//通过Base64解码文件内容
var fileName= file.fileName;    
var map={
  "entityName":"isc_demo_basedata_1",
  "entityPk":2022614386333507584,//绑定单据ID，如果单据在系统中还未生成，通过$action字段保存，如果很复杂则通过executeServiceFlow同步调用服务流程，处理好单据生成后将单据id返回
  "field":"attachmentpanelap",
  "fileName":fileName,
  "content":content,
  "appId":"iscb",
  "formId":"isc_demo_basedata_1"
};
var result = DataFile.uploadAndBind(map);

注意：未标注注释行参考帮助手册，附录提供自定义API供参考。PostMan调试参考
