## Java sdk调用附件上传接口
**产品版本说明**
金蝶云星空产品版本为：补丁版本为PT146897【7.7.2374.8】及以上
**使用说明**
1、调用单据工序汇报保存接口，后面会用到单据的FID,FBillNo
```
{
"Result": {
"ResponseStatus": {
"IsSuccess": true,
"Errors": [],
"SuccessEntitys": [{
"Id": 100028,
"Number": "GXHB0056",
"DIndex": 0
}],
"SuccessMessages": [],
"MsgCode": 0
},
"Id": 100028,
"Number": "GXHB0056",
"NeedReturnData": [{}]
}
}
```
返回结果中，Id为单据FID,Number为FBillNo
2、上传附件接口(上传附件并绑定单据)
参数说明：
注意：如果是单据头附件，EntryinterId要么不填，要么填-1。
请求示例：
```
K3CloudApi api = new K3CloudApi();
String FID="";//单据内码FID
String FBillNo="";//单据编号FBillNo
String jsonData =
"{\"FileName\":\"test.txt\",\"FEntryKey\":\"\",\"FormId\": \"SFC_OperationReport\",\"IsLast\": true," +
"\"InterId\": " + FID + "," + "\"BillNO\": " + "\"" + FBillNo + "\"" +
",\"AliasFileName\": \"test\",\"SendByte\": \"6L+Z5piv5rWL6K+V5paH5KMYmFzZTY05a2X56ym5Liy5LqS6L2s\"}";
String resultJson = api.AttachmentUpLoad(jsonData);
```
3、上传附件成功后，返回结果会有FileId返回
```
{
"Result": {
"ResponseStatus": {
"IsSuccess": true,
"Errors": [],
"SuccessEntitys": [{
"Id": 140561,
"Number": null,
"DIndex": 0
}],
"SuccessMessages": [],
"MsgCode": 0
},
"FileId": "723eea11a0e94a90892f7a47c93e",
"Message": ""
}
}
```
4、使用FileId，放置到单据保存接口，附件字段里，最后附件上传成功！
麻烦问一下有大文件上传的示例代码吗？
上传不成功
