k3 Cloud webservice json PHP 调用问题

做了一个小程序测试通过 PHP 调用 JSON.
basic auth 没有问题，
web service 发布没有问题

连接没问题
cookie 没问题

但是， 返回 ctx == null 的错误。

{"ErrorCode":"Exception","Message":"{ctx == null}","StackTrace":"[PUR_Requisition_View: 2014/12/31 11:15:11]:\n[REQUEST: {CreateOrgId:0,Number:CGSQ000042,Id:}]System.Exception: {ctx == null}

========================================
如果在浏览器中先连一次
192.168.50.178/K3CloudServiceInterface/json/syncreply/PUR_Requisition_View

感觉像是激活一下， 再通过 php restful client 就能够获得希望的结果， 比如

[code] [response] => {"Result":{"FID":100009,"FBillNo":"FO00000008","FForeOrgId":{"FOrgID":0,"FNUMBER":"101.2","FNAME":"\u603B\u88C5\u4E8B\u4E1A\u90E8"},"FBillTypeID":{"FNumber":"YCD01_SYS","FName":"\u666E\u901A\u9884\u6D4B\u5355"},"FDate":"\/Date(1419944400000+1100)\/","FDocumentStatus":"C","FDescription":"","FCreatorId":{"FUserID":0},"FCreateDate":"\/Date(1419989823000+1100)\/","FModifyDate":"\/Date(1419989847000+1100)\/","FApproverId":{"FUserID":0,"FName":"zuyi Wang"},"FModifierId":{"FUserID":0},"FApproveDate":"\/Date(1419992160950+1100)\/","FCancelStatus":"A","PLN_FORECAST__FEntity":[{"FEntryID":100013,"FMaterialID":{"FMATERIALID":0,"FNumber":"1000003"},"FUnitID":{"FUNITID":0,"FNumber":"Pcs","FName":"Pcs","FPrecision":0},"FQty":10.0000000000,"FStartDate":"\/Date(1419944400000+1100)\/","FEndDate":"\/Date(1419944400000+1100)\/","FCloseStatus":"A","FMtoNo":" ","FBaseUnitID":{"FUNITID":0,"FNumber":"Pcs","FName":"Pcs","FPrecision":0},"FBaseQty":10.0000000000,"FBaseOrderQty":0,"FBaseWriteOffQty":0,"FReserveType":"1","FPriority":0,"FWriteOffQty":0,"FOrderQty":0,"FRemark":"","PLN_FORECAST__FEntity_Link":[]}]}}[/code]
