【电子回单】招行云直连-扫描调度解压文件失败，导致任务结果显示空
1、问题描述
如下图所示，招行银行云直连的回单任务，预处理完成之后，查看【详情】可以看到文件名。但是等任务下载完成之后，扫描调度结束，点【结果】看到的结果为空。
2、分析解答
通过回单日志看到，在预处理阶段，通过文件下载url（专线访问地址）将回单文件7xxxxxxxxxxxxx42023070811679431992619302912.zip下载到\tempPath\CMB_CMP下，然后又将其移动到\scanPath\CMB_CMP下。
在扫描调度阶段，对scanPath\CMB_CMP下的文件7xxxxxxxxxxxxx42023070811679431992619302912.zip进行解压，报错java.io.IOException: Negative seek offset（见附件）。
在预处理完成后，到\tempPath\CMB_CMP目录下找到下载后的文件，如下：
把这个文件拿过来，双击解压，报错了，如下：
检查配置上都没有问题，但从预处理调度的日志看到互联网访问链接是专线访问；但与现场了解到，该客户的银企服务器和银行服务器之间并没有架设专线，所以怀疑是这里回单文件下载URL有问题。查看接口文档，回单异步打印结果查询（DCTASKID）接口的请求报文字段文件地址类型qwenab的描述如下：
true或者空：生成的url链接为互联网可访问
false：生成的url链接为专线访问地址，（请专线接入客户该值传false）
因此，在银行配置页面将“是否为互联网访问链接”设置为“true”后，再重新下载任务。
待扫描调度结束后，查看【结果】，可以看到扫描结果正常显示了，如下图：
