pb9 posturl 返回-6怎么解决
li_port = Integer(st_hosptial.port)
lblb_args = Blob(ls_args)
ll_length = Len(lblb_args)
ls_header = "Content-Type: application/json~n" + "Content-Length: " + String( ll_length ) + "~n~n"
li_rc = iinet_base.PostURL(ls_url, lblb_args, ls_header, li_port, lobj_nif)
有时正常 单常常返回-6 是什么问题呢
