我已经在阿里云平台上配置好了升级的bin文件包，云服务器发送的消息是：+QMTRECV: 0,0,"/ota/device/upgrade/i7pjRTDym9X/CP000001","{“code”:“1000”,“data”:{“size”:3072,“sign”:“c2facc4645e6d54d2be982670586d770”,“version”:“1.1”,“signMethod”:“Md5”,“url”:"https://iotx-ota.oss-cn-shanghai.aliyuncs.com/ota/6c26a97f8a7f71458ecffbbd301e0f1e/clfrwrujy00003n90qh9meqzx.bin?Expires=1681031545&OSSAccessKeyId=LTAI4G1TuWwSirnbAzUHfL3e&Signature=3IZ2c9svbQzQX%2BV07ar%2FRjqi8wI%3D",“md5”:“c2facc4645e6d54d2be982670586d770”},“id”:1680945145182,“message”:“success”}"
然后我现在需要获取这个url地址中的bin文件包，请问我该用什么指令呢，什么格式
