Kysl Haikang camera 8247 H9 ISAPI test

• We put h7 Of ky_ai After transplantation , Compile, package and import to the camera , And then isapi request , It is found that the correct result cannot be returned

GET /ISAPI/Custom/OpenPlatform/extern/ky_ai/ky_load_list.cgi?format=json

But we found that , It's not that it can't be connected , It's connected, and the returned result is incorrect

• hold h7 Of isapiExternDemo Get it, compile it, pack it and import it into the camera , Not good either. , Same as above
  

• stay h9 Found one in it http_proxy_demo, Test it , Notice adding ?format=json, Same old thing

Then check it out http_proxy_demo Source code , Added some printing information

It is found that the initialization and registration are successful , But received isapi Requests just can't get into the code .... If you enter , At least the requested information will be printed

20220706 Zhu Gong said it was their problem , Gave one to libopdevsdk.so To come over , Let's copy it into the camera

use ssh Connect the camera ,

Then input debug,

Then put the generated code BQAAAIB8YvdrmbC8N0I= Send it to Zhu Gong ,

Zhu Gong returns the password 0wmA25sgRVMD2QYfcoFR4er45kC0b/cfE7CB+4H0bIod0vv8/y8u4BX2Bo58gtJ2Eq89bEaE2oNBE/VPMBSqr40VSDfbZkoH5xUpoV11392UjboukooqcS62TC4Qil9GRTmP+AgWp6+nmu8Hzjhu8T7r6c1ySDoCU22OE+eJu5M=,

Then go in and we create it in the root directory ky_userdata Catalog

perform mount -t nfs -o nolock 192.168.1.117:/root/heop_devel_kit/volume /ky_userdata Mount to our ubuntu in ,

And then we put libopdevsdk.so Copy in , Replace /lib/libopdevsdk.so（ Be careful not to change permissions ）

Then cancel the mount （ If you don't cancel , Once the camera hangs , The consequences are serious ）

umount /ky_userdata/

And then quit

Then import app, start-up , use postman call isapi Interface , Find out

Let's replace this .so The file is only temporary , In the future, we need to upgrade the firmware of Hikvision
