| A local HTTP server for Android OTA package generation. |
| Based on OTA_from_target_files.py |
| |
| Usage:: |
| python ./web_server.py [<port>] |
| |
| API:: |
| GET /check : check the status of all jobs |
| GET /check/<id> : check the status of the job with <id> |
| GET /file : fetch the target file list |
| GET /download/<id> : download the ota package with <id> |
| POST /run/<id> : submit a job with <id>, |
| arguments set in a json uploaded together |
| POST /file/<filename> : upload a target file |
| [TODO] POST /cancel/<id> : cancel a job with <id> |
| |
| Other GET request will be redirected to the static request under 'dist' directory |
