The invention discloses a public mobile APP data capturing method which is characterized by comprising the following steps: S1, starting an agent service, and setting a firewall open monitoring port;S2, establishing a mobile phone equipment operation environment, starting a remote monitoring service, regularly starting an agency service and an application barrier-free service authority, setting amobile phone equipment agency, and verifying network communication; S3, starting a back-end service and a data caching service; S4, starting a gesture simulation program, waiting for an APP data network request, and checking a back-end log processing result; and S5, opening a remote monitoring service page of the mobile phone equipment by using a browser, checking the current running program of the mobile phone equipment, and monitoring the state of the mobile phone equipment. The method has the advantages that data of an App application can be captured, user behaviors and gestures can be simulated, the data can be automatically triggered, and meanwhile, mobile phone information can be collected and a mobile phone state can be reported; when an application fault occurs, the mobile phone can be remotely operated, and the operation and maintenance cost is reduced.
