Internetwork interface calling method and device based on physical isolation

The invention discloses an inter-network interface calling method and device based on physical isolation, and the method comprises the steps: enabling a request server to analyze and recombine a first HTTP request obtained through a unified calling interface into a data structure body, and storing the data structure body into a temporary file; the first HTTP request is sent to the receiving server through the FTP channel according to the address of the unified calling interface of the receiving server contained in the first HTTP request, after the receiving server receives the temporary file, the temporary file is analyzed and assembled into a second HTTP request, request result information is obtained according to the actual request address in the second HTTP request, the request result information is stored in the temporary file, and the temporary file is sent to the receiving server according to the address of the unified calling interface of the receiving server. And sending to a request server. And forwa
