The invention provides a coding method for preventing URL arbitrary information acquisition attack on the internet, and crucially provides a digital code and character string code secret coding method based on rapid symmetric encryption coding through design Four rounds of encryption is performed on source digital codes by the coding method based on a set of independently designed rapid conversion and mixed encryption processing so that secret character string codes are obtained, and sensitive digital information in a URL is protected from being arbitrarily acquired and accessed. The method comprises the steps that encryption coding is performed on the sensitive digital information in the URL by a server side so that a public URL is generated; a user uses the public URL to transmit an access request; and when the server side reads the URL access request of the user, the server side firstly decodes secret character string parameters included in the access request and gives normal request response if the decoding result is correct, or regards the access request as illegal attack and does not give response, or performs other further processing. The method is high in coding and decoding speed and high in security intensity and has high capacity of preventing URL arbitrary access attack with no requirement for additional database comparison operation as for parameter tampering access attack in the URL so that realization efficiency is high.
