Embodiment approach
[0029] As an implementation, the server generates a two-dimensional code that carries the URL information of the target merchant and an encrypted string of identity information, and the encrypted string of identity information includes a random number of characters and a multi-digit random string in its own dictionary. md5 value.
[0030] In this embodiment, the two-dimensional code satisfies: http: / / business website / encrypted string, that is, the URL corresponding to http: / / business website / encrypted string generates the two-dimensional code. Encrypted string generation algorithm: encrypted string = multiple random characters in your own dictionary + md5 value of multiple random strings. The commodity corresponding to each two-dimensional code is identified according to the difference in the encrypted string.
[0031] Step S102, the server sends the two-dimensional code to the target product.
[0032] As an implementation manner, the two-dimensional code may be sent to a prin...

The embodiment of the invention discloses a commodity recalling method and device based on the IOT (Internet of Things), and belongs to the technical field of the IOT. The method comprises the steps:generating QR codes through a server, and transmitting the QR codes to target commodities, so as to enable each QR code to be corresponding to one target commodity, wherein the QR codes record the identity information of the target commodities, and the identity information can be edited and modified at any time through the server. Therefore, the method enables a merchant to monitor and modify thestate of the commodity at any time. When the server obtains an operation instruction that a user scans the QR code on the target commodity, the user can obtain the latest information of the commodityin the first time, thereby achieving the recalling of the commodity, effectively saving the manpower, and enabling each user to check the information of the commodity in the above mode through scanning the QR code, achieving the precise recalling of the commodity, and effectively solving a problem that the recalling information of the commodity cannot be transmitted to the user because the contactinformation of the user is lost.
Description
technical field [0001] The present invention relates to the technical field of the Internet of Things, in particular to a method and device for recalling goods based on the Internet of Things. Background technique [0002] Existing product recalls are either manually contacting consumers who have reserved contact information, or publishing recall notices in newspapers and other media, and consumers contact manufacturers after seeing the notices, but no matter which recall method cannot be accurate All products recalled. Therefore, there is a technical problem that the product cannot be recalled accurately in the prior art. Contents of the invention [0003] The commodity recall method and device based on the Internet of Things provided by the present invention aim to improve the above-mentioned technical problems. [0004] A commodity recall method based on the Internet of Things provided by the present invention is applied to a server, and the method includes: the serve...
