The invention discloses a breeze-type air outlet structure of an air conditioner. The breeze-type air outlet structure comprises an air outlet port formed in a shell body of the air conditioner, an air guide plate rotationally installed on the shell body of the air conditioner and matched with the air outlet port, and an air duct component arranged in the shell body of the air conditioner, whereinthe air duct component forms an air duct used for guiding air flow generated by the air conditioner towards the air outlet port; and a plurality of air outlet holes are formed in the air guide plate.The breeze-type air outlet structure is capable of enabling a part of air flow to penetrate through the air guide plate to be dispersed and flow out during air guide, and preventing the air flow fromflowing out around the air guide plate and from parts which do not need air outlet, of the air outlet port.

The invention discloses an air-conditioning system, a control method and a device for the air-conditioning system. The air conditioning system includes an outdoor heat exchanger, a first throttling device, and a refrigerant tank. All branches in the outdoor heat exchanger are divided into the first group of circuits and the second group of circuits; the refrigerant tank is located between the first throttling device and the outdoor Between the heat exchangers; the refrigerant tank includes: the first port is connected to the first throttling device for allowing the throttled refrigerant to enter the refrigerant tank for gas-liquid separation; the second port is connected to the first group of circuits for The separated gaseous refrigerant is transmitted to the first group of circuits; the third port is connected to the second group of circuits through a flow distribution component, and is used to transmit the separated liquid refrigerant to the second group of circuits. The present invention is provided with a refrigerant tank, and the throttled refrigerant in the heating mode enters the refrigerant tank to realize gas-liquid separation, and the separated gas refrigerant and liquid refrigerant are respectively transported to different branches of the outdoor heat exchanger to ensure that the outdoor heat exchanger The amount of refrigerant circulation in the medium ensures uniform liquid separation and improves heat exchange capacity.

The disclosure relates to an injection attack detection method, device, server and storage medium, and relates to the field of computer technology. This embodiment provides a method for detecting injection attacks that does not depend on regular expressions, by generating a query statement to be executed based on user input data, and obtaining context information of the query statement, according to the context information and the input data, detecting whether the processing logic of the query statement changes, and if it is detected that the processing logic of the query statement changes, it is determined that the query statement has an injection vulnerability, and the execution of the query statement is terminated. Through this detection method, the false positive rate and false negative rate can be reduced, and the accuracy of attack detection can be improved.

The present invention proposes an application program attack defense method and system based on code injection and behavior analysis. By injecting protection codes into applications that need protection, identifying attack behaviors in applications includes: injecting protection codes into applications that need protection Program, mount the hook point at the predetermined key call position, and the protection code monitors the marked parameters and the operation behavior of calling key functions in the application; run a unified protection plug-in, and conduct security risk analysis in combination with the operation behavior, marked parameters and context information , identify whether there is a suspicious webshell in the monitored code in the application program; send a corresponding alarm message according to the security risk analysis result, or directly block the operation of the application program. The above method can detect attacks and protect itself at runtime through reasonable deployment of protection codes, achieving fewer false negatives and false negatives, more comprehensive and accurate protection, and faster vulnerability response.

Disclosed herein are systems, methods, and non-transitory computer-readable media for enforcing application usage policies. As part of an application purchase transaction, the application distributor creates a unique proof of purchase receipt. This receipt can be bundled with the application and delivered to the purchaser. Each machine can maintain an authorization file that lists the users authorized to use applications on that machine. A system configured to practice the method verifies that a user is authorized to use an application on a machine based on an application proof of purchase receipt and the authorization file. If the application proof of purchase receipt and the authorization file are both valid, the system checks if the user account identifier in the receipt is contained in the authorization file. If so, the user can be considered authorized to use the application on the machine.

The present invention provides an application security protection method, an application client and an ACR server, wherein the application security protection method includes: sending application client information to the ACR server; receiving a random key sent by the ACR server and pre-stored The verification file list; according to the random key and the verification file list, encrypt the verification file list to generate the first encrypted information list; send the first encrypted information list to the ACR server for verification; when the ACR server verification passes Finally, generate and store the first access ID according to the first encrypted information list; when it is necessary to connect to the APP server, send the first access ID and the application client information to the APP server for verification. The embodiment of the present invention prevents hackers from obtaining sensitive information of the user or disseminating illegal information by cracking the application client by means of double verification, thereby protecting the information security of the user.

Disclosed is a small sewage precipitation device. The small sewage precipitation device is characterized by mainly comprising a vortex-shaped water channel upper cover (1), a container (2), a vortex-shaped water channel lower cover (3), a position adjusting barrel (5), handles (4 and 6) and sludge valves (7 and 8). The small sewage precipitation device is a miniaturized sewage treatment device, high in precipitation efficiency and low in costs.
