Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The embodiments of the present invention, and all other embodiments obtained by a person of ordinary skill in the art without any inventive step, are within the scope of the present invention.
In order to overcome the above problems in the prior art, embodiments of the present invention provide a method and an apparatus for transmitting a weather data file, where the server and the client communicate (including data transmission) based on an https protocol, and a format of a protocol header (abbreviated as https protocol header) of the https protocol is defined in advance, so as to perform authentication according to the protocol header of the https protocol, thereby implementing secure transmission of the weather data file.
To facilitate an understanding of the various embodiments of the present invention, a power prediction system is described below.
The power prediction system may include three regions: the system comprises a meteorological data file transmission area, a first safety area and a second safety area. Unidirectional data transmission exists between the meteorological data file transmission area and the second safety area; there is data transfer between the first secure area and the second secure area.
The weather data file transmission area may include a weather server, a numerical weather forecast server, and a reverse isolation device. And the numerical weather forecast server is used for storing the weather data obtained by weather forecast in a form of a weather data file. And the weather server is used for loading and unloading the weather data file from the numerical weather forecast server. Data transmission between the weather server and the numerical weather forecast server may be performed through the Internet (Internet). The reverse isolation device, such as a gatekeeper, is used for reverse isolating the weather data file transmission area from the second security area, i.e. only allowing the second security area to obtain data from the weather data file transmission area, but not allowing the second security area to write data into the weather data file transmission area.
The devices in the first security zone can be connected through a private network, and the private network has higher security relative to the internet, so the first security zone can be called. The first security area may include an EMS (Energy Management System) database.
The devices in the second security zone can be connected through a private network, and the private network has higher security relative to the internet, so the second security zone can be called. The second safe zone may include a forecast system work machine, a forecast system backup machine, a data collection server, and a workstation. The prediction system standby machine, the data acquisition server and the workstation are respectively connected with the prediction system working machine. The prediction system working machine is connected with the reverse isolation device to obtain a meteorological data file; the prediction system worker obtains EMS data from an EMS database. And a firewall is further included between the first safety zone and the second safety zone, and particularly, the firewall is deployed between the prediction system working machine and the EMS database. The data collection server is used for storing other data required by power prediction besides the meteorological data and EMS data. And the user calls a prediction system working machine through the workstation to perform power prediction on the new energy power plant according to the meteorological data, the EMS data and other data. When the working machine of the prediction system can not normally carry out power prediction, the standby machine of the prediction system carries out power prediction.
The meteorological data file transmission in the embodiments of the invention refers to a process that a meteorological server carries meteorological data files up and down from a numerical weather forecast server. In the following examples, the server is an https server and an index value weather forecast server; the client is an https client and refers to a meteorological server.
Fig. 1 is a schematic flow chart of a meteorological data file transmission method according to an embodiment of the invention. As shown in fig. 1, a meteorological data file transmission method includes: step S101, receiving a meteorological data file downloading request sent by a client, and authenticating the client according to an https protocol header carried by the meteorological data file downloading request; the format of the https protocol header is predefined; the https protocol header includes account authentication information, target file information, and the number of current attempts to download the target file.
It should be noted that the main execution body of the meteorological data file transmission method provided by the embodiment of the present invention is a server.
It should be noted that, the format of the https protocol header on which communication (including data transmission) between the server and the client is based is customized in advance. The format of the custom https protocol header includes account Authentication information (Authentication), target file information (TargetFileInfo), and the number of current attempts to download the target file (AttemptTimes). The account authentication information, the target file information and the current number of attempts to download the target file are all variables.
The account authentication information refers to information for authenticating the client. Account authentication information may include a username, password, and other authentication information.
And the target file refers to the meteorological data file requested to be downloaded by the client. The object file information, which refers to information related to the object file, may include, but is not limited to, the name, size, MD5 value, etc. of the object file.
The number of current attempts to download the target file refers to the total number of times the client has requested the target file to be downloaded (this time containing the currently transmitted request for downloading the weather data file).
The http Protocol (Hypertext Transfer Protocol over Secure Socket Layer or Hypertext Transfer Protocol Secure) is an http channel targeted for security, and may be understood as a Secure version of http. Namely http, adding an SSL (Secure Socket Layer) Layer, the Secure basis of httpS is SSL, which relies on certificates to verify the identity of the server and encrypt the communication between the browser and the server. Therefore, compared with the communication based on the http protocol, the communication based on the https protocol is safer and more reliable.
The weather data file downloading request refers to a request sent by a client for downloading a target file from a server.
The weather data file downloading request and the response of the client to the weather data file downloading request both comprise https protocol headers.
After the server receives the download request of the weather data file, the account authentication information, the target file information and the current download attempt times of the target file can be obtained according to the https protocol header carried by the download request.
And after the account authentication information is obtained, authenticating the client according to the account authentication information.
Step S102, if the authentication fails, judging whether the times of the authentication failure of the client in a preset time period reach a preset maximum time; if not, judging whether a preset forced downloading condition is met or not according to the current trial downloading times of the requested target file; if yes, allowing the client to download the target file; and if not, not allowing the client to download the target file.
Specifically, if the authentication fails, that is, the authentication fails, it is determined whether the incorrect authentication window overflows.
The overflow of the false authentication window refers to that the number of times of the failed client authentication in the preset time period reaches the preset maximum number of times. For example, client a fails authentication 10000 times in 3 hours.
If the error authentication window does not overflow, namely the number of times that the client authentication fails does not reach the preset maximum number of times, continuously judging whether the preset forced downloading condition is met.
And the preset forced downloading condition is that whether the current attempted downloading frequency of the target file is a preset frequency or not. The preset number is a specific number.
For example, the preset number of times is 6, if the previous 5 times of downloading of a certain file fails, the 6 th time requests to download the file, and if the authentication fails and the number of times of failing does not reach the preset maximum number of times, the preset forced downloading condition is met; and if the previous 4 times of downloading of a certain file fail, requesting to download the file for the 5 th time, and if the authentication fails and the number of times of failure does not reach the preset maximum number, not meeting the preset forced downloading condition.
And if the preset forced downloading condition is met, the server side allows the client side to download the target file.
The forced downloading condition is preset to prevent the new energy power plant from missing the optimal downloading time due to authentication errors caused by some reasons, so that the new energy power plant can also download the meteorological data file under the condition, even if the data is stolen, only a small amount of data is needed, and the influence can be ignored.
If the preset forced downloading condition is not met, the server side does not allow the client side to download the target file, and informs the client side, and the client side can continuously try to download the target file because the error authentication window does not overflow.
It should be noted that the server also sends a download response to the client to notify the client of the result of determining whether the incorrect authentication window overflows.
The embodiment of the invention realizes the downloading of the meteorological data file based on the https protocol, determines whether to allow downloading according to whether the error authentication window overflow and forced downloading conditions are met, and can ensure the authenticity and integrity of the meteorological data file by combining the modern transmission technology and the corresponding safety strategy, safely and stably transmit the meteorological data file and improve the transmission safety of the meteorological data file. Furthermore, the power prediction progress can be mastered in real time, and the accuracy of the power prediction of the new energy power plant is guaranteed.
Based on the content of the foregoing embodiments, after determining whether the number of times that the authentication fails within the preset time period reaches the preset maximum number of times, the method further includes: and if so, rejecting all weather data file downloading requests of the client.
Specifically, if the error authentication window overflows, all weather data file downloading requests of the client are rejected.
And all the meteorological data file downloading requests of the client comprise the meteorological data file downloading request of the client at this time and the meteorological data file downloading requests of each time after this time.
The method can reject all weather data file downloading requests sent by the IP address in a mode of closing the IP address used by the client from the application layer, and realize rejection of all weather data file downloading requests of the client, but is not limited to the mode.
The application layer, which refers to the seventh layer of the seven-layer OSI model, directly provides services for application processes, and has the function of completing services required by a series of business processing while realizing the mutual communication of a plurality of system application processes. The https protocol belongs to the application layer protocol.
The embodiment of the invention can improve the safety of meteorological data file transmission by rejecting all meteorological data file downloading requests of the client under the condition that the error authentication window overflows.
Based on the content of the foregoing embodiments, after authenticating the client, the method further includes: if the authentication is passed, judging whether the target file exists according to the target file information; and if so, allowing the client to download the target file.
Specifically, if the client passes the authentication, it is determined whether the target file requested to be downloaded by the client exists in the server according to the target file information, that is, whether the target file exists (exists) in the server is determined.
And if the target file exists on the server, allowing the client to download the target file.
The embodiment of the invention realizes the downloading of the meteorological data file based on the https protocol, can ensure the authenticity and integrity of the meteorological data file, transmits safely and stably, and can improve the safety of meteorological data file transmission.
Based on the content of the foregoing embodiments, after determining whether the target file exists according to the target file information, the method further includes: and if the target file does not exist, sending a downloading response to the client to inform the client that the target file does not exist.
Specifically, the download response refers to a response of the client to the weather data file download request.
The https protocol header may also include a status code (StatusCode). The status code is used for describing the downloading status of the meteorological data file, and can be used for describing whether to resume transmission at a breakpoint, whether a target file exists, whether a password is wrong or not and the like. The state code is a variable.
Because the download response also carries the https protocol header, if the target file does not exist, the state code in the https protocol header carried by the download response can be modified to the state code in which the target file does not exist, and the download response is sent to the client. After receiving the download response, the client can know that the target file of the request does not exist according to the download response, and continue to request to download the target file in the subsequent requests.
It should be noted that the client download request is subject to the configuration of the time period. There are two basic types of meteorological data files: the first is a meteorological data file for short term power prediction, this kind of file is typically one a day; the second is a meteorological data file for ultra-short term power prediction, which is typically one every several minutes (e.g., one every 15 minutes). The downloading time period can be configured aiming at the meteorological data files, and the downloading time period can be configured to be one hour for the first meteorological data file; for the second type of meteorological data file, it may be configured to be the same as the generation interval of the file (e.g., 15 minutes). Because the meteorological data file is important to power prediction, and the server and the client do not know when the target file appears on the numerical weather forecast server, the client can continuously request to download the target file if the client knows that the target file requested at this time does not exist in the configured downloading time period; outside the configured downloading time period, if the client knows that the target file requested this time does not exist, the client does not request to download the target file any more, and when the next downloading time period comes, whether the weather data file requested to be downloaded at this time is a new target file or not is judged according to the information such as the name and/or the MD5 value of the weather data file requested to be downloaded at this time.
The embodiment of the invention ensures that the client side continuously initiates the downloading request of the target file in the configured downloading time period by judging whether the target file exists or not and informing the client side when the target file does not exist, thereby ensuring that the target file can be downloaded to a required meteorological data file more possibly.

If the authentication fails, judging whether the times of the client end failing to pass the authentication in the preset time period reach the preset maximum times, and informing the client end of the judgment result whether the error authentication window overflows or not through a download response sent to the client end.
And S202, receiving the judgment result, if the judgment result is not reached, adding 1 to the total trial download frequency of the target file, taking the new total trial download frequency of the target file as the new current trial download frequency of the target file, and generating a new meteorological data file download request.
After the client receives the judgment result, if the judgment result is not reached, the error authentication window is not overflowed, and the downloading instruction can be continuously initiated because the meteorological data file downloading request is not allowed. The specific process of continuing to initiate the downloading instruction may include: adding 1 to the current trial download times (AttemptTimes) of the target file to serve as the current trial download times (AttemptTimes) of the target file in the https protocol header carried by the next meteorological data file download request, generating the next meteorological data file download request, returning to the step of sending the meteorological data file download request, and requesting to download the target file again.
The embodiment of the invention realizes the downloading of the meteorological data file based on the https protocol, determines whether the downloading is allowed according to whether the error authentication window overflow is met, and can ensure the authenticity and integrity of the meteorological data file by combining the modern transmission technology and the corresponding safety strategy, safely and stably transmit the meteorological data file and improve the transmission safety of the meteorological data file. Furthermore, the power prediction progress can be mastered in real time, and the accuracy of the power prediction of the new energy power plant is guaranteed.
Based on the content of the foregoing embodiments, after receiving the determination result, the method further includes: and if the judgment result is achieved, notifying a preset worker.
Specifically, after the client receives the judgment result, if the judgment result is reached, it indicates that the error authentication window overflows, and an error occurs in a certain link in the meteorological data file transmission, and the error needs to be processed by a worker, so that the client can notify a predetermined worker by sending a short message, an instant messaging message, an email, and the like. The predetermined staff member can receive the notification through a terminal such as a mobile phone, a computer, or the like and perform processing in real time.
