Detailed Description
To further illustrate the various embodiments, the invention provides the accompanying drawings. The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the embodiments. Those skilled in the art will appreciate still other possible embodiments and advantages of the present invention with reference to these figures. Elements in the figures are not drawn to scale and like reference numerals are generally used to indicate like elements.
The invention will now be further described with reference to the accompanying drawings and detailed description.
Referring to fig. 1, fig. 1 is a flowchart of a method for unified data exchange according to an embodiment of the present invention, where the method for unified data exchange includes the following steps:
in the first step: the data service provider creates application information for providing data services on a data exchange platform, and creates corresponding parameter information under the application information one by one, wherein the related application information comprises an application name, an interface service domain name, an interface service application name, application function description of the application and the like, and the parameter information comprises related information such as data service name data service entry parameters, data service exit parameters, data service addresses, data service protocol types, HTTPS private certificates, test sample data and the like.
In the second step: the data service accessor submits an interface application for accessing the data service provider to the data exchange platform, specifically, after determining the requirement, the data service accessor applies for the required interface service to the data exchange platform according to the requirement of a service scene, and registers an interface service access public key if the application is passed; the private key signature of the key pair is used for forming a signature field, meanwhile, the certificates APPID and APPSECRET issued by the data exchange platform are submitted for continuing to access the data exchange platform, the process is similar to the process that people surf the internet at ordinary times to access any website needing to be registered, an application is issued, the website is clicked, if more contents need to be browsed, a new user needs to be registered, and after the website passes the verification and is successfully registered, the ID and the password of the individual user are obtained. For example, a platform integrator is taken as an example, wherein the platform integrator may be a data service visitor or a data service provider. When the platform integrator is registered in the application, a public and private key pair needs to be generated, the private key is held by the platform integrator, and the public key needs to be provided to the data exchange platform. In order to confirm that the two parties of data interaction are effective, the data exchange platform provides the following mechanisms:
when the data service access provider data exchange platform is used, a signature field needs to be provided for the data exchange platform, the data exchange platform verifies that a data packet submitted by the data service access provider is legal according to the signature field, and a public and private key pair is involved on the side; and meanwhile, when the data exchange platform responds to the data, the signature field of the response data is signed so that a data service visitor can verify the reliability of the data source, and the public and private key pair of the data exchange platform is independently used for responding to the data service and can be downloaded when the platform integrator is integrated. The public and private keys are public and private keys of SHA256WithRSA, and the platform integrator can generate a public and private key pair by itself or generate downloading by using a tool provided by a data exchange platform.
In step three: and the data exchange platform tests the interface application according to the parameter information, if the test is successful, the interface configuration is completed to access the data service provider, otherwise, the step two of reapplication is returned. Firstly, the data exchange platform judges the effectiveness of the interface service by using a public key provided by a data service visitor, and if the effectiveness is ensured, a private key corresponding to the public key is generated for the service visit; secondly, under the condition that the interface service is effective, further judging whether the time stamp of the data access request and the time difference are lower than a threshold value, such as 3 minutes, if the time difference exceeds a preset criterion, determining the data access request as a hotlink and rejecting the access; furthermore, the data access platform continuously detects whether the frequency and the times of the access of the interface service are lower than an expected threshold value, if so, the access is stopped, otherwise, the access is continued; and finally, detecting whether the IP address of the interface service access source is safe, if not, denying access, and if so, completely finishing the whole test process, determining that the access is effective, and performing the next action on the basis.
In step four: the administrator grants the related interface authority of the data service accessor through the application of the related business interface service, and then the data service provider provides corresponding information for the successfully accessed data service accessor. The data service provider firstly establishes connection with the data exchange platform, then caches the acquired data in the redis storage system, and then signs the acquired data by using a private key provided by the data exchange platform and returns the signed data to the data service visitor.
Referring now to fig. 2 and 3, fig. 2 is a block diagram of a data service access flow according to an embodiment of the present invention. Fig. 3 is a data caching process according to an embodiment of the present invention. The specific process is that a data service visitor needs to select a data service interface required by self business on a data exchange platform and enter an approval link after the data service visitor confirms the data service interface. The service provider needs to configure a data interface access public key required by data access on the data exchange platform, and after the administrator passes the approval, the data service provider needs to register service on the data exchange platform for the application program. The data service accessor accesses the relevant service interface by using the certificate (APPID, APPSECRET), signature, time stamp and the parameter necessary for accessing the interface service provided by the exchange platform. And the data exchange platform judges whether the provided certificate is the certificate issued by the platform after receiving the request, if the certificate is matched with the certificate, the next step is carried out, and if the certificate is not matched with the certificate, the access is denied. Further, the data exchange platform verifies whether the signature of the request is valid by using the public key provided by the data service access provider, and if the signature is valid, the next step is carried out. And further, the data exchange platform judges the time stamp of the data access request, judges whether the time difference is lower than a threshold value, if so, the data exchange platform determines the data access request as a hotlink and refuses access, otherwise, the data exchange platform performs the next step. Furthermore, the data exchange platform detects whether the frequency and the times of accessing the data service by the data accessor are lower than expected threshold values, if so, the next step is carried out for effective access. And finally, the data exchange platform detects whether the data request source is consistent with the source of the preset configuration or not, if the data request source is effective, the next step is carried out, and meanwhile, the data exchange platform detects whether the state of the data service is normal or not, and if the data service is normal, the next step is carried out.
After successful verification, the data exchange platform next creates a connection with the data service provider. After the connection is completed, the data service provider provides required parameters, extracts data of the data service provider, caches the acquired data in the redis, and signs the data by using a private key of the platform to access the data to provide the data service visitor.
In the whole access application process, the data service provider additionally records the record, the processing log and the processing speed of the data service access, updates the data services and makes a related statistical report. By analyzing the business data related to the report, the early warning judgment can be carried out on the data service access condition. Upon an access exception, the data service provider may refuse to provide the data, even if the data exchange platform is successfully authenticated.
