Detailed Description
The invention provides a domain name dynamic switching method of an intelligent terminal application program and an intelligent terminal, and the invention is further described in detail below in order to make the purpose, technical scheme and effect of the invention clearer and clearer. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a domain name dynamic switching method for an intelligent terminal application according to a preferred embodiment of the present invention, as shown in the figure, the method includes the following steps:
s1, defining a default domain name in a hard coding mode in an application program;
s2, storing the domain name file in the cloud server and providing a download address to the application program;
s3, when the application program is started for the first time, reading a default domain name, downloading a domain name file according to the download address, analyzing the domain name file, acquiring a new domain name in the domain name file, and storing the new domain name;
and S4, when the application program is restarted, replacing the current domain name with the stored new domain name.
The invention uses the default domain name when the domain name is started for the first time and uses the downloaded new domain name when the domain name is restarted, so that any new domain name can be still used after the application program is released, thereby realizing the dynamic switching of the domain name.
Specifically, in step S1, the present invention first defines a default domain name in a hard-coded manner in the application program, and the default domain name is used when the application program is started for the first time. Further, the default domain name may also be used as a backup for failure exception, that is, in the subsequent step, if downloading of a new domain name fails, the default domain name is used as a backup.
That is, the default domain name command value cannot be changed and erased. The function is as follows: firstly, the method is used when the application program is started for the first time; and secondly, the dynamic domain name is used as a standby domain name when the dynamic domain name is not pulled.
In step S2, the domain name file is stored in the cloud server, and the download address is provided to the application program.
The cloud server may be a third-party cloud server, that is, a server not corresponding to the domain name related to the present invention. Therefore, the address of the third-party cloud server cannot be changed, and the application program can conveniently acquire the latest domain name file at any time.
For example, a hostname file (domain name file) is stored in the cloud server, the domain name to be switched is written into the file, and a download address is provided for the application program
The domain name file is a dynamic domain name configuration basis, and a domain name (namely a new domain name) to be switched is written in the domain name file. Preferably, the domain name file is encrypted, so that the security of the domain name file can be ensured. That is, when writing a domain name, the domain name should be written in a ciphertext to ensure security. The encryption method can be any mature symmetric encryption algorithm. And after the writing is finished, the external access link of the domain name file is exposed, so that the application program can access and download.
In step S3, when the application is first started, the default domain name is read. And simultaneously downloading the domain name file according to the download address, then analyzing the domain name file, acquiring a new domain name in the domain name file and storing the new domain name.
Specifically, the default domain name is used after being read, and thereafter, a server-related request of the entire application is initiated on the basis of the default domain name.
After the cloud server is accessed, the domain name file is downloaded, and if the domain name file is downloaded successfully, the domain name file is decrypted, for example, by using a symmetric algorithm, a new domain name in the domain name file is obtained, and the obtained new domain name is stored. If the download fails, the existing default domain name is maintained without any change.
When the new domain name is saved, the new domain name is preferably saved persistently, for example, the new domain name is saved in a storage space of an application program by a shell-adding packaging method, so that the new domain name is ensured not to be lost. In particular, for relative security purposes, archival storage may be used, as well as storage in the sqlite database.
In step S4, when the application is restarted, the current domain name (the current domain name is the default domain name) is replaced with the saved new domain name.
Specifically, the step S4 specifically includes:
s41, when the application program is restarted, detecting whether a usable new domain name is stored locally, if so, entering a step S42, and if not, ending the process;
and S42, reading the new domain name and replacing the current domain name with the new domain name.
In step S41, when the application is restarted, it is detected whether a usable new domain name is locally stored, and since the previously downloaded domain name file is not necessarily downloaded successfully or usable, it is necessary to detect whether a usable new domain name is locally stored, and if so, the process proceeds to step S42, and if not, the process may be terminated as it is.
In the step S42, the new domain name is read, and then the current domain name, i.e., the default domain name, is replaced with the new domain name.
And after the current domain name is replaced, sending a notice to the whole application program, releasing all data depending on the current domain name, and requesting the data again on the basis of the new domain name.
That is, after replacing the current domain name, the related request of the service end of the whole application program is initiated based on the new domain name, so as to achieve the purpose of switching the domain name. The replacement domain name should occur before all server requests and the execution priority of the replacement domain name should be set to a high level.
Further, the step S4 is followed by:
and S5, continuously downloading the new domain name file to the cloud server, analyzing the new domain name file to obtain a new domain name therein, and replacing the current domain name with the new domain name.
After the domain name is replaced, the request for downloading the hostname file of the cloud server is also continuously requested. And if the new domain name file exists, downloading the new domain name file, and analyzing to obtain the new domain name. The domain name file of this step is different from the domain name file in step S2, and is the latest domain name file.
That is to say, the domain name file stored in the cloud server can be updated at any time, so that the application program downloads the latest domain name file to the cloud in the running process, and the latest domain name file is acquired.
After downloading the new domain name file, the new domain name file is decrypted, and then the new domain name is obtained, and the current domain name can be updated and replaced by adopting the similar method.
Specifically, the step S5 specifically includes:
s51, continuously downloading a new domain name file to the cloud server, analyzing the new domain name file to obtain a new domain name therein, and storing the new domain name;
and S52, when the application program is reactivated, matching the current domain name with the locally stored new domain name, if the current domain name is consistent with the locally stored new domain name, ending the process, and if the current domain name is inconsistent with the locally stored new domain name, replacing the current domain name with the new domain name.
In step S51, a request is made to the cloud server to download a new domain name file, and the new domain name file is decrypted to obtain a new domain name therein, and then persistent storage is performed, for example, archival storage may be adopted, and storage may also be performed in the sqlite database.
In step S52, when the application is reactivated, the stored new domain name is matched with the current domain name, and if the stored new domain name and the current domain name are consistent, the new domain name does not need to be updated, and if the stored new domain name and the current domain name are not consistent, the current domain name is replaced with the new domain name (the current domain name is the new domain name used in step S4).
And after the current domain name is replaced, sending a notice to the whole application program, releasing all data depending on the original domain name, and requesting data again on the basis of the newly replaced domain name.
The reactivation of the application in step S52 refers to: when the application program is suspended, the intelligent terminal returns to a desktop or other applications, and then the application program is reactivated; but may also refer to restarting the application.
In addition, it should be noted that, in the present invention, since the domain name file is updated in the cloud server so that the application program can obtain the latest domain name, the present invention preferably identifies the downloaded new domain name, which is convenient for subsequent comparison and matching, thereby using the latest domain name. For example, a version identifier or a time identifier may be added, for example, the first new domain name is labeled V1.0, the second new domain name is labeled V1.1, the third new domain name is labeled V1.2, and so on; or the first time new domain name is labeled V2017.9.26, the second time new domain name is labeled V2017.10.12, the third time new domain name is labeled V2017.10.22, and so on. The new domain names can be stored in the storage space of the application program persistently at the same time, after the new domain names are downloaded, the currently used domain names are matched with the downloaded new domain names, and whether the currently used domain names are the new domain names or not is judged.
To avoid performing the process of comparing matches each time an application is reactivated, a match may be made when a download to a new domain name is detected and the application is reactivated, thereby improving efficiency.
The present invention also provides an intelligent terminal, which includes:
a processor adapted to implement the instructions, an
A storage device adapted to store a plurality of instructions, the instructions adapted to be loaded and executed by a processor to:

and when the application program is restarted, replacing the current domain name by the stored new domain name.
The processor may be a general purpose processor, a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA), a single chip, an arm (acorn RISC machine) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination of these components. Also, the processor may be any conventional processor, microprocessor, or state machine. A processor may also be implemented as a combination of computing devices, e.g., a combination of a DSP and a microprocessor, a plurality of microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration.
The storage device, which is a non-volatile computer-readable storage medium, may be used to store a non-volatile software program, a non-volatile computer-executable program, and a module, such as a program instruction corresponding to the domain name dynamic switching method in the embodiment of the present invention.
