The approval instruction is an instruction related to an approval result, and may be an instruction for ending approval data, where the approval instruction carries an approval result, and the approval result is used to determine a state of a download interface corresponding to the second network environment, and includes but is not limited to approval passing and approval failing. And the different approval results correspond to different download interface states, for example, if the approval result is approval pass, the download interface state of the second network environment is an open state, and if the approval result is approval fail, the download interface state of the second network environment is a closed state.

Furthermore, after the approval data corresponding to the approval data identification is sent to the approval terminal for approval by the approval staff, the approval staff can send an approval instruction through the approval terminal after approval is finished, and the approval result is carried to the approval instruction and then sent to the server through network communication.

And 308, determining the interface state corresponding to the download interface corresponding to the second network environment according to the approval result.

And the pending approval notification is a message used for notifying the approval user of approval, and includes the uploading time, the uploading user, the data type and other contents corresponding to the pending data. However, the pending approval notification is only a message for notifying the approval user of approval, and is not actual data that requires approval.

Further, the server determines the corresponding approval user terminal according to the pending user identification in the pending approval request of the transmitted data, and then sends a pending approval notice to the approval user terminal to inform the approval user terminal to approve the uploaded data. Finally, the approval user terminal may display the pending approval notification on the terminal.

Or detecting whether the user identity information corresponding to the uploading user identifier has an identity association relationship with the preset user identity information, and determining that the user identity information has the uploading authority when the identity association relationship exists. The identity association relationship means that a certain relationship exists between identity information, and may be an authorization relationship.

Further, while checking whether the user identity information corresponding to the uploading user identifier has the uploading authority, it is necessary to check whether the data to be transmitted carried by the uploading request of the data to be transmitted meets preset data conditions, specifically, it may be checked whether the data format, the data name and the data size corresponding to the data to be transmitted meet preset data conditions, where the preset data conditions include, but are not limited to, preset format conditions, preset name conditions and preset data size conditions, it is checked whether the data format corresponding to the data to be transmitted meets preset format conditions, it is checked whether the data name corresponding to the data to be transmitted meets preset name conditions, it is checked whether the data size corresponding to the data to be transmitted meets preset data size conditions, when the data format corresponding to the data to be transmitted meets preset format conditions, the data name corresponding to the data to be transmitted meets preset name conditions, and when the data size corresponding to the data to be transmitted meets the preset data size condition, determining that the data to be transmitted carried by the data uploading request to be transmitted meets the preset data condition.

In a specific application scenario, as shown in fig. 7A, fig. 7A is a schematic diagram illustrating a principle of a data transmission method between multiple network environments in one embodiment, where the apparatus shown in fig. 7A may be applied to the data transmission method between the multiple network environments, and may be a server with multiple network cards, and each network card is configured with a network address of a different network environment, which is specifically described in detail with reference to the following steps:

1. there is a physical application server for placing the device. The device provides two access addresses (which can be domain names or IP) for the network environment A and the network environment B, and the domain names or the IP are only subordinate to one network environment, namely the domain names or the IP in the other network environment cannot be accessed in one network environment.

2. On the physical application server, the device is deployed.

3. A reverse proxy such as Nginx, Apache, etc. is installed on the physical application server (the reverse proxy is one of a plurality of open source reverse proxies that are popular in the market, and can only play the same role). The network card of network environment a binds to an address (which may be IP or domain name) specific to network environment a, and the network card of network environment B binds to an address (which may be IP or domain name) specific to network environment B. Wherein a reverse proxy may be understood simply as being used for an external service and an internal pointing device, in this embodiment, the reverse proxy is primarily intended to provide an external portal service to a different network environment.

4. From the topology of the network environment and the external services, the network environment a and the network environment B are completely isolated, because they use different network cards and network ports, and bound with different addresses (which can be IP or domain names), the physical application server provides services for the two network environments at the same time, and ensures that the two services are not intercommunicated, because the network cable connected with the network card of the network environment a is not connected to any terminal of the network environment B, it is impossible to access any terminal of the network environment B, only in the case of connection, the terminals under the network can access each other, and through different configurations in the reverse proxy, the domain names of the two network environments can be routed to the two network cards.

5. From the perspective of the physical application server, the network environment a and the network environment B share the same front end, back end and file storage, and when sharing or downloading is required, they actually share the same disk under the same physical server, and when necessary, the device can realize sharing and isolation of files together.

It should be understood that, although the steps in the above-described flowcharts are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least a portion of the steps in the above-described flowcharts may include multiple sub-steps or multiple stages, which are not necessarily performed at the same time, but may be performed at different times, and the order of performing the sub-steps or the stages is not necessarily sequential, but may be performed alternately or alternatingly with other steps or at least a portion of the sub-steps or stages of other steps.
