Description
Technical Field
The present disclosure relates to the field of information processing technologies, and in particular, to a method and an apparatus for redirecting and transmitting a clipboard, a storage medium, and an electronic device.
Background
In the cloud era, more and more desktops and applications run in the cloud environment, and the local PC is connected to the cloud through the remote desktop to enjoy the high-speed and safe running environment of the cloud environment. There are numerous ways of sharing data between remote environments and the local, with the transfer of data through a clipboard being one of the most convenient ways. The method comprises the steps that on a local PC, copying operation is executed, a clipboard format list is sent to a far end through a connecting channel of a local desktop and a far-end desktop, after the far end receives the clipboard format list, the clipboard format list is injected into a remote system clipboard, and at the moment, the system clipboard can be triggered to complete a clipboard data request through pasting operation in a remote desktop environment.
In the related art, the content of the paste data is very large, for example, a file is as large as several G to several tens G. At this time, the remote desktop triggering and pasting, such as the file manager, does not issue a request of several G to several tens G of file contents at a time, but requests the file contents uniformly and orderly through the system clipboard and a package-by-package sub-package.
After the pasting operation is executed on the remote desktop, the file manager on the remote desktop requests file contents with a certain size, such as 4K, through a system clipboard, sends the request command to the local through a connecting channel of the local desktop and the remote desktop, collects the file contents of 4K after the command is received locally, and returns the content data of the 4K file to a data request end of the remote desktop through the connecting channel of the local desktop and the remote desktop. After receiving the 4K file content, actively triggering a second 4K file content request. When the file content is large, the subsequent process is repeatedly operated according to the process, and the same process is repeatedly repeated back and forth until the file content request is processed.
Therefore, there is a need to provide a new technical solution to improve one or more of the problems in the above solutions. For example: the network requests and response times are excessive, and the sending and requesting of bidirectional data need to be completed for 2n times; for each packet of response data, extra packet header information is required to be added to record the uniqueness of the data, such as data format marks, data size and the like, and corresponding unpacking processing matters need to be carried out at a receiving end; all requests and responses sent are completed in the only connection channel between the local desktop and the remote desktop.
