File acquisition method and device

Abstract

The invention relates to the field of finance science and technology, and discloses a file obtaining method and device. A native application receives a file obtaining request sent by a web application; if the native application determines that the terminal starts the HTTP service, the native application loads a local file to a project folder; and the native application generates a uniform resource locator url for obtaining the local file based on the storage path of the local file corresponding to the project folder, and sends the url to the web application. According to the mode, under the scene that the terminal starts the HTTP service, the file desired by the web application is processed into the url form for obtaining the file, so that the web application can obtain the desired file from the terminal in a mode of sending the HTTP request, the effect of light weight in the file obtaining process is achieved, and the file obtaining efficiency is improved. And the web application does not need to be embedded into the native application, so that the method and the device are suitable for web applications deployed on line.

Description

technical field [0001] The embodiments of the present application relate to the field of financial technology (Fintech), and in particular, to a method and apparatus for acquiring a file. Background technique [0002] With the development of computer technology, more and more technologies (such as big data, cloud computing or blockchain) are applied in the financial field, and the traditional financial industry is gradually transforming into financial technology. For example, with the continuous expansion of banking business, the bank designs a native application that is matched with enterprise WeChat. Based on this native application, multiple customer service personnel of the bank can use the same enterprise WeChat account and according to the web browser they open in their browsers. Application interface to provide business services to customers. [0003] For the business service process described above, due to sandbox restrictions and browser security restrictions, the ...

Problems solved by technology

[0006] Disadvantage 1: This process is prone to time-consuming base64 encoding phase, time-consuming base64 file transmission phase, and time-consuming browser parsing base64 file to obtain the image phase; and, because the average size of the base64-encoded file is compared to the source file It will increase by about 30%. Therefore, if there are 10 pictures in the 20 chat messages to be pulled, and each picture itself is 2M, and the encoded base64 string may become 3M, then the web application is requesting the scene. When chatting messages, 30M information will need to be transmitted, and it will take up memory

In addition, there is also the disadvantage of poor caching. Even if the same record is pulled every time, it is necessary to repeatedly generate, transfer, and read the base64 string

[0007] Disadvantage 2: Deploying web applications in native applications will lead to a higher degree of coupling between web applications and native applications, which is not conducive to the development of native applications; in addition, this method is not suitable for deploying online web applications
