Problems solved by technology

[0002] In the current B / S interaction technology, if the front-end JavaScript interacts with local Java applications, it must be realized through middleware. The problem brought about by this is that when the system cannot be directly deployed on the network, each client needs a supporting Middleware not only has high economic costs, but also increases the development complexity accordingly, wasting a lot of manpower and material resources

Embodiment Construction

[0031] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0032] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0033] Such as figure 1 As shown, the steps involved in the present invention are described, specifically as follows:

[0034] S1. Java-based SP service registration is performed when the custom browser framework is started, including front-end JavaScript-receiving interface services, message encapsulation services, and message parsing services based on JSON-based front-end and back-end interaction proprietary protocols;

[0035] S2. The front-end JavaScript encapsulates the command and parameters used for the request into a message body according to the front-end interaction proprietary protocol based on the JSON specification, and sends the encapsulated message body to the back-end by...

Abstract

The present invention provides a kind of interaction method and device of front-end JavaScript and local Java application, comprise the following steps: S1, carry out the SPI service registration based on Java when the self-defined browser framework starts, including front-end and back-end interaction proprietary protocol based on JSON specification Interface service, message encapsulation service and message analysis service for receiving front-end JavaScript requests. Beneficial effects of the present invention: a method and device for interaction between front-end JavaScript and local Java applications effectively solves the problem that middleware is needed when front-end JavaScript interacts with local Java applications, and can greatly reduce system construction costs when deployed on a single machine. The development device provided by the invention reduces the development difficulty and improves the development efficiency.

Description

technical field [0001] The invention belongs to the technical field of software development, and in particular relates to an interaction method and device for front-end JavaScript and local Java applications. Background technique [0002] In the current B / S interaction technology, if the front-end JavaScript interacts with local Java applications, it must be realized through middleware. The problem brought about by this is that when the system cannot be directly deployed on the network, each client needs a supporting Middleware not only has high economic costs, but also increases the development complexity accordingly, wasting a lot of manpower and material resources. Contents of the invention [0003] In view of this, the present invention aims to propose a method and device for interacting with front-end JavaScript and local Java applications, which realizes direct communication between the custom browser framework and local Java applications. In a special working envir...
