and the multi-modal service providing module is configured to determine the type of the service according to the downstream service basic data provided by the routing module, establish a communication channel with the corresponding service and return a processing result of the service to the terminal.

The attributes of the configured route in the gateway route configuration module comprise an upstream service route, a downstream service route, service aggregation, configured service authentication, current limiting configuration, cache configuration, service quality and fusing, and header information forwarding.

Compared with the prior art, the invention has the following advantages and beneficial effects:

(1) the invention is independently deployed on the network, builds a communication pipeline between the application and the multi-mode Service, automatically adapts various modal services (HTTP/HTTPS Service, web Service, webscolet Service, RPC Service, message queue Service, Internet of things Service and the like) for the application, provides an interface or abstract class for expanding the user-defined Service, and can flexibly realize the interface or inherit the abstract class to realize the quick butt joint of the user-defined Service.

(2) The invention avoids the workload of developing and adapting the multi-mode service for each application, realizes the self-adaptive switching by connecting the multi-mode gateway, realizes that the client application can communicate with the multi-mode service only through HTTP, and greatly reduces the development and deployment cost.

Detailed Description

The present invention will be described in further detail with reference to examples, but the embodiments of the present invention are not limited thereto.

Example (b):

with reference to fig. 1, a system for configuring an adaptive transit gateway for multimodal services includes a multimodal service gateway and a multimodal service gateway background management, where the multimodal service gateway includes a current limiting module, an authentication module, a routing module, a service quality and fusing module, and a multimodal service providing module; the multimodal service gateway background management comprises a basic management module and a gateway routing configuration module. Wherein:

the basic management module comprises a user management module, an authority management module, an access amount counting module and a log query module, provides basic user and authority management, and provides log query and access amount counting for terminal access;

a gateway route configuration module: providing a service for configuring a route, the route comprising the following attributes: the multi-mode service gateway comprises an upstream service route, a downstream service route, service aggregation, configuration service authentication, current limiting configuration, cache configuration, service quality and fusing, header information forwarding and the like, if the multi-mode service gateway fails to provide certain reset, a service component can be defined by a user and is led in through the module.

A current limiting module: aiming at the configuration of basic data in a gateway routing configuration module, whether the routing starts the current limiting or not is obtained, if the current limiting is not needed, the verification is skipped, if the current limiting is needed, the current limiting is carried out according to corresponding strategies (the client can retry after a plurality of seconds, the maximum request number allowed in a statistical time period, an access white list and the like), the current limiting of the request is realized, and the crash of a downstream server due to access overload is prevented;

an authentication module: the authentication of the user request of the client is realized, and the service provided by the multi-modal service gateway is not allowed to be used when the user authentication is not carried out; the authentication module supports the authentication modes of JWT and Identity Server;
