Method and device for handling multi-tenant request
Implementations of the present specification provide a method and device for handling a multi-tenant request. A request to access an application from a user device is received, wherein the request includes a user identifier and request data. Tenant information corresponding to the user identifier is determined based on a mapping relationship between the user device and a tenant. Type information of the application is determined based on the request data. A first identifier of the application is extracted from the request data based on the type information of the application. The first identifier is modified to a second identifier based on the tenant information. A new request is determined based on the second identifier. The new request is sent to the application.
1. A computer-implemented method, comprising:
receiving a request to access an application from a user device, wherein the request comprises a user identifier and request data, wherein the application is hosted by a server, and wherein the user identifier is associated with a user of the user device;

determining type information of the application based on the request data;
extracting a first identifier of the application from the request data based on the type information of the application;
appending the tenant information to the first identifier of the application to obtain a second identifier;
determining a new request based on the second identifier;
sending the new request to the application;
receiving a response message for the new request, wherein the response message comprises the second identifier;
removing the tenant information from the second identifier to obtain the first identifier of the application;
determining a new response message based on the first identifier; and
returning the new response message to the user device.
2. The computer-implemented method of claim 1 , wherein extracting the first identifier of the application from the request data based on the type information comprises:
determining an identification field corresponding to the type information of the application based on a mapping relationship between an application type and the identification field;
extracting a field value of the identification field from the request data based on the identification field; and
using the field value as the first identifier.
3. The computer-implemented method of claim 2 , wherein the mapping relationship between the application type and the identification field is stored in a two-dimensional relationship table or stored in a storage system of a key value (KV) structure.
4. The computer-implemented method of claim 1 , wherein the extracting a first identifier of the application from the request data based on the type information comprises:
determining an extraction method of a field value of an identification field corresponding to the type information of the application based on a mapping relationship between an application type and the extraction method of the field value of the identification field;
extracting the field value of the identification field from the request data based on the extraction method; and
using the field value as the first identifier.
5. The computer-implemented method of claim 4 , wherein the mapping relationship between the application type and the extraction method of the field value of the identification field is stored in a two-dimensional relationship table or stored in a storage system of a key value (KV) structure.
6. A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:
receiving a request to access an application from a user device, wherein the request comprises a user identifier and request data, wherein the application is hosted by a server, and wherein the user identifier is associated with a user of the user device;
determining tenant information corresponding to the user identifier based on a mapping relationship between the user and a tenant;
determining type information of the application based on the request data;
extracting a first identifier of the application from the request data based on the type information of the application;
appending the tenant information to the first identifier of the application to obtain a second identifier;
determining a new request based on the second identifier;
sending the new request to the application;
receiving a response message for the new request, wherein the response message comprises the second identifier;
removing the tenant information from the second identifier to obtain the first identifier of the application;
determining a new response message based on the first identifier; and
returning the new response message to the user device.
7. The non-transitory, computer-readable medium of claim 6 , wherein extracting the first identifier of the application from the request data based on the type information comprises:
determining an identification field corresponding to the type information of the application based on a mapping relationship between an application type and the identification field;
extracting a field value of the identification field from the request data based on the identification field; and
using the field value as the first identifier.
8. The non-transitory, computer-readable medium of claim 7 , wherein the mapping relationship between the application type and the identification field is stored in a two-dimensional relationship table or stored in a storage system of a key value (KV) structure.
9. The non-transitory, computer-readable medium of claim 6 , wherein the extracting a first identifier of the application from the request data based on the type information comprises:
determining an extraction method of a field value of an identification field corresponding to the type information of the application based on a mapping relationship between an application type and the extraction method of the field value of the identification field;
extracting the field value of the identification field from the request data based on the extraction method; and
using the field value as the first identifier.
10. The non-transitory, computer-readable medium of claim 9 , wherein the mapping relationship between the application type and the extraction method of the field value of the identification field is stored in a two-dimensional relationship table or stored in a storage system of a key value (KV) structure.
11. A computer-implemented system, comprising:
one or more computers; and
one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform operations comprising:
receiving a request to access an application from a user device, wherein the request comprises a user identifier and request data, wherein the application is hosted by a server, and wherein the user identifier is associated with a user of the user device;
determining tenant information corresponding to the user identifier based on a mapping relationship between the user and a tenant;
determining type information of the application based on the request data;
extracting a first identifier of the application from the request data based on the type information of the application;
appending the tenant information to the first identifier of the application to obtain a second identifier;
determining a new request based on the second identifier;
sending the new request to the application;
receiving a response message for the new request, wherein the response message comprises the second identifier;
removing the tenant information from the second identifier to obtain the first identifier of the application;
determining a new response message based on the first identifier; and
returning the new response message to the user device.
