Synchronous interface to asynchronous processes
Examples of methods, apparatus, and computer program products are disclosed for facilitating access to one or more services in a network environment. At a host, a request is received from a client machine in communication with the host over a network. An asynchronous service description file indicates one or more asynchronous communication techniques configured to be performed to access or communicate with a service over the network. The asynchronous service description file is a conversion of a synchronous service description file indicating one or more synchronous communication techniques for accessing or communicating with a synchronous service. The asynchronous service description file is provided to the client machine.
1. A system comprising:
one or more processors operable to cause:
processing a request from a client machine in communication with a host over a network;
obtaining first data indicating one or more asynchronous communication techniques configured to be performed by a machine to access or communicate with a service over the network, the first data being a conversion of second data indicating one or more synchronous communication techniques for accessing or communicating with a synchronous service; and
providing, to the client machine, the first data.
2. The system of claim 1 , wherein the first data and the second data are service description files in web service description language (WSDL) format.
3. The system of claim 1 , the one or more processors further operable to cause:
obtaining permission information indicating a permission of the client machine to access one or more services.
4. The system of claim 3 , wherein obtaining the permission information includes:
performing one or more security management operations in association with the client machine or with a user of the client machine.
5. The system of claim 4 , wherein the security management operations include one or more of: authentication, authorization, security policy enforcement, decryption, and validation of a digital signature.
6. The system of claim 3 , wherein obtaining the permission information includes:
retrieving the permission information from a policy repository.
7. The system of claim 1 , the one or more processors further operable to cause:
providing, at the host, one or more interfaces for communications between the client machine and the synchronous service over the network, the one or more interfaces permitting:
synchronous communications with the synchronous service in accordance with the second data, and asynchronous communications with the client machine in accordance with the first data.
8. The system of claim 1 , the one or more processors further operable to cause:
processing a message from the client machine at an asynchronous interface;
processing the message at the host; and
providing the processed message to the synchronous service at a synchronous interface.
9. The system of claim 8 , wherein providing the processed message to the synchronous service includes:
sending the processed message in response to polling by the synchronous service.
10. The system of claim 1 , the one or more processors further operable to cause:
processing a message from the synchronous service at a synchronous interface;
processing the message at the host; and
providing the processed message to the client machine at an asynchronous interface.
11. The system of claim 1 , wherein obtaining the first data includes:
converting the second data to the first data.
12. The system of claim 1 , wherein obtaining the first data includes:
retrieving the first data from a storage medium accessible at the host.
13. A method comprising:
receiving, at a host, a request from a client machine in communication with the host over a network;
obtaining, at the host, first data indicating one or more asynchronous communication techniques configured to be performed by a machine to access or communicate with a service over the network, the first data being a conversion of second data indicating one or more synchronous communication techniques for accessing or communicating with a synchronous service; and
providing, to the client machine, the first data.
14. The method of claim 13 , wherein the first data and the second data are service description files in web service description language (WSDL) format.
15. The method of claim 13 , the method further comprising:
obtaining permission information indicating a permission of the client machine to access one or more services.
16. The method of claim 15 , wherein obtaining the permission information includes:
performing one or more security management operations in association with the client machine or with a user of the client machine.
17. A computer program product comprising computer-readable program code to be executed by one or more processors when retrieved from a non-transitory computer-readable medium, the program code including instructions configured to cause:
processing a request from a client machine in communication with a host over a network;
obtaining first data indicating one or more asynchronous communication techniques configured to be performed by a machine to access or communicate with a service over the network, the first data being a conversion of second data indicating one or more synchronous communication techniques for accessing or communicating with a synchronous service; and
providing, to the client machine, the first data.
18. The computer program product of claim 17 , wherein the first data and the second data are service description files in web service description language (WSDL) format.
19. The computer program product of claim 17 , the program code including further instructions configured to cause:
obtaining permission information indicating a permission of the client machine to access one or more services.
20. The computer program product of claim 19 , wherein obtaining the permission information includes:
performing one or more security management operations in association with the client machine or with a user of the client machine.
