HTTP request methods

Implement the HTTP request on the following URI, where supermapiserver is the server name, with rjson being the output format.

http://supermapiserver:8090/iserver/services/data-jingjin/rest/data/feature/0-8-2/metadata.xml

GET request

The metadata resource is used to represent the metadata for geographical features. It includes the creator, date created, last editor, last edit time, etc of the geographic data.

Response structure

Execute a GET request on the metadata resource. The representation structure for the returned resource is like this:

Field Type Description
createTime long Create time.
createUser String[] The creator (if the current service is authorized to be accessed anonymously, the creator cannot be seen.)
lastEditTime long The last edit time.
lastEditUser String[] The last editor (if the current service is authorized to be accessed anonymously, the last editor cannot be seen.)

Response example

Execute a GET request on the metatdata resource:

http://supermapiserver:8090/iserver/services/data-jingjin/rest/data/feature/0-8-2/metadata.rjson

The result returned is as follows:

{

    "createTime": 1436945830474,

    "createUser": "admin",

    "lastEditTime": 1436945830474,

    "lastEditUser": "admin"

}

HEAD request

Asks for the response identical to the one that would correspond to a GET request, but without the response body. This is useful for retrieving meta-information written in response headers, without having to transport the entire content. The meta-information includes the media-type, content-encoding, transfer-encoding, content-length, etc.

HEAD request can be used to check if the metadata resource exists, or if the metadata resource can be accessed by clients. It can also determine if the metadata resource supports an output format <format> if performed on a URI with .<format> included.
