I am working on a new hobby project RESTifying the ZFS APIs, Earlier I was using play framework for my REST projects, now started using SpringBoot
While RESTifying the ZFS API one of the API formats is like
@GetMapping(path = {"/", "/{poolname}", "/{poolname}/{volumename}"}, produces = "application/json")/ will give all the pool name and volumes, /poolname will give all the pool name and volumes of that particular pool, /poolname/”poolname/volumename” should give the pool and the volume.
The volume name is in the format {poolname}/{volumename}, so I want to provide the slash with URL encoded but given restful method below gives HTTP Status 400 – Bad Request
GET http://zfsappliance:8080/zfs/sql-pool/sql-pool%2Fdisk1
Accept: application/json
</head>
<body><h1>HTTP Status 400 – Bad Request</h1></body>
</html>Without the %2F everything works fine.
Resolution
System.setProperty("org.apache.tomcat.util.buf.UDecoder.ALLOW_ENCODED_SLASH", "true");
@Override
public void configurePathMatch(PathMatchConfigurer configurer) {
UrlPathHelper urlPathHelper = new UrlPathHelper();
urlPathHelper.setUrlDecode(false);
configurer.setUrlPathHelper(urlPathHelper);
}By adding the above method in the main function, I am able to get the response correctly.
GET http://10.10.109.81:8080/zfs/sql-pool/sql-pool%2Fdisk1
Accept: application/json[
