Cache Management Interface

Purge Cache/Query Purge Status Purge/GetPurgedStatus
You can clear cache by URL purge or directory purge. URL refresh is to refresh cache with a file or a resource as the unit. The directory refresh is to clean the cache of all files under the directory in the unit of directory.
cli := client.GetDefaultClient()
//Delete
purgedId, err := cli.Purge([]api.PurgeTask{
{
Url: "http://my.domain.com/path/to/purge/2.data",
},
{
Url: "http://my.domain.com/path/to/purege/html/",
Type: "directory",
},
})
fmt.Printf("purgedId:%+v\n", purgedId)
fmt.Printf("err:%+v\n", err)
//Query the removal status according to task ID.
purgedStatus, err := cli.GetPurgedStatus(&api.CStatusQueryData{
Id: string(purgedId),
})
fmt.Printf("purgedStatus:%+v\n", purgedStatus)
fmt.Printf("err:%+v\n", err) In the example, two types of resource are removed, among which the first one is to remove a file, and the second one is to remove all files under a certain directory. Query the task progress according to the task id returned by purge. api.CStatusQueryData is a relatively complex structure. You can query based on different conditions. For details, please see the definition.
Prefetch/GetPrefetchStatus
URL prefetch is the resource warm-up with file as a unit.
cli := client.GetDefaultClient()
prefetchId, err := cli.Prefetch([]api.PrefetchTask{
{
Url: "http://my.domain.com/path/to/purge/1.data",
},
})
fmt.Printf("prefetchId:%+v\n", prefetchId)
fmt.Printf("err:%+v\n", err)
prefetchStatus, err := cli.GetPrefetchStatus(&api.CStatusQueryData{
Id: string(prefetchId),
})
fmt.Printf("prefetchStatus:%+v\n", prefetchStatus)
fmt.Printf("err:%+v\n", err) Query Purging/Prefetching Quota GetQuota
cli := client.GetDefaultClient()
quotaDetail, err := cli.GetQuota()
fmt.Printf("quotaDetail:%+v\n", quotaDetail)
fmt.Printf("err:%+v\n", err) quotaDetail is an object in api.QuotaDetail type, and the details are as follows:
| Field | Type | Description |
|---|---|---|
| DirRemain | int | Balance of the directory purge quota in the day. |
| UrlRemain | int | Refresh (including warm-up) URL residual quota in the current day. |
| DirQuota | int | Purge directory total quota |
| UrlQuota | int | Refresh (including prefetch) URL total quota |
