示例1: GetAll
// GetAll dumps the entire database of nodes, including cached
// ones. If the form value `since` is supplied with a valid RFC3339
// timestamp, only nodes updated or cached more recently than that
// will be dumped. If 'geojson' is present, then the "data" field
// contains the dump in GeoJSON compliant form.
func (*Api) GetAll(ctx *jas.Context) {
// We must invoke ParseForm() so that we can access ctx.Form.
ctx.ParseForm()
// In order to access this at the end, we need to declare nodes
// here, so the results from the dump don't go out of scope.
var nodes []*Node
var err error
// If the form value "since" was supplied, we will be doing a dump
// based on update/retrieve time.
if tstring := ctx.FormValue("since"); len(tstring) > 0 {
var t time.Time
t, err = time.Parse(time.RFC3339, tstring)
if err != nil {
ctx.Data = err.Error()
ctx.Error = jas.NewRequestError("invalidTime")
return
}
// Now, perform the time-based dump. Errors will be handled
// outside the if block.
nodes, err = Db.DumpChanges(t)
} else {
// If there was no "since," provide a simple full-database
// dump.
nodes, err = Db.DumpNodes()
}
// Handle any database errors here.
if err != nil {
ctx.Error = jas.NewInternalError(err)
l.Err(err)
return
}
// If the form value 'geojson' is included, dump in GeoJSON
// form. Otherwise, just dump with normal marhshalling.
