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.
	if _, ok := ctx.Form["geojson"]; ok {
		ctx.Data = FeatureCollectionNodes(nodes)
	} else {
		mappedNodes, err := Db.CacheFormatNodes(nodes)
		if err != nil {
			ctx.Error = jas.NewInternalError(err)
			l.Err(err)
			return
		}
		ctx.Data = mappedNodes
	}
}

示例2: GetNode

// GetNode retrieves a single node from the database, removes
// sensitive data (such as an email address) and sets ctx.Data to
// it. If `?geojson` is set, then it returns it in geojson.Feature
// form.
func (*Api) GetNode(ctx *jas.Context) {
	ip := IP(net.ParseIP(ctx.RequireStringLen(0, 40, "address")))
	if ip == nil {
		// If this is encountered, the address was incorrectly
		// formatted.
		ctx.Error = jas.NewRequestError("addressInvalid")
		return
	}
	node, err := Db.GetNode(ip)
	if err != nil {
		// If there has been a database error, log it and report the
		// failure.
		ctx.Error = jas.NewInternalError(err)
		l.Err(err)
		return
	}
	if node == nil {
		// If there are simply no matching nodes, set the error and
		// return.
		ctx.Error = jas.NewRequestError("No matching node")
		return
	}

	// We must invoke ParseForm() so that we can access ctx.Form.
	ctx.ParseForm()

	// If the form value 'geojson' is included, dump in GeoJSON
	// form. Otherwise, just dump with normal marhshalling.
	if _, ok := ctx.Form["geojson"]; ok {
		ctx.Data = node.Feature()
		return
	} else {
		// Only after removing any sensitive data, though.
		node.OwnerEmail = ""

		// Finally, set the data and exit.
		ctx.Data = node
	}
