示例1: Set
// Set implements Cache.
func (cache *Cache) Set(key string, im *imageserver.Image, params imageserver.Params) error {
data, err := im.MarshalBinary()
if err != nil {
return err
}
return cache.setData(key, data)
}示例2: parseResponse
func parseResponse(response *http.Response) (*imageserver.Image, error) {
if response.StatusCode != http.StatusOK {
return nil, &imageserver.ParamError{
Param: imageserver.SourceParam,
Message: fmt.Sprintf("http status code %d while downloading", response.StatusCode),
}
}
