Adding an Image

Function

You can use the API to import an image to the image library. The image can be stored in an OBS bucket in the same region or in the request body. Only the images in the image library can be searched for.

  • To add or search for an image stored in an OBS bucket, authorize the OBS bucket first. The specific steps are as follows:

    On the Instance Management page, click Offline Import in the Operation column. The Offline Import page is displayed. Select the OBS bucket where data is stored and click Authorize. When Authorize becomes unavailable, OBS authorization is completed. For details about offline import, see Getting Started > Offline Import.

file

No

String

Base64 character string converted from the image. Only the JPEG, JPG, PNG, and BMP formats are supported. The image resolution of the narrow sides of an image must be greater than or equal to 100 pixels, and that of the wide sides cannot exceed 2048 pixels.

path

Yes

String

Image URL. This parameter is mandatory and is used as the ID of an image in the image library.

NOTE:
  • If the file field is specified, the image is obtained from file and path is used as the image index ID. If the file field does not exist or is unspecified, the image needs to be downloaded. In this case, path is the address for downloading the image (currently, images can be downloaded only from OBS in the same region as Image Search). path is also used as the image index ID.

tags

No

Object

Custom image tag. The total number of keys of each image cannot exceed 10, but the number of values corresponding to each key is not limited. For example, if a key is animal, the corresponding values can be cat, dog, and bird.

To add a tag name (key), do as follows:

  1. Log in to the ImageSearch management console, click Create Instance, and configure Customize Tag.
  2. On the instance management tab page, click an instance name. On the displayed basic information page, add a custom tag.
