Creates a task to distribute devices. The product to which the devices belong is distributed by default.

Usage notes

To distribute devices, perform the following steps:

1. Asynchronously call this operation to create a device distribution task and obtain the JobId parameter.

2. Use JobId as a request parameter and repeatedly call the QueryDeviceDistributeJob operation to obtain the Status parameter.

Note You must control the frequency of calls based on the QPS limit of the QueryDeviceDistributeJob operation.

If either of the following values is returned for the Status parameter, the distribution task ends:

  • 2: The device distribution task is completed. This return value does not indicate that the devices are distributed. To obtain the distribution result of each device, perform the next step.
  • 3: The distribution is unexpectedly interrupted. After you process the error, you can initiate a device distribution task again.

3. Use JobId that is returned in Step 1 as a request parameter and call the QueryDeviceDistributeDetail operation to obtain the File parameter. The File parameter indicates the file URL of the distribution result.

Note The file URL is valid for 10 minutes.

4. Obtain the distribution result by using the file URL. The Code parameter indicates whether a device is distributed. If the value of the Code parameter is 200, the device is distributed.

If the distribution fails, you can perform the preceding steps to distribute devices again.
