Sends a file to one or more Elastic Compute Service (ECS) instances.

Operation description

Usage notes

The instances to which you want to send a file must be in the Running (Running) state.
Cloud Assistant Agent must be installed on the instances.
Only Cloud Assistant Agent versions that are later than the following ones support file sending. If the ClientNeedUpgrade error code is returned, update Cloud Assistant Agent to the latest version.
- For Linux instances, the version of Cloud Assistant Agent must be later than 1.0.2.569.
- For Windows instances, the version of Cloud Assistant Agent must be later than 1.0.0.149.
The file to be sent must not exceed 32 KB in size after it is encoded in Base64.
The file may fail to be sent due to instance exceptions, network exceptions, or exceptions on Cloud Assistant Agent. If the file fails to be sent, call the DescribeSendFileResults operation or see Check execution results and troubleshoot common issues for troubleshooting.

Debugging

You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.

The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

Operation: the value that you can use in the Action element to specify the operation on a resource.
Access level: the access level of each operation. The levels are read, write, and list.
Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
- The required resource types are displayed in bold characters.
- If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
Condition Key: the condition key that is defined by the cloud service.
Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.

Request parameters

Parameter	Type	Required	Description	Example
RegionId	string	Yes	The region ID of the instance to which to send the file. You can call the DescribeRegions operation to query the most recent region list.	cn-hangzhou
ResourceGroupId	string	No	The ID of the resource group. When you specify this parameter, take note of the following items: The instance specified by the InstanceId parameter must belong to the specified resource group. If you specify this parameter, you can call the DescribeSendFileResults operation to query file sending results in the specified resource group.	rg-bp67acfmxazb4p****

Overwrite	boolean	No	Specifies whether to overwrite a file in the destination directory if the file has the same name as the sent file. true false Default value: false.	true
InstanceId	array	Yes	The IDs of instances to which to send the file. You can specify up to 50 instance IDs in each request. Valid values of N: 1 to 50.
	string	Yes	The ID of instance N to which to send the file. You can specify up to 50 instance IDs in each request. Valid values of N: 1 to 50.	i-bp185dy2o3o6n****
