API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.
2. Input Parameters
The following request parameter list only provides API request parameters and some common parameters. For the complete common parameter list, see Common Request Parameters.
This document describes the parameters for Signature V1. It's recommended to use the V3 signature, which provides higher security. Note that for Signature V3, the common parameters need to be placed in the HTTP Header. See details.
| Parameter Name | Required | Type | Description |
|---|---|---|---|
| Action | Yes | String | Common parameter. The value used for this API: SubmitJob. |
| Version | Yes | String | Common parameter. The value used for this API: 2017-03-12. |
| Region | Yes | String | Common parameter. For more information, please see the list of regions supported by the product. |
| Placement | Yes | Placement | Location information of the submitted job. This parameter allows you to specify information such as the availability zone of the CVM instance with which the job is associated. |
| Job | Yes | Job | Job information |
| ClientToken | No | String | The string used to guarantee the idempotency of the request, which is generated by the user and must be unique for different requests. The maximum length is 64 ASCII characters. If this parameter is not specified, the idempotency of the request cannot be guaranteed. |
3. Output Parameters
| Parameter Name | Type | Description |
|---|---|---|
| JobId | String | When a job is submitted through this API, this parameter is returned and indicates the job ID. Returning the list of job IDs does not mean that the job is parsed/executed successfully. The job state can be queried using the DescribeJob API. |
| RequestId | String | The unique request ID, which is returned for each request. RequestId is required for locating a problem. |
