Policy Syntax
The following uses a custom policy for OBS as an example to describe the syntax.
{ "Version": "1.1", "Statement": [ { "Effect": "Allow", "Action": [ "obs:bucket:ListAllMyBuckets", "obs:bucket:HeadBucket", "obs:bucket:ListBucket", "obs:bucket:GetBucketLocation" ], "Condition": { "StringEndWithIfExists": { "g:UserName": [ "specialCharacter" ] }, "Bool": { "g:MFAPresent": [ "true" ] } }, "Resource": [ "obs:*:*:bucket:*" ] } ] }
Policy Structure
A policy consists of a version and one or more statements (indicating different actions).

Policy Parameters
Policy parameters include Version and Statement, which are described in the following table. You can create custom policies by specifying the parameters. For details, see Custom Policy Use Cases.
Parameter |
Description |
Value |
|
---|---|---|---|
Version |
Policy version. |
1.1: indicates policy-based access control. |
|
Statement |
Effect |
Determines whether to allow or deny the operations defined in the action. |
If an action has both Allow and Deny effects, the Deny effect takes precedence. |
Action |
Operations to be performed on the service. |
Format: "Service name:Resource type:Operation". Wildcard characters (*) are supported, indicating all options. Example: obs:bucket:ListAllMybuckets: Permissions for listing all OBS buckets. View all actions of the service in its API Reference. |
|
Condition |
Determines when a policy takes effect. A condition consists of a condition key and an operator. |
Format: "Condition operator:{Condition key:[Value 1,Value 2]}" If you set multiple conditions, the policy takes effect only when all the conditions are met. Example: StringEndWithIfExists":{"g:UserName":["specialCharacter"]}: The statement is valid for users whose names end with specialCharacter. |
|
Resource |
Resources on which the policy takes effect. |
Format: Service name:Region:Account ID:Resource type:Resource path. Wildcard characters (*) are supported. Example:
|
- Condition key
A condition key is a key in the Condition element of a statement. There are global and service-level condition keys.
- Global condition keys (starting with g:) apply to all operations. IAM provides common global condition keys and special global condition keys.
- Common global condition keys: Cloud services do not need to provide user identity information. Instead, IAM automatically abstracts user information and authenticates users. For details, see Common global condition keys.
- Special global condition keys: IAM obtains condition information from cloud services for authentication.
- Service-level condition keys (starting with a service name abbreviation, for example, obs:) apply only to operations on the specified service. For details, see the user guide of the corresponding cloud service.
Table 2 Common global condition keys Global Condition Key
Type
Description
g:CurrentTime
Time
Time when an authentication request is received. The time is in ISO 8601 format, for example, 2012-11-11T23:59:59Z.
g:DomainName
String
Account name.
g:MFAPresent
Boolean
Whether to obtain a token through MFA authentication.
g:MFAAge
Number
Validity period of a token obtained through MFA authentication. This condition must be used together with g:MFAPresent.
g:ProjectName
String
Project name.
g:ServiceName
String
Service name.
g:UserId
String
IAM user ID.
g:UserName
String
IAM user name.
- Global condition keys (starting with g:) apply to all operations. IAM provides common global condition keys and special global condition keys.
- Operator
An operator (see Operators), a condition key, and a condition value together constitute a complete condition statement. A policy takes effect only when its request conditions are met. The operator suffix IfExists indicates that a policy takes effect if a request value is empty or meets the specified condition. For example, if the operator StringEqualsIfExists is selected for a policy, the policy takes effect if a request value is empty or equal to the specified condition value.
