As described in RFC 2606 and RFC 6761, anumber of domains such as example.com and example.org are maintainedfor documentation purposes. These domains may be used as illustrativeexamples in documents without prior coordination with us. They are notavailable for registration or transfer.
We provide a web service on the example domain hosts to provide basicinformation on the purpose of the domain. These web services areprovided as best effort, but are not designed to support productionapplications. While incidental traffic for incorrectly configuredapplications is expected, please do not design applications that requirethe example domains to have operating HTTP service.
The below combobox for choosing the name of a US state or territory demonstrates the Combobox Pattern. The design pattern describes four types of autocomplete behavior. This example illustrates the autocomplete behavior known as list autocomplete with manual selection. If the user types one or more characters in the edit box and the typed characters match the beginning of the name of one or more states or territories, a listbox popup appears containing the matching names. When the listbox appears, a suggested name is not automatically selected. Thus, after typing, if the user tabs or clicks out of the combobox without choosing a value from the listbox, the typed string becomes the value of the combobox. Note that this implementation enables users to input the name of a state or territory, but it does not prevent input of any other arbitrary value.
The example combobox on this page implements the following keyboard interface. Other variations and options for the keyboard interface are described in the Keyboard Interaction section of the Combobox Pattern.
The example combobox on this page implements the following ARIA roles, states, and properties. Information about other ways of applying ARIA roles, states, and properties is available in the Roles, States, and Properties section of the Combobox Pattern.
This section presents examples of typical use cases for bucket policies. These sample policies use DOC-EXAMPLE-BUCKET as the resource value. To test these policies, replace the user input placeholders with your own information (such as your bucket name).
To grant or deny permissions to a set of objects, you can use wildcard characters (*) in Amazon Resource Names (ARNs) and other values. For example, you can control access to groups of objects that begin with a common prefix or end with a given extension, such as .html.
The following example policy requires every object that is written to the bucket to be encrypted with server-side encryption using AWS Key Management Service (AWS KMS) keys (SSE-KMS). If the object isn't encrypted with SSE-KMS, the request will be denied.
The following example policy grants the s3:PutObject and s3:PutObjectAcl permissions to multiple AWS accounts and requires that any requests for these operations must include the public-read canned access control list (ACL). For more information, see Amazon S3 actions and Amazon S3 condition key examples.
The following example shows how to allow another AWS account to upload objects to your bucket while ensuring that you have full control of the uploaded objects. This policy grants a specific AWS account (111122223333) the ability to upload objects only if that account includes the bucket-owner-full-control canned ACL on upload. The StringEquals condition in the policy specifies the s3:x-amz-acl condition key to express the canned ACL requirement. For more information, see Amazon S3 condition key examples.
The following example policy grants a user permission to perform the s3:PutObjectTagging action, which allows a user to add tags to an existing object. The condition uses the s3:RequestObjectTagKeys condition key to specify the allowed tag keys, such as Owner or CreationDate. For more information, see Creating a condition that tests multiple key values in the IAM User Guide.
The following example policy grants a user permission to perform the s3:PutObjectTagging action, which allows a user to add tags to an existing object. The condition requires the user to include a specific tag key (such as Project) with the value set to X.
The following example policy grants a user permission to perform the s3:PutObject action so that they can add objects to a bucket. However, the Condition statement restricts the tag keys and values that are allowed on the uploaded objects. In this example, the user can only add objects that have the specific tag key (Department) with the value set to Finance to the bucket.
In the following example bucket policy, the aws:SourceArn global condition key is used to compare the Amazon Resource Name (ARN) of the resource, making a service-to-service request with the ARN that is specified in the policy. The aws:SourceArn global condition key is used to prevent the Amazon S3 service from being used as a confused deputy during transactions between services. Only the Amazon S3 service is allowed to add objects to the Amazon S3 bucket.
The Condition block uses the NotIpAddress condition and the aws:SourceIp condition key, which is an AWS wide condition key. The aws:SourceIp condition key can only be used for public IP address ranges. For more information about these condition keys, see Amazon S3 condition key examples. The aws:SourceIp IPv4 values use standard CIDR notation. For more information, see IAM JSON Policy Elements Reference in the IAM User Guide.
The following example bucket policy shows how to mix IPv4 and IPv6 address ranges to cover all of your organization's valid IP addresses. The example policy allows access to the example IP addresses 192.0.2.1 and 2001:DB8:1234:5678::1 and denies access to the addresses 203.0.113.1 and 2001:DB8:1234:5678:ABCD::1.
The aws:SourceIp condition key can only be used for public IP address ranges. The IPv6 values for aws:SourceIp must be in standard CIDR format. For IPv6, we support using :: to represent a range of 0s (for example, 2001:DB8:1234:5678::/64). For more information, see IP Address Condition Operators in the IAM User Guide.
Suppose that you have a website with the domain name www.example.com or example.com with links to photos and videos stored in your bucket named DOC-EXAMPLE-BUCKET. By default, all Amazon S3 resources are private, so only the AWS account that created the resources can access them.
The following example bucket policy grants JohnDoe full console access to only his folder (home/JohnDoe/). By creating a home folder and granting the appropriate permissions to your users, you can have multiple users share a single bucket. This policy consists of three Allow statements:
The following example bucket policy grants a CloudFront origin access identity (OAI) permission to get (read) all objects in your S3 bucket. You can use a CloudFront OAI to allow users to access objects in your bucket through CloudFront but not directly through Amazon S3. For more information, see Restricting access to Amazon S3 content by using an Origin Access Identity in the Amazon CloudFront Developer Guide.
The following example bucket policy grants Amazon S3 permission to write objects (PUT requests) to a destination bucket. You use a bucket policy like this on the destination bucket when setting up an S3 Storage Lens metrics export.
The following example bucket policy grants Amazon S3 permission to write objects (PUT requests) from the account for the source bucket to the destination bucket. You use a bucket policy like this on the destination bucket when setting up S3 Inventory and S3 analytics export.
To restrict a user from accessing your S3 Inventory report in a destination bucket, add a bucket policy like the following example to the destination bucket. This example bucket policy denies all the principals except the user Ana from accessing the inventory report DOC-EXAMPLE-DESTINATION-BUCKET-INVENTORY in the destination bucket DOC-EXAMPLE-DESTINATION-BUCKET.
When Amazon S3 receives a request with multi-factor authentication, the aws:MultiFactorAuthAge condition key provides a numeric value that indicates how long ago (in seconds) the temporary credential was created. If the temporary credential provided in the request was not created by using an MFA device, this key value is null (absent). In a bucket policy, you can add a condition to check this value, as shown in the following example.
This example policy denies any Amazon S3 operation on the /taxdocuments folder in the DOC-EXAMPLE-BUCKET bucket if the request is not authenticated by using MFA. To learn more about MFA, see Using Multi-Factor Authentication (MFA) in AWS in the IAM User Guide.
For example, the following bucket policy, in addition to requiring MFA authentication, also checks how long ago the temporary session was created. The policy denies any operation if the aws:MultiFactorAuthAge key value indicates that the temporary session was created more than an hour ago (3,600 seconds).
Matplotlib supports event handling witha GUI neutral event model, so you can connect to Matplotlib events withoutknowledge of what user interface Matplotlib will ultimately be plugged in to.This has two advantages: the code you write will be more portable, andMatplotlib events are aware of things like data coordinate space and whichaxes the event occurs in so you don't have to mess with low leveltransformation details to go from canvas space to data space. Object pickingexamples are also included.
When embedding Matplotlib in a GUI, you must use the Matplotlib APIdirectly rather than the pylab/pyplot procedural interface, so take alook at the examples/api directory for some example code working withthe API.
Note also that these modules demonstrate internals for Drupal development in PHP (and some JavaScript). Not all Drupal users will need these examples. There are many contributed modules which will do the majority of what a Drupal site-builder could need. Be sure and explore other contributed modules to see if you can find one that meets your needs.
