When the control leaves the block of the using statement, an acquired IDisposable instance is disposed. In particular, the using statement ensures that a disposable instance is disposed even if an exception occurs within the block of the using statement. In the preceding example, an opened file is closed after all lines are processed.
You can also use the using statement and declaration with an instance of a ref struct that fits the disposable pattern. That is, it has an instance Dispose method, which is accessible, parameterless and has a void return type.
In the preceding example, after control leaves the using statement, a disposable instance remains in scope while it's already disposed. If you use that instance further, you might encounter an exception, for example, ObjectDisposedException. That's why we recommend declaring a disposable variable within the using statement or with the using declaration.
To run any of the code samples in this document, you'll need a Google account, access to the Internet, and a web browser. If you are using one of the API client libraries, also see the language-specific requirements below.
You can use this parameter for several purposes, such as directing the user to the correct resource in your application, sending nonces, and mitigating cross-site request forgery. Since your redirect_uri can be guessed, using a state value can increase your assurance that an incoming connection is the result of an authentication request. If you generate a random string or encode the hash of a cookie or another value that captures the client's state, you can validate the response to additionally ensure that the request and response originated in the same browser, providing protection against attacks such as cross-site request forgery. See the OpenID Connect documentation for an example of how to create and confirm a state token.
The code constructs a Flow object, which identifies your application using information from the client_secret.json file that you downloaded after creating authorization credentials. That object also identifies the scopes that your application is requesting permission to access and the URL to your application's auth endpoint, which will handle the response from Google's OAuth 2.0 server. Finally, the code sets the optional access_type and include_granted_scopes parameters.
Google's OAuth 2.0 server authenticates the user and obtains consent from the user for your application to access the requested scopes. The response is sent back to your application using the redirect URL you specified.
When refreshing an access token or using incremental authorization, the token may have expired or has been invalidated. Authenticate the user again and ask for user consent to obtain new tokens. If you are continuing to see this error, ensure that your application has been configured correctly and that you are using the correct tokens and parameters in your request. Otherwise, the user account may have been deleted or disabled.
A call to the drive.files endpoint (the Drive Files API) using the Authorization: Bearer HTTP header might look like the following. Note that you need to specify your own access token:GET /drive/v2/files HTTP/1.1Host: www.googleapis.comAuthorization: Bearer access_tokenHere is a call to the same API for the authenticated user using the access_token query string parameter:
This Python example uses the Flask framework and the Requests library to demonstrate the OAuth 2.0 web flow. We recommend using the Google API Client Library for Python for this flow. (The example in the Python tab does use the client library.)
To begin, obtain OAuth 2.0 client credentials from the Google API Console. Then your client application requests an access token from the Google Authorization Server, extracts a token from the response, and sends the token to the Google API that you want to access. For an interactive demonstration of using OAuth 2.0 with Google (including the option to use your own client credentials), experiment with the OAuth 2.0 Playground.
This page gives an overview of the OAuth 2.0 authorization scenarios that Google supports, and provides links to more detailed content. For details about using OAuth 2.0 for authentication, see OpenID Connect.
Before your application can access private data using a Google API, it must obtain an access token that grants access to that API. A single access token can grant varying degrees of access to multiple APIs. A variable parameter called scope controls the set of resources and operations that an access token permits. During the access-token request, your application sends one or more values in the scope parameter.
There are several ways to make this request, and they vary based on the type of application you are building. For example, a JavaScript application might request an access token using a browser redirect to Google, while an application installed on a device that has no browser uses web service requests.
Administrators of GCP organizations might require frequent reauthentication of users while they access GCP resources, using the Google Cloud session control feature. This policy impacts access to Google Cloud Console, the Google Cloud SDK (also known as the gcloud CLI), and any third party OAuth application that requires the Cloud Platform scope. If a user has a session control policy in place then on the expiry of the session duration, your API calls will error out similar to what would happen if the refresh token was revoked - the call will fail with an error type invalid_grant; the error_subtype field can be used to distinguish between a revoked token and a failure due to a session control policy (for example, "error_subtype": "invalid_rapt"). As session durations can be very limited (between 1 hour to 24 hours), this scenario must be handled gracefully by restarting an auth session.
This course is the first of a two-course sequence: Introduction to Computer Science and Programming Using Python, and Introduction to Computational Thinking and Data Science. Together, they are designed to help people with no prior exposure to computer science or programming learn to think computationally and write programs to tackle useful problems. Some of the people taking the two courses will use them as a stepping stone to more advanced computer science courses, but for many it will be their first and last computer science courses. This run features lecture videos, lecture exercises, and problem sets using Python 3.5. Even if you previously took the course with Python 2.7, you will be able to easily transition to Python 3.5 in future courses, or enroll now to refresh your learning.
Bind application-level middleware to an instance of the app object by using the app.use() and app.METHOD() functions, where METHOD is the HTTP method of the request that the middleware function handles (such as GET, PUT, or POST) in lowercase.
To skip the rest of the middleware functions from a router middleware stack, call next('route') to pass control to the next route.NOTE: next('route') will work only in middleware functions that were loaded by using the app.METHOD() or router.METHOD() functions.
If you use ufw or firewalld to manage firewall settings, be aware thatwhen you expose container ports using Docker, these ports bypass yourfirewall rules. For more information, refer toDocker and ufw.
Docker provides a convenience script at _in_new to install Docker intodevelopment environments non-interactively. The convenience script isn'trecommended for production environments, but it's useful for creating aprovisioning script tailored to your needs. Also refer to theinstall using the repository steps to learnabout installation steps to install using the package repository. The source codefor the script is open source, and you can find it in thedocker-install repository on GitHubopen_in_new.
You have now successfully installed and started Docker Engine. The dockerservice starts automatically on Debian based distributions. On RPM baseddistributions, such as CentOS, Fedora, RHEL or SLES, you need to start itmanually using the appropriate systemctl or service command. As the messageindicates, non-root users can't run Docker commands by default.
If you installed Docker using the convenience script, you should upgrade Dockerusing your package manager directly. There's no advantage to re-running theconvenience script. Re-running it can cause issues if it attempts to re-installrepositories which already exist on the host machine.
