Request message
An HTTP request is a message sent by a client to a server that specifies a method and target and may include headers and a body.
Rust Servers, Services, and Apps
POST is an HTTP method that submits data for processing by a target resource.
- How it is used
- Carries client data to routed handlers for form processing, authentication, and course creation.
- How deep it goes
- Works through typed request parsing and POST handlers, while limiting the hand-built parser to GET and POST.
- Examples
- Uses a parsed GET request, a POST sign-in form, and a curl POST that creates a course.
- What you can do after
- Build it from scratch as a typed Rust request, then apply it via Actix handlers to process POST data.

Learn Go with Pocket-Sized Projects
POST is an HTTP method for submitting data or requesting a server-side action that may change state.
- How it is used
- Uses request messages to invoke game-creation and habit-creation endpoints.
- How deep it goes
- Works through method-and-path selection, curl checks, method rejection, and form submission; does not detail HTTP message parsing.
- Examples
- Shows POST and GET requests to `/games` with curl, plus a POST form with named habit inputs.
- What you can do after
- Build it from scratch: route a POST request to a Go handler and check its response with curl or an HTTP handler test.

Pro ASP.NET Core 7, Tenth Edition
An HTTP POST request is an HTTP request that submits data to a server for processing or resource modification, often causing a state-changing operation.
- How it is used
- Handles submitted form data and state-changing operations through controllers, Razor Pages, and web-service endpoints.
- How deep it goes
- Works through form configuration, method-specific handlers, binding, anti-forgery protection, and redirects, but not the request’s wire format.
- Examples
- Uses an RSVP form, shopping-cart buttons, and a product-price editor to show submitted values reaching handlers.
- What you can do after
- Build it from scratch by pairing a POST form with a controller action or Razor Page handler and redirecting after processing.

A Pythonic Adventure: From Python basics to a working web app
The POST method is an HTTP request method for submitting data to a web server for processing.
- How it is used
- Uses POST when a browser submits form data for server-side processing.
- How deep it goes
- Explains form configuration, route handling, request parsing, and response rendering, but stops short of broader HTTP internals.
- Examples
- Demonstrates a drink-order form that submits coffee or decaf and displays the selected order.
- What you can do after
- Apply it via Flask to accept submitted form values and render a response containing them.

The Well-Grounded Python Developer: How the pros use Python and Flask
An HTTP POST request is an HTTP request that submits data to a server for processing or resource creation.
- How it is used
- Connects browser actions to server processing, especially when HTML forms submit login or password-reset data.
- How deep it goes
- Shows a GET message and works through form-based POST handling, while leaving the full HTTP protocol definition out of scope.
- Examples
- Uses a GET request listing, a login form submitting email and password, and GET and POST password-reset handlers.
- What you can do after
- Apply it via Flask routes and form handlers to receive POST submissions and validate their inputs.
Elasticsearch in Action, Second Edition
The POST method is an HTTP request method used to submit data to a server for processing or resource creation.
- How it is used
- Indexes documents without client-provided IDs and can submit Elasticsearch search requests with JSON payloads.
- How deep it goes
- Explains POST through endpoint forms, JSON examples, generated IDs, and its interchangeable search-request use with GET.
- Examples
- Uses an untitled Elasticsearch document, a movie review, and searches whose payloads may include queries, sorting, and highlighting.
- What you can do after
- Apply it via Elasticsearch document and search APIs by posting JSON when IDs are generated or when POST is preferred for searches.

Building Web APIs with ASP.NET Core
POST is an HTTP request method for creating a resource or causing a state change.
- How it is used
- Uses POST to create resources or perform state changes, including non-idempotent board-game updates.
- How deep it goes
- Explains POST semantics, idempotence-based method selection, DTO input, validation, persistence, and response construction.
- Examples
- Uses a BoardGameController endpoint that changes board game ID 181 from Risk! to Risk and from 1980 to 1959.
- What you can do after
- Apply POST by implementing a DTO-backed controller action that updates a record, persists changes, and returns the result.

ASP.NET Core in Action, 3e
POST is an HTTP method used to send data to a server for processing or resource creation.
- How it is used
- Uses HTTP request messages to send data, select endpoint behavior, and create or modify server-side resources.
- How deep it goes
- Explains verbs, endpoint mapping, request access, and binding order, but stops short of detailing HTTP wire-format fields.
- Examples
- Uses form submission, MapPost endpoints, HttpRequest parameters, and a minimal API verb-operation table.
- What you can do after
- Apply it via ASP.NET Core minimal APIs by choosing POST appropriately, mapping an endpoint, and binding incoming values.
