This example demonstrates how to send POST requests with curl using both `application/x-www-form-urlencoded` and `application/json` content types. It shows curl commands with the `-d` option for inline data and for reading from sample `data.txt` and `data.json` files, paired with explicit `-H` headers and `-X POST`. The accompanying `server.js` uses Express and body-parser middleware to receive and log the request bodies at the `/data` endpoint, while `package.json` lists the required dependencies. The visualization clarifies the correspondence between curl’s data flags and the server’s parsing behavior.

curl POST examples

This example demonstrates how to send POST requests with curl using both `application/x-www-form-urlencoded` and `application/json` content types. It shows the curl options for specifying request methods (`-X POST`), data (`-d`), headers (`-H`), and file-based payloads via `@data.txt` or `@data.json`. The accompanying Express server uses `body-parser` to parse incoming request bodies and log them to the console, providing a concrete test target for the curl commands.

cURL tips

This example demonstrates a practical cURL command for creating a user account via a REST API. It shows a POST request to the `/signup` endpoint, explicitly setting both `Accept` and `Content-Type` headers to `application/json`. The request body is piped from standard input using the `-d @-` flag, with the JSON payload containing an email and birthday. The example relies on the cURL command-line tool and the HTTP protocol, with no JavaScript libraries or rendering involved. It highlights the correct syntax for sending JSON data from a terminal without needing a separate file.

buzzPost CURL example to send a message

This example demonstrates how to send a message to a hub using a simple curl command in a shell script. It shows a single HTTP POST request that transmits a JSON payload containing a channel identifier and a “Hello world!” message to the specified endpoint. The script relies on the curl command-line tool, which handles the request, and explicitly sets the data format and HTTP method. The example is straightforward, illustrating the minimal syntax required to post structured data to a remote server without any additional libraries or visualization components.

This example demonstrates HTTP request and response interactions with the httpbin.org testing service, showing how GET and POST requests return JSON payloads with different parameters. It uses raw HTTP/1.1 protocol calls to the /anything endpoint, with visual separation of request headers, response headers, and body content. The gist displays three scenarios: a simple GET without parameters, a GET with a URL query string, and a POST with a custom body, all returning metadata about the request in JSON format. The code relies on standard HTTP libraries to make these calls, though the implementation details are not shown in the file itself.

express sample and quick examples and descriptions of body, params, and query

This example demonstrates the differences between `req.body`, `req.params`, and `req.query` in ExpressJS, showing how each carries client data to the server. The code pairs ReactJS frontend components with Axios requests against a backend using ExpressJS and body-parser. It illustrates POST/PUT/PATCH requests sending data in `req.body`, GET/DELETE requests embedding values in URL routes via `req.params`, and GET requests appending key-value pairs through `req.query`. The metaphor of a restaurant clarifies the client-server-database relationship.

buzzPost request example

This example demonstrates a minimal HTTP POST request sent from a browser to a remote server, using the Fetch API to transmit JSON-encoded data. The code posts to the endpoint `https://hub11.dev-labs.io` with a body containing a `channel` field set to `"alfa"` and a `data` field with the string `"Hello world!"`. It shows how to construct a structured payload with `JSON.stringify` and send it asynchronously, though it does not include any response handling or visualization. The example relies solely on the native `fetch` method, with no external libraries or rendering components.

This example demonstrates a basic Express.js web server that handles file uploads and form submissions through HTTP POST requests. The code uses the `express` framework and `connect-form` middleware to parse multipart form data. It serves an HTML form at the root route, then processes submitted text fields and optional image files on the `/` POST endpoint, logging parsed fields and files to the console before redirecting back. The form action uses `enctype="multipart/form-data"` and the server listens on port 3000.

golang web examples

This example demonstrates basic HTTP server patterns in Go, showing how to build routes with public and private endpoints. It uses the standard `net/http` package to define handlers for the root, `/post`, and `/json` routes, with middleware wrappers like `BasicAuth`, `GetOnly`, and `PostOnly` controlling access. The code includes functions for basic authentication, request method filtering, and JSON responses via `encoding/json`. A shell script runs `curl` commands to test the server’s behavior.
