Cpr
C++ is a high-level HTTP client library and wrapper for libcurl. It provides a C++ interface for making network requests, managing network sessions, and implementing data transfers.
The library distinguishes itself by offering an asynchronous HTTP client capable of executing non-blocking requests via callback interfaces. It also functions as a multipart form uploader for transmitting files and structured data, as well as an SSE stream handler for processing real-time server-sent events over persistent connections.
Its broader capabilities cover secure web communication through SSL encryption and request authentication. It includes tools for session state management via cookie persistence, proxy routing, and request timeout control.
The implementation utilizes RAII resource management to handle the lifecycle of network handles and session objects.
Features
- HTTP Client Libraries - Implements a modern C++ interface for performing synchronous and asynchronous HTTP requests and managing sessions.
- HTTP Method Executions - Enables sending network requests using standard HTTP methods like GET, POST, PUT, DELETE, and PATCH.
- Asynchronous HTTP Clients - Provides a non-blocking HTTP client capable of executing requests in the background via callbacks.
- C++ Networking Libraries - Provides a simplified C++ networking library for making HTTP requests and interacting with web services.
- libcurl Wrappers - Wraps the low-level C API of libcurl to provide a high-level C++ interface for HTTP transport.
- Secure Communication Protocols - Establishes encrypted connections and manages authentication to protect data in transit via SSL.
- Session Management - Maintains state, cookies, and authentication across multiple network requests to handle user sessions.
- Session State Management - Maintains synchronization and session state between clients and servers using persistent cookie tracking.
- Asynchronous Request Execution - Provides non-blocking network request execution using asynchronous patterns to prevent main thread blocking.
- HTTP Cookie Persistence - Stores and retrieves HTTP cookies from local files to maintain session state across separate request executions.
- Asynchronous Network Callbacks - Executes network requests in background threads and notifies the caller via user-defined callback functions.
- API Request Configurations - Provides utilities for configuring request metadata, including custom headers, timeout limits, and proxy settings.
- Asynchronous API Clients - Handles background network operations and data parsing to keep applications responsive.
- Multipart File Uploads - Supports uploading files and multipart data to servers with integrated progress tracking.
- Multipart Form Uploaders - Enables the construction and transmission of HTTP multipart/form-data requests for uploading files.
- Multipart Form Uploads - Implements transmission of binary data and files using the HTTP multipart/form-data encoding standard.
- Real-time Event Streams - Implements server-sent events and push notification mechanisms for receiving real-time data updates.
- Request Header Configuration - Provides comprehensive tools for defining and managing custom HTTP request headers.
- Server-Sent Events - Processes real-time streaming data received from servers via persistent Server-Sent Event connections.
- SSE Consumers - Implements a client for processing real-time server-sent event streams over persistent HTTP connections.
- RAII Resource Management - Uses RAII to automatically manage the lifecycle of network handles and session objects, preventing resource leaks.
- HTTP Header and Parameter Management - Allows attaching custom headers and encoding parameters into URL-encoded formats for server communication.
- DevOps & Infrastructure - C++ requests library
