在全球依赖云计算的今天，亚马逊AWS的任何一次抖动，几乎都意味着互联网世界的一次地震。 就在美西时间 10月20日下午，一场毫无预兆的互联网大崩溃事件真的席卷了全球。 并且持续超过15个小时，波及了全球数以千万计、各行各业的企业与用户。 业内形容此次宕机为"半个互联网陷入不可用状态"，波及范围之广，堪称近年来最严重的AWS事件之一。 还有网友调侃称，"亚马逊打个喷嚏，半个互联网都感冒了。" 故障根源方面，亚马逊云服务官方指出， 故障发生在该公司位于弗吉尼亚州北部的庞大数据中心区域US-EAST-1。 US-EAST-1 是其运营历史最久、规模最大、最繁忙的数据中心集群，许多全球性的应用程序和网站都托管于此。 问题与"DynamoDB API的DNS解析"有关，即系统无法正确找到名为DynamoDB的关键数据库服务的网络地址。 此次受到影响的主要产品包括亚马逊旗下网站、多邻国、 Snapchat、Reddit、 迪士尼+、Apple TV、Roblox、堡垒之夜、Steam、 PlayStation、Xbox、育碧、Cursor、Docker、Postman等热门网站。 Robinhood、 Coinbase、 ...

Core Insights - The article explains the concept of Webhook in simple terms, comparing it to a "doorbell" for systems to notify each other in real-time, eliminating the need for constant polling [2][10][12]. Group 1: Understanding Webhook - Webhook is described as a "reverse" API that allows systems to send notifications to each other without the need for constant inquiries [10][12]. - The traditional API method requires users to actively check for updates, which is inefficient and resource-consuming [6][7]. - Webhook simplifies this process by allowing systems to push notifications when specific events occur, such as payment confirmations [12][14]. Group 2: Installation and Functionality - Setting up a Webhook involves three main steps: providing a Callback URL, specifying the events to subscribe to, and handling incoming notifications [17][20][23]. - The Callback URL acts as the "address" where notifications will be sent, and it must be configured in the system that will send the notifications [18][19]. - The system sends an HTTP POST request containing a Payload with relevant information when an event occurs [24][26]. Group 3: Common Pitfalls - Security is a major concern, as the Webhook URL is publicly accessible, making it vulnerable to unauthorized requests [29][30]. - Implementing signature verification is crucial to ensure that notifications are legitimate and from trusted sources [33][35]. - Handling duplicate notifications is necessary to prevent processing the same event multiple times, which can lead to errors [39][40]. Group 4: Practical Implementation - The article provides a step-by-step guide for setting up a Webhook receiver using Python and Flask, including code examples [26][50][56]. - It emphasizes the importance of using tools like Ngrok to expose local servers to the internet for testing purposes [62][63]. - Postman is recommended for sending test requests to verify the Webhook functionality [70][73]. Group 5: Automation with n8n - The article concludes by demonstrating how to integrate Webhook functionality into n8n for automated workflows, allowing for seamless communication between systems [75][88]. - It highlights the shift from a "pull" model to a "push" model in system interactions, enhancing efficiency and responsiveness [85].

To recap, there are the steps:- Open Postman's MCP generator.- Select the APIs from Postman's API Network.- All these APIs will be available as tools in your MCP server.- Download the code provided by Postman.- Specify API keys if needed in the .env file.- Prepare your MCP config file JSON and add it to Claude/Cursor.Done!Thanks to @getpostman for working with me on this thread! ...

Core Viewpoint - Requestly is presented as a versatile API client tool that combines HTTP interception, request modification, interface testing, and data simulation, claiming to be permanently free and fully open-source [4][6][12]. Features Overview - Requestly offers a comprehensive set of capabilities for developers, including collection management, multi-environment variables, complete request history, a visual interface, and collaboration features [7]. - Unlike many cloud-dependent tools, Requestly prioritizes local storage, allowing users to manage collections, switch environments, and run scripts similarly to Postman, while also providing real-time interception and modification of requests and responses like Charles [8]. - Advanced capabilities such as dynamic simulation, delay injection, and script control enhance API debugging and frontend development [9]. User Interface and Functionality - The interface features a three-column layout with a collection tree on the left, request parameters in the middle, and response data on the right, with all data stored locally in Git-tracked JSON files [14]. - Users can seamlessly switch between multiple environments (development, testing, production) using a dropdown menu, supporting both global and collection-level variables [16][17]. - The tool allows for easy creation of new requests or batch imports from formats like cURL, Postman collections, and OpenAPI [20]. HTTP Interception and Mocking - Requestly includes an HTTP interceptor that captures and modifies any HTTPS requests and responses, enabling real-time monitoring and editing [28]. - Users can create local or cloud-based mock APIs that support REST and GraphQL, allowing frontend developers to work without waiting for backend services [30].

Core Viewpoint - The article discusses the increasing importance and variety of API client tools in 2025, highlighting their efficiency and user-friendliness for developers. Group 1: Popular API Client Tools - Postman is a widely used API debugging tool known for its user-friendly interface and comprehensive features, including request building, documentation, and testing assertions [4][5]. - Insomnia is an open-source, lightweight API client that supports REST, GraphQL, and gRPC, designed for developers seeking a simple and efficient interface [8][9]. - Paw is a macOS-specific API client with a beautiful interface and full functionality, including request building and team collaboration features [11][12]. - Hoppscotch is a lightweight, open-source API client that operates in the browser, supporting modern protocols like WebSocket and GraphQL [14]. - Bruno is a new open-source API client that emphasizes offline functionality and project-based request management, suitable for developers concerned about privacy [16][18]. - Apifox is a Chinese API ecosystem tool that integrates API documentation, debugging, mocking, and testing, with a user-friendly design for local developers [19]. - Apipost is another Chinese API client focusing on debugging, documentation generation, and team collaboration, featuring a modern interface [21][22]. - Thunder Client is a lightweight API client plugin for VS Code, allowing developers to debug APIs directly within their coding environment [24][25]. - Advanced REST Client (ARC) is an open-source API debugging tool that has transitioned from a Chrome extension to a standalone desktop application, maintaining its comprehensive functionality [26][27]. - HTTPie is a user-friendly API client that emphasizes human readability, available in both desktop and web versions, supporting REST and GraphQL [28][29].
