request parameters

Request parameters are a collection of data used to pass specific instructions to the server in network communications, covering multiple transmission forms such as URL query parameters, request headers, and message bodies. Under the HTTP protocol framework, these parameters accurately control data interaction behavior through key-value pair structures, and their design quality directly affects the success rate of API calls and system performance. IP2world's dynamic proxy service provides a stable network channel for high-frequency parameter transmission, ensuring the reliable execution of large-scale requests.1. Technical classification and transmission mechanism of request parameters1.1 Basic parameter typesQuery Parameters: Key-value pairs appended after the question mark in the URL, with a length limit of 2083 charactersPath Parameters: Dynamic variables embedded in the URL path (such as /user/{id})Request header parameters (Headers): control caching, authentication, content negotiation and other meta informationMessage body parameters (Body): Supports encoding formats such as JSON/XML/form-data1.2 Coding and Security SpecificationsURL encoding converts special characters (spaces to %20)JWT token implements parameter signature tamper-proofSensitive fields are forced to be transmitted over HTTPS (TLS 1.3 protocol)1.3 Performance Optimization StrategyBatch parameter compression (GZIP compression rate can reach 70%)Persistent connection reuse TCP channelUse IP2world static ISP proxy to reduce DNS query time2.
