在Java中发送HTTP POST请求并携带JSON数据,可以通过多种方式实现。以下是一个基于Apache HttpClient库的示例,展示了如何创建HTTP POST请求、构建包含JSON数据的请求体、发送请求并处理响应。 1. 创建Java HTTP客户端对象 首先,需要创建一个HTTP客户端对象。这里我们使用Apache HttpClient库。 java import org.apache.http...
HttpClient 是 Apache Jakarta Common 下的子项目,用来提供高效的、最新的、功能丰富的支持 HTTP 协议的客户端编程工具包,并且它支持 HTTP 协议最新的版本和建议。Java后台使用httpclient主要目的是为了模拟客户端的请求。 2、HttpClient的请求类型 实现了所有的Http请求类型,相应的类为:HttpGet、HttpPost、HttpDelete、Ht...
