public class GreetingController {

//解析application/json @RequestMapping(value = "https://www.it610.com/hello", method = RequestMethod.POST) public Object getJson(@RequestBody Object obj) { return obj; }

}
客户端，原生ajax

var xhr = new XMLHttpRequest() xhr.onreadystatechange = function (ev) { console.log(xhr.readyState); if (xhr.readyState === 4){ if (xhr.status === 200){ console.log(xhr.responseText); } else { console.error(xhr.statusText); } } }; xhr.open('POST','/hello'); xhr.setRequestHeader('Content-Type', 'application/json'); xhr.send(JSON.stringify({ name:'zhuwei', age:'25', hobby:'ball'}))

application/x-www-form-urlencoded
效劳端，springboot
@RestController
public class GreetingController {

//解析application/x-www-form-urlencoded @RequestMapping(value = "https://www.it610.com/helloFormUrl", method = RequestMethod.POST) public String getForm(@RequestParam("name") String name,@RequestParam("age") String age) { return "name="+name+"&"+"age="+age; }

}
客户端，html form 表单

【Vite 从入门到精通，玩转新时代前端构建法则】或者运用 ajax

var xhr = new XMLHttpRequest() xhr.onreadystatechange = function (ev) { console.log(xhr.readyState); if (xhr.readyState === 4){ if (xhr.status === 200){ console.log(xhr.responseText); } else { console.error(xhr.statusText); } } }; //生成 post 参数 params，有三种办法，选一种 //1. 运用URLSearchParams 接口,会对内容停止utf8编码 const params = new URLSearchParams(); params.append('name', '小明'); params.append('age', '18'); //2.运用encodeURIComponent 对内容停止编码 //益处是url中的汉字等一些特殊字符会被转为utf8编码，减少出错 const params = "name="+encodeURIComponent("小明")+"&age="+encodeURIComponent("19")//3.不编码直接写，可能效劳端会解码错误 const params = "name=小明&age=19"xhr.open('POST','http://localhost:1234/helloFormUrl'); xhr.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded'); xhr.send(params)
