search json javascrip -s turn gpo pre ica use

當參數為對象時，參數在request payload裏，content-type為application/json;charset=UTF-8，這樣springmvc是不能通過

request.getParameterMap();獲取的
解決辦法一，
參數通過

URLSearchParams設置

let param = new URLSearchParams();
param.append("username", "admin");
param.append("password", "admin");

方法二，
修改axios源碼
-axios
--lib
---defaults.js

defaults.js文件裏transformRequest方法中

if (utils.isObject(data)) { //setContentTypeIfUnset(headers, ‘application/json;charset=utf-8‘); //return JSON.stringify(data); setContentTypeIfUnset(headers, ‘application/x-www-form-urlencoded;charset=utf-8‘); let keys2 = Object.keys(data); /* 這裏就是把json變成url形式，並進行encode */ //console.log(‘key====‘, keys2) return encodeURI(keys2.map(name => `${name}=${data[name]}`).join(‘&‘)); } 這樣就可以了

axios發送post請求,默認的content-type
