前端代码 ：
$.ajax({ type:"GET", url:"http://localhost:8084/getPulbicKey", dataType:"json", success:function(data){ console.log(data); var encrypt = new JSEncrypt(); encrypt.setPublicKey(data); var encryptData = encrypt.encrypt("abc");//加密后的字符串 JSON加密
console.log(encryptData) $.ajax({ type:"GET", url:"http://localhost:8084/decrypt", dataType:"json", data:{"encrypt":encryptData}, success:function(data){ console.log(data); }, error:function(data){ console.log("error:"+data); } }); }, error:function(data){ console.log("error:"+data); } });
