aes加解密前后端-前端

一、ajax请求前端

f12请求和响应参数效果：

1、在前端封装ajax的公共Util的js中，封装ajax请求的地方，在beforeSend方法和成功之后的回调函数success方法中：

var param;
            if(GLOBAL_CONFIG.aesOpen=='1'){ //GLOBAL_CONFIG.aesOpen=='1' 是读取项目工程中的一个配置文件中的一个参数，作用是加密和不做加密操作的开关；
                var p=self.param||{};
                var rsaStr=FWRSAHelper.encrypt(self.param); //将请求的参数进行RSA加密操作
                if(self.contentType=='application/json'){ //请求类型有三个，判断是不是json类型，决定是否需要json格式化
                    param=JSON.stringify({p:encrypt(rsaStr,GLOBAL_CONFIG.aecKey)}); //将请求的参数进行aes加密
                }else{
                    param={p:encrypt(rsaStr,GLOBAL_CONFIG.aecKey)};
                }
            }else{
                param=self.param;
            }

$.ajax({
                type: self.type,
                url: self.url,
                contentType: self.contentType,
                data: param,
                async:self.async,
                dataType: self.dataType,
                beforeSend: function(request) {
                    if(GLOBAL_CONFIG.aesOpen=='1'){
                        request.setRequestHeader("token", 'encryption'); //设置请求头一个参数，告诉后台这个请求要进行加解密操作
                    }
                    self.showLoader();
                },
                success: function(result){
                    self.hideLoader();
                    var res;
                    if(GLOBAL_CONFIG.aesOpen=='1'){
                        var jsonStr=decrypt(result.data,GLOBAL_CONFIG.aecKey); //返回的数据进行解密操作，页面获取展示为正常信息，但是开发者工具的f12查看接口的请求和响应参数都是加密过的
                        res=JSON.parse(jsonStr);
                    }else{
                        res=result;
                    }

/**
 * 加密（需要先加载lib/aes/aes.min.js文件）
 * @param word
 * @returns {*}
 */
function encrypt(word,key){
    var key = CryptoJS.enc.Utf8.parse(key);
    var srcs = CryptoJS.enc.Utf8.parse(word);
    var encrypted = CryptoJS.AES.encrypt(srcs, key, {mode:CryptoJS.mode.ECB,padding: CryptoJS.pad.Pkcs7});
    return encrypted.toString();
}

/**
 * 解密
 * @param word
 * @returns {*}
 */
function decrypt(word,key){
    var key = CryptoJS.enc.Utf8.parse(key);
    var decrypt = CryptoJS.AES.decrypt(word, key, {mode:CryptoJS.mode.ECB,padding: CryptoJS.pad.Pkcs7});
    return CryptoJS.enc.Utf8.stringify(decrypt).toString();
}
