jQuery简单封装ajax，带logintoken

const URL = 'http://192.168.1.28:8081';
function ajax(params,success){
    let token = sessionStorage.getItem('loginToken');
    params._params.loginToken = token;
    $.ajax({
        type:"post",
        url:URL+'/common/service.execute.json',
        headers:{"Content-Type":"application/x-www-form-urlencoded;charset=UTF-8"},
        data:{
            _call:params.api,
            _params:JSON.stringify(params._params)
        },
        success:success,
        error:function(){
            $.alert("加载失败")
        },
    })
}

let login = {
    api:'sys.memberService.login',
    _params:{
        appId:"6",
        spId:"1",
        loginName:"13438813049",
        loginType:"2",
        validCode:"8888"
    }
};

ajax(login,function success(res){
        let json = eval('(' + res + ')');
        console.log(json)
        sessionStorage.setItem('loginToken',json.output.loginToken);
    }
);
