Question

Good Day，我该如何计算要在Postman上进行路由和检查的公共功能？这是我的密码

for innerDict in dict.values {
    if let value = innerDict["code"] {
        print("value is: \(value)")
    }
}

我希望Diff能够在Postman上发布这是我的代码的App.js。我怎样才能从mysql查询中调用数据到函数并在路由器上返回计算的数据或者你们可以为此提供正确的术语。

router.post('/post_regular_hours/:employee_id/',function(request,response,next){
    var id = request.params.employee_id;
    var time_in = request.params.time_in;
    var time_out = request.params.time_out;
    // const timein = request.params.time_in;
    // const timeout = request.params.time_out;
    knexDb.select('*')
            .from('employee_attendance')
            .where('employee_id',id)
            .then(function(result){

                res.send(compute_normal_hours(response,result,diff))


            })
});

function compute_normal_hours(res,result,diff){

    let time_in = moment(time_in);
    let time_out = moment(time_out);


    let diff = time_out.diff(time_in, 'hours');



    return diff;

}

您的代码有一些问题。请参阅相应代码块中的说明。

router.post('/post_regular_hours/:employee_id/',function(request,response,next){

    // If you're receiving a post request
    // you'll probably want to check the body for these parameters.
    let id = request.params.employee_id; // make sure the param names are matching with what you post.
    // This one is special because you are passing it through the url directly
    let time_in = request.body.time_in;
    let time_out = request.body.time_out;        

    knexDb.select('*')
            .from('employee_attendance')
            .where('employee_id',id)
            .then(function(result){

                // you are not sending time_in and time_out here - but difference. but difference is not calculated.
                // changed the function signature a bit - you weren't using the result at all? leaving this callback here because I'm sure you want to map the used time to some user?
                return response.send(compute_normal_hours(time_in, time_out))
            });
});

// this function was (and still might be) incorrect.
// You were passing res and result which neither of them you were using.
// You also had time_in and time_out which were going to be undefined in the function scope. Now that we are passing them in it should be ok. Updated it so you don't have the params you don't need.

function compute_normal_hours(time_in, time_out){
    // What was diff - if it's the time difference name things correctly
    // You had a diff parameter passed in (which you didn't compute), a diff function called below and another variable declaration called diff.
    // you were not passing time_in or time_out parameters.
    // you have moment here - are you using a library?
    let time_in = moment(time_in);
    let time_out = moment(time_out);

    let diff = time_out.diff(time_in, 'hours');

    return `Computed result is: ${diff}`;    
}

重要修改

请搜索所有出现的res.render（response.render）并替换为res.send之类的东西-res.render正在寻找模板引擎

NodeJS到邮递员的结果
