工作笔记5

1、js 时间转化为几天前、几小时前、几分钟前

function getDateDiff(dateTimeStamp){
    var minute = 1000 * 60;
    var hour = minute * 60;
    var day = hour * 24;
    var halfamonth = day * 15;
    var month = day * 30;
    var now = new Date().getTime();
    var diffValue = now - dateTimeStamp;
    if(diffValue < 0){return;}
    var monthC =diffValue/month;
    var weekC =diffValue/(7*day);
    var dayC =diffValue/day;
    var hourC =diffValue/hour;
    var minC =diffValue/minute;
    if(monthC>=1){
        result="" + parseInt(monthC) + "月前";
    }
    else if(weekC>=1){
        result="" + parseInt(weekC) + "周前";
    }
    else if(dayC>=1){
        result=""+ parseInt(dayC) +"天前";
    }
    else if(hourC>=1){
        result=""+ parseInt(hourC) +"小时前";
    }
    else if(minC>=1){
        result=""+ parseInt(minC) +"分钟前";
    }else
    result="刚刚";
    return result;
}

   C# 时间转化为几天前、几小时前、几分钟前

    private string GetDateDiff(int dateTimeStamp) {
        string result = string.Empty;
        var minute = 60;
        var hour = minute * 60;
        var day = hour * 24;
        var halfamonth = day * 15;
        var month = day * 30;
        var now = GetTimeStamp();
        var diffValue = now - dateTimeStamp;
        if (diffValue < 0) { return ""; }
        var monthC = diffValue / month;
        var weekC = diffValue / (7 * day);
        var dayC = diffValue / day;
        var hourC = diffValue / hour;
        var minC = diffValue / minute;
        if (monthC >= 1) {
            result = "" + Convert.ToInt32(monthC) + "月前";
        } else if (weekC >= 1) {
            result = "" + Convert.ToInt32(weekC) + "周前";
        } else if (dayC >= 1) {
            result = "" + Convert.ToInt32(dayC) + "天前";
        } else if (hourC >= 1) {
            result = "" + Convert.ToInt32(hourC) + "小时前";
        } else if (minC >= 1) {
            result = "" + Convert.ToInt32(minC) + "分钟前";
        } else {
            result = "刚刚";
        }
        return result;
    }

    public Int64 GetTimeStamp() {
        TimeSpan ts = DateTime.Now - new DateTime(1970, 1, 1, 0, 0, 0, 0);
　　　　 //去掉毫秒数
        var time = ts.TotalMilliseconds.ToString().Substring(0, 10);
        return Convert.ToInt64(time);
    }

 2、C#  把时间戳转化成日期

private DateTime GetTime(string timeStamp) {
        DateTime dtStart = new DateTime(1970, 1, 1);
        long lTime = long.Parse(timeStamp + "0000000");
        TimeSpan toNow = new TimeSpan(lTime);
        return dtStart.Add(toNow);
    }

      js 将从后台得到的时间戳（毫秒数）转换为日期格式

function getDate(time) {
            var unixTimestamp = new Date(time * 1000);
            commonTime = unixTimestamp.getFullYear() + "-" + (unixTimestamp.getMonth() + 1) + "-" + unixTimestamp.getDate() + " " + unixTimestamp.getHours() + ":" + unixTimestamp.getMinutes() + ":" + unixTimestamp.getSeconds();
            alert(commonTime);
        }

 3、js 清除iframe父级的Cookie

function delCookie(time) {
        var myDate = new Date();
        myDate.setTime(-1000);//设置时间    
        parent.document.cookie = time + "=;expires=" + myDate.toGMTString();

        //document.cookie = time + "=;expires=" + myDate.toGMTString();

}

 4、return false 阻止a标签跳转，但是有target标签的话就无法阻止a跳转了

<a href="javascript:void(0)" onclick="return checkData()">content</a>
<a href="javascript:void(0)" target="_blank" onclick="return checkData()">content</a>

5、设置表格table边框样式

table {
        width:100%;
        border:solid #ccc; border-width:1px 0px 0px 1px;
    }

 6、华硕A84S笔记本安装win7系统时，选择Bios才能安装成功。

 7、数据库tinyint类型的数据，对应C#的byte类型，在使用lamda表达式时不能使用sum函数求和

 8、Fiddler模拟post请求时Header需要增加Content-Type，格式有四种：分别是application/x-www-form-urlencoded（这也是默认格式）、application/json、text/xml以及multipart/form-data格式

 9、调试CC系统操作：

　　　　a、infoservice.dll地址用物理路径写死，如：D:\Codes\CC\Branches\电子发票\WebPublish\CCWEBPUBLISH\WebPublish\bin\32\infoservice.dll

　　　　b、不用添加环境变量；不用把dll拷贝到system32和system64文件夹中

10、捕获EntityFramework报错的具体信息：

　　　　　　　catch (DbEntityValidationException dbEx)
            {
                foreach (var validationErrors in dbEx.EntityValidationErrors)
                {
                    foreach (var validationError in validationErrors.ValidationErrors)
                    {

                        msg = string.Format("Class: {0}, Property: {1}, Error: {2}", validationErrors.Entry.Entity.GetType().FullName,
                            validationError.PropertyName,
                            validationError.ErrorMessage) + "/r/n";
                    }
                }
            }
            catch (Exception ex)
            {
                msg += ex.Message;
            }

 11、VS2017执行单元测试，nuget 安装XUnit 2.2.0、xunit.runner.visualstudio 2.2.0、Moq 4.7.10。

        [Fact]
        public static void GeneratorModelForSqlServer()
        {
            var serviceProvider = BuildServiceForSqlServer();
            var codeGenerator = serviceProvider.GetRequiredService<CodeGenerator>();
            codeGenerator.GenerateModelCodesFromDatabase();
            Assert.Equal(0, 0);
        }

 12、Nuget打包步骤：

　　Nuget打包：ide中类库右键打包（注意项目debug或者release设置，变更同时需修改版本号）

　　nuget.exe下载： 99.48.212.228开发软件C Sharp

　　上传至nuget步骤：

　　拷贝nuget.exe至*.nupkg所在目录

　　执行命令nuget.exe push {package file} {apikey} -Source http://nuget/nuget

　　如：nuget.exe push Joying.Framework.EBoxClient.1.0.0.nupkg 123abc -Source http://99.48.212.10/nuget

13、使用EF生成数据库实体模型，采用DBFirst的命令：

　　Scaffold-DbContext "Data Source=.;Initial Catalog=EvaluationDB;User ID=sa;Password=123456;Integrated Security=False;" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models
