1、安装插件程序【方正影像采集插件安装包_I_v3.0.74.0.exe】

2、根据技术人员提供的HTMLdemo进行开发

34.jpg

增加摄像预览控件，客户不需要预览，因此我进行了隐藏

增加按钮事件方法，另外由于初始化需要一定的时间，技术人员说是3秒，因此我设置了一个等待3秒再执行拍摄的方法。最后得到图像的Base64字符流传至后台进行上传到服务器

function sleep(numberMillis) {

var now = new Date();

var exitTime = now.getTime() + numberMillis;

while (true) {

now = new Date();

if (now.getTime() > exitTime)

return;

}

}

function onCaptureClick(event) {

var Capture;//必须得获取object对象

var szDeviceIndex = "0";//设备的编号； 0：文档摄像头;1：人像摄像头

var today = new Date();

var month = today.getMonth() + 1;

month = month < 10 ? '0' + month : month;

var day = today.getDate() < 10 ? '0' + today.getDate() : today.getDate();

var hours = today.getHours() < 10 ? '0' + today.getHours() : today.getHours();

var mins = today.getMinutes() < 10 ? '0' + today.getMinutes() : today.getMinutes();

var secs = today.getSeconds() < 10 ? '0' + today.getSeconds() : today.getSeconds();

var imgeId = today.getFullYear() + month + day + hours + mins + secs;

var strFilePath = "D:\\DocImage\\";

var szPostfix = ".jpg";

var result;

//判断是否为ie浏览器

//var IEVersion = IEVersion();

//var isie = isIE();

//if (isie == "1") {

// alert("请切换到IE兼容模式或使用IE浏览器！");

// return;

//}

Capture = document.getElementById("Capture");//根据js的脚本内容，必须先获取object对象

result = Capture.InitDevice();//初始化 0-成功

//alert("初始化：" + result.toString());

result = Capture.StartDevice(szDeviceIndex);//打开文档摄像头 0-成功

//alert("打开摄像头:" + result.toString());

result = Capture.SetResolution(szDeviceIndex, "3742", "2806");//设置分辨率 0-成功

//alert("设置分辨率:" + result.toString());

result = Capture.SetCutPageType(szDeviceIndex, "1");//自动切边 0-成功

//alert("自动切边:" + result.toString());

var strFileName = strFilePath + imgeId.toString() + szPostfix;

//setTimeout(Capture.CaptureImage(szDeviceIndex , strFileName), 3000); //

sleep(3000); //3秒后再进行拍摄 太快 反应不过来

result = Capture.CaptureImage(szDeviceIndex, strFileName); //拍摄 0 - 成功

if (result.toString() != "0") {

alert("拍摄失败！");

return;

}

var strBase64 = Capture.EncodeBase64(strFileName);//获取图像的Base64字符流;

var VoucherCode = F("").getValue(); //出库单号

//上传到服务器

var pars = {

strBase64: strBase64,

VoucherCode: VoucherCode

};

$.ajax({

url: "/Common/commonServices.ashx?Module=OutStockCapture&r=" + Math.random(),

type: 'post',

cache: false,

dataType: 'json',

data: pars,

success: function (data) {

if (data.d.success == 1) {

//刷新附件列表

__doPostBack('', 'btnCaptureClick');

alert("上传成功！");

return;

}

else {

//alert("上传失败！");

return;

}

}

});

//Capture.ReleaseDevice(); //最后释放设备

}

commonServices.ashx 文件上传图片方法

private void OutStockImgUpload(HttpContext context)

{

JObject obj = null;

string ms = "";

//bool result = true;

string VoucherCode = context.Request.Form["VoucherCode"];

string strBase64 = context.Request.Form["strBase64"];

byte[] bt = Convert.FromBase64String(strBase64);//获取图片base64

string fileName = DateTime.Now.ToString("yyyyMMdd");

string imageName = System.DateTime.Now.ToString("yyyyHHddHHmmss");

string ImageFilePath = "/upload" + "/" + fileName;

if (System.IO.Directory.Exists(HttpContext.Current.Server.MapPath(ImageFilePath)) == false)//如果不存在就创建文件夹

{

System.IO.Directory.CreateDirectory(HttpContext.Current.Server.MapPath(ImageFilePath));

}

string ImagePath = HttpContext.Current.Server.MapPath(ImageFilePath) + "/" + imageName;//定义图片名称

File.WriteAllBytes(ImagePath + ".jpg", bt); //保存图片到服务器，然后获取路径

//保存路径

T_Oper_OutStockVoucherService service = new T_Oper_OutStockVoucherService();

T_Annex_OutStockVoucher item = new T_Annex_OutStockVoucher();

item.FilePath = ImageFilePath + "/" + imageName + ".jpg";

item.VoucherCode = VoucherCode;

int result = service.InserOutStockVoucherAnnex(item);

if (result == 1)

{

obj = new JObject(new JProperty("d", new JObject(

new JProperty("msg", ms),

new JProperty("success", "1"))));

context.Response.Write(obj.ToString());

return;

}

else

{

obj = new JObject(new JProperty("d", new JObject(

new JProperty("msg", ms),

new JProperty("success", "0"))));

context.Response.Write(obj.ToString());

return;

}

}
