Question

我试图研究和阅读很多关于这个问题的文章

我有一些红色，但讨论似乎在没有解决方案的情况下结束

所以问题是我无法在我的CI应用程序上显示相机，但是当我只是复制确切的代码并将其粘贴到我的localhost而不使用任何框架工作时它会起作用。

这是我的CI代码

    <script type="text/javascript" src="<?=base_url('assets/js/cam/webcam.js')?>"></script>
        <script language="JavaScript">
                document.write( webcam.get_html(440, 240) );
        </script>
        <form>
        <br />

            <input type=button value="Configure settings" onClick="webcam.configure()" class="shiva">
            &nbsp;&nbsp;
            <input type=button value="snap" onClick="take_snapshot()" class="shiva">
        </form>


<script  type="text/javascript">
    webcam.set_api_url( "<?=base_url('assets/js/cam/handleimage.php')?>");
        webcam.set_quality( 90 ); // JPEG quality (1 - 100)
        webcam.set_shutter_sound( true, "<?=base_url('assets/js/cam/shutter.mp3')?>" ); // play shutter click sound
        webcam.set_hook( 'onComplete', 'my_completion_handler' );
        function take_snapshot(){
            // take snapshot and upload to server
            document.getElementById('img').innerHTML = '<h1>Uploading...</h1>';

            webcam.snap();
        }

        function my_completion_handler(msg) {
            // extract URL out of PHP output
            if (msg.match(/(http\:\/\/\S+)/)) {
                // show JPEG image in page

                document.getElementById('img').innerHTML ='<h3>Upload Successfuly done</h3>'+msg;

                document.getElementById('img').innerHTML ="<img src="+msg+" class=\"img\">";


                // reset camera for another shot
                webcam.reset();
            }
            else {alert("Error occured we are trying to fix now: " + msg); }
        }
    </script>

我使用了这个演示包，如果我将它解压缩到localhost，它的工作正常。 https://app.box.com/s/nkhgrj73fvutaj6dfspf

但是当我尝试将它集成到CI时，相机窗口显示为空白。当我尝试使用网络摄像头js功能，如webcam.configure（）..它说电影尚未加载

只需复制粘贴即可在codeigniter上实现。错误It says the Movie is not loaded yet背后的原因webcam.swf未加载。实际上flash文件是网络摄像头功能背后的重要内容。

创建新控制器application\controllers\camera.php

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

    class Camera extends CI_Controller {

        public function index(){
            $this->load->helper('url');
            $this->load->view("camera");

        }


        public function saveImage(){

            /*write your own code to save to your database*/        
            $newname = "some_name.png"; 
            file_put_contents( $newname, file_get_contents('php://input') );

        }
    }

?>

创建新视图application\views\camera.php

    </div>
</body>

</html>

现在将webcam.js,shutter.mp3,webcam.swf复制到assets/js/cam。在webcam.js

中进行2次小的更改

第27行：swf_url：＆＃39; webcam.swf＆＃39;

第28行：shutter_url：＆＃39; shutter.mp3＆＃39;

更改为

第27行：swf_url：＆＃39; assets / js / cam / webcam.swf＆＃39;

第28行：shutter_url：＆＃39; assets / js / cam / shutter.mp3＆＃39;

来自Tintu先生答案增加了一些修订

            function my_completion_handler(msg) {
                if (msg.match(/(http\:\/\/\S+)/)) {
                    document.getElementById('img').innerHTML = '<h3>Upload Successfuly done</h3>' + msg;

                    document.getElementById('img').innerHTML = "<img src=" + msg + " class=\"img\">";
                    webcam.reset();
                } else {
                    alert("Error occured we are trying to fix now: " + msg);

        </div>
    </div>
</body>

</html>

现在将webcam.js，shutter.mp3，webcam.swf复制到assets / js / cam。在webcam.js中进行2次小改动

line number 27 : swf_url: 'webcam.swf'

line number 28 : shutter_url: 'shutter.mp3'

更改为

line number 27 : swf_url: '../assets/js/cam/webcam.swf'

line number 28 : shutter_url: '../assets/js/cam/shutter.mp3'

注意：这个网址很重要并且会有所不同..根据我的经验，最好通过谷歌浏览器检查.swf url exstince而不是firefox ..添加'../'上传一个文件夹让你进入root app文件夹访问资产文件夹
