Cordova - 从相册中选择照片并上传,以及拍照上传
1,安装需要的插件
2,选择设备照片并上传
3,拍照并上传
下面代码样例,当点击按钮后会掉用摄像头拍照,并在页面上显示出来。同时拍摄照片会上传到服务器上。
不管是从相册中选择图片上传,还是拍照上传。我们都需要如下先安装如下三个插件:Camera(相机)、file(文件访问操作)、fileTransfer(文件传输)。
如果没有安装的话,先安装下:
cordova plugin add cordova-plugin-camera cordova plugin add cordova-plugin-file cordova plugin add cordova-plugin-file-transfer
2,选择设备照片并上传
下面代码样例,点击按钮后会打开系统相册来选择照片,选中的照片会显示在页面上。同时会把选择的照片上传到服务器。
注意:camera 插件除了可以选择图片外,也可以选择视频。如果需要实现选择视频功能,我们只要在 getPicture 方法最后一个参数对象中添加 mediaType:navigator.camera.MediaType.VIDEO 配置即可。

附:服务端代码(upload.php)
<? $value1 = $_POST["value1"]; $value2 = $_POST["value2"]; move_uploaded_file($_FILES["file1"]["tmp_name"], $_SERVER["DOCUMENT_ROOT"]."/upload/" . $_FILES["file1"]["name"]); echo "服务器收到如下数据:\r"; echo $value1."\r"; echo $value2."\r"; echo $_FILES["file1"]["name"]."\r"; ?>
你好想請問一下 error.code = 3 3的錯誤訊息要在哪邊查詢
我php端的設定
<?php
header("Content-Type: text/html; charset=utf-8");
header('Access-Control-Allow-Origin:*');
header('Access-Control-Allow-Methods: GET, POST, PUT, DELETE, OPTIONS');
header('Access-Control-Allow-Headers: X-Requested-With, Content-Type, Accept');
$new_image_name = strtolower($_FILES['file']['name']);
move_uploaded_file($_FILES["file"]["tmp_name"], "uploadFiles/".$new_image_name);
?>
不太會部屬php端 可否給個提示
