javascript - 如何将捕获的图片存储在我的服务器上
<p><p>我正在使用 Phonegap 创建一个专门用于 Android、Ios 和 Windows 手机的应用程序。有了这个,我正在使用相机 API 来捕捉你手机上的图片。这些当前未存储,将在重新打开时删除。因此,我想访问我的服务器来存储图片(例如 .jpeg 格式)。这通过 JavaScript/HTML。我怎样才能创建这个文件并存储它?</p>
<p>var 图片来源;//图片来源
变量目的地类型;//设置返回值的格式</p>
<pre><code>// Wait for device API libraries to load
//
document.addEventListener("deviceready",onDeviceReady,false);
// device APIs are available
//
function onDeviceReady() {
pictureSource=navigator.camera.PictureSourceType;
destinationType=navigator.camera.DestinationType;
}
// Called when a photo is successfully retrieved
//
function onPhotoDataSuccess(imageData) {
// Uncomment to view the base64-encoded image data
// console.log(imageData);
// Get image handle
//
var smallImage = document.getElementById('smallImage');
// Unhide image elements
//
smallImage.style.display = 'block';
// Show the captured photo
// The in-line CSS rules are used to resize the image
//
smallImage.src = "data:image/jpeg;base64," + imageData;
}
// Called when a photo is successfully retrieved
//
function onPhotoURISuccess(imageURI) {
// Uncomment to view the image file URI
// console.log(imageURI);
// Get image handle
//
var largeImage = document.getElementById('largeImage');
// Unhide image elements
//
largeImage.style.display = 'block';
// Show the captured photo
// The in-line CSS rules are used to resize the image
//
largeImage.src = imageURI;
}
// A button will call this function
//
function capturePhoto() {
// Take picture using device camera and retrieve image as base64-encoded string
navigator.camera.getPicture(onPhotoDataSuccess, onFail, { quality: 50,
destinationType: destinationType.DATA_URL });
}
// A button will call this function
//
function capturePhotoEdit() {
// Take picture using device camera, allow edit, and retrieve image as base64-encoded string
navigator.camera.getPicture(onPhotoDataSuccess, onFail, { quality: 20, allowEdit: true,
destinationType: destinationType.DATA_URL });
}
// A button will call this function
//
function getPhoto(source) {
// Retrieve image file location from specified source
navigator.camera.getPicture(onPhotoURISuccess, onFail, { quality: 50,
destinationType: destinationType.FILE_URI,
sourceType: source });
}
// Called if something bad happens.
//
function onFail(message) {
alert('Failed because: ' + message);
}

<p><p>您可以获取 FILE_URI,然后使用 php 将其上传到您的服务器,如下所示:</p>
<p><strong>电话号码:</strong></p>
<pre><code>function uploadPhoto(imageURI) {
var options = new FileUploadOptions();
options.fileKey="file";
options.fileName=imageURI.substr(imageURI.lastIndexOf('/')+1);
options.mimeType="image/jpeg";
var params = new Object();
params.value1 = "test";
params.value2 = "param";
options.params = params;
options.chunkedMode = false;
var ft = new FileTransfer();
ft.upload(imageURI, "http://yourdomain.com/upload.php", win, fail, options);
}
navigator.camera.getPicture(uploadPhoto, function(message) {
alert('get picture failed');
},{
quality: 50,
destinationType: navigator.camera.DestinationType.FILE_URI,
sourceType: navigator.camera.PictureSourceType.PHOTOLIBRARY
}
);
</code></pre>
<p><strong>PHP 代码(upload.php):</strong></p>
<pre><code><?php
print_r($_FILES);
$new_image_name = "namethisimage.jpg";
move_uploaded_file($_FILES["file"]["tmp_name"], "/srv/www/upload/".$new_image_name);
?>
</code></pre></p>
