Question

我正在使用Phonegap创建专门针对Android，Ios和Windows手机的应用。有了这个，我使用Camera API来捕捉手机上的图片。这些目前尚未存储，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（例如以.jpeg格式）。这是通过JavaScript / HTML。如何创建此文件并存储？

var pictureSource; //图片来源 var destinationType; //设置返回值的格式

// 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);
}

你可以获取FILE_URI，然后使用php将其上传到你的服务器，如下所示：

手机密码：

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
        }
            );

PHP代码（upload.php）：

<?php
print_r($_FILES);
$new_image_name = "namethisimage.jpg";
move_uploaded_file($_FILES["file"]["tmp_name"], "/srv/www/upload/".$new_image_name);
?>

如何将捕获的图片存储在我的服务器上
