我是新来的,上周有一个问题:
我在 phonegap(cordova2.1.0) 中制作了一个应用程序,代码如下:
<script type="text/javascript" charset="utf-8">
var deviceReady = false;
/**
* Take picture with camera
*/
function takePicture() {
navigator.camera.getPicture(
function(uri) {
var img = document.getElementById('camera_image');
img.style.visibility = "visible";
img.style.display = "block";
img.src = uri;
document.getElementById('camera_status').innerHTML = "Success";
},
function(e) {
console.log("Error getting picture: " + e);
document.getElementById('camera_status').innerHTML = "Error getting picture.";
},
{ quality: 50, destinationType: navigator.camera.DestinationType.FILE_URI});
};
/**
* Select picture from library
*/
function selectPicture() {
navigator.camera.getPicture(
function(uri) {
var img = document.getElementById('camera_image');
img.style.visibility = "visible";
img.style.display = "block";
img.src = uri;
document.getElementById('camera_status').innerHTML = "Success";
},
function(e) {
console.log("Error getting picture: " + e);
document.getElementById('camera_status').innerHTML = "Error getting picture.";
},
{ quality: 50, destinationType: navigator.camera.DestinationType.FILE_URI, sourceType: navigator.camera.PictureSourceType.PHOTOLIBRARY});
};
/**
* Upload current picture
*/
function uploadPicture() {
// Get URI of picture to upload
var img = document.getElementById('camera_image');
var imageURI = img.src;
if (!imageURI || (img.style.display == "none")) {
document.getElementById('camera_status').innerHTML = "Take picture or select picture from library first.";
return;
}
// Verify server has been entered
server = document.getElementById('serverUrl').value;
if (server) {
// Specify transfer options
var options = new FileUploadOptions();
options.fileKey="file";
options.fileName=imageURI.substr(imageURI.lastIndexOf('/')+1);
options.mimeType="image/jpeg";
options.chunkedMode = false;
// Transfer picture to server
var ft = new FileTransfer();
ft.upload(imageURI, server, function(r) {
document.getElementById('camera_status').innerHTML = "Upload successful: "+r.bytesSent+" bytes uploaded.";
}, function(error) {
document.getElementById('camera_status').innerHTML = "Upload failed: Code = "+error.code;
}, options);
}
}
/**
* View pictures uploaded to the server
*/
function viewUploadedPictures() {
// Get server URL
server = document.getElementById('serverUrl').value;
if (server) {
// Get HTML that lists all pictures on server using XHR
var xmlhttp = new XMLHttpRequest();
// Callback function when XMLHttpRequest is ready
xmlhttp.onreadystatechange=function(){
if(xmlhttp.readyState === 4){
// HTML is returned, which has pictures to display
if (xmlhttp.status === 200) {
document.getElementById('server_images').innerHTML = xmlhttp.responseText;
}
// If error
else {
document.getElementById('server_images').innerHTML = "Error retrieving pictures from server.";
}
}
};
xmlhttp.open("GET", server , true);
xmlhttp.send();
}
}
/**
* Function called when page has finished loading.
*/
function init() {
document.addEventListener("deviceready", function() {deviceReady = true;}, false);
window.setTimeout(function() {
if (!deviceReady) {
alert("Error: PhoneGap did not initialize. Demo will not run correctly.");
}
},2000);
}
HTML 代码:
图片:
<input type="button" onclick="takePicture();" value="Take Picture" /><br/>
<input type="button" onclick="selectPicture();" value="Select Picture from Library" /><br/>
<input type="button" onclick="uploadPicture();" value="Upload Picture" />
</div>
<br/>
好吧:这段代码的一部分不是我的。
问题
没有错误警报
警报说一切都已完成。图片上传和字节
在我的 msql 中,图像没有扩展名(.jpg)只有名称
在图像文件夹中没有上传任何内容
我把所有东西都列入白名单,
有人可以帮助我吗?我不知道还能做什么。。
提前致谢
顺便说一句,在 Eclipse 日志中,一切都显示正常,在 android 2.3 实际手机中也是一样,但图像不存在..
