我尝试从图库中获取图片,并使用钛金属网络服务将所选图片上传到服务器。
我使用了下面的代码。但是我收到了调试错误:HTTP错误并且它还显示警告框,例如"连接期间出现错误"
此代码在我的开发服务器中正常运行。但它无法在我的客户端服务器中运行。原因是什么?为什么我的代码无法在我的客户端服务器上运行?
从Android设备上传文件时文件上传工作正常。但是从iphone设备上传文件时它无法正常工作。您能否给我一个解决此问题的建议?
为什么我的控制台窗口出现此错误。
function AUF_ADD_File_FolderData () {
Titanium.Media.openPhotoGallery({
success:function(event) {
var request = Ti.Network.createHTTPClient({
onload : function(e) {
Ti.API.info(this.responseText);
Ti.API.info("image pathe"+" "+event.media);
if(this.responseText == "Successfully file is created"){
var managefolders =Alloy.createController('manage_folders').getView();
managefolders.open();
}
else{
alert(this.responseText);
}
},
onerror: function(e){
Ti.API.debug(e.error);
alert("There was an error during the connection");
},
timeout:20000,
});
var uploadabc = event.media.imageAsResized(400 , 400);
request.open("POST",url+"client/manager/at_manager_create_common_file.php");
var params = ({"manager_id": manager_id,"file": uploadabc,});
// var params = ({"manager_id": manager_id,"file": event.media,});
request.send(params);
},
cancel:function() {
// called when user cancels taking a picture
},
error:function(error) {
// called when there's an error
var a = Titanium.UI.createAlertDialog({title:'Camera'});
if (error.code == Titanium.Media.NO_CAMERA) {
a.setMessage('Please run this test on device');
} else {
a.setMessage('Unexpected error: ' + error.code);
}
a.show();
},
saveToPhotoGallery:false,
// allowEditing and mediaTypes are iOS-only settings
allowEditing:true,
mediaTypes:[Ti.Media.MEDIA_TYPE_VIDEO,Ti.Media.MEDIA_TYPE_PHOTO]
});
}
修改
这是php文件:
<?php
$request = base64_decode($_POST['jsondata']);
$data = json_decode($request,true);
$manager_id = $data['manager_id'];
$file_name = $data['file_name'];
$source = base64_decode($data['source']);
include "db_connect.php";
// connecting to db
$db = new DB_CONNECT();
$result = mysql_query("SELECT * from at_common_files WHERE user_id = '$manager_id' and file_name = '$file_name'");
$no_of_rows = mysql_num_rows($result);
if ($no_of_rows > 0) {
$response='{"Error":"1","Message":"Filename already existed"}';
echo $response;
} else {
$upload_dir = 'common_files/'.$manager_id."_".$file_name;
file_put_contents($upload_dir,$source);
$qugery = mysql_query("insert into at_common_files (user_id,file_name) values ($manager_id, '$file_name') ");
$response = '{"Error":"0","Message":"Successfully file is created"}';
echo $response;
}
?>
修改
我收到以下错误:
:[DEBUG] HTTP错误 :[信息]错误{&#34;输入&#34;:&#34;错误&#34;,&#34;来源&#34;:{&#34;缓存&#34;:false}, &#34;代码&#34;:404,&#34;错误&#34;:&#34; HTTP错误&#34;,&#34;成功&#34;:false}
如果我已经调用相同的url并单独传递manager_id,那么结果很好。如果我已经传递了manager_id和文件,这次只会得到Http错误。我无法找到确切的问题。因为相同的钛代码和PHP代码(开发服务器)工作正常,图像上传到开发服务器文件夹。但我已将相同的php文件移动到我的客户端server.now它无法正常工作。同样的网络服务网址在浏览器中工作正常,而android.it只能在iphone中工作。那么我究竟无法找到问题所在?能不能给我一个解决方案。

我面临着一个完全相同的问题。请你给我一个解决方案。

我发现了很多像这样的问题(例如The 'Passive' connection '<appname>' access to protected services is denied)。
答案总是:
&#34;这个错误被称为&#34; Red Herring&#34;。这是一个令人误解的线索。 HID不是影响您的应用的真正错误。应该有其他消息可以指示发生了什么。&#34;
所以看看是否有其他错误massege描述了你的问题。
$file_name = mysql_real_escape_string($data['file_name']);

确保您的设备已连接到互联网,然后按以下方式尝试:
钛:
function AUF_ADD_File_FolderData () {
Titanium.Media.openPhotoGallery({
success:function(event) {
var xhr = Titanium.Network.createHTTPClient();
xhr.onerror = function(e){
Ti.API.info('IN ERROR ' + JSON.stringify(e));
alert('Sorry, we could not upload your photo! Please try again.');
};
xhr.onload = function(){
Ti.API.info(this.responseText);
Ti.API.info("image pathe"+" "+event.media);
if(this.responseText == "Successfully file is created"){
var managefolders =Alloy.createController('manage_folders').getView();
managefolders.open();
}else{
alert(this.responseText);
}
};
xhr.open('POST', url+"client/manager/at_manager_create_common_file.php");
xhr.send({
media: event.media,
manager_id: manager_id
});
},
cancel:function() {
// called when user cancels taking a picture
},
error:function(error) {
// called when there's an error
var a = Titanium.UI.createAlertDialog({title:'Camera'});
if (error.code == Titanium.Media.NO_CAMERA) {
a.setMessage('Please run this test on device');
} else {
a.setMessage('Unexpected error: ' + error.code);
}
a.show();
},
saveToPhotoGallery:false,
// allowEditing and mediaTypes are iOS-only settings
allowEditing:true,
mediaTypes:[Ti.Media.MEDIA_TYPE_VIDEO,Ti.Media.MEDIA_TYPE_PHOTO]*/
});
}
PHP:
<?php
//this function returns a random 5-char filename with the jpg extension
function randomFileName()
{
$length = 5;
$characters = 'abcdefghijklmnopqrstuvwxyz';
$string = '';
for ($p = 0; $p < $length; $p++) {
$string .= $characters[mt_rand(0, strlen($characters))];
}
return $string . '.jpg';
}
//create the random filename string and uploads target variables
$randomString = randomFileName();
$target = 'common_files/'.$randomString;
if(move_uploaded_file($_FILES['media']['tmp_name'], $target))
{
echo "success";
}
else
{
echo "moving to target failed";
}
?>

如果它像这样工作,你将不得不再次添加你的逻辑(resizing和manager_id)
