无法在实际服务器上写入图像文件

Question

I'm working with android and try to create an app that able to upload several image to the server. I had tried to upload the image to my localhost using xampp, it works well. But when I try to upload to my enterprise server I can't find my file, in the other word. The file can't be written. I don't know what make it failed? This is my code

Upload tp XAMPP

Connection string private static final String url_photo = "http://192.168.7.110/blabla/base.php";

Path static final String path = "C:\\\\xampp\\\\htdocs\\\\psn_asset_oracle\\\\Images\\\\";

Upload to actual enterprise server

Connection String private static final String url_photo = "http://192.168.4.27/oracle/logam/am/data_images/android_image/base.php";

Path static final String path = "http://192.168.4.27/oracle/logam/am/data_images/android_image/";

My code to upload to server

params_p.add(new BasicNameValuePair("image_name_1",
                        image_name_1));
                params_p.add(new BasicNameValuePair("image_name_2",
                        image_name_2));
                params_p.add(new BasicNameValuePair("image_name_3",
                        image_name_3));
                params_p.add(new BasicNameValuePair("image_name_4",
                        image_name_4));
json_photo = jsonParser.makeHttpRequest(url_photo, "POST", params_p);
ArrayList<NameValuePair> params_p = new ArrayList<NameValuePair>();

PHP code

if(isset($_POST["image_name_1"]) && isset($_POST["image_name_2"]) && isset($_POST["image_name_3"]) && isset($_POST["image_name_4"]) 
&& isset($_POST["image_1"]) && isset($_POST["image_2"]) && isset($_POST["image_3"]) && isset($_POST["image_4"]))
{
$image_name_1 = $_POST["image_name_1"];
$image_name_2 = $_POST["image_name_2"];
$image_name_3 = $_POST["image_name_3"];
$image_name_4 = $_POST["image_name_4"];
$image_1 = $_POST["image_1"];
$image_2 = $_POST["image_2"];
$image_3 = $_POST["image_3"];
$image_4 = $_POST["image_4"];

/*---------base64 decoding utf-8 string-----------*/
$binary_1=base64_decode($image_1);
$binary_2=base64_decode($image_2);
$binary_3=base64_decode($image_3);
$binary_4=base64_decode($image_4);

/*-----------set binary, utf-8 bytes----------*/
header('Content-Type: bitmap; charset=utf-8');
/*---------------open specified directory and put image on it------------------*/
$file_1 = fopen($image_name_1, 'wb');
$file_2 = fopen($image_name_2, 'wb');
$file_3 = fopen($image_name_3, 'wb');
$file_4 = fopen($image_name_4, 'wb');

/*---------------------assign image to file system-----------------------------*/
fwrite($file_1, $binary_1);
fclose($file_1);
fwrite($file_2, $binary_2);
fclose($file_2);
fwrite($file_3, $binary_3);
fclose($file_3);
fwrite($file_4, $binary_4);
fclose($file_4);

$response["message"] = "Success";
echo json_encode($response);

}

I've contact my DBA and asked to give me permission to write the file, and it still doesn't work. The error is json doesn't give "Success" as message that indicate the file failed to be written. I will appreciate any help. Thank you.

Answer 1

Does the file server allows write access permission? Sample of chmod, http://catcode.com/teachmod/

Is your enterprise server online? The IP address looks private to me, 192.168.4.27.

Answer 2

Dont use json use http post.

See below code

    HttpClient client = new DefaultHttpClient();
    String postURL = "your url";
    HttpPost post = new HttpPost(postURL);

    try {
        MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);

        ByteArrayBody bab = new ByteArrayBody(img, "image.jpg");
        reqEntity.addPart("image", bab); 
        post.setEntity(reqEntity);
        HttpResponse response = client.execute(post);

Here img is your image in ByteArray format

我的DBA给我另一个文件路径后，问题解决了。
