[英]Can't write image file on actual server
我正在使用android,並嘗試創建一個能夠將多個圖片上傳到服務器的應用。 我曾嘗試使用xampp將圖像上傳到本地主機,效果很好。 但是,換句話說,當我嘗試上傳到企業服務器時,找不到我的文件。 該文件無法寫入。 我不知道是什么使它失敗了? 這是我的代碼
上傳tp XAMPP
連接字符串private static final String url_photo = "http://192.168.7.110/blabla/base.php";
路徑static final String path = "C:\\\\xampp\\\\htdocs\\\\psn_asset_oracle\\\\Images\\\\";
上傳到實際的企業服務器
連接字符串private static final String url_photo = "http://192.168.4.27/oracle/logam/am/data_images/android_image/base.php";
路徑static final String path = "http://192.168.4.27/oracle/logam/am/data_images/android_image/";
我的代碼上傳到服務器
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代碼
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);
}
我已經聯系我的DBA,並要求授予我寫入文件的權限,但該文件仍然無法正常工作。 錯誤是json沒有給出“成功”作為消息,指示文件寫入失敗。 我將不勝感激。 謝謝。
文件服務器是否允許寫訪問權限? chmod示例, http://catcode.com/teachmod/
您的企業服務器是否在線? IP地址對我來說是私有的,192.168.4.27。
不要使用json使用http發布。
見下面的代碼
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);
這是您的ByteArray格式圖像
我的DBA給我另一個文件路徑后,問題解決了。
