我正在尝试将存储在手机上的图像上传到linux目录中。代码似乎运行没有错误，并且异常不会捕获任何问题，但图像不会上传。发回HTTP 200 ok响应。通过logcat查看显示的唯一警告是：
Failure getting entry for 0x01080c1 (t=7 e=705) in package 0 (error -75)
我已经确定我在Android清单中使用了互联网权限声明，并且我已将目标文件夹权限设置为777，是否有我错过的内容？
这是android函数：
public int uploadFile(String sourceFileUri) {
String fileName = sourceFileUri;
HttpURLConnection conn = null;
DataOutputStream dos = null;
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1 * 1024 * 1024;
File sourceFile = new File(sourceFileUri);
if (!sourceFile.isFile()) {
dialog.dismiss();
Log.e("uploadFile", "Source File not exist :"
+uploadFilePath + "" + uploadFileName);
runOnUiThread(new Runnable() {
public void run() {
messageText.setText("Source File not exist :"
+uploadFilePath + "" + uploadFileName);
}
});
return 0;
}
else

}
这是PHP脚本
<?php
$file_path = "/var/www/images/";
$file_path = $file_path . basename( $_FILES['uploaded_file']['name']);
if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) {
echo "success";
} else{
echo "fail";
}
?>

试试这可以帮助您
HttpURLConnection mHttpURLConnection = null;

if (sourceFile.isFile()) {
try {
// open a URL connection to the Servlet

if (serverResponseCode == 200) {

}
听到 strUploadFiles 是您的文件路径
您的Serverside代码
<?php
$Dir = "C:/Path/";
if(!is_dir($Dir))
{
mkdir($Dir, 0777);
chmod($Dir, 0777);
}
$file_path = $Dir.basename( $_FILES['uploaded_file']['name']);
?>
