我正在开发一个Android应用程序，它可以将图片发送到远程服务器，但是我得到了错误。
错误是，

php代码是，
$target_path1 = "images/uploads/";
$target_path1 = $target_path1 . basename( $_FILES['uploaded_file']['name']);
if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $target_path1)) {
echo "The first file ". basename( $_FILES['uploaded_file']['name']).
" has been uploaded.";
} else{
echo "There was an error uploading the file, please try again!";
echo "filename: " . basename( $_FILES['uploaded_file']['name']);
echo "target_path: " .$target_path1;
}
上述代码有什么问题？
答案 0 :(得分：0)
要存储图像，您可以通过添加以下行将其转换为base64格式：
String strData = Base64.encodeToString(data, Base64.DEFAULT);
entity.addPart("file", strData);
对于PHP方面，您可以执行以下操作：
$fp = fopen( $output_file, "wb" );
fwrite( $fp, base64_decode( $strData) );
fclose( $fp );
其中$ strData是base64编码的字符串
