Android FTP上传 - 不上传文件

标签： android ftp apache-commons-net

我想通过ftp上传文件。 我找到了一些关于它的信息并建立了我的课程，就像我在这里找到的那​​样：http://www.sebastianviereck.de/ftp-upload-mit-android/

我还在清单中添加了互联网权限，并设置了严格模式，就像我在这里找到的那​​样： Error StrictMode$AndroidBlockGuardPolicy.onNetwork

storeFile ist treu的结果和ftpClient的回复代码是226（“关闭数据连接。请求的文件操作成功（例如，文件传输或文件中止）”）。

所以它对我来说很好，但文件没有上传。

有人有想法吗？

这是我的代码：

主：

FtpDataHandler ftp = new FtpDataHandler("serverName", "userName", "password", "/folder");
                    ftp.uploadFile("/storage/emulated/0/pictures/test_sig.jpg", "test_sig.jpg");

FTP处理程序：

import java.io.BufferedInputStream;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;

import org.apache.commons.net.ftp.FTPClient;

import android.util.Log;

public class FtpDataHandler {
    private static final String TAG = "FtpDataHandler";

    String serverAdress;
    String userName;
    String password;
    String serverDirectory; 
    FTPClient ftpClient;

    public FtpDataHandler(String serverAdress, String userName, String password, String serverDiretory) {
        this.serverAdress = serverAdress;
        this.userName = userName;
        this.password = password;
        //this was my problem. I set the serverAdress to the serverDirectory insted the serverDirectory
        //this.serverDirectory = serverAdress;
        this.serverDirectory = serverDirectory;

        connect();
    }  

    public String getServerAdress() {
        return serverAdress;
    }

    public String getUserName() {
        return userName;
    }

    public String getServerDirectory() {
        return serverDirectory;
    }

    public boolean uploadFile(String localFilePath, String remoteFileName) {
        boolean result = false;

        BufferedInputStream buffIn = null;
        try {
            buffIn = new BufferedInputStream(new FileInputStream(localFilePath));
        } catch (FileNotFoundException e) {
            Log.d(TAG,
                    "FileNotFoundException: local File to be uploaded not Found: " + localFilePath);
        }
        ftpClient.enterLocalPassiveMode();

        try {
            result = ftpClient.storeFile(remoteFileName, buffIn);
            Log.d(TAG, "Reply code: " + ftpClient.getReplyCode());
        } catch (IOException e) {
            Log.d(TAG, "IOException: remote File could not be accessed");
        }
        try {
            buffIn.close();
        } catch (IOException e) {
            Log.d(TAG, "IOException: buffIn.close()");
        }

        return result;
    }

    public boolean connect(){
        boolean bool = false;
        ftpClient = new FTPClient();

        try {

            ftpClient.connect(this.serverAdress);
            bool = ftpClient.login(this.userName, this.password);
            if (!bool){
                Log.d(TAG, "Login Reply Code" + ftpClient.getReplyCode());
            }
            ftpClient.changeWorkingDirectory(this.serverDirectory);
            ftpClient.setFileType(org.apache.commons.net.ftp.FTP.BINARY_FILE_TYPE);
        } catch (IOException e) {
            Log.d(TAG,
                    "IOException ftp Client could not be established.controll Login, Server, Pw.");
        }
        Log.d(TAG, "FTP Server Response: " + ftpClient.getReplyString());

        return bool;
    }

    public void unregisterConnection(){
        try {
            ftpClient.logout();
            ftpClient.disconnect();
        } catch (IOException e) {
            Log.d(TAG, "IOException: ftpClient close/logout");
        }
    }
}

这里也是ftpClient.login之后的ftpClient.getReplyString（），this.ftpClient.changeWorkingDirectory（this.serverDirectory），this.ftpClient.setFileType（2）; 

FTP Server Response: 200 Type set to I

此后的回复代码.ftpClient.storeFile（remoteFileName，buffIn）; 

Reply code: 226

我可以通过像FileZilla或Turbo FTP Client这样的Ftp客户端上传文件。 在这里，您可以看到我的笔记本电脑上使用的FileZilla日志。

我解决了问题。这是FtpDataHandler中的副本和过去失败。 我将this.serverDirectory设置为等于serverAdress。所以Ftp客户端找不到服务器上的目录。

以下是代码snippit：

public FtpDataHandler(String serverAdress, String userName, String password, String serverDiretory) {
    this.serverAdress = serverAdress;
    this.userName = userName;
    this.password = password;
    //this was my problem. I set the serverAdress to the serverDirectory insted the serverDirectory
    //this.serverDirectory = serverAdress;
    this.serverDirectory = serverDirectory;

    connect();
}

我也在问题中修复了它，以便更容易找到完整的解决方案。
