我想通过ftp上传文件。 我发现了一些信息而已，并建立我的课就像我在这里找到：http://www.sebastianviereck.de/ftp-upload-mit-android/Android FTP上传 - 文件未上传
我还添加Internet权限的清单，并设置strictmode像我在这里找到： Error StrictMode$AndroidBlockGuardPolicy.onNetwork
的结果storeFile ist treu并且ftpClient的回复代码为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）”）。
对我来说看起来不错，但文件没有上传。
有人有想法吗？
这里是我的代码：
主营：
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.getReplyString（）的ftpClient.login，this.ftpClient后.changeWorkingDirectory（this.serverDirectory），this.ftpClient.setFileType（2）;
FTP Server Response: 200 Type set to I
和this.ftpClient.storeFile（remoteFileName，buffIn）之后的回复代码;
Reply code: 226
我可以通过Ftp客户端（如FileZilla或Turbo FTP Client）上传文件。 在这里你可以看到我的笔记本电脑上使用的FileZilla的日志。

@ DimaKozhevin这个问题不是重复的。我真的从storeFile功能回来 – Fabian
告诉我们[mcve]。向我们展示'remoteFileName'的实际值。告诉我们如何检查*“文件未上传”*。向我们显示一个日志文件。 –
