Java FTP xls文件上传

发布于 2024-12-04 13:35:25 字数 562 浏览 1 评论 0原文

我正在尝试将文件上传到 Java 类中的 FTP 服务器。我使用 apache 库：org.apache.commons.net.ftp.FTPClient。上传功能工作正常，直到我尝试上传 XLS (Excel) 文件。特别是，当我上传时，文件已上传，但似乎已损坏。事实上，它的大小与原始大小不同，当我尝试打开它时，它无法正确打开并且不显示所有数据。

这是我使用的代码的一部分：

FTPClient ftpClient = new FTPClient();
File[] fileList;fileList = localFilePath.listFiles();
for (File file : fileList) {
    String fileName = file.getName();
    FileInputStream fileInputStream = new FileInputStream(file);
    ftpClient.storeFile(fileName, fileInputStream);
    fileInputStream.close();
}

非常感谢您的任何帮助。

I am trying to upload files to a FTP Server in a Java class.
I use apache library: org.apache.commons.net.ftp.FTPClient.
The upload function works fine until I try to upload a XLS (Excel) file.
In particular, when I upload it, the file is uploaded, but it seems to be corrupted. In fact its size is different from the original size and when I try to open it, it doesn't open correctly and doesn't show all the data.

Here is a portion from the code I use:

FTPClient ftpClient = new FTPClient();
File[] fileList;fileList = localFilePath.listFiles();
for (File file : fileList) {
    String fileName = file.getName();
    FileInputStream fileInputStream = new FileInputStream(file);
    ftpClient.storeFile(fileName, fileInputStream);
    fileInputStream.close();
}

Thank you very much for any kind of help.

我使用此线程中的建议解决了问题：

Transfer raw binary with apache commons-net FTPClient？

我所需要做的就是为非 .txt 文件设置二进制文件模式：

if (fileExtension.equals("txt")) {
    ftpClient.setFileType(FTPClient.ASCII_FILE_TYPE);
} else {
    ftpClient.setFileType(FTPClient.BINARY_FILE_TYPE);
}

I solved the problem using the suggestion in this thread:

Transfer raw binary with apache commons-net FTPClient?

All I needed to do was setting binary file mode for non .txt files:

if (fileExtension.equals("txt")) {
    ftpClient.setFileType(FTPClient.ASCII_FILE_TYPE);
} else {
    ftpClient.setFileType(FTPClient.BINARY_FILE_TYPE);
}
