java - 如何使用HttpClient将文件上传到Ubuntu的特定路径

Question

我在将文件上传到我的 Ubuntu 服务器时收到 404 错误。

public class Test {

    public static void main(String[] args) throws ClientProtocolException, IOException {
        // TODO Auto-generated \ stub

        CloseableHttpClient httpClient = HttpClients.createDefault();
        UsernamePasswordCredentials creds = new UsernamePasswordCredentials("user", "password");
        System.out.println(creds.getUserPrincipal().getName());
        System.out.println(creds.getPassword());
        HttpPost uploadFile = new HttpPost("http://10.0.0.45/home");


        MultipartEntityBuilder builder = MultipartEntityBuilder.create();
        builder.addTextBody("field1", "yes", ContentType.TEXT_PLAIN);

        // This attaches the file to the POST:
        File f = new File("D:\\chinta\\abc.txt");
        builder.addBinaryBody(
            "file",
            new FileInputStream(f),
            ContentType.APPLICATION_OCTET_STREAM,
            f.getName()
        );

        HttpEntity multipart = builder.build();
        uploadFile.setEntity(multipart);
        CloseableHttpResponse response = httpClient.execute(uploadFile);
        System.out.println("=s========================"+response.getStatusLine());

        HttpEntity responseEntity = response.getEntity();
    }

}

我在response.getstatus 中收到 404 错误。

我尝试了你的代码，它工作正常。 404通常意味着服务器端不存在请求url。也许你应该检查一下。
