基本上,我想从我的Android设备上传文件到http网站.但是,我不知道如何做到这一点.我在设备上使用java,我想在服务器端使用PHP.我只想上传文件,不要在服务器上做任何事情.

任何人都可以提供代码和/或一个很好的链接,我需要什么？我在这方面几乎没有任何经验,我很失落.

谢谢,
NS

PS.我没有PHP编码的经验.

public class Uploader extends Activity {

    private String Tag = "UPLOADER";
    private String urlString = "YOUR_ONLINE_PHP";
    HttpURLConnection conn;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        String exsistingFileName = "/sdcard/uploader/data/testfile";

        String lineEnd = "\r\n";
        String twoHyphens = "--";
        String boundary = "*****";
        try {
            // ------------------ CLIENT REQUEST

            Log.e(Tag,"Inside second Method");

            FileInputStream fileInputStream = new FileInputStream(new File(
                    exsistingFileName));

            // open a URL connection to the Servlet

            URL url = new URL(urlString);

            // Open a HTTP connection to the URL

            conn = (HttpURLConnection) url.openConnection();

            // Allow Inputs
            conn.setDoInput(true);

            // Allow Outputs

            DataOutputStream dos = new DataOutputStream(conn.getoutputStream());

            dos.writeBytes(twoHyphens + boundary + lineEnd);
            dos
                    .writeBytes("Content-disposition: post-data; name=uploadedfile;filename="
                            + exsistingFileName + "" + lineEnd);
            dos.writeBytes(lineEnd);

            Log.e(Tag,"Headers are written");

            // create a buffer of maximum size

            int bytesAvailable = fileInputStream.available();
            int maxBufferSize = 1000;
            // int bufferSize = Math.min(bytesAvailable,maxBufferSize);
            byte[] buffer = new byte[bytesAvailable];

            // read file and write it into form...

            int bytesRead = fileInputStream.read(buffer,bytesAvailable);

            while (bytesRead > 0) {
                dos.write(buffer,bytesAvailable);
                bytesAvailable = fileInputStream.available();
                bytesAvailable = Math.min(bytesAvailable,maxBufferSize);
                bytesRead = fileInputStream.read(buffer,bytesAvailable);
            }

            // send multipart form data necesssary after file data...

            dos.writeBytes(lineEnd);
            dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);

            // close streams
            Log.e(Tag,"File is written");
            fileInputStream.close();
            dos.flush();
            dos.close();

        } catch (MalformedURLException ex) {
            Log.e(Tag,"error: " + ex.getMessage(),ex);
        }

        catch (IOException ioe) {
            Log.e(Tag,"error: " + ioe.getMessage(),ioe);
        }

        try {
            BufferedReader rd = new BufferedReader(new InputStreamReader(conn
                    .getInputStream()));
            String line;
            while ((line = rd.readLine()) != null) {
                Log.e("Dialoge Box","Message: " + line);
            }
            rd.close();

        } catch (IOException ioex) {
            Log.e("MediaPlayer","error: " + ioex.getMessage(),ioex);
        }
    }
}

当我使用没有SSL的服务器(http://192.168.1.30:2999/autenticador和https://192.168.1.30:2901/)时,授权成功.但是,当我使用自签名证书时,我遇到了问题,返回错误401,未授权,身份验证失败：无法获取访问令牌.我不知道它是如何以及为什么会发生的.

观察：证书在我的计算机上注册,如信任,然后我看到地址栏为绿色.

客户端：

@SpringBootApplication
@EnableOAuth2Sso
public class Application {
    public static void main(String[] args) throws KeyManagementException,NoSuchAlgorithmException,KeyStoreException {
        SpringApplication.run(Application.class,args);
    }
}

服务器上的OAuth 2.0配置：

@Configuration
@EnableAuthorizationServer
public class OAuthConfiguration extends AuthorizationServerConfigurerAdapter{
    @Autowired
    private AuthenticationManager authenticationManager;

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
         endpoints.authenticationManager(authenticationManager);
    }

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory()
        .withClient("client")
        .authorizedGrantTypes("authorization_code")
        .scopes("read","trust")
        .resourceIds("RESOURCE_ID")
        .secret("secret");
    }
}

这是服务器登录成功后的客户端日志：
