Question

我正在尝试使用apache HttpClient api将“myfile.txt”文件作为“uploaded.txt”上传到apache服务器（WAMP），但我收到“404 not found”状态。

public class Httpupload1 {


    public static void main(String[] args) throws Exception 
    {

        String url = "http://username:password@localhost/uploaded.txt";

        DefaultHttpClient httpclient = new DefaultHttpClient();

        HttpPost httppost = new HttpPost(url);
        MultipartEntity entity = new MultipartEntity();

        ContentBody body = new FileBody(
                new File("C:/Users/username/Desktop/myfile.txt"),
                ContentType.APPLICATION_OCTET_STREAM
                );

        entity.addPart("file", body);
        httppost.setEntity(entity);

        HttpResponse response = httpclient.execute(httppost);
        System.out.println(response.getStatusLine());


    }
}

DefaultHttpClient和AndroidHttpClient都没有像user：password @这样的摘要网址... 相反，您需要使用B64编码才能将您的凭据传输到apache服务器。

这样做试试这个

     public String getB64Auth (String login, String pass) {
       String source=login+":"+pass;
       String auth="Basic "+android.util.Base64.encodeToString(source.getBytes(),android.util.Base64.URL_SAFE|Base64.NO_WRAP);
       return auth;
     }

然后必须将生成的字符串添加到您的HttpPost对象

String auth = getB64Auth("username","password");
HttpPost postRequest = new HttpPost(URL);
postRequest.addHeader("Authorization",auth);

你还需要接受服务器端数据的东西（如php脚本）。我怀疑“uploaded.txt”是否会这样做...... 此脚本还负责处理，命名和保存接收的文件。例如，您可以使用添加到MultiPartEntity的StringBody来传递用于在服务器端保存文件的名称。
