Android使用httpclient上传文件到服务器

public void uploadFile(File file, String url) {  
        if (!file.exists()) {  
            return;  
        }  
        PostMethod postMethod = new PostMethod(url);  
        try {  
            //FilePart：用来上传文件的类  
        FilePart fp = new FilePart("filedata", file);  
            Part[] parts = { fp };  
  
            //对于MIME类型的请求，httpclient建议全用MulitPartRequestEntity进行包装  
            MultipartRequestEntity mre = new MultipartRequestEntity(parts, postMethod.getParams());  
            postMethod.setRequestEntity(mre);  
            HttpClient client = new HttpClient();  
            client.getHttpConnectionManager().getParams().setConnectionTimeout(50000);// 设置连接时间  
            int status = client.executeMethod(postMethod);  
            if (status == HttpStatus.SC_OK) {  
                System.out.println(postMethod.getResponseBodyAsString());  
            } else {  
                System.out.println("fail");  
            }  
        } catch (Exception e) {  
            e.printStackTrace();  
        } finally {  
            //释放连接  
            postMethod.releaseConnection();  
        }  
    }
