使用httpclient、jame的mime4j和httppost方法上传速度较慢

httpclient mime post http java

Austin Hanson · 技术社区 · 15 年前

我正在使用httppost上载一个多部分数据块,并将其输入httpclient对象执行方法,如下所示:

HttpPost loginPost = new HttpPost(LOGIN_URL);
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("_email", mEmailAddress));
params.add(new BasicNameValuePair("lpassword", mPassword));

UrlEncodedFormEntity entity = new UrlEncodedFormEntity(params, "UTF-8");

loginPost.setEntity(entity);
HttpResponse resp = mHttpClient.execute(loginPost);

HttpPost post = new HttpPost(UPLOAD_URL);
FileBody bin = new FileBody(file);
MultipartEntity me = new MultipartEntity();

me.addPart("stuff", new StringBody(stuff));
me.addPart("file", bin);

post.setEntity(new RequestEntityEx(me, handler));
mHttpClient.execute(post);

现在,登录和发布工作-很好,但上传速度非常慢。我已经测试了我的互联网连接,它比应该的慢得多(大约是1兆字节/秒,上传3兆字节的文件需要5分钟(而不是30秒)。

有人有什么想法吗?

我发现httpclient比普通的https方式慢9倍。我不知道为什么,谁都知道怎么了。

这基本上是我的代码

private static HttpClient httpClient = new DefaultHttpClient();
private static HttpPost httpPost = new HttpPost(RRD_URL);

    public static String sendData(List<NameValuePair> data) {
    StringBuffer buffer = new StringBuffer();
    BufferedReader rd = null;
    try {
        httpPost.setEntity(new UrlEncodedFormEntity(data));
        HttpResponse httpResponse = httpClient.execute(httpPost);

        rd = new BufferedReader(new InputStreamReader(httpResponse.getEntity().getContent()));
        String line;
        while ((line = rd.readLine()) != null) {
            buffer.append(line);
        }
    } catch (IOException e) {
        e.printStackTrace(System.out);
    } finally {
        try {
            if (rd != null) {
                rd.close();
            }
        } catch (IOException e) {
            e.printStackTrace(System.out);
        }
    }

    return buffer.toString();
}
