很早之前，http工具一直用Httpclient，后来觉得jodd更简单，就倾向于jodd的一些工具库了。

使用jodd遇到一个问题：
  当邮件内容比较大时，比如1万多字符的时候，发送邮件失败。
Sendcloud服务器所在的Nginx，提示
“

提交工单，与客服和技术支持，交流了几个小时，终于解决了问题。

第1种方法：使用官方给的Apache Httpclient的例子，发送邮件。
第2种方法：原来用Jodd，使用方式有问题。

Map<String, String> queryMap = new HashMap<String, String>();

		queryMap.put("api_user", API_USER);

		queryMap.put("api_key", API_KEY);

		queryMap.put("from", FROM);

		queryMap.put("to", to);

		queryMap.put("subject", subject);

		queryMap.put("html", html.substring(0,html.length()));

		HttpResponse response = HttpRequest.post(URL)// .contentType(contentType)

				.query(queryMap).send();

		String body = response.bodyText();

Apache发送:

public static void send(String to, String subject, String html) {

		if (!check()) {

			return;

		}

		String url = URL;

		HttpClient httpclient = new DefaultHttpClient();

		HttpPost httpost = new HttpPost(url);

		List nvps = new ArrayList();

		nvps.add(new BasicNameValuePair("api_user", API_USER));

		nvps.add(new BasicNameValuePair("api_key", API_KEY));

		nvps.add(new BasicNameValuePair("from", FROM));

		nvps.add(new BasicNameValuePair("to", to));

		nvps.add(new BasicNameValuePair("subject", subject));

		nvps.add(new BasicNameValuePair("html", html));

		try {

			httpost.setEntity(new UrlEncodedFormEntity(nvps, "UTF-8"));

			HttpResponse response = httpclient.execute(httpost);

			if (response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) { // 正常返回

				HttpEntity entity = response.getEntity();

				System.out.println(EntityUtils.toString(entity));

			} else {

				System.err.println("error");

			}

		} catch (Exception e) {

			e.printStackTrace();

		}

	}

public static void send(String to, String subject, String html) {

		if (!check()) {

			return;

		}

		Map<String, Object> queryMap = new HashMap<String, Object>();

		queryMap.put("api_user", API_USER);

		queryMap.put("api_key", API_KEY);

		queryMap.put("from", FROM);

		queryMap.put("to", to);

		queryMap.put("subject", subject);

		queryMap.put("html", html.substring(0,html.length()));

		HttpResponse response = HttpRequest.post(URL)// .contentType(contentType)

				.form(queryMap).send();

		String body = response.bodyText();

		try {

			JSONObject jsonObject = JSONObject.parseObject(body);

			MailMessage msg = JSONObject.toJavaObject(jsonObject,

					MailMessage.class);

			String sendInfo = "to=" + to + ",subject=" + subject;

			if (msg.getMessage().equals(MailMessage.ERROR)) {

				logger.error("sendcloud,send mail failed:" + msg + ",sendInfo:"

						+ sendInfo);

			} else if (msg.getMessage().equals(MailMessage.SUCCESS)) {

				logger.info("sendcloud,send mail ok,sendInfo:" + sendInfo);

			}

		} catch (Exception e) {

			logger.error("send mail failed",e);

			logger.info(body);

		}

		// System.out.println(response);
