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);}
