1. 只拼接参数：(适用于拼接的参数中没有特殊字符)
/*** @Description get请求URL拼接参数* @param url* 接口地址(无参数)* @param map* 拼接参数集合*/public static String getAppendUrl(String url, Map<String, String> map) {if (map != null && !map.isEmpty()) {StringBuffer buffer = new StringBuffer();Iterator<Entry<String, String>> iterator = map.entrySet().iterator();while (iterator.hasNext()) {Entry<String, String> entry = iterator.next();if (StringUtils.isEmpty(buffer.toString())) {buffer.append("?");} else {buffer.append("&");}buffer.append(entry.getKey()).append("=").append(entry.getValue());}url += buffer.toString();}return url;}
2.拼接参数并且URL编码(适用于拼接参数中有特殊字符 eg:空格 之类的)
/*** @Description get请求URL拼接参数 & URL编码* @param url* 接口地址(无参数)* @param map* 拼接参数集合*/public String getAppendUrl(String url, Map<String, String> map) {StringBuffer buffer = new StringBuffer();if (map != null && !map.isEmpty()) {Iterator<Entry<String, String>> iterator = map.entrySet().iterator();while (iterator.hasNext()) {Entry<String, String> entry = iterator.next();if (StringUtils.isEmpty(buffer.toString())) {buffer.append("?");} else {buffer.append("&");}buffer.append(entry.getKey()).append("=").append(entry.getValue());}}return url + URLEncoder.encode(buffer.toString());}
