模拟HTTP 调用API接口

最近在写一些利用HTTP访问API的东东，做个记录，以备不时之需：

1：首先构造比较完整的API访问URL

HttpClient client = new HttpClient();HttpMethod method = new GetMethod(url);try {client.executeMethod(method);String r =method.getResponseBodyAsString();return r;}finally{method.releaseConnection();}

2：根据得返回的结果进行解析，目前这里得到的结果是XML这里采用如下的方式进行解析：

SAXBuilder sb = new SAXBuilder();StringReader reader = new StringReader(responseXml.trim());Document doc;try {doc = sb.build(reader);Element root = doc.getRootElement();String isSuccess  = getTextTrim(alipayRoot,"is_success");if(StringUtils.isNotBlank(isSuccess) && "F".equals(isSuccess)) {return null;}Element responseEle = root.getChild("response");Element userEle = responseEle.getChild("user");String isRealName  = getTextTrim(userEle,"is_certified");if(StringUtils.isNotBlank(isRealName) && "T".equals(isRealName)) {return Boolean.TRUE;}else{return Boolean.FALSE;}} catch (Throwable e) {                                    log.error("parseResponse fail:"+responseXml,e);return null;}
