Spring学习笔记（三十四）：关于http的get请求返回的数据过长问题

//get请求
public static String get(String url) throws Exception{
CloseableHttpClient httpClient = HttpClients.createDefault();
HttpGet httpGet = new HttpGet(url);
StringBuffer str = new StringBuffer();
String result = "";
try{
CloseableHttpResponse response = httpClient.execute(httpGet);
HttpEntity httpEntity = response.getEntity();
//解析返回的值
//方法一：直接转成string
//EntityUtils.toString(httpEntity, "UTF-8");
result = EntityUtils.toString(httpEntity,"UTF-8");
//方法二：取出inputStream，然后转string
//注意：这里用的时候有时候会出问题，就是数据量大的时候；有一次测试，返回的字符串长度为15716，结果只显示了部分的数据
//导致解析json时一直出错
//              InputStream in = httpEntity.getContent();
//              byte[] bytes = new byte[1024];
//              while(-1 != in.read(bytes)){
//                  str.append(new String(bytes,"UTF-8"));
//              }
//              //consume()
//              EntityUtils.consume(httpEntity);
}finally{
//close()
httpClient.close();
}
return result;
}
