Java根据URL连接请求JSON数据解析代码_java依据token和url请求json数据-优快云博客

本文介绍了两种从指定URL加载航班信息JSON数据的方法。一种是通过StringBuilder拼接读取到的数据，另一种则是使用StringBuffer进行拼接。这两种方法都能有效地处理HTTP请求，并将返回的流转换为字符串形式的JSON数据。

/**
* 方法描述：根据航班URL接连请求，获取航班信息数据（json）
* 属性：url
* 调用：fltJsonDataParser方法中调用
* */
public static String loadJson(String url) {
StringBuilder json = new StringBuilder();
try {
URL urlObject = new URL(url);
URLConnection uc = urlObject.openConnection();
BufferedReader in = new BufferedReader(new InputStreamReader(uc.getInputStream()));
String inputLine = null;
while ((inputLine = in.readLine()) != null) {
json.append(inputLine);
}
in.close();
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return json.toString();
}

public static String getJsonString(String urlPath) throws Exception {
URL url = new URL(urlPath);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.connect();
InputStream inputStream = connection.getInputStream();
// 对应的字符编码转换
Reader reader = new InputStreamReader(inputStream, "UTF-8");
BufferedReader bufferedReader = new BufferedReader(reader);
String str = null;
StringBuffer sb = new StringBuffer();
while ((str = bufferedReader.readLine()) != null) {
sb.append(str);
}
reader.close();
connection.disconnect();
return sb.toString();
