API Get by string可以翻译为'按字符串获取API”。具体实现方法请见以下示例代码:
//假设需要获取的API为 https://example.com/api/items //首先将API的字符串表示定义为一个变量 String apiUrl = "https://example.com/api/items";
//然后使用Java中的URL类将该API转化为URL对象 URL url = new URL(apiUrl);
//接下来使用Java中的HttpURLConnection类打开与该URL对应的连接 HttpURLConnection connection = (HttpURLConnection) url.openConnection();
//设置请求类型为GET并发送请求 connection.setRequestMethod("GET"); connection.connect();
//最后读取接收到的API响应数据并进行处理 BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream())); String response = "", line = ""; while ((line = reader.readLine()) != null) { response += line; } reader.close();
//在这里可以对response进行进一步处理,比如将其转化为JSON格式、XML格式等等
