web服务-如何将http-get-response(restfulws)读取为java.io.file

Question

File file = new File("C:\testing.txt")

我们能通过任何方式实现吗？比如：

File file = new File("https://stackoverflow.com/ws-server/lookup/1.0/1234")

下面的Web服务以字符串形式向我返回与txt相同的文件内容。https://stackoverflow.com/ws-server/lookup/1.0/1234

有人能告诉我是否可行吗。

Answer 1

您可以将响应写入File。

请看这个答案了解详细信息。

在此之后，您可以按照习惯打开File。

Answer 2

这是一个方便的实现吗？注意：它使用Apache HttpComponents客户端和Apache Commons IO

public class RunApp {
public static void main(String[] args) throws Exception {
    CloseableHttpClient httpclient = HttpClients.createDefault();
    try {
        HttpGet httpget = new HttpGet("http://localhost/");
        System.out.println("Executing request " + httpget.getRequestLine());
        // Create a custom response handler
        ResponseHandler<File> responseHandler = new ResponseHandler<File>() {
            public File handleResponse( final HttpResponse response) throws ClientProtocolException, IOException {
                int status = response.getStatusLine().getStatusCode();
                if (status >= 200 && status < 300) {
                    HttpEntity entity = response.getEntity();
                    File file = new File("Desired-filename");
                    IOUtils.copy(entity.getContent(), new FileOutputStream(file));
                    return file;
                } else {
                    throw new ClientProtocolException("Unexpected response status: " + status);
                }
            }
        };
        File file = httpclient.execute(httpget, responseHandler);
        System.out.println("----------------------------------------");
        System.out.println(file.getAbsolutePath());
    } finally {
        httpclient.close();
    }
}
}

一个更短的解决方案是使用Apache Commons IO 中的FileUtils.copyURLToFile(URL，File(
