Gemfire 的 Http 响应无效？

Question

enter image description here public class GemfireTest 扩展了 SecurityManager {

            public static void main(String[] args) throws NameResolutionException, TypeMismatchException, QueryInvocationTargetException, FunctionDomainException, IOException {

                System.setProperty("gemfire.locators", "localhost[8091]");
                Properties properties = new Properties();

             ServerLauncher serverLauncher = new ServerLauncher.Builder()

                        .setMemberName("server1")
                        .setServerPort(40404)
                        .set("start-locator", "localhost[8091]")
            .build();
                serverLauncher.start();
                System.out.println(serverLauncher.status());
String restapi ="http://localhost:8091/gemfire-api/v1/";
             //   URLConnection urlConnection = new URL(restapi).openConnection();
                try {
                    URL obj = new URL(restapi);
                    HttpURLConnection con = (HttpURLConnection) obj.openConnection();
                    con.setRequestMethod("GET");
                    con.setRequestProperty("accept","application/json");
                    int responseCode = con.getResponseCode();
                    System.out.println(responseCode);
                   // if (responseCode == HttpURLConnection.HTTP_OK) { // success
                        BufferedReader in = new BufferedReader(new InputStreamReader(
                                con.getInputStream()));
                        String inputLine;
                        StringBuffer response = new StringBuffer();

                        while ((inputLine = in.readLine()) != null) {
                            response.append(inputLine);
                        }
                        in.close();

                        // print result
                        System.out.println("reason"+response.toString());

Server in C:\Users\xxx\IdeaProjects\Gemfire on DESKTOP-MRCV2EH[40404] as server1 is currently online.

获取响应代码：-1，无效的 Http 响应。

我该如何解决这个问题？

Answer 1

您的源代码中似乎缺少 GEODE_HOME 环境变量，服务器在启动期间需要它来找到启动 REST 所需的库 API ，特别是 install-dir/tools/Extensions/geode-web-api-n.n.n.war。您可以在 Setup and Configuration.

中找到更多详细信息

希望这对您有所帮助。干杯。

我已经在本地测试了您的源代码（加上 one/two 小的修改），一切似乎都运行良好：

public static void main(String[] args) throws IOException {
    Integer httpServicePort = 8080;
    ServerLauncher serverLauncher = 
        new ServerLauncher.Builder()
        .set("log-file", "")
        .set("http-service-port", httpServicePort.toString())   
        .set("start-dev-rest-api", "true")
        .set("http-service-bind-address", "localhost")
        .setPdxReadSerialized(true)
        .build();

    serverLauncher.start();
    System.out.println("REST server successfully started, press any key to stop it...");
    String restapi ="http://localhost:" + httpServicePort + "/gemfire-api/v1/";

    try {
        URL obj = new URL(restapi);
        HttpURLConnection con = (HttpURLConnection) obj.openConnection();
        con.setRequestMethod("GET");
        con.setRequestProperty("accept","application/json");
        int responseCode = con.getResponseCode();
        System.out.println("Response Code: " + responseCode);

         if (responseCode == HttpURLConnection.HTTP_OK) { // success
               BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
               String inputLine;
               StringBuffer response = new StringBuffer();
               while ((inputLine = in.readLine()) != null) {
                   response.append(inputLine);
               }

               in.close();
               System.out.println("Response: " + response.toString());
         }
    } catch (Exception exception) {
        exception.printStackTrace();
    }

    System.in.read();
    serverLauncher.stop();
    System.exit(0);
}

运行上面的程序打印如下：

REST server successfully started, press any key to stop it...
Response Code: 200
Response: {  "regions" : [ ]}

你是否正确设置了GEODE_HOME环境变量？，执行curl命令时使用的port呢？，与你通过[=配置的数字相同吗？ 15=] 属性?。干杯。
