将 Jersey 客户端转换为 HttpUrlConnection

Question

我有一个从 API 检索 jwt 令牌的 Jersey 客户端。

这是代码

public static final String INFO_ENDPOINT = "http://10.1.9.10:7100/Info/";

private static final String INFO_USERNAME = "user";

private static final String INFO_PASSWORD = "password";

private static final String AUTH_PATH = "auth";

private String token;

private final Client client;

public JerseyClient() {

    ClientConfig cc = new DefaultClientConfig();

    cc.getClasses().add(MultiPartWriter.class);

    client = Client.create(cc);

}

public void authenticate() {

    try {

        WebResource resource = client.resource(INFO_ENDPOINT + AUTH_PATH);

        StringBuilder sb = new StringBuilder();

        sb.append("{\"username\":\"" + INFO_USERNAME + "\",");

        sb.append("\"password\":\"" + INFO_PASSWORD + "\"}");

        ClientResponse clientResp = resource.type("application/json")

                                            .post(ClientResponse.class, sb.toString());

        String content = clientResp.getEntity(String.class);

        System.out.println("Response:" + content);

        token = content.substring(content.indexOf("\"token\":") + 9,

                                  content.lastIndexOf("\""));

        System.out.println("token " + token);

    } catch (ClientHandlerException | UniformInterfaceException e) {

    }

}

上面的代码返回一个 jwt 令牌，然后用作另一个调用的密钥。

我正在尝试将其转换为使用 HttpUrlConnection。但这似乎不起作用

这是我试过的。它不会给出错误，但也不返回令牌。响应为空

try {

    URL url = new URL("http://10.1.9.10:7100/Info/auth");

    HttpURLConnection conn = (HttpURLConnection) url.openConnection();

    conn.setDoOutput(true);

    conn.setRequestMethod("POST");

    conn.setRequestProperty("Content-Type", "application/json");

    conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");

    conn.setRequestProperty("accept", "application/json");

    String input = "{\"username\":user,\"password\":\"password\"}";

    OutputStream os = conn.getOutputStream();

    os.write(input.getBytes());

    }

我的问题是我无法转换.post(ClientResponse.class, sb.toString()) 为 HttpUrlConnection。

我错过了什么，或者我做错了什么？

问题已解决。代码按原样工作。问题是我缺少 json 值字符串的引号本来应该String input = "{\"username\":\"user\",\"password\":\"password\"}";
