Question

我一直在使用Codename One 模拟器进行开发和测试，一切正常。

然而，当我在真正的Android设备上测试它时，我得到405 Method Not Allowed错误。这发生在POST和GET请求上。

我怀疑导致问题的是@Consume和@Produces。我该如何解决这个问题？

以下是我的服务器端代码：

@GET
@Path("/all/{language}")
@Produces("application/json")
public final Response getAllCelebrities(@PathParam("language") String language) {
    String celebritiesJSONString = CelebrityActions.getAllCelebritiesNamesJSONString(language);
    return Response.ok(celebritiesJSONString).build();
}

@POST
@Path("/login")
@Consumes("application/x-www-form-urlencoded")
@Produces("text/plain")
public final Response login(
        @FormParam("loginid") String loginid,
        @FormParam("password") String password
) {
    System.out.println("login 0 started");
    Long fanID;
    try {
        fanID = AccountsActions.login(loginid, password);
    } catch (Exception e) {
        return Response.serverError().entity(e.getMessage()).build();
    }
    if (fanID == null) {
        return responseFanIDNotFoundError();
    }
    System.out.println("This is printed out!!!");
    System.out.println("login 100 ended");
    return Response.ok().build();
}

这是执行login（）方法后的日志：

login 0 started
This is printed out!!!
login 100 ended

这意味着服务器端方法已准备好返回200响应。

是什么导致Android客户端显示405 Method Not Allow错误？

编辑：我在这里添加我的客户端代码： （请注意，这个处理来自服务器的cookie）

public class Login extends PostConnection {

private final String LoginEndpoint = "account/login";

private String loginIDString;
private String loginPasswordString;

// Tested and works on simulator!
public Login(String loginIDString, String loginPasswordString) {
    super();
    endpoint = LoginEndpoint;
    this.loginIDString = loginIDString;
    this.loginPasswordString = loginPasswordString;
}

@Override
protected void prepareParametersMap() {
    parametersMap = new HashMap<>();
    parametersMap.put("loginid", loginIDString);
    parametersMap.put("password", loginPasswordString);
}

}

public abstract class PostConnection extends PostPutConnection {

public PostConnection() {
    super();
}

public boolean connect() throws IOException {
    connectionRequest.setHttpMethod("POST");
    return super.connect();
}
}

public abstract class PostPutConnection extends Connection {

protected HashMap<String, String> parametersMap;

public PostPutConnection() {
    super();
}

protected static final void setPostParameters(ConnectionRequest connectionRequest, HashMap<String, String> parametersMap) {
    Set<String> paramateterKeys = parametersMap.keySet();
    Iterator<String> parameterKeysIterator = paramateterKeys.iterator();
    while (parameterKeysIterator.hasNext()) {
        String key = parameterKeysIterator.next();
        String value = parametersMap.get(key);
        connectionRequest.addArgument(key, value);
    }
}

protected abstract void prepareParametersMap();

public boolean connect() throws IOException {
    prepareParametersMap();
    setPost();
    setPostParameters();
    return super.connect();
}

private void setPostParameters() {
    setPostParameters(connectionRequest, parametersMap);
}

private final void setPost() {
    connectionRequest.setPost(true);
}
}

public abstract class Connection {

private final static String protocol = "http";
private final static String domain = "192.168.0.109:20000";

protected ConnectionRequest connectionRequest;
protected String endpoint;

public Connection() {
    super();
    init();
}

protected void init() {
    connectionRequest = new ConnectionRequest();
    connectionRequest.setCookiesEnabled(true);
    ConnectionRequest.setUseNativeCookieStore(true);
}

public boolean connect() throws IOException {
    connectionRequest.setUrl(protocol + "://" + domain + "/" + endpoint);
    NetworkManager.getInstance().addToQueueAndWait(connectionRequest);
    int responseCode = getResponseCode();
    return responseCode == 200 ? true : false;
}

private int getResponseCode() {
    int responseCode = connectionRequest.getResponseCode();
    return responseCode;
}
}

以下另一种方法： （请注意，这个不处理Cookie）

public class GetAllCelebrities extends GetConnection {

private final String GetCelebritiesEndpoint = "celebrity/all";

public GetAllCelebrities(String language) {
    super();
    endpoint = GetCelebritiesEndpoint + "/" + language;
}

}

public abstract class GetConnection extends Connection {

    private Map<String, Object> responseData;

    public GetConnection() {
        super();
    }

    public boolean connect() throws IOException {
        connectionRequest.setHttpMethod("GET");
        boolean connectResult = super.connect();
        if (!connectResult) {
            return false;
        }
        responseData = getResponseResult();
        return true;
    }

    private Map<String, Object> getResponseResult() throws IOException {
        byte[] responseData = connectionRequest.getResponseData();
        ByteArrayInputStream responseDataBAIS = new ByteArrayInputStream(responseData);
        InputStreamReader responseDataISR = new InputStreamReader(responseDataBAIS, "UTF-8");
        JSONParser responseDateJSONParser = new JSONParser();
        Map<String, Object> responseResult = responseDateJSONParser.parseJSON(responseDataISR);
        return responseResult;
    }

    public Map<String, Object> getResponseData() {
        return responseData;
    }
}

它被称为：

private Map<String, Object> fetchCelebrities() throws IOException {
    GetAllCelebrities getAllCelebrities = new GetAllCelebrities("en");
    getAllCelebrities.connect();
    return getAllCelebrities.getResponseData();
}

private boolean performLogin() throws IOException {
    String loginIDString = loginID.getText();
    String loginPasswordString = loginPassword.getText();
    Login login = new Login(loginIDString, loginPasswordString);
    boolean loginResult = login.connect();
    return loginResult;
}

Answer 1

阅读所有这些代码有点难，但我会冒险根据服务器消息猜测。您已经在post put类中将方法设置为“PUT”，但服务器尚不支持该方法。

调试这些东西的最佳方法是使用模拟器中的网络监视器。它显示了流量，并且会使这些事情变得非常清楚
