我有一个客户端(java)将一些json数据发送到我的服务器(c ++)。在此之后我的服务器响应一些信息,这取决于我的java客户端的操作。现在它的作品。
Example body request:
{
"userEmail": "email@email.com",
"userPassword": "12345678"
}
服务器,接收电子邮件和密码并执行操作并发回回复。
但现在我需要更改我的java客户端以发送这样的请求:
{
"userInformation":{
"userEmail": "email@email.com",
"userPassword": "12345678"
}
}
此请求可用于登录。这是一个非常复杂的架构,所以我无法复制所有代码,但在登录类中我使用了gson(注意我只在c ++服务器上工作,我不在客户端工作,不可能联系那个让java客户端问他的人关于这个疑惑)
Java客户端 - 登录类
public final String userEmail;
public final String userPassword;
public LoginRequestArgs( String userEmail, String userPassword)
{
this.userEmail = userEmail;
this.userPassword = userPassword;
}
public static LoginRequestArgs fromStringJson(String data)
{
try
{
Gson gson = new Gson();
return gson.fromJson(data, LoginRequestArgs.class);
}
catch(Exception e)
{
return null;
}
}
public static LoginRequestArgs fromBytesJson(byte[] data)
{
if (data == null) return null;
try
{
String str = new String(data, "utf-8");
return fromStringJson(str);
}
catch (Exception e)
{
return null;
}
}
@Override
public String toJsonString()
{
try
{
Gson gson = new Gson();
return gson.toJson(this);
}
catch(Exception e)
{
return null;
}
}
@Override
public byte[] toJsonBytes()
{
try
{
return this.toJsonString().getBytes("utf-8");
}
catch (Exception e)
{
return null;
}
}
我有其他类连接到我的服务器并发送请求。此类调用login函数(请求是SerializableJSON变量)并将此请求发送到我的服务器request = LoginRequestArgs.fromStringJson(args.httpEntity);
(对于测试我使用一个其他客户端chrome扩展名)
我知道这可能有些难以理解但不容易解释所有事情。我试着解释一下这个问题。
真正的问题:我无法让java客户端发送内部的电子邮件和密码" userInformation"。有人可以帮帮我吗?感谢
编辑(其他身体申请示例):
{
"userInformation": {
"otherSection": {
"key1": "value1",
"key2": "value2"
}
}
}
EDIT 2(身份验证方法):
{
"authenticationMethod": {
"sessionId": {
"email": "email@email.com",
"password": "pass123"
}
},
"userInformation": {
"userId": "user",
"userPassword": "user123"
}
}
EDIT 3(TOKEN):
{
"authenticationMethod": {
"token": {
"token": "HDI393UDDNDMAY4758SAD"
}
},
"userInformation": {
"userId": "user",
"userPassword": "user123"
}
}
编辑4:
{
"sessionId":{
"email":"email@email.com",
"password":"dasdas"
},
"userInformation":{
"userId": "userId1",
"userPassword": "12345678"
}
}
我已经将这个json发送到我的c ++服务器,它的工作和我的解码会话ID也正常工作,这对我来说不是问题。但我需要发送sessionId(或令牌),但内部" AuthenticationMethod",它只是我现在需要实现的东西。注意" userInformation"它的例子和例子可以是例如" bookInformation"," carInformation" ,根据请求类型,我发送内部具有不同键/值的不同数据..但是在所有请求中始终必须使用身份验证方法(会话ID或令牌)。
像我向你展示的那样,我实现了这个:
public class SessionId {
public String email;
public String password;
public SessionId(String email, String password)
{
this.email = email;
this.password = password;
}
}
在我的类的构造中(可以是一个类,如LoginRequestArgs,登录cass)我称之为超级:
public UserInfo userInformation;
public SessionId sessionId;
public LoginRequestArgs(String email, String password,String userEmail, String userPassword)
{
super(email,password);
userInformation = new UserInfo(userEmail, userPassword);
}
static class UserInfo {
public String userId;
public String userPassword;
public UserInfo(String userEmail, String userPassword) {
this.userId = userEmail;
this.userPassword = userPassword;
}
}
所以现在,我只需要添加" authenticationMethod"在会话ID或令牌之前(我相信这样做的方式对两者都是一样的)
****编辑5 ********
login.java
public class LoginRequestArgs implements SerializableJSON {
public UserInfo userInformation;
public AuthenticationMethod authenticationMethod;
public LoginRequestArgs(String email, String password,String userId, String userPassword)
{
AuthenticationMethod auth = new SessionId(email, password);
setAuth(auth);
userInformation = new UserInfo(userId, userPassword);
}
public void setAuth(AuthenticationMethod authenticationMethod){
this.authenticationMethod = authenticationMethod;
}
static class UserInfo {
public String userId;
public String userPassword;
public UserInfo(String userEmail, String userPassword) {
this.userId = userEmail;
this.userPassword = userPassword;
}
}
SessionId.java
public class SessionId extends AuthenticationMethod {
Session sessionId;
public SessionId(String email, String password)
{
this.sessionId = new Session(email,password);
}
static class Session{
String email;
String password;
public Session(String email, String password)
{
this.email = email;
this.password = password;
}
}
}
AuthenticationMethod.java
public class AuthenticationMethod {
}
答案 0 :(得分:1)
您需要将LoginRequestArgs
类更改为以下内容:
public class LoginRequestArgs {
public UserInfo userInformation;
public LoginRequestArgs(String userEmail, String userPassword) {
userInformation = new UserInfo(userEmail, userPassword);
}
static class UserInfo {
public String userEmail;
public String userPassword;
public UserInfo(String userEmail, String userPassword) {
this.userEmail = userEmail;
this.userPassword = userPassword;
}
}
public static LoginRequestArgs fromStringJson(String data) {
try {
Gson gson = new Gson();
return gson.fromJson(data, LoginRequestArgs.class);
} catch (Exception e) {
return null;
}
}
public static LoginRequestArgs fromBytesJson(byte[] data) {
if (data == null)
return null;
try {
String str = new String(data, "utf-8");
return fromStringJson(str);
} catch (Exception e) {
return null;
}
}
}
以下是访问电子邮件和密码的方法:
loginRequestArgsInstance.userInformation.userEmail;
loginRequestArgsInstance.userInformation.userPassword;
您可能应该在此课程中添加一些getter和setter,或者至少确保userInformation
不是null
。
将会话详细信息包含在JSON中有多种方法。一种方法是修改你的java类。像这样:
Req.java
public class Req{
String data1;
String data2;
Auth authenticationMethod;
....
public void setAuth(Auth authenticationMethod){
this.authenticationMethod = authenticationMethod;
}
}
Auth.java
public class Auth{
....
}
AuthToken.java
public class AuthToken extends Auth {
Token token;
public AuthToken(String token) {
this.token = new Token(token);
}
static class Token {
String token;
public Token(String token) {
this.token = token;
}
}
}
AuthUserInfo.java
public class AuthUserInfo extends Auth {
UserInfo sessionId;
public AuthUserInfo(String email, String password) {
this.sessionId = new UserInfo(email, password);
}
static class UserInfo {
String email;
String password;
public UserInfo(String email, String password) {
this.email = email;
this.password = password;
}
}
}
以下是您可以使用这些课程的方法:
Req req = new Req(...);
Auth auth = new AuthToken(...);// OR: new AuthUserInfo(...);
req.setAuth(auth);
String json = new Gson().toJson(req);
另一种方法是在创建JSON后为其添加新属性。您可以看到如何执行此操作的示例here
