问题描述

好的，我有一个授权应用程序，我需要保存clientID，clientSecret，accessToken和refreshToken。 我试图保存，但我做错了，他只为所有字段保存了1个值。 请检查代码。 这是一个很长的代码，sharedPreference部分到底。 

public class FragmentRegistration extends Fragment {
View mainView;

EditText name, username, email, password;
Button button;

ApiClient apiClient = ApiClient.getInstance();

SupportopObj supportopObj = new SupportopObj();
SupportopObjActivate supportopActivate = new SupportopObjActivate();
SupportObjToken supportopToken = new SupportObjToken();

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    mainView = inflater.inflate
            (R.layout.registration, container, false);

    username = mainView.findViewById(R.id.username);
    email = mainView.findViewById(R.id.email);
    password = mainView.findViewById(R.id.password);
    name = mainView.findViewById(R.id.name);
    button = mainView.findViewById(R.id.register);

    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            String s = name.getText().toString();
            String split[] = s.split(" ");

            supportopObj.setFirstName(split[0]);
            supportopObj.setLastName(split[1]);
            supportopObj.setUsername(username.getText().toString());
            supportopObj.setEmail(email.getText().toString());
            supportopObj.setPassword(password.getText().toString());

            supportopActivate.setUsername(supportopObj.getUsername());
            supportopActivate.setEmail(supportopObj.getEmail());
            supportopActivate.setPassword(supportopObj.getPassword());
            supportopActivate.setType("generic");

            registerCall();


            getSaveData();
        }
    });

    return mainView;
}


public void registerCall() {

    Call<ResponseBody> call = apiClient.registration(supportopObj);
    call.enqueue(new Callback<ResponseBody>() {
        @Override
        public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
            if (response.isSuccessful()) {
                //VersionDataInfo versionDataInfo = response.body();
                clientCall();

            } else {
                Toast.makeText(getActivity(), "Something went wrong", Toast.LENGTH_SHORT).show();
                clientCall();
            }
        }

        @Override
        public void onFailure(Call<ResponseBody> call, Throwable t) {
            Toast.makeText(getActivity(), "Error...", Toast.LENGTH_SHORT).show();
        }
    });
}

public void clientCall() {
    Call<ResponseBody> callActive = apiClient.activation(supportopActivate);
    callActive.enqueue(new Callback<ResponseBody>() {
        @Override
        public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {

            if (response.isSuccessful()) {

                try {
                    String data = response.body().string();

                    saveData(client_id);
                    saveData(client_secret);

                    tokenCall(client_id, client_secret);

                } catch (JSONException | IOException e) {
                    e.printStackTrace();
                }

            } else {
                Toast.makeText(getActivity(), "error", Toast.LENGTH_SHORT).show();
            }
        }

        @Override
        public void onFailure(Call<ResponseBody> call, Throwable t) {
            Toast.makeText(getActivity(), "Error in activation", Toast.LENGTH_SHORT).show();
        }
    });
}

public void tokenCall(String client_id, final String client_secret) {
    Call<ResponseBody> token = apiClient.getToken("password", client_id, client_secret,
            supportopActivate.getEmail(), supportopActivate.getPassword());

    token.enqueue(new Callback<ResponseBody>() {
        @Override
        public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
            if (response.isSuccessful()) {
                try {
                    String dataAccess = response.body().string();
                    JSONObject obj = new JSONObject(dataAccess);

                    String access_token = obj.getString("access_token");
                    String refresh_token = obj.getString("refresh_token");
                    String client_id = obj.getString("client_id");

                    supportopToken.setGrantType("refresh_token");
                    supportopToken.setClientId(client_id);
                    supportopToken.setClientSecret(client_secret);
                    supportopToken.setRefreshToken(refresh_token);

                    saveData(access_token);
                    saveData(refresh_token);

                    newTokenCall();

                } catch (IOException | JSONException e) {
                    e.printStackTrace();
                }
            } else {
                Toast.makeText(getActivity(), "Something wrong.....", Toast.LENGTH_SHORT).show();
            }
        }

        @Override
        public void onFailure(Call<ResponseBody> call, Throwable t) {
            Toast.makeText(getActivity(), "You're on failure", Toast.LENGTH_SHORT).show();
        }
    });
}

public void newTokenCall() {
    Call<ResponseBody> newToken = apiClient.newToken(supportopToken);
    newToken.enqueue(new Callback<ResponseBody>() {
        @Override
        public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
            if (response.isSuccessful()) {
                Toast.makeText(getActivity(), String.valueOf(response.body()), Toast.LENGTH_SHORT).show();
            }
        }

        @Override
        public void onFailure(Call<ResponseBody> call, Throwable t) {
            Toast.makeText(getActivity(), "You're on failure getting new Token", Toast.LENGTH_SHORT).show();
        }
    });
}

public void saveData(String data) {
    SharedPreferences preferences = this.getActivity().getSharedPreferences("Saved_data", Context.MODE_PRIVATE);
    SharedPreferences.Editor editor = preferences.edit();
    editor.putString("Data", data).apply();
}

public void getSaveData() {
    SharedPreferences preferences = this.getActivity().getSharedPreferences("Saved_data", Context.MODE_PRIVATE);
    String client_id = preferences.getString("Data", "client_id");
    String client_secret = preferences.getString("Data", "client_secret");
    String access_token = preferences.getString("Data", "access_token");
    String refresh_token = preferences.getString("Data", "refresh_token");
    Toast.makeText(getActivity(), client_id + " " + client_secret
            + " " + access_token + " " + refresh_token,Toast.LENGTH_SHORT).show();
}}

在最后的方法，当我试图让客户端ID获取的数据168e3903996c90818ecabaf1c60ff4108a2f6d438e8bcb788a7fe5ef5224d1的clientSecret，和的accessToken太refreshToken。 代码有什么问题？

如果需要在SharedPreferences保存不同的数据，则需要使用不同的密钥

像这样 

public void saveData(String key,String data) {
    SharedPreferences preferences = this.getActivity().getSharedPreferences("Saved_data", Context.MODE_PRIVATE);
    SharedPreferences.Editor editor = preferences.edit();
    editor.putString(key, data).apply();
}

比这样打电话 

saveData("client_id",client_id);
saveData("client_secret",client_secret);
saveData("access_token",access_token);      
saveData("refresh_token",refresh_token);

比得到这样的所有数据 

public void getSaveData() {
    SharedPreferences preferences = this.getActivity().getSharedPreferences("Saved_data", Context.MODE_PRIVATE);
    String client_id = preferences.getString("client_id", "client_id");
    String client_secret = preferences.getString("client_secret", "client_secret");
    String access_token = preferences.getString("access_token", "access_token");
    String refresh_token = preferences.getString("refresh_token", "refresh_token");
    Toast.makeText(getActivity(), client_id + " " + client_secret
            + " " + access_token + " " + refresh_token,Toast.LENGTH_SHORT).show();
}}

你正在尝试的是这个： 

saveData(access_token);
saveData(refresh_token);

你可以做什么： 

saveData(access_token, refresh_token);

public void saveData(String token1, String token2) {
    SharedPreferences preferences = this.getActivity().getSharedPreferences("Saved_data", Context.MODE_PRIVATE);
    SharedPreferences.Editor editor = preferences.edit();
    editor.putString("Data1", token1).apply();
    editor.putString("Data2", token2).apply();
}

正如你所说，它只保存了一个值，因为你正在重写你的共享首选项。

看起来你的值被替换只是因为你使用相同的id。

下面的代码可能适合您。 

public void saveData(String key_name,String data) {
    SharedPreferences preferences = this.getActivity().getSharedPreferences("Saved_data", Context.MODE_PRIVATE);
    SharedPreferences.Editor editor = preferences.edit();
    editor.putString(key_name, data).apply();
}

并调用此方法，如下所示。 

saveData("client_id","abcded");

使用.commit()

如果保存有效，则返回true，否则返回false。

这是因为您尝试将所有值保存在同一个键中，请为每个值尝试不同的键 

public static final String KEY_ACCESS_TOKEN = "accessToken";
public static final String KEY_REFRESH_TOKEN = "refreshToken";
public static final String KEY_CLIENT_ID = "clientId";
public static final String KEY_CLIENT_SECRET = "clientSecret";

public void saveData(String key,String data) {
    SharedPreferences preferences = this.getActivity().getSharedPreferences("Saved_data", Context.MODE_PRIVATE);
    SharedPreferences.Editor editor = preferences.edit();
    editor.putString(key, data).apply();
}

public void getSaveData() {
    SharedPreferences preferences = this.getActivity().getSharedPreferences("Saved_data", Context.MODE_PRIVATE);
    String client_id = preferences.getString(KEY_CLIENT_ID , "client_id");
    String client_secret = preferences.getString(KEY_CLIENT_SECRET , "client_secret");
    String access_token = preferences.getString(KEY_ACCESS_TOKEN , "access_token");
    String refresh_token = preferences.getString(KEY_REFRESH_TOKEN , "refresh_token");
    Toast.makeText(getActivity(), client_id + " " + client_secret
            + " " + access_token + " " + refresh_token,Toast.LENGTH_SHORT).show();
}}

同时保存数据 

saveData(KEY_ACCESS_TOKEN ,access_token);
saveData(KEY_REFRESH_TOKEN ,refresh_token);
saveData(KEY_CLIENT_ID ,client_id);
saveData(KEY_CLIENT_SECRET ,client_secret);

尝试这个

保存数据 

public void saveData(String data) {
    SharedPreferences preferences = this.getActivity().getSharedPreferences("Saved_data", Context.MODE_PRIVATE);
    SharedPreferences.Editor editor = preferences.edit();
    editor.putString("client_id",client_id).apply();
    editor.putString("client_secret",client_secret).apply();
    editor.putString("access_token",access_token).apply();
    editor.putString("refresh_token",refresh_token).apply();
}

获取数据 

    public void getSaveData() {
    SharedPreferences preferences = this.getActivity().getSharedPreferences("Saved_data", Context.MODE_PRIVATE);
    String client_id = preferences.getString("client_id", "client_id");
    String client_secret = preferences.getString("client_secret", "client_secret");
    String access_token = preferences.getString("access_token", "access_token");
    String refresh_token = preferences.getString("refresh_token", "refresh_token");
    Toast.makeText(getActivity(), client_id + " " + client_secret
            + " " + access_token + " " + refresh_token,Toast.LENGTH_SHORT).show();
}

您的保存数据是完美的，只有问题是访问方式，以及保存数据时的小变化 

editor.putString("Data", data).apply();

以下是每次通过不同密钥详细信息时传递相同密钥以检索数据的密钥。

保存令牌前请执行以下操作： 

public void saveData(String data) {
SharedPreferences preferences = 
this.getActivity().getSharedPreferences("Saved_data", 
Context.MODE_PRIVATE);
SharedPreferences.Editor editor = preferences.edit();
editor.putString("client_id", data).apply();
}

然后检索这样的数据： 

public void getSaveData() {
SharedPreferences preferences = 
this.getActivity().getSharedPreferences("Saved_data", 
 Context.MODE_PRIVATE);
String client_id = preferences.getString("client_id", null);   
Toast.makeText(getActivity(), client_id  ,Toast.LENGTH_SHORT).show();
}
