Question

规定─＆GT;

使用GET请求获取对象列表：

传递请求标头：

X-ACCESS-TOKEN =成功登录后收到的令牌

X-USER-EMAIL =登录时使用的电子邮件。

我正在使用此代码登录 - ＆gt;

private void normalLoginToServer() {
    final ProgressDialog progressDialog = GeneralUtil.createProgressDialog(this, "Logging into app..");
    progressDialog.show();

Instead of using JSONObject, i need to pass Request Headers.
in a below Astrike code. how to pass Headers.? please help me.

    ***JSONObject outer_body = new JSONObject();
    JSONObject body = new JSONObject();
    try {
        body.put(Constants.USER_EMAIL, _emailText.getText().toString().trim());
        body.put(Constants.USER_PWD, _passwordText.getText().toString().trim());

        outer_body.put(Constants.USER, body);***

        try {
            TypedInput typedInput = new TypedByteArray("text/plain", outer_body.toString().getBytes("UTF-8"));

            apiService.loginToServer(typedInput, new Callback<UserInfo>() {
                @Override
                public void success(UserInfo response, Response response2) {
                    int status = response2.getStatus();
                    switch (status) {
                        case 200:
                            if (progressDialog.isShowing())
                                progressDialog.dismiss();
                            if (response == null)

Answer 1

您可以在改装api界面中使用@Header。例如，像：

void loginToServer(@Header("your_header") String yourHeaderValue, Callback<UserInfo> callback);

Answer 2

假设您想要传递静态标头（那些为单个请求赢得更改的人）。例如，此代码将缓存控制标头添加到/ tasks请求

public interface UserService {  
    @Headers("Cache-Control: max-age=640000")
    @GET("/tasks")
    List<Task> getTasks();
}

如果您需要传递动态标头（那些更改个别请求）

public interface UserService {  
    @GET("/tasks")
    List<Task> getTasks(@Header("Content-Range") String contentRange);
}
