我将使用Ruby on Rails创建restful API.我想创建,删除,显示和更新数据.所有这些都必须是JSON才能在Android设备中获得它.我也在使用Postman检查我的API.这就是我所做的:

我的控制器:

class Api::V1::UsersController < ApplicationController
    respond_to :json

    def show
        respond_with User.find(params[:id])
    end

    def create
        user=User.new(user_params)
        if user.save
            render json: user, status: 201
        else
            render json: {errors: user.errors}, status: 422
        end
    end

    def update
        user=User.find(params[:id])
        if user.update(user_params)
            render json: user, status:200
        else
        render json: {erros: user.errors},status: 422
        end

    end

    def destroy
        user=User.find(params[:id])
        user.destroy
        head 204
    end

    private
    def user_params
        params.require(:user).permit(:email,:password,:password_confirmation)
    end
end

这是我的路线档案:

Rails.application.routes.draw do
  devise_for :users
  namespace :api, defaults:{ format: :json } do
    namespace :v1 do …

我将发送Firebase云消息传递,而我遇到的问题是我收到了未经授权的错误401.

我从Firebase网站获得了安全密​​钥,然后进行了设置.设备令牌已经在数据库中,我从数据库读取没有问题.到目前为止这是我的代码:

<?php

function send_notification($tokens, $message)
{
    $url = 'https://fcm.googleapis.com/fcm/send';
    $fields = array('registration_ids' => $tokens, 'data' => $message);
    $headers = array('Authorization: key=' . "My Firebase key", 'Content-Type: application/json');
    echo "work well before init curl";
    $ch = curl_init();
    echo "init well";
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
    echo "init finishe well";
    $result = curl_exec($ch);
    echo "Execute to get result";
    if ($result === false) {
        die('Curl failed: …

我打算在Android Studio中使用rxjava进行改造。实际上我遵循了 https://code.tutsplus.com/tutorials/getting-started-with-retrofit-2--cms-27792教程这就是我所做的一切：

compile 'com.android.support:appcompat-v7:25.1.0'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    testCompile 'junit:junit:4.12'
    compile 'com.squareup.retrofit2:retrofit:2.2.0'
    compile 'com.google.code.gson:gson:2.8.0'
    compile 'com.squareup.retrofit2:converter-gson:2.2.0'
    compile 'com.android.support:recyclerview-v7:25.1.0'
    compile 'com.squareup.retrofit2:adapter-rxjava2:2.2.0'
    compile 'io.reactivex.rxjava2:rxjava:2.0.9'
    compile 'io.reactivex:rxandroid:1.2.1'
    compile 'io.reactivex.rxjava2:rxandroid:2.0.1'
    compile 'com.jakewharton.retrofit:retrofit2-rxjava2-adapter:1.0.0'

我创建了Retrofit客户端和Interface订阅方法。说不能解决

mService.getAnswer().subscribeOn(Schedulers.io()).observeOn(AndroidSchedulers.mainThread())
             .subscribe(new Subscriber<SOAnswersResponse>() {
                            @Override
                            public void onCompleted() {

                            }

                            @Override
                            public void onError(Throwable e) {

                            }

                            @Override
                            public void onNext(SOAnswersResponse soAnswersResponse) {

                            }


       }
         );
