小编Dan*_*TIZ的帖子

我在android中使用Facebook登录.
码:

callbackManager = CallbackManager.Factory.create();
    LoginButton loginButton = (LoginButton) this.findViewById(R.id.login_button);
    loginButton.setReadPermissions("email", "public_profile");
    loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {
            // App code
            Log.println(Log.ASSERT, "FB", "inicio session ");
        }

        @Override
        public void onCancel() {
            Log.println(Log.ASSERT, "FB", "OP NO completada");
            // App code
        }

        @Override
        public void onError(FacebookException exception) {
            Log.println(Log.ASSERT, "FB", " Errro de sesion ");
            exception.printStackTrace();
            // App code
        }
    });

但总是收到以下错误:

SERVER_ERROR:[code] 1675030 [message]:执行查询时出错.[extra]:执行操作"ProxyAuthAppLoginQuery"时出错:在Query.proxy_auth_app_login:无法解析字段.W/System.err:

我是 NEST JS 的新手，现在我尝试在 DTO 中包含一些验证器，如下所示：

// /blog-backend/src/blog/dto/create-post.dto.ts
import { IsEmail, IsNotEmpty, IsDefined } from 'class-validator';
export class CreatePostDTO {
  @IsDefined()
  @IsNotEmpty()
  title: string;
  @IsDefined()
  @IsNotEmpty()
  description: string;
  @IsDefined()
  @IsNotEmpty()
  body: string;
  @IsEmail()
  @IsNotEmpty()
  author: string;
  @IsDefined()
  @IsNotEmpty()
  datePosted: string;
}

但是当我执行邮政服务时，例如：

{
    "title":"juanita"
}

其回报良好！但是验证器应该显示错误吗？

我的后置控制器

@Post('/post')
  async addPost(@Res() res, @Body() createPostDTO: CreatePostDTO) {
    console.log(createPostDTO)
    const newPost = await this.blogService.addPost(createPostDTO);
    return res.status(HttpStatus.OK).json({
      message: 'Post has been submitted successfully!',
      post: newPost,
    });
  }

我的 main.ts

import { NestFactory } from …

使用可可豆荚,安装firebase:

  target ‘Ejemplo’ do
pod 'MOCA'
pod 'Firebase/Auth'
end

Intall cocoa pods但是当我尝试编译时

我正在使用Python 2.7来测试以下示例:

# importando pandas, numpy y matplotlib

# importando los datasets de sklearn
from sklearn import datasets

boston = datasets.load_boston()
boston_df = pd.DataFrame(boston.data, columns=boston.feature_names)
boston_df['TARGET'] = boston.target
boston_df.head() # estructura de nuestro dataset.

from sklearn.linear_model import LinearRegression

rl = LinearRegression() # Creando el modelo.
rl.fit(boston.data, boston.target) # ajustando el modelo

# haciendo las predicciones
predicciones = rl.predict(boston.data) …

我在节点Js工作.当我试图加载文件:moviedata.json,用这行:

var allMovies = JSON.parse(fs.readFileSync('moviedata.json', 'utf8'));

显示:

错误:ENOENT:没有这样的文件或目录,在Object.fs.readFileSync(fs.js:508)的Object.fs.openSync(fs.js:640:18)的Error(native)处打开'./moviedata.json' :33)at Object.(/Users/dortiz/Documents/NodeJS/pruebas/zw/aws/MoviesLoadData.js:13:31)在Module._compile(module.js:570:32)处于Object.Module._extensions..js(module.js) :579:10)在Module.load(module.js:487:32)的tryModuleLoad(module.js:446:12)位于Module.runMain的Function.Module._load(module.js:438:3)的.js:604:10)

该文件在js的同一文件夹中读取.

但我不明白我做错了什么

嗨，我与邮递员一起制作我的json对象FCM消息：但是当我尝试发送时：

    {  
   "to":"fzvihT7dFUI:APA91bFVhnWAxXVjlWiiHIs9ZUyL1DE2hZO6GpItJtReh3hcKF1kD6mLuQq9fNP9xvS5bOFWUOG-OW-uyOedc1C43m8jfvD4OOfsBYuMbM7t1-dZEy2kQcuv3gJw6dhneVus2AR_hQHQ",
   "data":[  
      {  
         "time":1501385514224,
         "CC":"1030626890"
      }
   ],
   "notification":{  
      "body":"SPO2:95 \nPulso:75",
      "title":"El paciente Daniel Ortiz nesecita asistencia"
   }
}

响应如下：

字段“数据”必须是JSON数组：[{“ CC”：“ 1030626890”，“ time”：1501385514224}]

但我知道[{"CC":"1030626890","time":1501385514224}]它的数组，我不明白问题。我做错了什么？

我尝试在android中管理文件,但我不知道在执行中将这些文件放在哪里管理.

我可以在哪里使用prueba.html来执行此文件？
