Crie credenciais de ID do cliente OAuth para um aplicativo para computador. Para executar a amostra neste
guia, salve as credenciais como um arquivo JSON chamado credentials.json no seu
diretório local.
Para orientação, conclua as etapas de configuração do ambiente neste
guia de início rápido.
Para criar uma reação a uma mensagem, transmita o seguinte na sua
solicitação:
Especifique o escopo de autorização chat.messages.reactions.create, chat.messages.reactions ou chat.messages.
Chame o método
CreateReaction(),
transmitindo parent como o nome do recurso da mensagem a ser reagida
e reaction como uma instância de
Reaction
em que o campo unicode é um emoji padrão representado por uma string
Unicode.
O exemplo a seguir reage a uma mensagem com o emoji 😀:
import{createClientWithUserCredentials}from'./authentication-utils.js';constUSER_AUTH_OAUTH_SCOPES=['https://www.googleapis.com/auth/chat.messages.reactions.create'];// This sample shows how to create reaction to a message with user credentialasyncfunctionmain(){// Create a clientconstchatClient=awaitcreateClientWithUserCredentials(USER_AUTH_OAUTH_SCOPES);// Initialize request argument(s)constrequest={// Replace SPACE_NAME and MESSAGE_NAME here.parent:'spaces/SPACE_NAME/messages/MESSAGE_NAME',reaction:{// A standard emoji represented by a unicode string.emoji:{unicode:'😀'}}};// Make the requestconstresponse=awaitchatClient.createReaction(request);// Handle the responseconsole.log(response);}main().catch(console.error);
Para executar esta amostra, substitua o seguinte:
SPACE_NAME: o ID do
name do espaço.
Você pode conseguir o ID chamando o método
ListSpaces()
ou no URL do espaço.
MESSAGE_NAME: o ID do
name da mensagem.
É possível receber o ID do corpo da resposta retornado após a criação de uma
mensagem de forma assíncrona com a API Chat ou com o
nome personalizado
atribuído à mensagem na criação.
A API Chat retorna uma instância de
Reaction
que detalha a reação criada.
