我正在尝试使用 Apollo Server 的Upload标量将文件直接发送到 S3。我的架构：

const { gql } = require('apollo-server-express')

module.exports = gql`

extend type Mutation {
  createPicture(
    name: String!
    picture: Upload!
  ): Picture!
}

type Picture {
  name: String!
  picture: String!
}
`

解析器：

const { combineResolvers } = require('graphql-resolvers')
const isAuthenticated = require('./auth')
const { uploadPhoto } = require('../services/picture')

module.exports = {
  Mutation: {
    createPicture: combineResolvers(
      isAuthenticated,
      async (
        parent,
        { name, picture = null },
        { models, me }
      ) => {
        const { …

我得到_tkinter.TclError: couldn't connect to display "localhost:10.0"SSH'ing时（含-X）到我的Ubuntu 16.04服务器，运行此脚本

from os import path
from wordcloud import WordCloud
import matplotlib as mpl
import matplotlib.pyplot as plt

mpl.use('Agg')
d = path.dirname(__file__)

text = open(path.join(d, 'words.txt')).read()
wordcloud = WordCloud().generate(text)

# Configure plot
plt.imshow(wordcloud, interpolation='bilinear')
plt.axis("off")

# lower max_font_size
wordcloud = WordCloud(max_font_size=40).generate(text)
plt.figure()
plt.imshow(wordcloud, interpolation="bilinear")
plt.axis("off")

plt.savefig("comments.png")

此脚本使用 Wordcloud ( https://github.com/amueller/word_cloud/ )。words.txt是一堆我打算变成词云的词。应该发生的事情是云被保存为comments.png（但未显示）在我正在连接的服务器上。

我有一个BeforeInsertandAfterInsert钩子没有被调用。它所做的只是记录hook。我正在使用 Nestjs-graphql。

您可以运行此示例npm i，然后发送一个突变（playground 位于localhost:3000/graphql)body 处createUser(createInput:{password:"password" email:"test@test.com"})。它应该成功并记录hook。

钩子（没有记录任何内容）：

@Entity('user')
export default class UserEntity {

    @PrimaryGeneratedColumn()
    id: number;

    @Column()
    @IsEmail()
    email: string;

    @Column()
    @Length(7, 42)
    password: string;

    @BeforeInsert()
    @AfterInsert()
    async validate() {
        console.log("hook")
    }
}

它是从服务中调用的。插入不会引发错误，并here2会被记录：

@Injectable()
export class UserService {
    constructor(
        @InjectRepository(UserEntity)
        private readonly userRepository: Repository<UserEntity>,
    ) { }

    async createNew(email: string, password: string): Promise<number> {
        console.log("here2")
        const hashedPassword = …
