Angular Fire Storage 不使用模拟器

问题描述 投票：0回答：1

在我的 Ionic Angular 应用程序中，我将使用 firebase 进行存储和身份验证。

我建立了一个非常基本的项目，并尝试让所有 Firebase 模拟器正常工作。 按照 firebase 指示运行所有命令并安装 Angular Fire 后，除了存储模拟器之外，我的所有模拟器都工作正常。存储模拟器似乎没有正确连接，因为生产存储桶用于所有内容。

我多次检查了端口并尝试了连接模拟器的不同方法，但似乎没有任何效果

这些是我的文件

import { FirebaseApp } from '@angular/fire/app';
import { getBlob, ref } from '@angular/fire/storage';
import { getStorage } from 'firebase/storage';

@Injectable({
  providedIn: 'root'
})
export class StorageService {
  private storageReference: string = "my-reference";
  private storage = getStorage(this.app);

  constructor(private app: FirebaseApp) {}

  downloadImage(dirRef: string) {
    return getBlob(ref(this.storage, `${this.storageReference}/${dirRef}/image1.jpg`))
        .then(image => {
            var urlCreator = window.URL || window.webkitURL;
        return urlCreator.createObjectURL(image);
    })
  }
}

我找到了解决该问题的方法。 在我的 

storage.service.ts
的构造函数中，我添加了这一行：

if (!environment.production) connectStorageEmulator(this.storage, 'localhost', 9199);

现在可以使用模拟器了。不过，我更喜欢位于 

app.module.ts
文件中的解决方案。

我已经尝试像这样提供存储空间，但也没有成功：

    provideStorage(() => {
      const storage = getStorage();
      if (!environment.production) connectStorageEmulator(storage, 'localhost', 9199);
      return storage;
    })

如果有人能帮助我，我会很高兴:)

在您的 

storage.service.ts
上，不要使用 
getStorage
来检索存储实例，而是使用 
Storage
类并注入到您的服务中。

存储服务应该是这样的。

import { Injectable } from '@angular/core';
import { getBlob, ref, Storage } from '@angular/fire/storage';

@Injectable({
  providedIn: 'root'
})
export class StorageService {
  private storageReference: string = "my-reference";

  // changes
  constructor(private storage: Storage) {}

  downloadImage(dirRef: string) {
    return getBlob(ref(this.storage, `${this.storageReference}/${dirRef}/image1.jpg`))
        .then(image => {
            var urlCreator = window.URL || window.webkitURL;
        return urlCreator.createObjectURL(image);
    })
  }
}

或者像这样

import { Injectable, inject } from '@angular/core';
import { getBlob, ref, Storage } from '@angular/fire/storage';

@Injectable({
  providedIn: 'root'
})
export class StorageService {
  private storageReference: string = "my-reference";

  // changes
  private storage = inject(Storage);

  downloadImage(dirRef: string) {
    return getBlob(ref(this.storage, `${this.storageReference}/${dirRef}/image1.jpg`))
        .then(image => {
            var urlCreator = window.URL || window.webkitURL;
        return urlCreator.createObjectURL(image);
    })
  }
}

这样它将使用 

app.module.ts
文件中的配置。
