使用react-native-image-picker将图片上传到firebase [英] Upload image to firebase using react-native-image-picker

问题描述

我一直在尝试使用firebase，React Native和react-native-image-picker来上传图片。

我从图片选择器获得的数据是在base64格式，我不知道如何实际上传到我的firebase存储，因为当我执行以下行：

  var imageRef = storageRef.child（images / usersImages /+ global.userID +.jpg）
 uploadTask = imageRef.put（global.imageToUpload）
  

之后没有执行任何操作。即使我之后立即发出警报。
我的«file»变量包含：'data：image / jpeg; base64，'+ response.data

我也试着只放入response.data，但是不起作用。

解决方案

从我上次阅读这里，Firebase不支持从 react-native 作为二进制文件上传图片。但是，您可以将base64编码的图像直接存储在firebase中。这就像将任何其他字符串存储在firebase中一样。尽管像这样直接在firebase上存储图像，但是小于10 MB 的限制。

I’ve been trying to upload an image using firebase, React Native and react-native-image-picker.

The data I get from the image picker is in base64 format and I don’t know how to actually upload it to my firebase storage because when I execute the following line :

var imageRef = storageRef.child("images/usersImages/" + global.userID + ".jpg")
uploadTask = imageRef.put(global.imageToUpload)

Nothing is executed after. Even if I put an alert right after. My « file » variable contains that : 'data:image/jpeg;base64,' + response.data

I’ve also tried to put only the response.data but it’s not working.

解决方案

From what I read last here, Firebase doesn't support uploading images as binaries from react-native. However, you can store the base64 encoded image directly in firebase. It would be like storing any other string in firebase. There is a limit of less than 10 MB though while storing image directly on firebase like this.
