使用Antd上传操作将图像上传到Firebase存储时出现问题 [英] Issues while uploading an image to firebase storage with Antd upload action

问题描述

我正在使用antd 图片墙/卡使用此参考代码以及我要更改的唯一位置将图像上传到Firebase存储的示例是<Upload>组件上的action属性.

I'm using antd picture-wall/card example to upload images to my firebase storage with this reference code and the only place I'm changing is action property on <Upload> component.

在action属性上，我正在使用一个函数，将图像上载到Firebase存储中，而不是链接两者都可以接受，如在文档中看到的.

On the action property, I'm using a function that uploads the images to firebase storage instead of a link both are accepted as seen in docs.

我的动作函数如下:

export async function uploadImage(file) {
    const storage = firebase.storage()
    const metadata = {
        contentType: 'image/jpeg'
    }
    const storageRef = await storage.ref()
    const imageName = generateHashName() //a unique name for the image
    const imgFile = storageRef.child(`Vince Wear/${imageName}.png`)
    return imgFile.put(file, metadata)
}

问题来了，图像已成功上传到Firebase，但是我不断收到蚂蚁般的响应处理错误，并且可能无法确定action函数应返回的内容，即使在文档中也写到了它应该返回一个诺言.

Issue comes, The image uploads to firebase successfully, but I keep getting antd response handling errors and possibly not sure what action function should return, even though, is written in the docs that it should return a promise.

错误消息:

XML Parsing Error: syntax error
Location: http://localhost:3000/[object%20Object]
Line Number 1, Column 1:

错误也会在上传的图像缩略图上显示为红色边框.

Errors also appear as a red border on the uploaded image thumbnail.

请求的帮助，我的操作功能应该返回什么以消除错误.我可以解析我的Firebase响应，并将必要的详细信息返回给antd上传操作.

Requested help, What should my action function return to get rid of errors. I can parse my firebase response and return the necessary details to antd upload action.

使用

    "antd": "^3.9.2",
    "firebase": "^5.8.5",
    "react": "^16.7.0",

推荐答案

您可以使用customRequest属性来解决此问题.看看

You can use customRequest prop to fix this issue. Have a look

class CustomUpload extends Component {
  state = { loading: false, imageUrl: '' };
  
  handleChange = (info) => {
    if (info.file.status === 'uploading') {
      this.setState({ loading: true });
      return;
    }
    if (info.file.status === 'done') {
      getBase64(info.file.originFileObj, imageUrl => this.setState({
        imageUrl,
        loading: false
      }));
    }
  };

  beforeUpload = (file) => {
    const isImage = file.type.indexOf('image/') === 0;
    if (!isImage) {
      AntMessage.error('You can only upload image file!');
    }
    
    // You can remove this validation if you want
    const isLt5M = file.size / 1024 / 1024 < 5;
    if (!isLt5M) {
      AntMessage.error('Image must smaller than 5MB!');
    }
    return isImage && isLt5M;
  };

  customUpload = ({ onError, onSuccess, file }) => {
    const storage = firebase.storage();
    const metadata = {
        contentType: 'image/jpeg'
    }
    const storageRef = await storage.ref();
    const imageName = generateHashName(); //a unique name for the image
    const imgFile = storageRef.child(`Vince Wear/${imageName}.png`);
    try {
      const image = await imgFile.put(file, metadata);
      onSuccess(null, image);
    } catch(e) {
      onError(e);
    }
  };
  
  render () {
    const { loading, imageUrl } = this.state;
    const uploadButton = (
    <div>
      <Icon type={loading ? 'loading' : 'plus'} />
      <div className="ant-upload-text">Upload</div>
    </div>
    );
    return (
      <div>
        <Upload
          name="avatar"
          listType="picture-card"
          className="avatar-uploader"
          beforeUpload={this.beforeUpload}
          onChange={this.handleChange}
          customRequest={this.customUpload}
        >
          {imageUrl ? <img src={imageUrl} alt="avatar" /> : uploadButton}
        </Upload>
      </div>
    );
  }
}
