const upload = async() upload 是什么

这段代码中的 `upload` 是一个异步函数（async function），其功能可能是上传文件或数据到服务器或其他存储设备。由于函数定义中使用了 `async` 关键字，因此该函数会返回一个 Promise 对象。在函数内部，可能会使用异步操作，如网络请求或文件读写等，通过 `await` 关键字等待异步操作的完成后再返回结果。

富文本编辑器 配置 uploadAttachment: { // 自定义上传附件 async customUpload(file: File, insertFn: any) { try { const formData = new FormData(); formData.append('file', file); fetchApi(uploadImgFile, { param: formData, onRequestSuccessfull: (ret: any) => { const url = fileSever + ret?.result?.name; const alt = ret?.result?.originalName; const href = fileSever + ret?.result?.name; insertFn(url, alt || '', href || ''); }, }); } catch (error) { console.log(error); } }, }, 还会报错没有配置上传地址

根据您提供的代码，您的上传附件插件配置似乎没有包含`uploadUrl`字段，这可能是报错“没有配置上传地址”的原因。请将您的上传附件插件配置中添加`uploadUrl`字段，并将其设置为您后端的上传接口地址，例如：

uploadAttachment: {
  // 自定义上传附件
  async customUpload(file: File, insertFn: any) {
    try {
      const formData = new FormData();
      formData.append('file', file);
      fetchApi(uploadImgFile, {
        param: formData,
        onRequestSuccessfull: (ret: any) => {
          const url = fileSever + ret?.result?.name;
          const alt = ret?.result?.originalName;
          const href = fileSever + ret?.result?.name;
          insertFn(url, alt || '', href || '');
        },
      });
    } catch (error) {
      console.log(error);
    }
  },
  // 添加uploadUrl字段
  uploadUrl: 'your-upload-url',
},

请将`your-upload-url`替换为您后端的上传接口地址。希望这个解决方案能够帮助您解决问题。

async function createBlobFromLocalPath( containerClient: ContainerClient, blobName: string, uploadFile:Blob, uploadOptions: BlockBlobParallelUploadOptions ): Promise<void> { // create blob client from container client const blockBlobClient = await containerClient.getBlockBlobClient(`${blobName}/${uploadFile.name}`); // upload file to blob storage const uploadResult = await blockBlobClient.uploadStream( uploadFile, {} ); console.log(uploadResult) if (!uploadResult.errorCode) { console.log(`${blobName} succeeded ${uploadResult.date}`); return } console.log(uploadResult) } 提示类型“Blob”的参数不能赋给类型“Readable”的参数。 类型“Blob”缺少类型“Readable”的以下属性: readableAborted, readable, readableDidRead, readableEncoding 及其他 37 项。

这段代码中的问题是，`uploadFile` 参数的类型为 `Blob`，但是 `uploadStream` 方法需要传入一个 `Readable` 类型的参数。这两个类型并不兼容，因此会出现类型错误。需要将 `uploadFile` 转换为 `Readable` 类型，可以使用 `stream.Readable.from` 方法来实现。修改后的代码如下：

import * as stream from 'stream';

async function createBlobFromLocalPath(
  containerClient: ContainerClient,
  blobName: string,
  uploadFile: Blob,
  uploadOptions: BlockBlobParallelUploadOptions
): Promise<void> {
  // create blob client from container client
  const blockBlobClient = await containerClient.getBlockBlobClient(`${blobName}/${uploadFile.name}`);

  // convert Blob to Readable stream
  const readableStream = stream.Readable.from(uploadFile);

  // upload file to blob storage
  const uploadResult = await blockBlobClient.uploadStream(
    readableStream,
    {},
    uploadOptions
  );

  console.log(uploadResult);

  if (!uploadResult.errorCode) {
    console.log(`${blobName} succeeded ${uploadResult.date}`);
    return;
  }

  console.log(uploadResult);
}
