需要边手动替换为真实的服务器和文件路径，比如说 internal://cache/xxx.txt，这里对应的是haps/entry/cache。

import request from ‘@ohos.request’; 
import { BusinessError } from ‘@ohos.base’; 
 
@Entry 
@Component 
struct Page { 
  @State message: string = ‘Hello World’; 
 
  build() { 
    Row() { 
      Column() { 
        Text(this.message) 
          .fontSize(50) 
          .fontWeight(FontWeight.Bold) 
        Button(‘上传’).onClick(() => { 
          let uploadTask: request.UploadTask; 
          let uploadConfig: request.UploadConfig = { 
            url: ‘http://www.example.com’, //需要手动替换为真实服务器地址 
            header: { ‘Accept’: ‘/’ }, 
            method: “POST”, 
            files: [{ filename: “test”, name: “test”, uri: “internal://cache/test.jpg”, type: “jpg” }], 
            data: [{ name: “name123”, value: “123” }], 
          }; 
          try { 
            request.uploadFile(getContext(), uploadConfig, (err: BusinessError, data: request.UploadTask) => { 
              let headerCallback = (headers: object) => { 
                console.info(“upOnHeader headers:” + JSON.stringify(headers)); 
              }; 
              uploadTask.on(‘headerReceive’, headerCallback); 
              if (err) { 
                console.error(Failed to request the upload. Code: ${err.code}, message: ${err.message}); 
                return; 
              } 
              uploadTask = data; 
 
            }); 
          } catch (err) { 
            console.error(Failed to request the upload. err: ${JSON.stringify(err)}); 
          } 
 
        }) 
      } 
      .width(‘100%’) 
    } 
    .height(‘100%’) 
  } 
}
