uniapp v3+ts 使用 u-upload上传图片以及视频

上传图片方法 


// maxCount 最大上传数

 const fileList1 = ref([]);
    const file = ref([])
    // 删除图片
    const deletePic = (event : any) => {
        fileList1.value.splice(event.index, 1);
        file.value.splice(event.index, 1);
        // console.log(fileList1.value); file
    };

    // 新增图片
    const afterRead = async (event : any) => {
        // 当设置 mutiple 为 true 时, file 为数组格式,否则为对象格式
        let lists = [].concat(event.file);
        let fileListLen = fileList1.value.length;
        lists.map((item) => {
            fileList1.value.push({
                ...item,
                status: 'uploading',
                message: '上传中',
            });
        });
        for (let i = 0; i < lists.length; i++) {
            const result = await uploadFilePromise(lists[i].url);
            let item = fileList1.value[fileListLen];
            fileList1.value.splice(fileListLen, 1, {
                ...item,
                status: 'success',
                message: '',
                url: result,
            });
            fileListLen++;
        }
    };

    const uploadFilePromise = (url : any) => {
        return new Promise((resolve, reject) => {
            let a = uni.uploadFile({
                url: import.meta.env.VITE_APP_BASE_URL + 'file/image', // 图片上传地址
                filePath: url,
                name: 'file',
                header: {
                    "site-id": import.meta.env.VITE_SITE_ID,
                    "token": getToken()
                },
                formData: {

                },
                success: (res) => {
                    let respic = JSON.parse(res.data)
                    console.log(respic.data.url, '图片');
                    let obj = respic.data.url
                    file.value.push(obj)
                    setTimeout(() => {
                        resolve(res.data.data);
                    }, 1000);
                },
            });
        });
    };

上传视频 方法

 



  const videoFileList = ref([])
    const videoAfterRead = async (event : any) => {
        let lists = [].concat(event.file);
        let fileListLen = videoFileList.value.length;
        lists.map((item) => {
            videoFileList.value.push({
                ...item,
                status: 'uploading',
                message: '上传中',
            });
        });
        for (let i = 0; i < lists.length; i++) {
            const result = await uploadVideoFile(lists[i].url);
            let item = videoFileList.value[fileListLen];
            videoFileList.value.splice(fileListLen, 1, {
                ...item,
                status: 'success',
                message: '',
                url: result,
            });
            fileListLen++;
        }
    };
    const videoValue = ref('')
    const uploadVideoFile = (url : any) => {
        return new Promise((resolve, reject) => {
            let a = uni.uploadFile({
                // 后端上传视频地址
                url: import.meta.env.VITE_APP_BASE_URL + 'file/video', // 视频上传地址
                filePath: url,
                name: 'file',
                // header 携带内容 根据自己后端要求
                header: {
                    "site-id": import.meta.env.VITE_SITE_ID,
                    "token": getToken()
                },
                success: (res) => {
                    res.data = JSON.parse(res.data)
                    // console.log(res.data, '测试');
                    videoValue.value = res.data.data.url
                    
                    // console.log(videoValue.value, '测试');
                    // 这个状态值要根据后端接口返的 若对不上 则视频不会回显,一直显示上传中
                    if (res.data.code == 1) {
                        setTimeout(() => {
                            resolve(res.data.url)
                        }, 1000)
                    }
                },
                fail: (error) => {
                    console.log(error, '上次失败的原因');
                    uni.showToast({
                        title: '上传失败',
                        icon: 'none'
                    });
                    reject(error)
                }
            });
        });
    };

 const deleteVideo = (event : any) => {
        videoFileList.value.splice(event.index, 1);
        videoValue.value = '';
    }

点击提交时 要传递视频 跟图片的地址值

const submit = () => {
      
        let params = {
            images: file.value,
            video: videoValue.value
        }
        console.log(params, '发布的参数');
       // 执行自己的请求 todo
    }
