小程序上传图片时,对应的uploadFile接口一次只能上传一张,这里选择后台提供一个专门上传图片的接口上传图片后返回链接,再调用比如说评论接口,将返回的图片链接带上后,再一起上传。
uploadImg (pictures) { if (pictures.length) { const initNum = pictures.length let succNum = 0 //统计上传图片成功的数量 const token = Taro.getStorageSync(\'token\') pictures.map((pic: any) => { Taro.uploadFile({ url: \'upload_img\', filePath: pic.url, name: \'img\', header: { \'Authentication\': token, }, }).then((res: any) => { if (res.data.status === \'SUCC\') { let uploadImgs: string[] = this.state.uploadImgs uploadImgs.push(res.data.imgurl) this.setState({ uploadImgs, }, () => { succNum += 1 if (initNum === succNum) {
// 调用评论上传方法 this.httpComment()
} }) } else { $toast(\'上传图片失败,请重试!\') return false } }) }) } }
