tdesign的文件上傳功能實(shí)現(xiàn)(微信小程序+idea的springboot)
更新時(shí)間：2023年09月21日 09:27:40 作者：素心如月椏
這篇文章主要介紹了tdesign的文件上傳(微信小程序+idea的springboot)的相關(guān)知識(shí)，本文通過圖文實(shí)例代碼相結(jié)合給大家介紹的非常詳細(xì)，對(duì)大家的學(xué)習(xí)或工作具有一定的參考借鑒價(jià)值，需要的朋友參考下吧
1. springboot后端
1.1 FileController.java
如上圖可以看到，微信小程序的請(qǐng)求url要傳來一個(gè)type值，
controller全部代碼如下，直接復(fù)制粘貼就行：

@RestController
public class FileController extends BaseController {
@Resource
private IFileService fileService;
@RequestMapping(value = "/files/{type}", method = RequestMethod.POST)
public String uploadFile(@PathVariable String type ,HttpServletRequest request) throws Exception {
return fileService.uploadFiles(request, type);
}

2.1 TDesign的upload組件
TDesign的upload組件 (tencent.com)
https://tdesign.tencent.com/miniprogram/components/upload
1. app.json全局引用一下
2. wxml
如圖可以看到mediaType中我只保留了模版中的image，bind:add事件我定義了一個(gè)handleCertificateAdd()，用于上傳我的房屋產(chǎn)權(quán)圖片，max修改為0，可以上傳任意個(gè)圖片
3. js
js頁(yè)面主要修改了
1. data的數(shù)據(jù)：
定義一個(gè)數(shù)組 `certificateList:[ ]`就行
2. 【重點(diǎn)！】uploadFile(file,updateProgress,updateSuccess)方法
token
這個(gè)token就是數(shù)據(jù)庫(kù)中的token的值
3. handleCertificateAdd()方法
遍歷上傳的所有圖片，通過調(diào)用上面的uploadFile方法
下面來分析這幾個(gè)紅框中的代碼
1.
this.setData({
certificateList: [...(this.data.certificateList), {
...file,
status: 'loading'
}],
});
2.
每個(gè)file都遍歷調(diào)用uploadFile(file,updateProgress,updateSuccess)方法實(shí)現(xiàn)上傳，
把方法體作為參數(shù)，回調(diào)，
方框中的方法，是uploadFile(file,updateProgress,updateSuccess)中的updateProgress參數(shù)
可以看到task的返回值參數(shù)res.progress為100
3.
(ue) => {
console.log('certificateList:' + ue)
this.setData({
[`certificateList[${length}].status`]: 'done',
[`certificateList[${length}].remoteUrl`]: ue.data
});
}如下圖 方框中的方法，就是作為uploadFile(file,updateProgress,updateSuccess)中的updateSuccess參數(shù)
[`certificateList[${length}].status`]: 'done'就是把圖片的status屬性設(shè)置為done，圖片顯示出來不會(huì)一直轉(zhuǎn)圈
