<view class="option_item" v-for="(item,index) in options" :key="item.id"><view class="option_input"><text class="removeOption" @click="removeOption(item.id)">&#xe618;</text><input type="text" v-model="item.name" placeholder="输入选项名称" placeholder-style="color:#bababa;font-size:14px"></view>				<view class="option_upload"><uni-file-picker@select="selectVoteItemFileFunc($event,index)":auto-upload="false" limit="1":del-icon="false" disable-preview file-mediatype="image" :imageStyles="voteItemImageStyles"><view class="upload"><text class="smallUploadImg">&#xe727;</text></view></uni-file-picker></view></view>

.option_item{margin-top: 10px;border-radius: 5px;background-color: white;padding: 10px;.option_input{display: flex;}.option_upload{margin-top: 20rpx;.upload{margin: 10rpx;background-color: #f4f5f7;width:90rpx;height: 90rpx;display: flex;align-items: center;justify-content: center;}}}

			voteItemImageStyles:{width:"150rpx",height:"120rpx",border:false},

selectVoteItemFileFunc:function(e,index){console.log("index="+index)console.log(e.tempFilePaths[0])uni.uploadFile({header:{token:uni.getStorageSync("token")},url:getBaseUrl()+"/vote/uploadVoteItemImage",filePath:e.tempFilePaths[0],name:"voteItemImage",success: (res) => {let result=JSON.parse(res.data);if(result.code==0){this.options[index].image=result.voteItemImageFileName;}}})},

加个image属性:

提交加上验证：

// 验证投票选项，如果有名称的，必须要上传图片for(var i=0;i<this.options.length;i++){var option=this.options[i];if(!isEmpty(option.name)){if(isEmpty(option.image)){console.log("请上传第"+(i+1)+"个投票选项图片")uni.showToast({icon:"error",title:"请上传第"+(i+1)+"个投票选项图片"})return;}}}

后端：

voteItemImagesFilePath: D://uniapp/voteItemImgs/

@Value("${voteItemImagesFilePath}")
private String voteItemImagesFilePath;

/*** 上传投票选项图片* @param voteItemImage* @return* @throws Exception*/
@RequestMapping("/uploadVoteItemImage")
public Map<String,Object> uploadVoteItemImage(MultipartFile voteItemImage)throws Exception{System.out.println("filename:"+voteItemImage.getName());Map<String,Object> resultMap=new HashMap<>();if(!voteItemImage.isEmpty()){// 获取文件名String originalFilename = voteItemImage.getOriginalFilename();String suffixName=originalFilename.substring(originalFilename.lastIndexOf("."));String newFileName= DateUtil.getCurrentDateStr()+suffixName;FileUtils.copyInputStreamToFile(voteItemImage.getInputStream(),new File(voteItemImagesFilePath+newFileName));resultMap.put("code",0);resultMap.put("msg","上传成功");resultMap.put("voteItemImageFileName",newFileName);}return resultMap;
}
