/*** 更新用户昵称* @param wxUserInfo* @param token* @return*/
@RequestMapping("/updateNickName")
public R updateNickName(@RequestBody WxUserInfo wxUserInfo,@RequestHeader String token){if(StringUtil.isNotEmpty(wxUserInfo.getNickName())) {Claims claims = JwtUtils.validateJWT(token).getClaims();wxUserInfoService.update(new UpdateWrapper<WxUserInfo>().eq("openid", claims.getId()).set("nick_name", wxUserInfo.getNickName()));}return R.ok();
}

前端修改用户昵称：

<input type="nickname"  placeholder="请输入昵称" v-model="userInfo.nickName" @blur="onChangeNickName"/>

onChangeNickName:async function(e){console.log(e.detail.value);let nickName=e.detail.value;if(!isEmpty(nickName)){const result=await requestUtil({url:"/user/updateNickName",data:{nickName:nickName},method:"post"});}}

export const isEmpty=(str)=>{if(str === '' || str.trim().length === 0 ){return true}else{return false;}
}

头像上传 后端：

定义上传路径：

userImagesFilePath: D://uniapp/userImgs/

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

/*** 上传用户头像图片* @param userImage* @return* @throws Exception*/
@RequestMapping("/uploadUserImage")
public Map<String,Object> uploadUserImage(MultipartFile userImage, @RequestHeader String token)throws Exception{System.out.println("filename:"+userImage.getName());Map<String,Object> resultMap=new HashMap<>();if(!userImage.isEmpty()){// 获取文件名String originalFilename = userImage.getOriginalFilename();String suffixName=originalFilename.substring(originalFilename.lastIndexOf("."));String newFileName= DateUtil.getCurrentDateStr()+suffixName;FileUtils.copyInputStreamToFile(userImage.getInputStream(),new File(userImagesFilePath+newFileName));resultMap.put("code",0);resultMap.put("msg","上传成功");resultMap.put("userImageFileName",newFileName);// 更新到数据库UpdateWrapper<WxUserInfo> updateWrapper=new UpdateWrapper<>();Claims claims = JwtUtils.validateJWT(token).getClaims();updateWrapper.eq("openid",claims.getId()).set("avatar_url",newFileName);wxUserInfoService.update(new UpdateWrapper<WxUserInfo>().eq("openid",claims.getId()).set("avatar_url",newFileName));}return resultMap;
}

前端头像实现：

button上加下 open-type="chooseAvatar"

		onChooseAvatar:function(e){console.log(e.detail.avatarUrl)uni.uploadFile({header:{token:uni.getStorageSync("token")},url:getBaseUrl()+"/user/uploadUserImage",filePath:e.detail.avatarUrl,name:"userImage",success: (res) => {let result=JSON.parse(res.data);if(result.code==0){this.userInfo.avatarUrl=result.userImageFileName;}}})},
