实现比较简单，文档中都有描述，就是第一次做可能会有疏漏，记录一下：

<view class="edict-item" @click="selectPic"><text class="item-name" :style="$em.$getThemeStyle(['avatarConText'])">头像</text><image class="icon-head" :src="headSrc" mode="aspectFill"></image><image class="item-arrow" src="@/static/icon_editinfo_arrow_right.png" mode="heightFix"></image>
</view>

selectPic() {let that = this;uni.chooseImage({count: 1, //默认9sizeType: ['original', 'compressed'], //可以指定是原图还是压缩图，默认二者都有sourceType: ['album'], //从相册选择success: function(res) {that.headSrc = res.tempFilePaths[0]that.saveAvatar(that.headSrc)}});},saveAvatar(url){let header = {'Content-Type': 'application/json'}// 获取本地token  此处 有例外 不需要token的请求 后续添加console.log('当前请求token====' + loginUtil.getToken())if (loginUtil.getToken()) {header['Authorization'] = 'Bearer ' + loginUtil.getToken();}uni.uploadFile({url: 'https://smarteye-app-uat.gwm.cn/prod-api/system/user/profile/avatar', //仅为示例，非真实的接口地址filePath: url,name: 'file',header:header,// success: (res) => {// 	console.log('save', res);// }});},
