开启掘金成长之旅！这是我参与「掘金日新计划 · 12 月更文挑战」的第3天，点击查看活动详情
由于在安卓端的时候选择文件时选择非媒体文件 uni.chooseFile 只适用于H5 无法在APP使用， 所以需要重新写方法 这里重新定义了安卓选择文件的方法
/**安卓文件选择*/

上面的是选择文件的方法，
下面的是使用的方法 在回调中把选中文件的本地文件路径返还回来 ， 在做上传的方法就可以了
`this.selectFile((e) => {
uni.uploadFile({ url: url, //后端的图片上传接口
filePath: tempFilePaths[0],
name: 'file',
header: { //上传需要权限校验时可在这里加上
Authorization: "Bearer " + uni.getStorageSync("token"), },
success: (uploadFileRes) => {
console.log(uploadFileRes.data);
}
});
})
