},fail: function () {
// fail
},complete: function () {
// complete
}
})
},这是是调用上传头像uploadFile方法
// 上传头像
app.uploadimg({
url: 'URL地址',path: avatar,header: {
'Content-Type': 'multipart/form-data',"Authorization": "Bearer " + token
},isShow: false
});

上传头像代码uploadFile做了一个封装 代码放在APP.js里
//多张图片上传
uploadimg:function(data){
var that= this,i=data.i ? data.i : 0,success=data.success ? data.success : 0,fail=data.fail ? data.fail : 0;
wx.uploadFile({
url: data.url,filePath: data.path[i],name: 'fileData',//这里根据自己的实际情况改
header: data.header,formData: {
sequence:i+1
},success: (resp) => {
success++;
console.log(resp)
console.log(i+"成功");

}

},fail: (res) => {
fail++;
console.log('fail:' + i + "fail:" + fail);
},complete: () => {
console.log(i);
i++;
if (i == data.path.length) { //当图片传完时，停止调用
console.log('执行完毕');
console.log('成功：' + success + " 失败：" + fail);

} else {//若图片还没有传完，则继续调用函数
console.log(i);
data.i = i;
data.success = success;
data.fail = fail;
that.uploadimg(data);
}

}
});
},
