# 问题描述 #

我刚开始的`getUserProfile`的`desc`是这么写的

wx.getUserProfile({ 
    	desc: '获取你的昵称、头像、地区及性别用于信息注册',
    	success: res => { 
    		console.log(res);
    		console.log(1);
    	},
    	fail: res => { 
    		console.log(2);
    		console.log(res)
    		//拒绝授权
    		wx.showToast({ 
    			title: '您拒绝了请求,不能正常使用小程序',
    			icon: 'error',
    			duration: 2000
    		});
    		return;
    	}
    });

然后直接返回了错误信息`fail desc length does not meet the requirements`

# `大概意思是desc的长度超了` #

可以看到官网介绍

# 修改 #

`desc`改短即可

wx.getUserProfile({ 
    	desc: '获取你的昵称、头像、地区及性别',
    	success: res => { 
    		console.log(res);
    		console.log(1);
    	},
    	fail: res => { 
    		console.log(2);
    		console.log(res)
    		//拒绝授权
    		wx.showToast({ 
    			title: '您拒绝了请求,不能正常使用小程序',
    			icon: 'error',
    			duration: 2000
    		});
    		return;
    	}
    });

如果你报错`getUserProfile调用失败:fail can only be invoked by user TAP gesture.`

请看我另外一篇文章
