- 当前 Bug 的表现（可附上截图）

获取不到图片

- 预期表现

    获取到相对路径的图片

- 提供一个最简复现 Demo

js：

onLoad: function (options) {

var myCanvasWidth = 0;

var myCanvasHeight = 0;

wx.getSystemInfo({

success: function (res) {

myCanvasWidth = res.windowWidth

myCanvasHeight = res.windowHeight

},

})

this.setData({

canvasWidth: myCanvasWidth,

canvasHeight: myCanvasHeight

})

const ctx = wx.createCanvasContext('shareCanvas')

wx.getImageInfo({

src: 'blue.png',

success:function(res){

// ctx.drawImage("../../"+res.path, 0, 0, myCanvasWidth, myCanvasHeight);

// ctx.stroke();

// ctx.draw();

console.log(res);

},fail:function(res){

console.log(res);

}

})

}

wxml:

<canvas class='canvasInfo' canvas-id="shareCanvas" style='width:{{canvasWidth}}px; height:{{canvasHeight}}px;' bindlongtap="createNewImg">

</canvas>

个人测试结果：

iPhone8p、荣耀9、三星s9+ 测试均可获取到该图片资源

小米5、iPhone5（也可能是iPhone SE）获取不到
