1.在mac上，在wepy框架下使用wx.chooseImage,在success中使用tempFilePaths，圖片不顯示，代碼如下：

<img src="{{src}}" />

data = {
    src: ''
}
uploadImg() {
    let that = this;
    wx.chooseImage({
        count: 1, // 最多可以選擇的圖片張數(shù)
        sizeType: ['original', 'compressed'],
        sourceType: ['album', 'camera'], 
        success: function(res){
            that.src = res.tempFilePaths;
            console.log(that.src);
            that.$apply();
        }
    })    
}
