微信base64图片显示问题

js

/**

   * 加载图片

   */

  onLoadImage:function(){

    var that = this;

  

    wx.request({

      url: that.data.httpUrl+'findImgDataByOne.do',

      method:'GET',

      responseType: 'arraybuffer',

      success:function(res){

        if(res.statusCode==200){

          console.log("",res.data);

          var imageData =res.data;

          imageData = wx.arrayBufferToBase64(imageData);

          that.setData({

            //

            proImage:'data:image/jpg;base64,'+imageData

          });

          console.log(that.data.proImage);

        }

      }

    })

 

wxml

 

  <image src="{{proImage?proImage:'../../../images/xc_img.png'}}"></image>

 

 

java后端：

@RequestMapping(value="/findImgDataByOne",method=RequestMethod.GET)
@ResponseBody
public byte[] findImgDataByOne(String barCode){
byte[] obj = wxOrderSerivice.findImgDataByOne(barCode);
return obj;
}
