为啥不给二维码服务器图片地址啊
//
function getToken(){
var loadurl=“https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=”+
getApp().data.appkey.appid+"&secret="+getApp().data.appkey.secret;
wx.request({ url: loadurl,method: ‘POST’,
header: {‘content-type’: ‘application/x-www-form-urlencoded’},
data: { }
,success: function (res) {
var access_token=res.data.access_token; console.log(access_token);
getCode(access_token);
}
});
}
function getCode(access_token){
var loadurl=“https://api.weixin.qq.com/cgi-bin/wxaapp/createwxaqrcode?access_token=”+access_token;
wx.request({ url: loadurl,method: ‘POST’,
//header: {‘content-type’: ‘application/x-www-form-urlencoded’},
data: {
“path”:“pag/index/index”,
“width”:200,
},success: function (res) {//图片 二进制流
pag.setData({img_code:res.data });
console.log(“图片”+res.data.length);
//for(var p in res.data){ console.log(p + " " + res.data[p]); }
}
});
}
为啥ＪＡＶＡ得不到图片流咯，在微信模拟器里面可以的
