后端代码是这样的（Python3.5.2+django1.10）

nonce_str = ''.join(random.sample('ABCDEFGHIJKLMNOPQRSTUVWXYZzyxwvutsrqponmlkjihgfedcba1234567890', random.randint(16, 32)))
order.nonce_str=nonce_str #存储nonce_str
order.save()
raw_sign = 'appid=' + settings.WXAPPID + '&body=支付测试&device_info=WEB&fee_type=CNY&mch_id=' + settings.WXMCH_ID + '&nonce_str=' + nonce_str + '¬ify_url=' + notify_url + '&openid=' + request.user.username + '&out_trade_no=' + str(order.id) + '&product_id=0001&spbill_create_ip=' + request.META['REMOTE_ADDR'] + '&total_fee=' + str(total_fee) + '&trade_type=JSAPI&key=' + settings.WXPAYKEY

return JsonResponse({'order_id':order.id,'request_json': frontreq})然后前端是先ajax请求wxpay这个接口，得到frontreq，再用frontreq去调起微信支付：（angular）
$scope.pay= function () {
/*调用微信支付模块*/
function onBridgeReady() {
console.log(obj_pay); //这个能够正常log出来！
alert(obj_pay);
WeixinJSBridge.invoke('getBrandWCPayRequest', obj_pay, function (res) {
if (res.err_msg == "get_brand_wcpay_request:ok") {
//支付成功后
//todo
alert("支付成功");
}else{
alert("支付失败，错误码为"+res.err_msg);
}
}
);
}
$http.post('/api/wxpay/',{
order_id:this.order.order_id
}).then(function (response) {
alert("wait_123");
//定义全局变量obj_pay
// console.log(response.data.request_json);
obj_pay=response.data.request_json;
orderid=response.data.order_id;
//调用微信内置的支付模块
if (typeof WeixinJSBridge == "undefined" ) {
if (document.addEventListener) {
document.addEventListener('WeixinJSBridgeReady', onBridgeReady, false);
} else if (document.attachEvent) {
document.attachEvent('WeixinJSBridgeReady', onBridgeReady);
document.attachEvent('onWeixinJSBridgeReady', onBridgeReady);
}
} else {
onBridgeReady();
}
}, function () {
alert("支付失败");
});
}
});其中，在onBridgeReady函数中log出来的obj_pay是这样的：
感觉并没有哪里写错啊。。求指点
谢谢
python
打印一下微信的同步响应信息 一看就知道了
