支付宝和银联支付是一样的
后台返回时的一个form表单如图
QQ截图20190830161851.jpg
前端需要将后台传入的表达提交即可
const div = document.createElement('div') // 创建div
div.innerHTML = res.data.html // 将返回的form 放入div
document.body.appendChild(div)
document.forms[0].submit();
微信H5支付

let _this = this;
let obj = {
pay_sn: this.payItem.pay_sn,
};
let url = encodeURI(window.location.href + '?openLayer=1')
this.$fetch(this.phpApiHost + "/mobile/index.php?act=goods_assemble&op=wxpay2_h5_launch", obj, "post", "application/json").then(res => {
if (res.code === 200) {
window.location.href = res.data.mweb_url + '&redirect_url=' + url;
} else if (res.code === 400) {
_this.$toast(res.error)
}
});
},
微信公众号支付
//后台获取支付参数
goWxPublicPay() {
console.log('goWxPublicPay')
let _this = this;

pay_sn: this.payItem.pay_sn,
openid: this.openId

this.payData=res.data
_this.callPay()
} else if (res.code === 400) {
_this.$toast(res.error)
}
});
},

//res.err_msg将在用户支付成功后返回ok,但并不保证它绝对可靠。
_this.$toast('支付成功');
