}，

console.log(obj);

uni.requestPayment({

provider: 'wxpay',

orderInfo: obj,

success: function(res) {

console.log('success:' + JSON.stringify(res));

},

fail: function(err) {

console.log('fail:' + JSON.stringify(err));

uni.hideLoading()

}

});

直接进入fail，打印的日志：fail:{"errMsg":"requestPayment:fail errors"}，一直无法唤起微信
