該文僅對(duì)于中間這種支付方式有參考價(jià)值喲
一敢伸、開發(fā)背景
在微信公眾號(hào)中，需要進(jìn)行微信支付且為微信公眾號(hào)網(wǎng)頁支付。
二悲柱、準(zhǔn)備工作
1.申請(qǐng)商戶平臺(tái)
step1. 登錄公眾平臺(tái)，點(diǎn)擊左側(cè)菜單中的微信支付些己，如圖豌鸡，
step2. 進(jìn)入支付申請(qǐng)，按照指引填寫相關(guān)的信息并提交段标；
step3. 資料審核通過后涯冠，支付寶會(huì)向登記的銀行帳號(hào)打一筆款，收到款后逼庞，兩次登錄到公眾平臺(tái)填寫正確的數(shù)字蛇更，簽約成功，如圖赛糟，
注意：在申請(qǐng)支付功能的時(shí)候派任，不要申請(qǐng)成了服務(wù)商，需要的是商戶璧南。雖然服務(wù)商也具備支付功能掌逛，但在調(diào)用 接口時(shí)會(huì)比商戶復(fù)雜一點(diǎn)，申請(qǐng)過程也繁瑣一點(diǎn)司倚。另外服務(wù)商和商戶是具備不同的業(yè)務(wù)功能的豆混，常見的微商場(chǎng)用的更多是商戶平臺(tái)。對(duì)于服務(wù)商和商戶的區(qū)別我理解的是动知，服務(wù)商是對(duì)商戶提供技術(shù)支持的第三方團(tuán)隊(duì)皿伺。
finally , ?通過各種審核后，支付寶會(huì)向你的郵箱發(fā)送以下信息盒粮，保存好鸵鸥，在調(diào)用接口時(shí)會(huì)用到
2.配置支付參數(shù)
如下圖，進(jìn)入公眾平臺(tái)-微信支付-開發(fā)配置拆讯，設(shè)置支付授權(quán)目錄及支付回調(diào)脂男。
如果配置的是測(cè)試目錄則還需要添加測(cè)試微信號(hào)進(jìn)入測(cè)試白名單养叛；
支付授權(quán)目錄的要求：
1、所有使用公眾號(hào)支付方式發(fā)起支付請(qǐng)求的鏈接地址宰翅，都必須在支付授權(quán)目錄之下弃甥；
2、最多設(shè)置3個(gè)支付授權(quán)目錄汁讼，且域名必須通過ICP備案淆攻；
3、頭部要包含http或https嘿架，須細(xì)化到二級(jí)或三級(jí)目錄瓶珊，以左斜杠“/”結(jié)尾。
支付回調(diào)URl：頭部要包括http或https耸彪，當(dāng)公眾平臺(tái)接到掃碼支付請(qǐng)求時(shí)伞芹，會(huì)回調(diào)此URL傳遞訂單信息。
這里指的是支付成功后蝉娜，支付寶服務(wù)器會(huì)直接調(diào)用商戶系統(tǒng)的服務(wù)器對(duì)訂單進(jìn)行處理唱较，比如修改狀態(tài)等，用戶是無感知的召川，可以當(dāng)作一個(gè)方法南缓，該方法中不支付session. 如果需要傳遞參數(shù)怎么辦了，tell you later.
二荧呐、調(diào)用接口步驟
1）獲取用戶授權(quán)(獲取openid, 獲取方式可以參考微信公眾號(hào)網(wǎng)頁授權(quán))
2）調(diào)用統(tǒng)一下單接口獲取預(yù)支付id(prepay_id)
3）H5調(diào)起微信支付的內(nèi)置JS
4）支付完成后汉形，微信回調(diào)URL的處理
看文字覺得麻煩的同志請(qǐng)參考以下稍顯形象的手繪圖，
step1. 獲取用戶授權(quán)
參考?微信公眾號(hào)網(wǎng)頁授權(quán)summer版
step2. 獲取Prepay_id
根據(jù)文檔(https://pay.weixin.qq.com/wiki/doc/api/jsapi.php?chapter=9_1)要求倍阐，將傳遞的參數(shù)拼接成要求的xml格式到請(qǐng)求地址：https://api.mch.weixin.qq.com/pay/unifiedorder概疆，獲得prepay_id.
如果連圖也懶得看的同志直接copy 代碼吧，貼到eclipse慢慢暈收捣，每個(gè)參數(shù)的意義都已經(jīng)加以說明
highlight的參數(shù)注意一下届案，容易被坑。
在加密時(shí)還要注意變量key罢艾。這里提個(gè)問楣颠，整個(gè)過程中加密多少次？
String sign = PayCommonUtils.createSign("UTF-8",packageParams);
key設(shè)置路徑：微信商戶平臺(tái)(pay.weixin.qq.com)-->賬戶設(shè)置-->API安全-->密鑰設(shè)置

return finalpackage;
}
step3. 網(wǎng)頁端調(diào)起支付api
將上一步取得的prepay_id存到package中，在微信js接口中將以下參數(shù)傳遞罗晕。
$('.btn-info').click(function () {
if ("1" == mPaymentType) {? ? ? //微信支付
$.ajax({
type: "post",
dataType: "json",
url: contextPath + "/order/order_payment_wechat.html",
data: {
mPaymentType: mPaymentType,
companyId: companyId,
},
}).done(function (response) {
console.log(response);
if (!isNull(response.errorCode)) {
alert(errorCode);
return false;
}
var obj = response.data;
WeixinJSBridge.invoke('getBrandWCPayRequest', {
"appId": obj.appId,? ? ? ? ? ? ? ? ? //公眾號(hào)名稱济欢，由商戶傳入
"timeStamp": obj.timeStamp,? ? ? ? ? //時(shí)間戳
"nonceStr": obj.nonceStr,? ? ? ? //隨機(jī)串
"package": obj.package,? ? ? //商品包信息
"signType": obj.signType,? ? ? ? //微信簽名方式:
"paySign": obj.paySign? ? ? //微信簽名
}, function (res) {
if (res.err_msg == "get_brand_wcpay_request:ok") {
alert('支付成功!');
} else if (res.err_msg == "get_brand_wcpay_request:cancel") {
alert("支付取消");
} else {
alert("支付失敗!");
}
});
});
}
js調(diào)用接口時(shí)會(huì)將微信支付窗口拉起，
支付成功會(huì)跳轉(zhuǎn)到如圖頁面小渊，點(diǎn)擊完成頁面會(huì)返回到回調(diào)函數(shù)中,
if (res.err_msg == "get_brand_wcpay_request:ok") {
alert('支付成功!');
}
在js調(diào)用過程中法褥，還是遇到一些錯(cuò)誤，不要驚慌酬屉，將錯(cuò)誤提示alert出來半等，或者在微信web開發(fā)者工具中console.log()出，方便調(diào)錯(cuò)
step4:處理支付返回值?
支付成功后梆惯，支付寶會(huì)調(diào)用之前配置的回調(diào)函數(shù)酱鸭，我們只需要用response去接受
/**

三烁登、測(cè)試

因?yàn)槲⑿沤涌趯?duì)客戶端有一些限制锨络，所有搭建測(cè)試環(huán)境有點(diǎn)費(fèi)時(shí)，可以參考微信公眾號(hào)網(wǎng)頁授權(quán)summer版
四狼牺、工具類共享

在html中調(diào)用微信js接口時(shí)蛮穿，我對(duì)官方提供的寫法很沒信心庶骄，心想沒有引入任何js文件怎么可能引用到方法，抱著試一試的想法践磅，呀单刁，居然有反映。置疑和相信都存在時(shí)音诈，帶著置疑大膽去try try try...at last , you'll trust the truth幻碱，哈哈哈...。另外细溅，在測(cè)試過程中時(shí)常會(huì)遇到一些偶發(fā)的bug, 從最初的小僥幸到現(xiàn)在的事出必有因不知放掉了多少bug,現(xiàn)在明白選擇相信科學(xué)錯(cuò)出來也不會(huì)太離譜褥傍。
