快速实现一个真正的免费个人免签支付

今年利用业余时间搞了个web应用，在支付环节卡住了，因为支付宝和微信都不支持个人收款，必须要有公司资质，没办法，只能google下看看是否有人和我遇到相同问题，果然有很多解决方案，研究了一个多礼拜，发现个人收款都是收费的，而且还不稳定，服务也非常差，问个问题半天甚至几天后才有回答。最后没办法只能自己各种研究，搞出了一种真正免费的个人免签支付方案（不需了解Andriod，不需了解后端开发，甚至不需要写一行代码），不敢独享，现分享给大家。

基本原理

终极原理很简单，就一句话：Android端应用将收到的个人微信的收款信息通知后端服务，后端服务分析出谁支付了多少钱等信息，然后通知开发者支付完成并自动发货。

操作流程

1. 开发者上传微信的个人收款码到平台。

2. 用户发起请求支付服务。

3. 平台返回相匹配的收款二维码并展示给用户。

4. 用户完成扫码支付。

5. 安装有收款微信的Android手机收到用户完成支付的通知。

6. Android端应用将收款信息通知后端服务。

7. 后端服务分析并校验无误后，通知开发者用户已经完成支付，可以自动发货了。

下面介绍利用「冰狐智能辅助」实现免费的个人免签支付的方案,您只需要详细案以下步骤操作，不需要写一行代码即可实现免费的个人免签支付。分两部分实现，一部分是移动端，负责捕获收款信息；另一部分是后端服务，负责解析并通知开发者支付结果。在之前请先免费注册一个用户。

构建移动端

下载「冰狐智能辅助」APP并安装，安装完成后请登录。登录时请按提示打开所有权限，具体下载地址和详细安装配置过程请参考这里。
登录网页，打开web页面「移动端」/「移动端脚本」，新建一个名为“个人支付”的脚本，将如下JS脚本粘贴到这里并保存。

function main() {while (true) {}
}function cbNotification(textList, className, packageName, event) {for (var item of textList) {if (item.includes('微信支付')) {var arr = item.fetchNumber();if (arr.length > 0) {var ret = callMicroService('pay_notify', [rsUUID, 1, arr[arr.length - 1]]);console.log('call ret:' + ret);}return true;}}return false;
}

打开web页面「移动端」/「我的设备」，找到刚才登录的手机，然后选择“编辑”按钮，修改“默认脚本”为上面新建的“个人支付”脚本。

创建微服务脚本

微服务脚本用于实现后端的业务逻辑，比如：上传和查看支付二维码，查看支付订单，通知开发者支付结果等功能。

打开web页面「微服务」/「微服务脚本」新建如下脚本，并将对应的JS源码粘贴进去：

pay_notify，用于处理支付信息，并通知开发者支付结果。JS源码如下：

function main(uuid, type, price) {var ret = false;price = parseInt(price*100);var key = uuid + price;var orderId = cacheGet(key);if (orderId) {console.log('匹配到价格，可以通知了:' + orderId);var data = dbQuery('order', '*', ['id=' + orderId]);if (data && data.length == 1) {var item = data[0];// 通知 调用者var bodyParams = {outTradeNo: item.outTradeNo, price: item.price / 100.0, realPrice: item.realPrice / 100.0};var result = 2, postResult = httpPost(item.notifyUrl, bodyParams);if (postResult && postResult.length > 0) {if (postResult.status == 200 || postResult.status == 302) {result = 1;}}// change statusret = dbUpdate('order', ['status=' + result], ['id=' + orderId]);if (!ret) {console.error('更新状态失败');}cacheRemove(key);}} else {console.error('invalidate price:' + price);}return ret;
}

add_price，用于添加支付二维码，JS源码如下：

function main(payType, price, deviceId, file) {price = parseInt(price*100);var ret = false, qrCode = qrDecode(file.inputStream);if (qrCode != '') {var qRet = dbQuery('price', 'count(id) as count', [`userId='${rsOpenId}'`, `price=${price}`, `payType=${payType}`, `deviceId='${deviceId}'`]);if (qRet[0].count > 0) {ret = dbUpdate('price', [`qrCode='${qrCode}'`], [`price=${price}`, `payType=${payType}`, `deviceId='${deviceId}'`]);} else {var iRet = dbInsert('price', {userId:rsOpenId, price:price, payType:payType, deviceId:deviceId, qrCode:qrCode});ret = iRet > 0;}}return ret;
}

query_price，用于查询支付二维码，JS源码如下：

function main(fetchCountOnly, conditions, startIndex, itemCount) {var jsonConditions = JSON.parse(conditions), params = [`userId='${rsOpenId}'`];for (var item of jsonConditions) {if (item.name == 'query_type') {var type = parseInt(item.value);if (type > 0) {params.push('payType=' + type);}}}if (fetchCountOnly) {var qRet = dbQuery('price', 'count(id) as count', params);return qRet[0].count;} else {var qRet = dbQuery('price', '*', params, '', startIndex, itemCount);for (var item of qRet) {item.price /= 100.0;if (item.payType == 1) {item.payType = '微信';} else {item.payType = '支付宝';}}return qRet;}
}

query_order，用于查询订单，JS源码如下：

function main(fetchCountOnly, conditions, startIndex, itemCount) {var jsonConditions = JSON.parse(conditions);var params = [`userId='${rsOpenId}'`];for (var item of jsonConditions) {var deviceId = item.value;if (item.name == 'deviceId' && deviceId != '') {params.push(`deviceId='${deviceId}'`);}}if (fetchCountOnly) {var qRet = dbQuery('order', 'count(id) as count', params);return qRet[0].count;} else {var qRet = dbQuery('order', '*', params, 'order by time desc', startIndex, itemCount);for (var item of qRet) {item.price /= 100.0;item.realPrice /= 100.0;if (item.payType == 1) {item.payType = '微信';} else {item.payType = '支付宝';}if (item.status == 0) {item.status = '等待支付';} else if (item.status == 1) {item.status = '交易完成';} else if (item.status == 2) {item.status = '通知失败';} else if (item.status == -1) {item.status = '订单过期';}var datetime = new Date();datetime.setTime(item.time);var year = datetime.getYear();var month = datetime.getMonth() + 1 < 10 ? "0" + (datetime.getMonth() + 1) : datetime.getMonth() + 1;var date = datetime.getDate() < 10 ? "0" + datetime.getDate() : datetime.getDate();var hour = datetime.getHours()< 10 ? "0" + datetime.getHours() : datetime.getHours();var minute = datetime.getMinutes()< 10 ? "0" + datetime.getMinutes() : datetime.getMinutes();var second = datetime.getSeconds()< 10 ? "0" + datetime.getSeconds() : datetime.getSeconds();var t = year + "-" + month + "-" + date+" "+hour+":"+minute+":"+second;item.time = t;}return qRet;}
}

unified_order，用于开发者请求支付，返回支付二维码，JS源码如下：

function main(payType, price, outTradeNo, notifyUrl, timeout = 120000) {price = parseInt(price*100);var ret = null, qrImage = '', realPrice = price;var maxCount = 5, i = 0, anyRet = null, findAny = false;while (i < maxCount) {realPrice = price - i;var qRet = dbQuery('price', '*', [`userId='${rsOpenId}'`, `payType=${payType}`, `price=${realPrice}`]);if (qRet.length <= 0) {if (!findAny) {anyRet = dbQuery('price', '*', [`userId='${rsOpenId}'`, `payType=${payType}`, 'price=0']);findAny = true;}qRet = anyRet;}if (qRet.length > 0) {for (var item of qRet) {var key = item.deviceId + realPrice;var cache = cacheGet(key);if (null == cache) {lock('malloc_price');cache = cacheGet(key);if (null == cache) {// 可以分配了ret = dbInsert('order', {userId: rsOpenId,price: price,realPrice: realPrice,outTradeNo: outTradeNo,deviceId: item.deviceId,qrCode: item.qrCode,notifyUrl: notifyUrl});}if (null != ret) {var image = qrEncode(item.qrCode);qrImage = base64Encode(image);cachePut(key, ret, 60000);}unlock('malloc_price');if (null != ret) {break;}}}}if (null != ret) {break;}++i;}if (null == ret) {console.error('unified failed');} else {return {payTye: payType, price: price, realPrice: realPrice, qrImageData: qrImage, timeout: timeout};}return {};
}

common，一些通用的函数，JS源码如下：

function deletePrice(item) {var id = item.id;return dbDelete('price', [`id=${id}`]);
}function deleteOrder(item) {var id = item.id;return dbDelete('order', [`id=${id}`]);
}function getDevice(includeAll=false) {var list =  deviceList(rsOpenId);var result = [];if (includeAll) {result.push({name: '全部', value: ''});}for (var item of list) {result.push({name: item.name, value: item.uuid});}return result;
}

创建移动端接口

移动端接口用于「冰狐智能辅助」APP端脚本调用，在这里主要用于手机端通知后端服务支付相关信息。参考文档

打开web页面「微服务」/「移动端接口」，新建名为“pay_notify”的接口，选择“pay_notify”脚本。

创建服务端接口

查看unified_order脚本的入口参数可知，接口参数为：[payType, price, outTradeNo, notifyUrl]，依次为：支付类型(微信:1,支付宝:2)，支付价格，交易序列号，和支付成功后的通知url

启动手机端程序

打开手机端「冰狐智能辅助」APP，点击“点击这里启动设备”启动设备。

上传微信支付二维码

打开web页面「微服务」/「数据查询服务」，找到“查询价格”服务，然后点击“查询“按钮查询已经上传的价格二维码。

支付测试

用postman模拟第三方后端服务调用接口，生成订单。
https://aznfz.com/api/call_micro_service?clientKey=xxxxx&accessToken=yyyyy&name=unified_order&isDev=true&params=zzz，注意：params必须encodeUriComponent否则无法成功，下图中[1, 0.5, 'xxxxxxxx1', 'https://baidu.com']为原始参数，%5B1%2C%200.5%2C%20'xxxxxxxx1'%2C%20'https%3A%2F%2Fbaidu.com'%5D为encodeUriComponent后的参数（在params行点击右键选择“encodeUriComponent”）。详细请参考文档：冰狐智能辅助
调用后就生成了对应的支付订单，可在「微服务」/「数据查询服务」，“订单查询”服务中，点击“查询”按钮查询订单。

用其他微信向收款微信支付一笔费用，完成后，再次查询订单，看看是否完成。

总结

本文介绍了一种基于「冰狐智能辅助」系统实现的、不需了解Andriod、不需了解后端开发、甚至不需要编写一行代码、免费的、个人免签支付方案和具体实现细节。有任何问题，欢迎评论留言，大家一起讨论
