支付宝小程序获取用户唯一 ID的方法

以下示例由JAVA编写，请求成功后将返回user_id字段。

AlipayClient alipayClient = new DefaultAlipayClient("https://openapi.alipay.com/gateway.do","app_id","your private_key","json","GBK","alipay_public_key","RSA2");
AlipaySystemOauthTokenRequest request = new AlipaySystemOauthTokenRequest();
request.setGrantType("authorization_code");
request.setCode("4b203fe6c11548bcabd8da5bb087a83b");
request.setRefreshToken("201208134b203fe6c11548bcabd8da5bb087a83b");
AlipaySystemOauthTokenResponse response = alipayClient.execute(request);
if(response.isSuccess()){
    System.out.println("调用成功");
} else {
    System.out.println("调用失败");
}

解决方案

问题1的解决方案：
为命令添加–no-bin-links参数

yarn install --no-bin-links

问题2的解决方案：
步骤一：
修改项目根目录下的package.json，将`scripts中的内容修改为以下（删掉原内容粘贴新内容即可）：

"dev": "npm run development",
"development": "NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
"watch": "NODE_ENV=development node_modules/webpack/bin/webpack.js --watch --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
"watch-poll": "npm run watch -- --watch-poll",
"hot": "NODE_ENV=development node_modules/webpack-dev-server/bin/webpack-dev-server.js --inline --hot --config=node_modules/laravel-mix/setup/webpack.config.js",
"prod": "npm run production",
"production": "NODE_ENV=production node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js"

如图：
修改后的package.json文件

步骤二：
执行命令

npm run watch --watch-poll

此时Laravel Mix即可成功运行。
