1.微信支付注意事項:
{"code":-100,"message":"[payment微信:-1]General errors"}
以上錯誤碼-100是5+SDK的錯誤碼，而-1爲微信支付SDK的錯誤碼，對應的微信的錯誤類型爲：簽名錯誤、未註冊APPID、項目設置APPID不正確、註冊的APPID與設置的不匹配、其他異常等。
根據錯誤提示我們逐步排除。
登記的包名或簽名錯誤
覈對微信後臺登記的應用包名以及應用簽名是否有誤，登記的簽名需要和簽名工具獲取到的一致，更新這些信息並非馬上生效，可以等一段時間再測試。另外需要確保應用已經通過審覈，並獲得支付權限。
APPID錯誤
覈對項目中manifest.json文件中填寫的微信支付的AppID是否和平臺上的一致。
付款信息計算錯誤
覈對後端代碼，查驗統一下單和調起支付接口的邏輯是否有誤，並確保兩次簽名生成算法一致。
H5+接口調用錯誤
接口plus.payment.request調用時傳入的支付信息是字符串類型，如:官方返回數據地址是:
http://demo.dcloud.net.cn/payment/wxpayv3.HBuilder/?total=1 返回數據如下是個json_encode的數組
{"appid":"wx0411fa6a39d61297","noncestr":"5v5efv7JKmDGv91X","package":"Sign=WXPay","partnerid":"1230636401","prepayid":"wx28170035285029c12927cdc40885888318","timestamp":1545987635,"sign":"56A6442588EB590F57EF48F2EC104DE9"}
微信支付 測試一定要打包,並且簽名才能調起來的!!!!!!!!!!!
