关于防火墙开通端口的问题?

请问内网开通访问https://api.weixin.qq.com/cgi-bin/的服务的防火墙,应该开通哪个端口?80?443?还是有其他的端口?

这不是bug，这是向下兼容，即你的手机可能不支持http2，则自动降级走http1.1

http2bug

https://developers.weixin.qq.com/miniprogram/dev/api/network/request/wx.request.html 模拟器上调试已经走http2协议，但是在真机上调试走的还是http1.1协议，且基础库的版本号已经满足2.10.4的最低版本要求 [图片]

按官方示例的云函数为啥一直超时呢？

云开发新手，按官方示例试了一下，一直报错“error message Invoking task timed out after 3 seconds; at cloud.callFunction api;” // 云函数入口文件 const cloud = require('wx-server-sdk') const got = require('got') cloud.init() // 云函数入口函数 exports.main = async (event, context) => { // console.log(event) let response = await got('https://wechat.com') return response.body } [图片] 有一个情况不知道是不是有影响，就是我们小程序现在授权给了另外一个第三方的平台，就是类似有赞的那种商城平台，配置了对方域名。但是对方有的功能不支持所以现在想着说自己开发，但是线上产品还不能停，那这种情况下是不是影响我们自己开发用小程序呢？

16130916** 这个是你故意打的星号还是说你请求时候就是星号？

获取验签密钥API报商户号无效请确认请求参数是否正确merchant invalid mch_id？

调用API：https://api.mch.weixin.qq.com/sandboxnew/pay/getsignkey 参数信息： 1、商户号为微信支付分配真实商户号 2、sign根据API密钥生成正确 3、 <xml> <mch_id>16130916**</mch_id> <nonce_str>1630740568747</nonce_str> <sign>129C2CDC27E9837B873483896858D0**</sign> </xml> <xml> <return_code><![CDATA[FAIL]]></return_code> <retmsg><![CDATA[请确认请求参数是否正确merchant invalid mch_id(16130916**)]]></retmsg> <retcode><![CDATA[1]]></retcode> </xml> 报错有些什么原因，困扰一天了。

<?php private function getEncrypt($str){     //$str是待加密字符串     $public_key_path = '平台证书路径';     $public_key = file_get_contents($public_key_path);     $encrypted = '';     openssl_public_encrypt($str,$encrypted,$public_key);     //base64编码     $sign = base64_encode($encrypted);     return $sign; } PHP官方函数文档： https://www.php.net/manual/zh/function.openssl-public-encrypt.php ，上述封装声明的padding模式即取的默认值：OPENSSL_PKCS1_PADDING ，等于文档上写的 RSAES-PKCS1-v1_5；如果一直报解密失败，可以尝试把这个padding换成APIv3的 OPENSSL_PKCS1_OAEP_PADDING 试试看，代码即： openssl_public_encrypt($str,$encrypted,$public_key, OPENSSL_PKCS1_OAEP_PADDING); 如果还不行，那就是 APIv2版的进件接口，是「半废」状态了；建议看APIv3版进件 https://pay.weixin.qq.com/wiki/doc/apiv3_partner/apis/chapter11_1_1.shtml

小微商户进件（非电商收付通）遇到：解密敏感信息失败，请检查后再试

我参考的API文档链接为： https://pay.weixin.qq.com/wiki/doc/api/xiaowei.php?chapter=19_12 https://pay.weixin.qq.com/wiki/doc/api/xiaowei.php?chapter=19_2 [图片] [图片] 代码严格按上述要求走的。 [图片] 熬到半夜都没有查出来问题。不知道怎么办了。有人能指点一下吗？自查：用一对密钥加密解密是合格的。 1，平台证书+平台序列号，没有问题。2，字段齐全。3，图片有返回。不知道是什么什么原因。。。总是报：解密敏感信息失败，请检查后再试一夜睡不着了。。。能不能来个微信支付的官方技术人员指导一下？

谢邀，content-type写错了；另外，可尝试下 wechatpay-axios-plugin 内置的 Multipart 类，完整实现了MDN的FormData协议。 https://developers.weixin.qq.com/community/develop/article/doc/0002ec32938cc0727e3cb035f56813

谢邀，`e.statusBarHeight`未获取到值，建议尝试 `wx.getSystemInfoSync`同步模式试试。

使用ColorUi，提示“Cannot set property 'StatusBar' of？

使用ColorUi，提示“Cannot set property 'StatusBar' of undefined”，我是小白，希望高手能给指导一下！谢谢！这个是在APP.JS中的。 [图片] [图片]

谢邀，你继续打 `font-` 看看提示呢？

wxss中代码自动提示为什么只显示一个？

如图，之前在wxss中[图片]只要输入一两个字母，所有包含子母的提示单词都会显示出来，为什么现在每次只显示一个呢？哪里可以设置吗？ [图片]
