官方给的PHP解密实例associatedData，$nonceStr,$ciphertext 参数怎样获得？，具体是什么

首先可以确定的是，不是证书问题，调用图片上传接口是没问题的。 直接上代码，这是我的请求逻辑。 self::$wechatpayCertificate // 这个是微信支付平台证书 self::$wechatpaySerialNumber // 这个是微信支付平台证书序列号 $client = self::getInstance(); $encryptor = new SensitiveInfoCrypto(PemUtil::loadCertificate(self::$wechatpayCertificate)); try { // 数据上传加密处理 foreach ($data as $key => &$item) { if($key === 'business_license_info') { $item['business_license_copy'] = self::uploadImage($item['business_license_copy'])['media_id']; } if($key === 'id_card_info') { $item['id_card_copy'] = self::uploadImage($item['id_card_copy'])['media_id']; $item['id_card_national'] = self::uploadImage($item['id_card_national'])['media_id']; $item['id_card_name'] = $encryptor($item['id_card_name']); $item['id_card_number'] = $encryptor($item['id_card_number']); } if($key === 'account_info') { $item['account_name'] = $encryptor($item['account_name']); $item['account_number'] = $encryptor($item['account_number']); } if($key === 'contact_info') { $item['contact_name'] = $encryptor($item['contact_name']); $item['contact_id_card_number'] = $encryptor($item['contact_id_card_number']); $item['mobile_phone'] = $encryptor($item['mobile_phone']); $item['contact_email'] = $encryptor($item['contact_email']); } if($key === 'sales_scene_info') { if(!empty($item['store_qr_code'])) { $item['store_qr_code'] = self::uploadImage($item['store_qr_code'])['media_id']; } } if($key === 'business_addition_pics') { $newItem = []; foreach ($item as $pic) { $newItem[] = self::uploadImage($pic)['media_id']; } $item = $newItem; unset($newItem); } } // POST 语法糖 $resp = $client->post('https://api.mch.weixin.qq.com/v3/ecommerce/applyments/', [ 'json' => $data, 'headers' => [ 'Wechatpay-Serial' => self::$wechatpaySerialNumber, 'Accept' => 'application/json', ], ]);
