错误信息： {"code""PARAM_ERROR","message""请确认待处理的消息是否为加密后的密文"} 看到特约商户更新了文档之后，我采用的是最新的API-v3接口规则 请求头如下（证书序列号是微信支付平台序列号）： array("Content-Type: application/json","Accept:application/json","User-Agent:".$_SERVER['HTTP_USER_AGENT'],"Authorization:"$this->authorization,"Wechatpay-Serial:"$this->cert_sn) 验签如下(验签使用的是商户平台私钥)： $url_parts = parse_url($url）; $canonical_url = ($url_parts['path'] . (!empty($url_parts['query'])) ? "?${url_parts['query']}" : "")); $message = strtoupper($http_method).'\n'.canonical_url.'\n'. $timestamp.'\n'. $nonce.'\n'. $body.'\n'; $pri_key_string = file_get_contents($this->apiclient_key); $pri_key = openssl_get_privatekey($pri_key_string); if(!openssl_sign(message, raw_sign, pri_key, 'sha256WithRSAEncryption')){ throw new WxPayException('make sign failed:'.PHP_EOL); } $sign = base64_encode($raw_sign); 加密敏感信息(使用微信支付平台公钥)： $pub_key_string = file_get_contents($this->cert_path); $pub_key = openssl_get_publickey($pub_key_string); $encrypted = ''; if(openssl_public_encrypt($str,$encrypted,$pub_key,OPENSSL_PKCS1_OAEP_PADDING)){ return base64_encode($encrypted); } 麻烦看一下是什么问题，官方给的错误信息没有明确指出是哪个字段加密出错，现在找不到处理的办法了。

啥也没做，就被微信限制了提款权限。只能收钱不能提现？ [图片]

如何使用这个sdk上传图片。我是用如下代码，无法通过验签 $wechatPayMiddleware = WechatPayMiddleware::builder() ->withMerchant(CommonData::MCH_ID, CommonData::SERIAL_NUMBER, CommonData::getPrivateKey()) ->withWechatPay([ CommonData::getCertificate() ]) // 可传入多个微信支付平台证书，参数类型为array ->withValidator(new NoValidator()) ->build(); // 将WechatPayMiddleware添加到Guzzle的HandlerStack中 $stack = HandlerStack::create(); $stack->push($wechatPayMiddleware, 'wechatpay'); // 创建Guzzle HTTP Client时，将HandlerStack传入 $client = new \GuzzleHttp\Client(['handler' => $stack, 'verify' => false]); $url = 'https://xxx.com/'.$object; // 接下来，正常使用Guzzle发起API请求，WechatPayMiddleware会自动地处理签名和验签 $resp = $client->request('POST', CommonData::URL . $this->getUri(), [ 'headers' => [ 'Accept' => 'application/json' ], 'multipart' => [ [ 'name'=>'file', 'contents'=>fopen($url, 'r') ], [ 'name'=>'meta', 'contents'=>json_encode([ 'filename'=>basename($url), 'sha256'=>hash('sha256', (new Oss())->downloadFile('hic-image', $object)), ]) ] ], ]); $result = json_decode($resp->getBody()->getContents(), true);
