使用imgSecCheck, msgSecCheck这两个API的时候碰到一些雷,现在就分享下. msgSecCheck传输的文本不可以是Unicode编码,要进行解码后再传输, 否则返回的是 "内容正常,无违规内容" PHP DEMO: private function scantxt($url, $data) {     $curl = curl_init();     curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);     curl_setopt($curl, CURLOPT_TIMEOUT, 500);     curl_setopt($curl, CURLOPT_POST, 1);     curl_setopt($curl, CURLOPT_POSTFIELDS, $data);     curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, true);     curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 2);     curl_setopt($curl, CURLOPT_URL, $url);     $res = curl_exec($curl);     curl_close($curl);     return $res; } 调用: $data = ['content' => 'xxxxxxxxxxxxxxxxxxxxxxx']; scantxt($url, json_encode($data, JSON_UNESCAPED_UNICODE)); imgSecCheckmedia参数类型为form-data, 应该是指POST表单的头格式为 Content-Type: multipart/form-data 其实就是服务器端模拟文件上传功能,上传文件给微信服务器, 被上传的文件不支持URL,只能为本地图片,图片路径推荐绝对路径(只要能根据路径找到该文件即可,有的可以相对路径) PHP 5.5以上和以下使用的API方法不同 其实微信可以考虑支持BASE64,这样更简便.     5. API文章最下方的@, 其实可加可不加, 不加的时候微信也鉴别( @意思是上传的为图片)     private function upimg($url)     {             $file = __DIR__ . '/123.jpg';             $cfile = curl_file_create($file, 'image/jpg', '@testpic'); //这里硬编码了,自己修改             $imgdata = array('media' => $cfile);             $curl = curl_init();             curl_setopt($curl, CURLOPT_URL, $url);             curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-Type: multipart/form-data'));             curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, true); // stop verifying certificate             curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 2);             curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);             curl_setopt($curl, CURLOPT_POST, 1);             curl_setopt($curl, CURLOPT_POSTFIELDS, $imgdata);             $r = curl_exec($curl);             curl_close($curl);             return $r;     }
