先建立一個html，並以json格式傳輸到php檔案
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>身份證識別</title> <style> </style> <script> window.onload = function(){ var input = document.getElementById("demo_input"); var result= document.getElementById("result"); var img_area = document.getElementById("img_area"); if ( typeof(FileReader) === 'undefined' ){ result.innerHTML = "抱歉，你的瀏覽器不支援 FileReader，請使用現代瀏覽器操作！"; input.setAttribute('disabled','disabled'); }else{ input.addEventListener('change',readFile,false); } } function readFile(){ var file = this.files[0]; //這裡我們判斷下類型如果不是圖片就返回 去掉就可以上傳任意檔案 if(!/image\/\w+/.test(file.type)){ alert("請確保檔案為映像類型"); return false; } var reader = new FileReader(); reader.readAsDataURL(file); console.log(); reader.onload = function(e){ result.innerHTML = this.result; img_area.innerHTML = '<p class="sitetip">圖片img標籤展示：</p><img src="'+this.result+'" alt=""/>'; } } </script> </head><body> <form action="upload.php" method="post"> <input type="file" value="sdgsdg" id="demo_input" /> <textarea style='display: none;' name="img" id="result" rows=30 cols=300></textarea> <p id="img_area"></p> <input type="submit" value="提交"></form></body> </html>
再建立個upload.php
<?phpheader("Content-Type: text/html; charset=UTF-8");/** * base64圖片上傳 * @param $base64_img * @return array */$base64_img = trim($_POST['img']);$up_dir = 'upload/';//存放在目前的目錄的upload檔案夾下$fi_dir = 'ok_upload/';//存放在目前的目錄的upload檔案夾下if(!file_exists($up_dir)){ mkdir($up_dir,0777);}if(preg_match('/^(data:\s*image\/(\w+);base64,)/', $base64_img, $result)){ $type = $result[2]; if(in_array($type,array('pjpeg','jpeg','jpg','gif','bmp','png'))){ $new_file = $up_dir.date('YmdHis_').'.'.$type; if(file_put_contents($new_file, base64_decode(str_replace($result[1], '', $base64_img)))){ $img_path = str_replace('../../..', '', $new_file);$path = 'upload/';$data = file_get_contents($img_path);$base64 = base64_encode($data);$appkey = 'LzJu1grfwH6UaDX2';$params = array( 'app_id' => '1106920947', 'image' => $base64, 'card_type' => '0', 'time_stamp' => strval(time()), 'nonce_str' => strval(rand()), 'sign' => '',);$params['sign'] = getReqSign($params, $appkey);// 執行API調用$url = 'https://api.ai.qq.com/fcgi-bin/ocr/ocr_idcardocr';//身份證識別OCR$response = doHttpPost($url, $params); echo $response;die;$arr = json_decode($response,true);$photo = base64_decode($arr['data']['image']);if(!file_exists($fi_dir)){ mkdir($fi_dir,0777);}$type = 'jpg'; if(in_array($type,array('pjpeg','jpeg','jpg','gif','bmp','png'))){ $new_file = $fi_dir.date('YmdHis_').'.'.$type; if(file_put_contents($new_file, str_replace($result[1], '', $photo))){ $img_paths = str_replace('../../..', '', $new_file); echo '圖片處理成功</br><img src="' .$img_paths. '">'; }else{ echo '圖片處理失敗</br>'; } } }else{ echo '圖片上傳失敗</br>'; } }else{ //檔案類型錯誤 echo '圖片上傳類型錯誤'; }}else{ //檔案錯誤 echo '檔案錯誤';}
// getReqSign ：根據 介面請求參數 和 應用密鑰 計算 請求籤名// 參數說明// - $params：介面請求參數（特別注意：不同的介面，參數對一般不一樣，請以具體介面要求為準）// - $appkey：應用密鑰// 返回資料// - 簽名結果function getReqSign($params /* 關聯陣列 */, $appkey /* 字串*/){ // 1. 字典升序排序 ksort($params); // 2. 拼按URL索引值對 $str = ''; foreach ($params as $key => $value) { if ($value !== '') { $str .= $key . '=' . urlencode($value) . '&'; } } // 3. 拼接app_key $str .= 'app_key=' . $appkey; // 4. MD5運算+轉換大寫，得到請求籤名 $sign = strtoupper(md5($str)); return $sign;}
// doHttpPost ：執行POST請求，並取迴響應結果// 參數說明// - $url ：介面請求地址// - $params：完整介面請求參數（特別注意：不同的介面，參數對一般不一樣，請以具體介面要求為準）// 返回資料// - 返回false表示失敗，否則表示API成功返回的HTTP BODY部分function doHttpPost($url, $params){ $curl = curl_init(); $response = false; do { // 1. 設定HTTP URL (API地址) curl_setopt($curl, CURLOPT_URL, $url); // 2. 設定HTTP HEADER (表單POST) $head = array( 'Content-Type: application/x-www-form-urlencoded' ); curl_setopt($curl, CURLOPT_HTTPHEADER, $head); // 3. 設定HTTP BODY (URL索引值對) $body = http_build_query($params); curl_setopt($curl, CURLOPT_POST, true); curl_setopt($curl, CURLOPT_POSTFIELDS, $body); // 4. 調用API，擷取響應結果 curl_setopt($curl, CURLOPT_HEADER, false); curl_setopt($curl, CURLOPT_NOBODY, false); curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, true); curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); $response = curl_exec($curl); if ($response === false) { $response = false; break; } $code = curl_getinfo($curl, CURLINFO_HTTP_CODE); if ($code != 200) { $response = false; break; } } while (0); curl_close($curl); return $response;}
這樣就能識別身份證上的資訊了
