PHP微信開發-access-token的獲取與存儲

存儲是以.txt的方式存儲token值的 先上代碼

1. <?php

2.  

3. require_once("file_cache.php");

4. class WeixinUtil{

5. private $appId = 'appId ';

6. private $appSecret = 'appSecret ';

7. //獲取AccessToken

8. public function getAccessToken(){

9. $wx_access_token_cache_key = 'wx_access_token';

10.  

11. $cache = new FileCache('./access_token.txt');//存儲的本地位置

12. $token = $cache->get($wx_access_token_cache_key);//去文件中獲取token

13.  

14. if (!$token){//沒有的話就創建新的

15. $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=".$this->appId."&secret=".$this->appSecret;

16. $token = $this->https_curl_json($url,null);

17. $cache->set($wx_access_token_cache_key, $token, time()+7000);

18. }

19.  

20. $token = json_decode($token);

21. $token = $token->access_token;

22. return $token;

23. }

24.  

25. /* 發送json格式的數據，到api接口*/

26. public function https_curl_json($url,$data){

27. $headers = array("Content-type: application/json;charset=UTF-8","Accept: application/json","Cache-Control: no-cache", "Pragma: no-cache");

28. $curl = curl_init();

29. curl_setopt($curl, CURLOPT_URL, $url);

30. curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);

31. curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);

32. if (!empty($data)){

33. curl_setopt($curl, CURLOPT_POST, 1);

34. curl_setopt($curl, CURLOPT_POSTFIELDS,$data);

35. }

36. curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);

37. curl_setopt($curl, CURLOPT_HTTPHEADER, $headers );

38. $output = curl_exec($curl);

39. if (curl_errno($curl)) {

40. echo 'Errno'.curl_error($curl);//捕抓異常

41. }

42. curl_close($curl);

43. return $output;

44. }

45.  

46. }

47. ?>

另一個類 用來進行文件操作

1. <?php

2. //該類用來配合WeixinUtil.php類 進行token的文件操作

3. class FileCache{

4. private $cache_file;

5.  

6. private function load(){

7. if(file_exists($this->cache_file)){

8. $content = file_get_contents($this->cache_file);

9. if (strlen($content) > 0){

10. $data = json_decode($content);

11. return $data;

12. }

13. }

14. return array();

15. }

16.  

17. private function save($data){

18. $content = json_encode($data);

19. return file_put_contents($this->cache_file, $content);

20. }

21.  

22. public function __construct($filename) {

23. $this->cache_file = $filename;

24. }

25.  

26. public function get($key){

27. $data = $this->load();

28.  

29. foreach($data as $item){

30. if ($item->key == $key){

31. if ($item->expire_time > time()){

32. return $item->value;

33. }

34. break;

35. }

36. }

37. return NULL;

38. }

39.  

40. public function set($key, $value, $expire_time=NULL){

41. $data = $this->load();

42. $obj = NULL;

43. foreach($data as $item){

44. if ($item->key == $key){

45. $obj = $item;

46. $obj->value = $value;

47. if ($expire_time != NULL){

48. $obj->expire_time = $expire_time;

49. }

50. break;

51. }

52. }

53.  

54. if ($obj == NULL){

55. $obj = new CacheItem($key, $value, $expire_time);

56. array_push($data, $obj);

57. }

58. return $this->save($data);

59. }

60. }

61.  

62. class CacheItem{

63. public $key;

64. public $value;

65. public $expire_time;

66.  

67. public function __construct($key, $value, $expire_time) {

68. $this->key = $key;

69. $this->value = $value;

70. $this->expire_time = $expire_time;

71. }

72. }

73. ?>

最後 測試類

1. <?php

2. include "WeixinUtil.php";

3. $wx = new WeixinUtil();

4. echo $wx->getAccessToken();
