php_curl+执行不成功,php类 方法里调用curl（）,不成功

class Qq_api {

private $list;

function __construct() {

$this->list['dsp_id'] = DSP_ID;

$this->list['token'] = TOKEN;

}

function curl_post($end = '') {

$ch = curl_init(URL.$end);

curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

}

function sync() {

$this->curl_post('sync');

$arr = array();

curl_setopt($ch, CURLOPT_POSTFIELDS,$arr);

$result = curl_exec($ch);

var_dump($result);

}

}

提示：Warning: curl_setopt(): supplied argument is not a valid cURL handle resource in C:AppServwwwqq_api2.php on line 45

我是在方法里调用curl()，好像curl()只能在_construct()里面初始化吧，如果是为什么？

回复内容：

class Qq_api {

private $list;

function __construct() {

$this->list['dsp_id'] = DSP_ID;

$this->list['token'] = TOKEN;

}

function curl_post($end = '') {

$ch = curl_init(URL.$end);

curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

}

function sync() {

$this->curl_post('sync');

$arr = array();

curl_setopt($ch, CURLOPT_POSTFIELDS,$arr);

$result = curl_exec($ch);

var_dump($result);

}

}

不好意思，封贴.乱试试出来了。

在类里的方法声明的变量$ch是局部的，把所有$ch地方改成$this->ch就行了

function curl_post($end = '') {

$this->ch = curl_init(URL.$end);

curl_setopt($this->ch, CURLOPT_CUSTOMREQUEST, 'POST');

curl_setopt($this->ch, CURLOPT_SSL_VERIFYPEER, false);

curl_setopt($this->ch, CURLOPT_SSL_VERIFYHOST, false);

curl_setopt($this->ch, CURLOPT_RETURNTRANSFER, true);

}
