php CURL问题

Question

本地wamp环境，配置虚拟机，demo.com。
两个控制器,想用TestA中的方法请求TestB中的方法，然后看到返回值。但是结果却不是我想要的。
哪位大神能帮我指出错误？？？不胜感激！！！

以下是代码

class TestA
{
    public function actionPost()
    {
        $url = 'dsp.com/Testb/Require_post';
        $data = array(
            'name' => 'ethan',
            'gender' => 'male',
        );
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_HEADER,1);  
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
        curl_setopt($ch, CURLOPT_POST,1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $data);      
        curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
    
        $result = curl_exec($ch); 
        curl_close($ch);      
        print_r($result);
    }
}


class TestB
{
    public function actionRequire_post()
    {
        $post = $_POST;
        print_r($post);
    }
}

以下是返回结果

Answer 1

这样写吧楼主

class TestA
{
    public function actionPost()
    {
        $url = 'dsp.com/Testb/Require_post';
        $data = array(
            'name' => 'ethan',
            'gender' => 'male',
        );
        
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
        //curl_setopt($ch, CURLOPT_POST,1);
        curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');
        
        //特别注意， 请求头设置为这样， $_POST是接收不到数据的，详情看下文
        //curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
    
        $result = curl_exec($ch); 
        curl_close($ch);      
        print_r($result);
    }
}


class TestB
{
    public function actionRequire_post()
    {
        $post = $_POST;
        print_r($post);
    }
}

你这里的Content-type 是 application/json ，服务端不会把他当做一个表单请求，也就不会去解析他。
$_POST 中的值是通过识别请求的header中的Content-type，是form-data才会去解析body中的数据，然后放到$_POST里。

还有特别不建议在写接口数据时print_r输出， 这样得到是一个string

class TestB
{
    public function actionRequire_post()
    {
        $post = $_POST;
        echo json_encode($post);
        exit;
    }
}

Answer 2

$url = 'http://dsp.com/Testb/Require_post';  试试

Answer 3

class TestA
{
    public function actionPost()
    {
        $url = 'dsp.com/Testb/Require_post';
        $data = array(
            'name' => 'ethan',
            'gender' => 'male',
        );
        $data = http_build_query($data);
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_HEADER,1);  
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
        curl_setopt($ch, CURLOPT_POST,1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $data);      
        //curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
    
        $result = curl_exec($ch); 
        curl_close($ch);      
        print_r($result);
    }
}


class TestB
{
    public function actionRequire_post()
    {
        $post = $_POST;
        print_r($post);
    }
}
