php - cURL 通过命令行工作，但不能在 PHP Curl 中工作

Question

以下命令在命令行中运行完美:

c:\>curl -v -H "Content-Type: text/xml" -d "<?xml version='1.0' encoding='utf-8'?><methodCall><methodName>create_account</methodName><params><param><value><struct><member><name>user</name><value><string>test</string></value></member><member><name>server</name><value><string>chat3.activengage.com</string></value></member><member><name>password</name><value><string>test</string></value></member></struct></value></param></params></methodCall>" http://localhost:4561
* About to connect() to localhost port 4561 (#0)
*   Trying 127.0.0.1...
* connected
* Connected to localhost (127.0.0.1) port 4561 (#0)
> POST / HTTP/1.1
> User-Agent: curl/7.26.0
> Host: localhost:4561
> Accept: */*
> Content-Type: text/xml
> Content-Length: 428
>
* upload completely sent off: 428 out of 428 bytes
< HTTP/1.1 200 OK
< Content-Length: 113
< Server: Erlang/Process-One
< Connection: close
<
<?xml version="1.0"?><methodResponse><params><param><value><int>0</int></value><
/param></params></methodResponse>* Closing connection #0

在 PHP 中使用下面的代码:

public /*string*/ function registerUser(/*string*/$user,/*string*/$pass){
        $xml = "<?xml version='1.0' encoding='utf-8'?><methodCall><methodName>create_account</methodName><params><param><value><struct><member><name>user</name><value><string>test2</string></value></member><member><name>server</name><value><string>chat3.activengage.com</string></value></member><member><name>password</name><value><string>test</string></value></member></struct></value></param></params></methodCall>";
        $handle = curl_init();
        curl_setopt($handle, CURLOPT_URL, 'http://127.0.0.1:4561');
        curl_setopt($handle, CURLOPT_VERBOSE, 1);
            curl_setopt($handle, CURLOPT_HTTPHEADER, array('Content-Type: text/xml'));
        curl_setopt($handle, CURLOPT_POST, 1);
        curl_setopt($handle, CURLOPT_RETURNTRANSFER, 1);
            curl_setopt($handle, CURLOPT_POSTFIELDS, $xml);
        $content = curl_exec($handle);
        echo $xml;
        $httpCode = curl_getinfo($handle, CURLINFO_HTTP_CODE);
        print_r($httpCode);
        print_r($content);
        if(curl_errno($handle))
        {
         echo 'error:' . curl_error($handle);
        }
        curl_close($handle);
}

结果是 HTTP 状态代码 400。我做错了什么吗？

更新 - CURLINFO_HEADER_OUT 的结果

string(99) "POST / HTTP/1.1
Host: localhost:4561
Accept: */*
Content-Type: text/xml
Content-Length: 400

"

Answer 1

在我破坏 etc/resolv.conf 文件后，从基于浏览器的 PHP 脚本运行 curl 请求失败。

参观后发现

php5-curl error: couldn't resolve host

修复resolve.conf文件后如下:(注意:192.168.1.1是我的路由器地址)

# Generated by NetworkManager
nameserver 192.168.1.1

Curl 的行为符合预期。

希望对你有帮助
