Question

我正在尝试使用cURL和PHP与anREST API进行通信。但是，我从API中遇到了一个问题，我需要能够以纯文本格式查看我的HTTP请求，我可以对其进行分析并进行更正。

我尝试了以下操作将我的请求写入文件

        $file = fopen('request.txt', 'w');
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); 
        curl_setopt($ch, CURLOPT_VERBOSE, true);    
        curl_setopt($ch, CURLOPT_STDERR, $file);

但这并没有向我显示JSON数据。

以下是我在request.txt文件中的内容

* Hostname servername was found in DNS cache
*   Trying INTERNAL IP...
* Connected to servername (INTERNAL IP) port 8018 (#0)
> PUT /icws/1163386002/messaging/subscriptions/queues/blahblah HTTP/1.1
Host: servername:8018

我希望以纯文本形式看到JSON字符串。

以下是我使用PHP

进行cURL调用的方法

private function _processRequest($method, $uri, $data = false, $header = NULL, &$httpRespond = array(), &$httpCode = NULL)
{
    $ch = curl_init();
    $url = $this->_baseURL . $uri;

    if( 
           ($method == 'POST' || $method == 'PUT') 
        && $data
    ){
        $jsonString = json_encode( $data );
        curl_setopt( $ch, CURLOPT_POSTFIELDS, $jsonString );
    }

    if($method == 'POST'){
        curl_setopt($ch, CURLOPT_POST, true);
    } elseif( $method == 'PUT'){
        //curl_setopt($ch, CURLOPT_PUT, true);
        curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PUT');
    } else {
        if ($data){
            $url = sprintf("%s?%s", $url, http_build_query($data));
        }
    }   

    //disable the use of cached connection
    curl_setopt($ch, CURLOPT_FRESH_CONNECT, true);

    //return the respond from the API
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    //return the HEADER respond from the API
    curl_setopt($ch, CURLOPT_HEADER, true);

    //add custom headers
    if(!empty($header)){
        curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
    }

    //enable SSL
    if( $this->_protocol == 'https' ){
        curl_setopt($ch, CURLOPT_CAINFO, $this->_cainfo);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, true);
    }

    //set the URL
    curl_setopt($ch, CURLOPT_URL, $url);

        $file = fopen('request.txt', 'w');
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); 
        curl_setopt($ch, CURLOPT_VERBOSE, true);    
        curl_setopt($ch, CURLOPT_STDERR, $file);        


    $respond = curl_exec($ch);

    //throw cURL exception
    if($respond === false){
        $errorNo = curl_errno($ch);
        $errorMessage = curl_error($ch);

        throw new ApiException($errorMessage, $errorNo);
    }   

    list($header, $body) = explode("\r\n\r\n", $respond, 2);

    $httpRespond = $this->_http_parse_headers($header);


    $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);  

    $result = json_decode($body, true);

    return $result;
}

如何以纯文本形式查看整个HTTP请求？

Answer 1

您可以使用Fiddler（http://www.telerik.com/fiddler）以纯文本形式查看完整的请求/响应，并测试您的REST API。

此外，您可以使用Wireshark（https://www.wireshark.org/）应用HTTP过滤器。

我的建议是Fiddler，我用它来测试和调试我的REST API。

希望这有帮助
