使用 PHP curl 下载 github 存储库时遇到问题

Question

根据标题，我正在尝试使用 php curl 库从 github 下载一个 repo。这是我的代码：

        $url = 'https://api.github.com/repos/SeanPeterson/Raspberry-Pi-Case/zipball/master';
        $curl = curl_init();
        curl_setopt($curl, CURLOPT_HEADER, 1);
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($curl, CURLOPT_BINARYTRANSFER, 1);
        curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
        curl_setopt($curl, CURLOPT_URL, $url);

        curl_setopt($curl, CURLOPT_USERAGENT, 'SeanPeterson');
        $content = curl_exec($curl);

        if(curl_errno($curl)){
            $this->respond('error:' . curl_error($curl));
         }

        curl_close($curl);

此代码的结果是损坏的 zip 文件，在尝试解压缩时变成 cpgz 文件。这是使用文本编辑器打开 zip 文件时存在的 header 信息

当用浏览器点击 link 时，它会完美下载文件。所以形成这个，我假设我一定是在使用 curl 时犯了一个错误。

非常感谢任何见解！

试试这个：

    $url = 'https://api.github.com/repos/SeanPeterson/Raspberry-Pi-Case/zipball/master';
    $curl = curl_init();
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($curl, CURLOPT_BINARYTRANSFER, 1);
    curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($curl, CURLOPT_URL, $url);

    curl_setopt($curl, CURLOPT_USERAGENT, 'SeanPeterson');
    $content = curl_exec($curl);


    $err = curl_error($curl);

    curl_close($curl);

    if ($err) {
        echo "cURL Error #:" . $err;
    }

    $fp = fopen("test.zip","wb");
    fwrite($fp,$content);
    fclose($fp);

认为您包括 header 可能会损坏 zip。
