如何将Pdf文件转换为php中的字节数组并发送？

Question

我在 java、dotnet 和 python 中找到了 pdf 到字节数组，反之亦然。但我想在 php laravel 中将 pdf 转换为字节数组。我正在使用“IMUIS”，这是一种会计软件解决方案，需要将日记帐分录从 laravel lumen 发送到“IMUIS”进行处理。但转换后出现错误。

"Foutmelding": "Kan een object van het type System.String niet converteren naar het type System.Byte[]."

用英语表示

“错误信息”：“无法将 System.String 对象转换为 System.Byte [] 类型。”

文档在这里给出：

这是它的代码。

public function saveJournal($values = '') {
    //echo "adasd";dd();
    $partnerKey = $values->input('Partnerkey');
    $omgevingscode = $values->input('Environmentcode');  
    $file = file_get_contents($values->file('Pdffile'));
    $str = base64_encode($file);
    $options = array(
        \WsdlToPhp\PackageBase\AbstractSoapClientBase::WSDL_URL => env('IMUIS_URL'),
        \WsdlToPhp\PackageBase\AbstractSoapClientBase::WSDL_CLASSMAP => ClassMap::get(),
    );
    $login = new \mysdk\ImuisSDK\ServiceType\Login($options);
    if ($login->Login(new \mysdk\ImuisSDK\StructType\Login($partnerKey, $omgevingscode)) !== false) {
        $sessionid = $login->getResult()->SessionId;
    }

    $array = [
        'BOE' => [
           'JR' => '2018',
           'PN' => '5',
           'DAGB' => 20,
           'REK' => 20032,
           'TEGREK' => '40',
           'FACT' => 0,
           'BTW' => 4,
           'BEDRBOEK' => 123.45,
           'DAT' => '08-05-2018',
           'OPM' => 'Anand testing from wsdl',
           'BEDRBTW' => 21,
           'FACT' => 0,
           'OMSCHR' => 'Testing from wsdl api',
           'BOEKSTUK' => 2018075
        ],
        'DIGDOS' => [
            'FILE' => $str
        ]
    ];

    $journaalpost = ArrayToXml::convert($array, 'NewDataSet');//convert array to xml string

    $create = new \mysdk\ImuisSDK\ServiceType\Create($options);
    if ($create->CreateJournaalpost(new \mysdk\ImuisSDK\StructType\CreateJournaalpost($partnerKey, $omgevingscode, $sessionid, $journaalpost)) !== false) {
        $jsonResponse = $create->getResult();
    } else {
        $jsonResponse = $create->getLastError();
    }
    return $jsonResponse;
}

这也是回应：

要将 PDF 转换为字节数组，您必须使用 file_get_contents() 读取文档，然后通过函数 unpack() 对其进行解析。

<?php
    public function saveJournal($values = '') {
        $partnerKey = $values->input('Partnerkey');
        $omgevingscode = $values->input('Environmentcode');  
        $file = file_get_contents($values->file('Pdffile'));
        $byte_array = unpack("C*",$file);
        $base64_encode = base64_encode(serialize($byte_array));
        $options = array(
            \WsdlToPhp\PackageBase\AbstractSoapClientBase::WSDL_URL => env('IMUIS_URL'),
            \WsdlToPhp\PackageBase\AbstractSoapClientBase::WSDL_CLASSMAP => ClassMap::get(),
        );
        $login = new \mysdk\ImuisSDK\ServiceType\Login($options);
        if ($login->Login(new \mysdk\ImuisSDK\StructType\Login($partnerKey, $omgevingscode)) !== false) {
            $sessionid = $login->getResult()->SessionId;
        }

        $array = [
            'BOE' => [
               'JR' => '2018',
               'PN' => '5',
               'DAGB' => 20,
               'REK' => 20032,
               'TEGREK' => '40',
               'FACT' => 0,
               'BTW' => 4,
               'BEDRBOEK' => 123.45,
               'DAT' => '08-05-2018',
               'OPM' => 'Anand testing from wsdl',
               'BEDRBTW' => 21,
               'FACT' => 0,
               'OMSCHR' => 'Testing from wsdl api',
               'BOEKSTUK' => 2018075
            ],
            'DIGDOS' => [
                'FILE' => $base64_encode 
            ]
        ];

        $journaalpost = ArrayToXml::convert($array, 'NewDataSet');//convert array to xml string

        $create = new \mysdk\ImuisSDK\ServiceType\Create($options);
        if ($create->CreateJournaalpost(new \mysdk\ImuisSDK\StructType\CreateJournaalpost($partnerKey, $omgevingscode, $sessionid, $journaalpost)) !== false) {
            $jsonResponse = $create->getResult();
        } else {
            $jsonResponse = $create->getLastError();
        }
        return $jsonResponse;
    }
?>

我认为问题在于WsdlToPhp 构造了客户端代码，当它需要是byte[] 时，它会将PDF 实体作为String 发送。

所以我认为问题可能出在此处未显示的代码中。

您能否看一下WsdlToPhp 生成的代码，看看您是否可以灵活地对$journaalpost 进行序列化，看看您是否可以在那里修复？

Answer 3

// Convert the Base64 string back to text.
var byteString = atob(data.reportBase64Bytes);

// Convert that text into a byte array.
var ab = new ArrayBuffer(byteString.length);
var ia = new Uint8Array(ab);
for (var i = 0; i < byteString.length; i++) {
    ia[i] = byteString.charCodeAt(i);
}

// Blob for saving.
var blob = new Blob([ia], { type: "application/pdf" });

// Tell the browser to save as report.pdf.
saveAs(blob, "report.pdf");

// Alternatively, you could redirect to the blob to open it in the browser.
//document.location.href = window.URL.createObjectURL(blob);

IMUIS 软件中存在一个“bug”，因此无法从 php.ini 链接 pdf 文件。它可能由 Dotnet 完成，因为它的母语和由它构建的整个系统。感谢我所有的 SO 朋友为帮助我找到问题所做的努力，我已在致电支持后确认了此信息。所以在未来没有人被卡住（毕竟可能是 2018 年底）:)
