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”，这是一个会计软件解决方案，需要将日志条目从 laravel lumen 发送到“IMUIS”进行处理。但它在转换后给出了错误。

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

在英语中是指

"Error message": "Can not convert a System.String object to the System.Byte [] type."

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;
}

这也是响应:

    "result": {
        "CreateJournaalpostResult": false,
        "Journaalpost": "<?xml version=\"1.0\"?>\n<NewDataSet><BOE><JR>2018</JR><PN>5</PN><DAGB>20</DAGB><REK>20032</REK><TEGREK>40</TEGREK><FACT>0</FACT><BTW>4</BTW><BEDRBOEK>123.45</BEDRBOEK><DAT>08-05-2018</DAT><OPM>Anand testing from wsdl</OPM><BEDRBTW>21</BEDRBTW><OMSCHR>Testing from wsdl api</OMSCHR><BOEKSTUK>2018075</BOEKSTUK></BOE><DIGDOS><FILE>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</FILE></DIGDOS></NewDataSet>\n",

最佳答案

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() 解析它。

<?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;
    }
?>
