以下由Laravel教學專欄為大家介紹如何使用Laravel-snappy匯出PDF，希望對需要的朋友有幫助！

前言

論壇裡有很多關於如何使用Laravel-snappy 的文章，但是很多都停留在安裝、基本範例，對於實際的應用既沒有說明用法，也沒有解答一些問題和疑惑，因此在此整理一下，權當做個記錄吧。

安裝

以ubuntu 為例

1.執行安裝wkhtmltopdf：

composer require h4cc/wkhtmltopdf-amd64 0.12.x
composer require h4cc/wkhtmltoimage-amd64 0.12.x

顧名思義，分別安裝的是wkhtmltopdf 和wkhtmltoimage。

2. 複製wkhtmltopdf 到ubuntu 執行指令的目錄中

sudo cp vendor/h4cc/wkhtmltoimage-amd64/bin/wkhtmltoimage-amd64 /usr/local/bin/
sudo cp vendor/h4cc/wkhtmltopdf-amd64/bin/wkhtmltopdf-amd64 /usr/local/bin/
//并使其可执行：
sudo chmod +x /usr/local/bin/wkhtmltoimage-amd64 
sudo chmod +x /usr/local/bin/wkhtmltopdf-amd64

3. 安裝laravel-snappy

composer require barryvdh/laravel-snappy

4. 將ServiceProvider 新增至config/app.php 中的providers 陣列中

Barryvdh\Snappy\ServiceProvider::class

5. 將Facades 加入到config/app.php 中的aliases 陣列中

&#39;PDF&#39; => Barryvdh\Snappy\Facades\SnappyPdf::class,
&#39;SnappyImage&#39; => Barryvdh\Snappy\Facades\SnappyImage::class,

6. 執行產生設定檔

php artisan vendor:publish --provider="Barryvdh\Snappy\ServiceProvider"

可以看到預設的設定檔為config/snappy.php：

return [
    &#39;pdf&#39; => [
        &#39;enabled&#39; => true,
        &#39;binary&#39;  => env(&#39;WKHTML_PDF_BINARY&#39;, &#39;/usr/local/bin/wkhtmltopdf&#39;),
        &#39;timeout&#39; => false,
        &#39;options&#39; => [],
        &#39;env&#39;     => [],
    ],
    &#39;image&#39; => [
        &#39;enabled&#39; => true,
        &#39;binary&#39;  => env(&#39;WKHTML_IMG_BINARY&#39;, &#39;/usr/local/bin/wkhtmltoimage&#39;),
        &#39;timeout&#39; => false,
        &#39;options&#39; => [],
        &#39;env&#39;     => [],
    ],
];

注意，這裡有個坑，預設binary 配置為/usr/local/bin/wkhtmltopdf 和/usr/local/bin/wkhtmltoimage，在第一個次使用的時候，會報錯/usr/local/bin/wkhtmltopdf不存在，這是因為在linux 系統下，wkhtmltopdf 和wkhtmltoimage 的真實路徑和名稱為：/usr/local/bin/wkhtmltopdf-amd64 和/usr/ local/bin/wkhtmltoimage-amd64。

因此，需要把設定資訊修改為：

&#39;pdf&#39; => [
        ...
        &#39;binary&#39;  => env(&#39;WKHTML_PDF_BINARY&#39;, &#39;/usr/local/bin/wkhtmltopdf-amd64&#39;),
        ...
    ],
    &#39;image&#39; => [
        ...
        &#39;binary&#39;  => env(&#39;WKHTML_IMG_BINARY&#39;, &#39;/usr/local/bin/wkhtmltoimage-amd64&#39;),
        ...
    ],

開始使用

//使用方法1
$pdf = \PDF::loadView(&#39;welcome&#39;, $data);
return $pdf->download(&#39;welcome.pdf&#39;);
//使用方法2
$html = &#39;<html><head><meta charset="utf-8"></head><h1 id="订单id">订单id</h1><h2 id="">12346546</h2></html>&#39;;
$pdf = \PDF::loadHTML($html);
return $pdf->inline();

很多部落格裡沒有提到，使用方法1中，會報這樣的錯誤：

The exit status code &#39;1&#39; says something went wrong: stderr: "Loading pages (1/6) [> ] 0% [======> ] 10% QSslSocket: cannot resolve CRYPTO_num_locks QSslSocket: cannot resolve CRYPTO_set_id_callback QSslSocket: cannot resolve CRYPTO_set_locking_callback QSslSocket: cannot resolve sk_free QSslSocket: cannot resolve sk_num QSslSocket: cannot resolve sk_pop_free QSslSocket: cannot resolve sk_value QSslSocket: cannot resolve SSL_library_init QSslSocket: cannot resolve SSL_load_error_strings QSslSocket: cannot resolve SSLv3_client_method QSslSocket: cannot resolve SSLv23_client_method QSslSocket: cannot resolve SSLv3_server_method QSslSocket: cannot resolve SSLv23_server_method QSslSocket: cannot resolve X509_STORE_CTX_get_chain QSslSocket: cannot resolve OPENSSL_add_all_algorithms_noconf QSslSocket: cannot resolve OPENSSL_add_all_algorithms_conf QSslSocket: cannot resolve SSLeay QSslSocket: cannot call unresolved function CRYPTO_num_locks QSslSocket: cannot call unresolved function CRYPTO_set_id_callback QSslSocket: cannot call unresolved function CRYPTO_set_locking_callback QSslSocket: cannot call unresolved function SSL_library_init QSslSocket: cannot call unresolved function SSLv23_client_method QSslSocket: cannot call unresolved function sk_num [==================> ] 31% QSslSocket: cannot call unresolved function SSLv23_client_method QSslSocket: cannot call unresolved function SSL_library_init [============================================================] 100% Counting pages (2/6) [============================================================] Object 1 of 1 Resolving links (4/6) [============================================================] Object 1 of 1 Loading headers and footers (5/6) Printing pages (6/6) [> ] Preparing [============================================================] Page 1 of 1 Done Exit with code 1 due to network error: UnknownNetworkError QSslSocket: cannot call unresolved function CRYPTO_num_locks QSslSocket: cannot call unresolved function CRYPTO_set_id_callback QSslSocket: cannot call unresolved function CRYPTO_set_locking_callback " stdout: "" command: /usr/local/bin/wkhtmltopdf-amd64 --lowquality &#39;/tmp/knp_snappy612c3edcdfc855.21787864.html&#39; &#39;/tmp/knp_snappy612c3edcdfce49.80482557.pdf&#39;.

執行：

sudo apt-get update
sudo apt install libssl1.0-dev

修復完成，匯出welcome 頁面。

如果使用 save () 方法儲存，預設儲存到 /public 資料夾下，如果檔案名稱相同的情況下，第二次儲存會提示檔案已經存在。
