标签： python django wkhtmltopdf pdfkit

我使用pdfkit将html文件转换为pdf。当我在python终端中运行时它工作正常并转换相同的html文件。但是当我尝试从django shell运行相同的代码时，会出现此错误。

以下是给出的代码：

html_url = "/Users/swarna/workspace/server/"+todays_date+"/ret_"+packages['wbn']+".html"
pdf_url = "/Users/swarna/workspace/server/"+todays_date+"/retpdf_"+packages['wbn']+".pdf"
pdfkit.from_file(html_url,pdf_url)

它抛出了下面给出的错误：

得到了解决方案。显然pdfkit无法找到wkhtmltopdf可执行文件。我们必须明确提到wkhtmltopdf的路径。

config = pdfkit.configuration(wkhtmltopdf='/usr/local/bin/wkhtmltopdf')
pdfkit.from_file(html_url,pdf_url, configuration=config)

在django中运行时，它认为您默认使用http://协议。这使得它在每个路径的开头添加http://。因此它假定参数是列表（因为pdfkit也接受列表）。这可能是因为this，但如果没有关于服务器设置的更多细节，我无法肯定地说。

您可以尝试以下方法：

html_url = "file:///Users/swarna/workspace/server/"+todays_date+"/ret_"+packages['wbn']+".html"
pdf_url = "file:///Users/swarna/workspace/server/"+todays_date+"/retpdf_"+packages['wbn']+".pdf"
pdfkit.from_file(html_url,pdf_url)

额外的file://强制django和pdfkit在你的文件系统中搜索。

不确定原因，但将输入文件放入列表似乎可以解决问题：

mysql> DELIMITER //

mysql> DROP PROCEDURE IF EXISTS `new_procedure`//
Query OK, 0 rows affected (0.00 sec)

mysql> CREATE DEFINER=`root`@`localhost` PROCEDURE `new_procedure`(

    ->   OUT `emplist3` VARCHAR(200),
    ->   OUT `emplist4` VARCHAR(200)
    -> )
    -> BEGIN
    ->   SELECT 'EMPLOYEE.NAME 1' INTO `emplist3`
    ->   FROM DUAL
    ->   WHERE `date_x` = `date_x`;
    -> 
    ->   SELECT 'EMPLOYEE.NAME 2' INTO `emplist4`
    ->   FROM DUAL
