pdfkit與Django給出錯誤退出代碼1由於網絡錯誤：ContentOperationNotPermittedError

Question

我正在使用pdfkit將html文件轉換爲pdf。雖然我運行在python終端，它工作正常，並轉換相同的HTML文件。但是當我嘗試從django shell運行相同的代碼時，它會出現此錯誤。

下面給出代碼：

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)

這引發了我如下錯誤：

Answer 1

的Runn當在django裏面，它認爲你默認使用的是http://協議。這使得它在每個路徑的開始處添加一個http://。因此它假定參數是列表（因爲pdfkit也接受列表）。這可能是因爲this，但我不能肯定地說沒有關於服務器設置的更多細節。

你可以嘗試以下方法：

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) 

額外file://軍隊Django和pdfkit到你的文件系統中進行搜索。

Answer 2

得到了解決方案。顯然，pdfkit無法找到wkhtmltopdf可執行文件。我們必須明確提到wkhtmltopdf的路徑。

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

Answer 3

不知道爲什麼，但把輸入文件到列表似乎解決它：

pdfkit.from_file([html_url], pdf_url)
