DjanGo裏做下載文件

相對於php做頁面，django我很不熟悉。所以詢問了熟悉的朋友同事，記錄如下。

當然php做下載文件很簡單：

header("Content-type: test/html");
header("Content-Disposition: attachment; filename=test.txt");
echo "aa/n";
echo "bb/n";
echo "cc/n";
exit;

 

在django裏，定義了url之後，只要在view裏添加如下代碼匹配就可以了

def download_file(request): 
    from django.http import HttpResponse	    
    ## CSV
    #import csv    
    #response = HttpResponse(mimetype='text/csv')
    #response['Content-Disposition'] = 'attachment; filename=my.csv'
    #writer = csv.writer(response)
    #writer.writerow(['First row', 'Foo', 'Bar', 'Baz'])
    #writer.writerow(['Second row', 'A', 'B', 'C', '"Testing"', "Here's a quote"])

    # Text file
    #response = HttpResponse(mimetype='text/plain')                                 
    #response['Content-Disposition'] = 'attachment; filename=my.txt'              
    #response.write("aa/n")
    #response.write("bb") 
    
    # PDF file 
    #http://code.djangoproject.com/svn/django/branches/0.95-bugfixes/docs/outputting_pdf.txt
    from reportlab.pdfgen import canvas   
    response = HttpResponse(mimetype='application/pdf')
    response['Content-Disposition'] = 'attachment; filename=somefilename.pdf'
    p = canvas.Canvas(response)
    p.drawString(100, 100, "Hello world.")
    p.showPage()
    p.save()

          
    return response
