使用app引擎中的报告实验室生成pdf的问题

Question

我正在尝试使用带有python的reportlab生成pdf。现在，每当我调用函数从get（self）函数生成pdf时它都可以正常工作，但是当从post（self）调用函数时，同样的事情不起作用。在日志中测试，生成pdf的功能在两种情况下都运行良好。问题似乎在pdf输出中（get和post）。我试过保持内容处置作为附件和内联但无济于事。

以下是generatePdf：

的代码部分

class PDFHandler(BlogHandler):


def get(self):

    self.render("create_offer_letter.html")
    candidate_name = "Siddhant"
    candidate_email ="ssjjs@ksks.com"
    candidate_phone = "939393993"
    address_part   = ['sjsjjs','ksksksks']
    confirmation_date = "22/07/2013"
    coursefee = "282828"
    admissionfee = "8388383"
    institute ="NIMT"
    course ="MBA"
    feeterm ="Trimester"
    #generatePdf(self,candidate_name,candidate_email,candidate_phone,address_part,confirmation_date,coursefee,admissionfee,institute,course, feeterm)
def post(self):   

    self.render("create_offer_letter.html")
    candidate_name = "Siddhant"
    candidate_email ="ssjjs@ksks.com"
    candidate_phone = "939393993"
    address_part   = ['sjsjjs','ksksksks']
    confirmation_date = "22/07/2013"
    coursefee = "282828"
    admissionfee = "8388383"
    institute ="NIMT"
    course ="MBA"
    feeterm ="Trimester"
    generatePdf(self,candidate_name,candidate_email,candidate_phone,address_part,confirmation_date,coursefee,admissionfee,institute,course, feeterm)

我想它必须用http标题做些什么？我不确定。
