Question

我目前正在开发移动提取工具，这是用于联系人的android数据提取的代码，该代码一直运行到此行

if len(sys.argv) < 3:
sys.exit("Must give filenames as arguments")

但错误消息未显示，并且代码无法从sqlite提取数据。

下面是extract_contacts.py

的代码

import sqlite3
import sys
import codecs


class Contact:
def __init__(self, id):
    self.id = id
    self.phoneNumbers = []
    self.mailAddresses = []
    self.lastname = ""
    self.firstname = ""
    self.hasPhone = False

def GetPhones(self):
    return self.phoneNumbers

def AddPhone(self, number):
    self.phoneNumbers.append(number)

def AddMail(self, mail):
    self.mailAddresses.append(mail)

def GetMails(self):
    return self.mailAddresses

def SetFirstname(self, firstname):
    self.firstname = firstname

def SetLastname(self, lastname):
    self.lastname = lastname

def GetName(self):
    return (self.lastname, self.firstname)

def GetId(self):
    return self.id

def GetVCard(self):
    vcard = []
    vcard.append("BEGIN:VCARD")
    vcard.append("VERSION:2.1")
    vcard.append("N:" + self.lastname + ";" + self.firstname)
    if len(self.lastname) > 0 and len(self.firstname) > 0:
        vcard.append("FN:" + self.firstname + " " + self.lastname)
    elif len(self.lastname) > 0:
        vcard.append("FN:" + self.lastname)
    elif len(self.firstname) > 0:
        vcard.append("FN:" + self.firstname)
    for phone in self.phoneNumbers:
        vcard.append("TEL;type=CELL:" + phone)
    for mail in self.mailAddresses:
        vcard.append("EMAIL;type=INTERNET;type=HOME:" + mail)
    vcard.append("END:VCARD")
    return vcard

        if row is None: break
        if row[0] == 1: # Mail
            contacts[key].AddMail(row[2])
        elif row[0] == 6: # Name
            if row[4]:

                pass
            contacts[key].AddPhone(row[2])

fp = codecs.open(sys.argv[2], "w", "utf-8")

        if len(last) > 0 and len(first) > 0:
            string += last + " " + first

        mails = contacts[key].GetMails()
        for mail in mails:
            string += mail + " "
        print(string)
        fp.write("\n".join(contacts[key].GetVCard()))
        fp.write("\n")
fp.close()
c.close()
db.close()

无法从sqlite3提取android数据，但没有显示使用python的错误消息
