我想检查是否定期在任何Android设备上启用蓝牙.有没有使用BroadcastReceiver可以捕获的意图,还是有其他方法可以做到这一点？
我正在使用python脚本使用该BaseHTTPServer模块来执行我的Web服务器.下面是我的服务器代码:
import string,cgi,time
from os import curdir, sep
from BaseHTTPServer import BaseHTTPRequestHandler, HTTPServer
#import pri
class MyHandler(BaseHTTPRequestHandler):
def do_GET(self):
try:
if self.path.endswith("/"):
f = open(curdir + sep + "index.html")
self.send_response(200)
self.send_header('Content-type', 'text/html')
self.end_headers()
self.wfile.write("<HTML> GET OK.<BR>")
f.close()
return
return
except IOError:
self.send_error(404,'File Not Found: %s' % self.path)
def do_POST(self):
global rootnode
try:
ctype, pdict = cgi.parse_header(self.headers.getheader('content-type'))
if ctype == 'multipart/form-data':
query=cgi.parse_multipart(self.rfile, pdict)
self.send_response(200)
self.send_header('Content-type', 'text/html')
self.end_headers()
file = query.get('file')
self.wfile.write("<HTML> POST OK.<BR>")
f = open("data.zip", "wb")
f.write(file[0])
f.close() …我有以下代码,它检查数据库中的行数.
private void checkMMSRows(){
Cursor curPdu = getContentResolver().query(Uri.parse("content://mms/part"), null, null, null, null);
if (curPdu.moveToNext()){
int number = curPdu.getCount();
System.out.println(number);
}
}
我将每秒运行此代码并在值发生更改时执行某些操作.问题是,我如何"检测"变化？任何帮助,将不胜感激.
我正在尝试使用csv文件中的值更新数据库,以下是我的代码:
import MySQLdb as mdb
import sys
import csv
con = None
command = ''
new_name_list = []
old_name_list = []
duplicates = []
update_list = []
file = 'csv_file.csv'
listReader = csv.reader(open(file, 'r'))
for row in listReader:
new_name_list.append(row)
try:
con = mdb.connect('localhost', 'root', 'mypassword', 'mydb')
con.autocommit(True)
cur = con.cursor()
cur.execute("SELECT fil_name FROM file WHERE fil_name like 'boy%' and fil_job_id=1")
numrows = int(cur.rowcount)
for i in range(numrows):
file_name = cur.fetchone()
old_name_list.append(file_name[0])
d = dict(new_name_list)
for n in old_name_list:
try:
print …我想从未读的彩信获得附件,但我的代码不允许我这样做.我该怎么做呢？
代码从这里修改:
private void checkMMSMessages(){
// Create string arrays to store the queries later on
String[] columns = null;
String[] values = null;
// Calls the ContentResolver to query for columns with URI "content:mms"
Cursor curPdu = getContentResolver().query(Uri.parse("content://mms"), null, null, null, null);
if(curPdu.moveToNext()){
//String read = curRead.getString(curRead.getColumnIndex("read"));
// Gets ID of message
String id = curPdu.getString(curPdu.getColumnIndex("_id"));
// Gets thread ID of message
String thread_id = curPdu.getString(curPdu.getColumnIndex("thread_id"));
// Gets subject of message (if any)
String subject = …我有2个清单
old_name_list = [a-1234, a-1235, a-1236]
new_name_list = [(a-1235, a-5321), (a-1236, a-6321), (a-1234, a-4321), ... ]
我想以递归方式搜索old_name_list中的元素是否存在于new_name_list中,并返回与之关联的值,例如.old_name_list中的第一个元素返回a-4321,第二个元素返回a-5321,依此类推,直到old_name_list结束.
我尝试过以下内容并不起作用
for old_name, new_name in zip(old_name_list, new_name_list):
if old_name in new_name[0]:
print new_name[1]
方法我做错了还是我必须对它做一些小改动？先感谢您.
我正在尝试创建一个自定义 Woocommerce 支付网关，将客户重定向到支付网关页面以完成结账，我使用的代码process_payment如下：
public function process_payment( $order_id )
{
global $woocommerce;
// we need it to get any order details
$order = wc_get_order( $order_id );
//setting up needed variables for POST
$moovpay = new MoovPaySDK;
$paymentURL = //payment gateway API URL;
$time = date('YmdHis');
$secretKey = $this->private_key;
$merchant_code = $this->merchant_code;
$mid = $this->mid;
$orderID = zeroise($order_id, 8);
$backend_URL = //callback_URL;
$order_amount = $order->get_total();
$order_amount_CNY = wc_format_decimal( $order_amount * 5, 2 );;
$order_amount_CNY_no_dot = str_replace(".", "", $order_amount_CNY);
//initiate payment …
