我有一个可以通过HTTP或HTTPS访问的URL.我想发送一个最快的HEAD或GET请求并获取响应代码,以便我知道URL是up还是down.
我如何使用Zend_HTTP_Client做到这一点？我使用了get_headers()函数,但在某些远程服务器上它非常慢.我不确定它是否处理HTTPS.
我有一个小片段,格式化时间戳的日期,如下所示: (YYYY-MM-DD H:M:S T ) Ex: 2011-09-29 17:00:46 EST or 2011-09-29 17:00:46 EDT
我想将EST和EDT转换为ET并显示ET,因此用户不必担心Dayligt的节省.我怎么做？
$timeZone = new DateTimeZone('America/New_York');
$processedDate = str_replace(".000000", "", $timestamp);
$dateTime = new DateTime($processedDate, new DateTimeZone('GMT'));
$dateTime->setTimezone($timeZone);
$processedDate = $dateTime->format('Y-m-d H:i:s') . ' ' . $dateTime->format('T');
echo processedDate;
谢谢
如何从使用Spring MVC实现的Controller将错误传递给视图文件？这些错误不是表单错误.只是将在"JSP"视图中的div内显示的业务逻辑错误.
这是我的控制器动作:
@RequestMapping(method = RequestMethod.POST)
public String processLoginForm(HttpServletRequest request, LoginForm loginForm,
BindingResult result, @SuppressWarnings("rawtypes") Map model)
{
loginForm = (LoginForm) model.get("loginForm");
String gotoURL = request.getParameter("gotoURL");
if (gotoURL == null || gotoURL == "")
{
String errorMessage = "No Redirect URL Specified";
return "loginerror";//loginerror is the view file I want to pass my error to.
}
model.put("loginForm", loginForm);
return "loginsuccess";
}
谢谢,
嗨,
在Zend Framwork 1中,我曾经有过一个application\configs\appsettings.xml用于存储params和值的函数,例如Rest API URL的主机名,调试设置以及dev,test和prod环境的其他应用程序特定设置.我可以在所有控制器和模型中使用此注册表,并在index.php中创建
$applicationEnvironment = 'development';
$config = new Zend_Config_Xml( APPLICATION_PATH . '/configs/appsettings.xml',
$applicationEnvironment, true );
Zend_Registry::set( 'config', $config );
我如何在Zend Framework 2中实现类似的功能？
谢谢
如何编写将用户输入限制在0-128范围内的3位数的正则表达式？
我一直在尝试,\d{1,3}但这允许匹配超过0-128范围.
谢谢
我正在尝试使用以下代码执行嵌套的AJAX调用.嵌套调用似乎不起作用.我做错了吗？
$.ajax({
type: 'GET',
url: "/public/customcontroller/dosomething",
cache: false,
dataType: "html",
success: function(html_input)
{
$.ajax({
type: 'GET',
url: "/public/customcontroller/getjobstatus",
cache: false,
dataType: "html",
success: function(html_input){
alert(html_input);
}
});
}
});
所有,
我有数组格式的以下数组.显示JSON格式只是为了方便用户使用.如何在php中使用键"name"对数组进行升序排序？
"food":
[
{
"id": 1,
"name": "dessert"
},
{
"id": 2,
"name": "maincourse"
},
{
"id": 3,
"name": "entrees"
},
{
"id": 4,
"name": "appetizers"
}
]
所需的结果是这样的数组:
"food":
[
{
"id": 4,
"name": "appetizers"
},
{
"id": 1,
"name": "dessert"
},
{
"id": 3,
"name": "entrees"
},
{
"id": 2,
"name": "maincourse"
}
]
所有,
我在键名中有一个带连字符的数组.如何在PHP中提取它的值？它返回0给我,如果我这样访问:
print $testarray->test-key;
这就是数组的样子
testarray[] = {["test-key"]=2,["hotlink"]=1}
谢谢
I am trying to write a regex for a case-insensitive hex number that should match either 8 or 12 or 32 in length.
The regex I have so far is:
/^[0-9A-F]{8}|[0-9A-F]{12}|[0-9A-F]{32}$/i
The pattern I am trying to test against is:
96AFC4ADA8C44A36B0CB1EC28531C3BC
or
870b72a9a020
or
569ac61e
But this doesn't seem to be matching the criteria.
Can you help?
Thanks,
我正在尝试从 URL 获取 JSON 文件并使用 Swift 返回内容。但是，代码let httpResponse = response as! NSHTTPURLResponse 在以下代码中的行失败。我在这一行遇到异常，Xcode 进入调试模式。
class func downloadJSONFile()->AnyObject
{
let requestURL: NSURL = NSURL(string: "http://www.learnswiftonline.com/Samples/subway.json")!
let urlRequest: NSMutableURLRequest = NSMutableURLRequest(URL: requestURL)
let session = NSURLSession.sharedSession()
var json:AnyObject = ""
let task = session.dataTaskWithRequest(urlRequest) {
(data, response, error) -> Void in
let httpResponse = response as! NSHTTPURLResponse
let statusCode = httpResponse.statusCode
if (statusCode == 200) {
do{
json = try NSJSONSerialization.JSONObjectWithData(data!, options:.AllowFragments)
}catch {
print("Error with Json: \(error)")
}
}
} …
