如何从HttpModule？访问会话变量？

我在.cs页面中设置了以下会话变量,我希望在以下位置访问HttpModule:

会话["用户名"] ="BLAH"

隐式类型变量如何var知道范围内未定义的类型(使用using)？

例:

还行吧

public class MyClass
{
    public void MyMethod        
    {
        var list = AStaticClass.GetList();
    }
}

但这不行

public class MyClass
{
    public void MyMethod        
    {
        List<string> list = AStaticClass.GetList();
    }
}

在最后一段代码中,我必须添加using System.Collections.Generic;它才能正常工作.

这是如何运作的？

我想用特殊字符编码URL.在我的情况下它是:( š, ä, õ, æ, ø它不是一个有限的列表).

urllib2.quote(symbol)给出了非常奇怪的结果,这是不正确的.这些符号怎么可以编码？

当目标函数抛出错误时，我试图退出多处理脚本，但父进程没有退出，而是挂起。

这是我用来复制问题的测试脚本：

#!/usr/bin/python3.5

import time, multiprocessing as mp

def myWait(wait, resultQueue):
    startedAt = time.strftime("%H:%M:%S", time.localtime())
    time.sleep(wait)
    endedAt = time.strftime("%H:%M:%S", time.localtime())
    name = mp.current_process().name
    resultQueue.put((name, wait, startedAt, endedAt))

# queue initialisation
resultQueue = mp.Queue()

# process creation arg: (process number, sleep time, queue)
proc =  [
    mp.Process(target=myWait, name = ' _One_', args=(2, resultQueue,)),
    mp.Process(target=myWait, name = ' _Two_', args=(2, resultQueue,))
    ]

# starting processes
for p in proc:
    p.start()

for p in proc:
    p.join()

# print results
results = {}
for …

好的，我正在尝试使用 py2app 为我的项目生成发行版。我仍然不确定我是否掌握了它的窍门。所以我的 setup.py 看起来像这样：

"""
This is a setup.py script generated by py2applet

Usage:
    python setup.py py2app
"""

from setuptools import setup
import setuptools

PACKAGES = ['sqlalchemy.dialects.sqlite']
MODULES = ['sqlite3']

APP = ['tvb/interfaces/web/run.py']
OPTIONS = {'argv_emulation': True,
           'packages': PACKAGES ,
           'includes' : MODULES }
DATA_FILES = []

setup(
    app=APP,
    data_files=DATA_FILES,
    packages = setuptools.find_packages(), 
    include_package_data=True,
    options={'py2app': OPTIONS},
    setup_requires=['py2app', "pyopengl", "cherrypy", "sqlalchemy", "simplejson", 
                          "formencode", "genshi", "quantities","numpy", "scipy",
                          "numexpr", "nibabel", "cfflib", "mdp", "apscheduler",
                          "scikits.learn"]
)

所以我的第一个问题是：我应该在 py2app 的模块中包含什么？py2app 是否知道扫描 setup_requires 中的内容并包含它们，或者我是否需要在 MODULES …

我真的试图围绕递归的工作原理并理解递归算法.例如,当我输入5时,下面的代码返回120,原谅我的无知,我只是没有看到原因？

def fact(n):
    if n == 0:
        return 1
    else:
        return n * fact(n-1)

answer = int (raw_input('Enter some number: '))

print fact(answer)

计划1:

#include<stdio.h>
#include<signal.h>
void handler(int sig);
void main()
{
    printf("PID: %d\n",getpid());
    signal(SIGABRT,handler);
    while(1){
        printf("Hai\n");
        sleep(1);
        abort();
    }
}

void handler(int sig)
{
    printf("Signal handled\n");
}

输出1:

$ ./a.out 
PID: 32235
Hai
Signal handled
Aborted (core dumped)
$

根据参考,中止功能的工作方式如下raise(SIGABRT).因此,abort()函数生成的信号是SIGABRT.为此,我创建了上述程序.

在该程序中,处理SIGABRT信号.在执行信号处理程序之后,它不会返回到调用它的主函数.处理程序完成后为什么不返回main函数？

计划2:

#include<stdio.h>
#include<signal.h>
void handler(int sig);
void main()
{
    printf("PID: %d\n",getpid());
    signal(SIGABRT,handler);
    while(1){
        printf("Hai\n");
        sleep(1);
    }
}

void handler(int sig)
{
    printf("Signal handled\n");
}

输出2:

$ ./a.out 
PID: 32247
Hai
Hai
Hai
Signal handled
Hai

我试图在Unity中的C#中读取剪贴板中的文本,然后将其设置为变量.

我看过这篇文章,但它似乎在Unity中不起作用:https: //msdn.microsoft.com/en-us/library/kz40084e(v = vs.110).aspx

我只想阅读纯文本.没有图像或任何东西.我还发现了一些其他文章,但Unity中的代码都不起作用.

当安装System.Collections.ImmutableNuGet下载程序集时System.Runtime,即使我已经使用.NET 4.6.1安装了该程序集.

此外,lib下的目录(如packages\System.Runtime.4.0.0\lib \net45)不包含dll文件,只包含空文件_._.

为什么会这样？为什么这有必要？我在这里错过了什么？

我从外部Web服务获取json字符串.我想events在数据库中保存数组中的事件.我该怎么List<FacebookEvents>办？

我目前的尝试不起作用: List< FacebookEvents > my_obj = JsonConvert.DeserializeObject < FacebookEvents > (jsonString);
