我正在尝试向以下页面发出POST请求:http://search.cpsa.ca/PhysicianSearch

为了模拟单击"搜索"按钮而不填写任何表单,这会向页面添加数据.在查看chrome开发人员工具中的网络选项卡时,通过单击按钮获取POST标头信息.我发布这个而不是仅仅从其他类似问题复制解决方案的原因是我相信我可能没有得到正确的标题信息.格式是否正确,我是否抓住了正确的信息？我之前从未发过过POST请求.

这就是我设法拼凑的东西:

import urllib.parse
import urllib.request


data = urllib.parse.urlencode({'Host': 'search.cpsa.ca', 'Connection': 'keep-alive', 'Content-Length': 23796,
                                     'Origin': 'http://search.cpsa.ca', 'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8',
                                     'Cahce-Control': 'no-cache', 'X-Requested-With': 'XMLHttpRequest',
                                     'X-MicrosoftAjax': 'Delta=true', 'Accept': '*/*',
                                     'Referer': 'http://search.cpsa.ca/PhysicianSearch',
                                     'Accept-Encoding': 'gzip, deflate',
                                     'Accept-Language': 'en-GB,en-US;q=0.8,en;q=0.6',
                                     'Cookie': 'ASP.NET_SessionId=kcwsgio3dchqjmyjtwue402c; _ga=GA1.2.412607756.1459536682; _gat=1'})


url = "http://www.musi-cal.com/cgi-bin/query?%s"

data = data.encode('ascii')
with urllib.request.urlopen("http://search.cpsa.ca/PhysicianSearch", data) as f:
    print(f.read().decode('utf-8'))

此解决方案输出页面的HTML,但不包含我想要从POST请求中检索的任何数据.

AssertionError: Egg-link /home/daniel/other-rb/reviewboard does not match installed location of ReviewBoard (at /home/daniel/reviewboard)

我相信这是因为我使用相同的virtualenv在其他位置安装包.

我该如何解决这个问题？我猜我需要重定向Egg-link以匹配安装位置？

堆栈跟踪:

我正在尝试执行以下操作：

def test_fn(self):
    cool_dict = {}
    blah = Mock(spec=DictField, wraps=cool_dict)
    blah['key'] = 'val'
    print(cool_dict))
    return False

基本上，我想确保blaha 允许发生的任何事情DictField，但我希望发生的任何事情blah实际发生在cool_dict，因此我可以看到断言它具有某种状态。

我怎样才能做到这一点？上面的代码失败：

我正在尝试获取特定目录中每个文件的数据。现在我只是想获得最后修改日期。似乎我需要将此 WindowsPath 转换为字符串，但我找不到任何可以执行此操作的函数。

startDir = os.getcwd()

pt = r"\\folder1\folder2"

asm_pths = [pth for pth in Path(pt).iterdir()
            if pth.suffix == '.xml']


for file in asm_pths:
    (mode, ino, dev, nlink, uid, gid, size, atime, mtime, ctime) = os.stat(file)
    print("last modified: %s" % time.ctime(mtime))

我想在运行目标可执行文件后运行一些命令。

我知道我可以添加“启动前”任务；有没有“启动后”任务之类的东西？

这就是我要做的事情:去这里,然后点击"搜索".抓取数据,然后点击"下一步",然后继续按下,直到你没有页面.一切都达到了"下一步"的作用.这是我的代码.r.content的格式与我打印它的两次完全不同,表明GET和POST请求之间发生了不同的事情,即使我想要非常相似的行为.为什么会发生这种情况？

我觉得奇怪的是,即使在POST请求似乎返回错误的东西后,我仍然可以解析我需要的URL - 只是不是__EVENTVALIDATION输入字段.

错误消息(代码结束)表示内容不包含我需要发出后续请求的数据,但导航到页面显示它确实有这些数据,并且格式非常类似于第一页.

编辑:我正在打开基于HTML解析的网页,而且肯定是不对的.运行下面的代码将打开这些页面.

GET为我提供了一个包含以下数据的网站:

<input type="hidden" name="__VIEWSTATEGENERATOR" id="__VIEWSTATEGENERATOR" value="4424DBE6">
<input type="hidden" name="__VIEWSTATEENCRYPTED" id="__VIEWSTATEENCRYPTED" value="">
<input type="hidden" name="__EVENTVALIDATION" id="__EVENTVALIDATION" value="TlIgNH

虽然POST以明文形式在页面底部生成一个包含所有数据的站点,如下所示:

|0|hiddenField|__EVENTTARGET||0|hiddenField|__EVENTARGUMENT||0|hiddenField|_

坏r.content

我有一个方法从标准输入读取行并将行写入标准输出.

在JUnit测试中,如何将输入发送到方法,以及如何捕获其输出以便我可以对其进行断言？

我的requirements.txt已包含dataclasses在内，以向后移植python 3.6

然而，一些构建机器和同事使用 python 3.7，当尝试安装此模块时会失败。

有没有办法让数据类仅在必要时安装？

根据我的理解，当运行如下代码时：

for i in MyObject:
    print(i)

MyObject 的__iter__函数已运行，for 循环使用它返回的迭代器来运行循环。

是否可以在循环中访问此迭代器对象？它是一个隐藏的局部变量，还是类似的东西？

我想做以下事情：

for i in MyObject:
    blah = forloopiterator()
    modify_blah(blah)
    print(i)

我想这样做是因为我正在构建一个调试器，并且我需要在实例化迭代器后修改它（添加一个要在此循环期间、执行过程中迭代的对象）。我知道这是一种黑客行为，不应该以常规方式完成。直接修改 MyObject.items （迭代器正在迭代的内容）不起作用，因为迭代器仅计算一次。所以我需要直接修改迭代器。
