在冻结的应用程序中使用请求时出错答案

【问题标题】：Error using Requests in a frozen app在冻结的应用程序中使用请求时出错
【发布时间】：2014-02-24 23:08:23
【问题描述】：

我正在尝试在冻结的应用程序中使用出色的请求库。该代码在解释时工作正常，但当我生成 dist 可执行文件时它停止工作。

我尝试了这个解决方案，但它不起作用 (Requests library: missing file after cx_freeze)

我的 setup.py 文件：

import esky.bdist_esky
from esky.bdist_esky import Executable as Executable_Esky
from cx_Freeze import setup, Executable
from myapp import VERSION
import requests.certs

packages = [
    'PIL',
    '_winreg',
    'esky',
    ]

includes = [
    'PySide',
    'sys',
    'os',
    'datetime',
    'threading',
    'Queue',
    'uuid',
    'requests',
]

excludes = [
    'TKinter',
    'tcl',
    'ttk',
]

include_files =["icon-16px.ico",
                "icon-32px.ico",
                "logo-t-160x56.png",
                ]

setup(
    scripts = [
        Executable_Esky(
            "myapp.py",
            gui_only = False,
            icon = "icon-16px.ico",
        ),
    ],
    data_files = include_files,
    options={"build_exe":
                 {"packages":packages,
                  "includes": includes,
                  "include_files": include_files + [(requests.certs.where(),'cacert.pem')],
                  "excludes": excludes,
                  "optimize": 2,
                  "icon":"icon-16px.ico",
                 },
             "bdist_esky":{
                 'freezer_module':"cxfreeze",
                 'includes': includes,
                 'excludes': excludes,
             },
    },
    executables = [Executable(script="myapp.py",base="Win32GUI")],
)

追溯：

【问题讨论】：

github.com/kennethreitz/requests/issues/… 看起来适用。
是的，该线程有（可能的）答案。 requests 正在查找 SSL 证书文件，但在冻结时，您需要包含该文件的副本并告诉 requests 它在哪里。
我尝试导入证书文件，但没有成功，我会继续努力，谢谢大家的提示。

【解决方案1】：

或者你可以使用

import requests.certs
build_exe_options = {"include_files":[(requests.certs.where(),'cacert.pem')]}

【解决方案2】：

我在 github(https://github.com/kennethreitz/requests/issues/557#issuecomment-6420819) 上的这个问题之后得到了这个。感谢 Martjin Pieters 的提示。

首先，我将 cacert.pem 文件放在我的项目文件夹中，然后将其包含在冻结的应用程序中：

include_files =["icon-16px.ico",
                "icon-32px.ico",
                "logo-t-160x56.png",
                "cacert.pem",
                ]

setup(
    scripts = [
        Executable_Esky(
            "myapp.py",
            gui_only = False,
            icon = "icon-16px.ico",
        ),
    ],
    data_files = include_files,
    options={"build_exe":
                 {"packages":packages,
                  "includes": includes,
                  "include_files": include_files,
                  "excludes": excludes,
                  "optimize": 2,
                  "icon":"icon-16px.ico",
                 },
             "bdist_esky":{
                 'freezer_module':"cxfreeze",
                 'includes': includes,
                 'excludes': excludes,
             },
    },
    executables = [Executable(script="myapp.py",base="Win32GUI")],
)

最后，您必须在每个 POST 或 GET 中使用 requests 指明此证书，如下所示：

r = requests.post(url, data=data, verify = os.path.join(appdata,'cacert.pem'))
