Requests works and URLFetch doesn't

I'm trying to make a request to the particle servers in python in a google app engine app. In my terminal, I can complete the request simply and successfully with requests as: res = requests.get('https://api.particle.io/v1/devices', params={"access_token": {ACCESS_TOKEN}}) But in my app, the same thing doesn't work with urlfetch, which keeps telling me it can't find the access tok

请求有效并且URLFetch不能

我试图在谷歌应用程序引擎应用程序中向Python中的粒子服务器发出请求。 在我的终端中,我可以简单而成功地完成请求,如下所示: res = requests.get('https://api.particle.io/v1/devices', params={"access_token": {ACCESS_TOKEN}}) 但在我的应用程序中,同样的事情不适用于urlfetch,它一直告诉我它找不到访问令牌: url = 'https://api.particle.io/v1/devices' payload = {"access_token": {ACCESS_TOKEN}}

python upload string with https post

This question already has an answer here: How are parameters sent in an HTTP POST request? 7 answers When using the files parameter, requests creates the headers and body required to post files. If you don't want your request formated like that you can use the data parameter. url = 'http://httpbin.org/anything' headers = {'content-type': 'application/octet-stream'} files = {'file': 'I

用https post发送python上传字符串

这个问题在这里已经有了答案: 如何在HTTP POST请求中发送参数? 7个答案 使用files参数时, requests会创建发布文件所需的标题和正文。 如果你不希望你的请求像这样形成,你可以使用data参数。 url = 'http://httpbin.org/anything' headers = {'content-type': 'application/octet-stream'} files = {'file': 'ID,Namen1,test'} r = requests.post(url, data=files, headers=headers, auth=('user', 'password')) print

Using PIL to analyze a video frame by frame

I'm working on using PIL to average the pixel intensities over a subarea of a video. What I want to do is: -Use ffmpeg to turn the video into several frames -Use PIL to choose a window in each frame (this is the step I'd like help with) -Do some sort of analysis on that window in each frame, and aggregate the data (like, say, average color vs. time) I'm at quite a loss as to

使用PIL逐帧分析视频

我正在使用PIL来平均视频分区中的像素强度。 我想要做的是: - 使用ffmpeg将视频转成几个帧 - 使用PIL在每一帧中选择一个窗口(这是我想要帮助的一步) - 在每一帧中对该窗口进行某种分析,然后汇总数据(比如平均颜色与时间) 我对于如何做中间步骤感到不知所措 - 有没有人有建议? 使用Tkinter找到解决方案: import Tkinter import Image, ImageDraw, ImageTk window = Tkinter.Tk() window.title('Calcium Im

Good library for encoding videos in a dynamic language?

I'm looking for an effective library for encoding videos. I would prefer something in one of the Ruby/Python ilk type languages, but I'd use libraries in C or PHP that were good. Essentially, I'm looking for something that wraps ffmpeg, and would allow me to convert H.264 .mp4's into .theora.ogv, .webm, and (this would be nice) .flv files. Worst case, I could always just use a

用动态语言编码视频的好库?

我正在寻找一个有效的视频编码库。 我更喜欢Ruby / Python流行类型语言之一,但我会使用C或PHP中的库,这很好。 从本质上讲,我正在寻找包装ffmpeg的东西,并允许我将H.264 .mp4转换为.theora.ogv,.webm和(这将是很好的).flv文件。 最糟糕的情况是,我总是可以使用任何语言来本地执行ffmpeg,使用类似命令(“ffmpeg -i ... etc”)的东西,但如果可能的话,我更喜欢某种更高级别/更高级别的语言。 我已经看过RVideo,但

What's a good Python library to manipulate frames of a video file?

I'm looking for a Python video processing library, similar to PIL, where I can iterate through all the frames of a source video, access the pixel data for each frame, draw onto each frame and save the result as a new video file. I've found a couple of similar questions, but they are pretty old now: Best video manipulation library for Python? python video library They recommend PyM

什么是一个好的Python库来操纵视频文件的帧?

我正在寻找一个Python视频处理库,类似于PIL,我可以遍历源视频的所有帧,访问每帧的像素数据,绘制到每个帧并将结果保存为新的视频文件。 我发现了几个类似的问题,但现在它们已经很老了: 最佳的Python视频操作库? 蟒蛇视频库 他们推荐PyMedia和PyFFMPEG。 PyMedia似乎过时了(但可能仍然有效?)和PyFFMPEG,而最近几乎没有文档。 在我按下之前,我没有在Ubuntu 10.10上安装这些操作系统,请问: a)我应该看一

Programmatically generate video or animated GIF in Python?

I have a series of images that I want to create a video from. Ideally I could specify a frame duration for each frame but a fixed frame rate would be fine too. I'm doing this in wxPython, so I can render to a wxDC or I can save the images to files, like PNG. Is there a Python library that will allow me to create either a video (AVI, MPG, etc) or an animated GIF from these frames? Edit: I

以编程方式在Python中生成视频或动画GIF?

我有一系列想要从中创建视频的图像。 理想情况下,我可以为每个帧指定帧持续时间,但固定帧速率也可以。 我在wxPython中这样做,所以我可以渲染到wxDC,或者我可以将图像保存为文件,如PNG。 有没有一个Python库允许我从这些框架创建视频(AVI,MPG等)或动画GIF? 编辑:我已经试过PIL,它似乎并没有工作。 有人可以用这个结论纠正我,还是建议另一个工具包? 这个链接似乎支持我关于PIL的结论:http://www.somethinkodd

Why are classes listed in the list of built

The Python docs lists property() as a built-in function. However, the function description has the keyword "class" in front of it in the docs. class property (fget=None, fset=None, fdel=None, doc=None) This also happens with class set ([iterable]) and class slice (stop) What does this mean? - why are classes listed under built-in functions. Is this just a documentation i

为什么在列表中列出类

Python文档将property()列为内置函数。 但是,函数描述在文档中的前面有关键字“class”。 类属性 (fget = None,fset = None,fdel = None,doc = None) 这也发生在 类集 ([iterable]) 和 类切片 (停止) 这是什么意思? - 为什么在内置函数下列出类。 这仅仅是一个文档问题,还是有技术上的原因? 编辑:我不是问property()如何工作。 Python术语表定义了一个函数: 一系列向调用者返回一些值的

What does REST's principle of statelessness actually means?

After reading the introductory articles on REST (Fielding's thesis and other) my perception of statelessness is that there should be no session objects on the server side. Yet, i see Flask (and maybe other REST frameworks in different technologies that i do not know about) gives us a session object to store information on the server in this example: @app.route('/login', methods=['GET', 'POS

REST的无国籍原则实际上意味着什么?

在阅读关于REST(Fielding的论文和其他)的介绍性文章之后,我对无状态的理解是服务器端不应该有会话对象。 然而,在这个例子中,我看到了Flask(也许还有其他我不知道的技术中的REST框架)为我们提供了一个会话对象来存储服务器上的信息: @app.route('/login', methods=['GET', 'POST']) def login(): if request.method == 'POST': session['username'] = request.form['username'] return redirect(url_for('inde
