这是我的问题。我正在尝试从腐烂的西红柿API请求一个网址。现在问题是他们要求你让你的电影标题包含+标志,其中应该有空格。但是我不确定如何在app引擎端实现这一点,因为每当我尝试在app引擎上做同样的事情时,我都会得到同样的错误:
Traceback (most recent call last): File "/programming/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/lib/webapp2-2.5.2/webapp2.py", line 1535, in __call__ rv = self.handle_exception(request, response, e) File "/programming/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/lib/webapp2-2.5.2/webapp2.py", line 1529, in __call__ rv = self.router.dispatch(request, response) File "/programming/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/lib/webapp2-2.5.2/webapp2.py", line 1278, in default_dispatcher return route.handler_adapter(request, response) File "/programming/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/lib/webapp2-2.5.2/webapp2.py", line 1102, in __call__ return handler.dispatch() File "/programming/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/lib/webapp2-2.5.2/webapp2.py", line 572, in dispatch return self.handle_exception(e, self.app.debug) File "/programming/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/lib/webapp2-2.5.2/webapp2.py", line 570, in dispatch return method(*args, **kwargs) File "/Users/student/Desktop/Movie Rater/MovieRaterBackend/higgsmovies.py", line 12, in get page = urllib2.urlopen(site) File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py", line 126, in urlopen return _opener.open(url, data, timeout) File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py", line 400, in open response = meth(req, response) File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py", line 513, in http_response 'http', request, response, code, msg, hdrs) File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py", line 438, in error return self._call_chain(*args) File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py", line 372, in _call_chain result = func(*args) File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py", line 521, in http_error_default raise HTTPError(req.get_full_url(), code, msg, hdrs, fp) HTTPError: HTTP Error 400: Bad Request
这是我的代码:
title = self.request.get("title")
site = "http://api.rottentomatoes.com/api/public/v1.0/movies.json?apikey=" + constants.ROTTEN_TOMATOES_KEY + "&q=" + title + "&page_limit=1"
page = urllib2.urlopen(site)
soup = BeautifulSoup(page)
self.response.out.write(soup)
常量只是一个包含我所有密码和东西的python文件,而我正在用漂亮的汤来清理东西,但我确信这不是问题所在。只需访问url myapplication.com/about?title=your+title+goes+here即可访问此代码,其中myapplication将成为网站的网址,可能是某些appspot.com网址。
这适用于不包含+符号的网址。
非常感谢任何帮助!

这不会直接回答您的问题,但您是否尝试直接使用url fetch service:
例如:
from google.appengine.api import urlfetch
title = self.request.get("title")
site = "http://api.rottentomatoes.com/api/public/v1.0/movies.json?apikey=" + constants.ROTTEN_TOMATOES_KEY + "&q=" + title + "&page_limit=1"
result = urlfetch.fetch(site)

加号(“+”)是表单数据编码标准的一部分:application/x-www-form-urlencoded
查询字符串是问号(“?”)之后的所有内容,是表单数据 - 或者,在本例中是REST查询参数。所以他们的API在这里表现正常。

我还没有办法处理加号,因为appengine似乎推断这些是新的变量/值。但是,使用' +'以外的正则表达式只要访问URL的应用程序能够用[regex]而不是普通的' +'替换[space],这是整个问题的可行解决方案。看作该服务的预期应用是成为iPhone应用程序的后端,这种方法不应该有太多麻烦。我只需要确保我的正则表达式不包含在任何电影名称中,并且它不会太长。对于使用appengine将此类数据转发到另一个在线服务的Web应用程序,可以编写一个javascript脚本来正确处理。

我使用urllib.urlencode
。
示例:
params = { 'q' : 'value', 'apikey' : key_value }
request_url += urllib.urlencode(params)
urllib2.urlopen(request_url)
