部署应用程序时,我似乎收到此错误,但在本地主机上提供服务时却没有:

E 2012-08-21 18:03:46.914 HTTP Error 400: Bad Request Traceback (most recent call last): File "/base/python27_runtime/python27_lib/versions/third_party/webapp2-2.3/webapp2.py

E 2012-08-21 18:03:46.916 Traceback (most recent call last): File "/base/python27_runtime/python27_lib/versions/1/google/appengine/runtime/wsgi.py", line 195, in Handle

生成此错误的代码位于此处(请原谅巨大的处理程序):

class Dashboard(MainHandler):

def check_if_live(self,b):
    url = ('http://api.justin.tv/api/stream/list.json?channel=%s' %b)
    contents = urllib2.urlopen(url)
    if contents.read() == '[]':
        return 'Offline'
    else:
        return 'Live'

def get(self, profile_id):
    u = User.by_name(profile_id.lower())
    if not u:
        self.redirect('/')
    elif self.user.name != profile_id:
        self.redirect('/profile/%s' %self.user.name)
    elif self.user and profile_id:
        current_user = self.user.name
        name1 = ''
        friend_name = ''
        team_imagee = ''
        key = ''

        for stream_title in streams:
            streams_title = stream_title.stream_title
        for stream in streams:
            streamss = stream.stream
        for months in month:
            monthss = months.month
        for countrys in country:
            countryss = countrys.country
        for days in day:
            dayss = days.day
        for years in year:
            yearss = years.year
        for clan in team_name:
                name1 = clan.team_name_anycase
        for clan in team_name:
                name2 = clan.team_name
        for image in team_images:
            team_imagee = image.key()
        for image2 in team_images2:
            team_imagee2 = image2.key()
        for img in imgs:
            key = img.key()
        for img2 in imgs2:
            key2 = img2.key()
        streamm = (streamss[(streamss.find('.tv/')+ 4):])
        check_if_life2 = self.check_if_live((streamss[(streamss.find('.tv/')+ 4):]))
        self.render('dashboard.html', streams = streams, stream_title2 = streamm, stream_title = streams_title, check_if_life = check_if_life2, team_name2 = name2,  imgs = imgs, team_img2 = team_imagee2, profile_image_posted = key2, posts = posts, profile_id = profile_id, country_var = countryss, day_var = dayss, year_var = yearss, month_var = monthss, current_user = current_user, friends = friends, team_img = team_imagee, team_name = name1, profile_image = key, username = self.user.name, email = self.user.email, firstname = self.user.first_name, last_name = self.user.last_name, country = self.user.country)
    else:
        self.redirect('/register')

这就是造成它的具体原因:

    streamm = (streamss[(streamss.find('.tv/')+ 4):])
    check_if_life2 = self.check_if_live((streamss[(streamss.find('.tv/')+ 4):]))

它利用了顶部的函数“check_if_live”。作为一个完全的python菜鸟,我一生都无法弄清楚为什么这个错误是实时生成的,而不是在本地主机上生成的。

编辑:

我仍然无法让 API 工作。有趣的是,如果您在地址栏中调用 API,例如http://api.justin.tv/api/stream/list.json?channel=nasltv,它可以正常工作。但是一旦它接触到应用程序引擎,它就会失败。我只需要索引这个 API!啊!

您调用的 API 中是否涉及身份验证?也许有一个重定向 cookie。IIRC prod 和 dev 之间的重定向行为不同。
