测试具有post请求的django视图

我试图测试我的django视图，其中包含post请求

def save_movie(request):
'''
Fetch data and save to Movie model 
data obtained from post request is a string so need to clean it and convert to json
'''
if request.method == 'POST':
    movie_data = str(request.POST['movie_data'])
    movie_data = movie_data.replace("\'","\"")
    b=""
    for i in range(len(movie_data)):
        if movie_data[i] is "\"" and movie_data[i-1].isalpha() and movie_data[i+1].isalpha():
            b+="\'"
        else:
            b+=movie_data[i]
    json_data = json.loads(b)
    new_movie, created = Movie.objects.get_or_create(title=json_data['title'], episode_id=int(json_data['episode_id']), opening_crawl=json_data['opening_crawl'], director=json_data['director'], producer=json_data['producer'], release_date=json_data['release_date'], characters=str(json_data['characters']), planets=str(json_data['planets']), starships=str(json_data['starships']), vehicles=str(json_data['vehicles']), species=str(json_data['species']), created=parse_datetime(json_data['created']), edited=parse_datetime(json_data['edited']), url=json_data['url'])
    if created:
        new_movie.save()
        return HttpResponse('<h1>Movie Saved</h1>')
    else:
        return HttpResponse('<h1>Movie already Saved</h1>')

当我运行这个测试用例时，我得到了多值错误

    response = self.client.post(self.save_movie_url, {'title':'test', 'episode_id':1, 'opening_crawl':'test for movie', 'director':'director', 'producer':'producer', 'release_date':'test_date', 'characters':'test_chars', 'planets':'test_planets', 'starships':'test_starships', 'vehicles':'str_vehicles', 'species':'str_species', 'created':'2014-12-09T13:50:49.641000Z', 'edited':'2015-12-09T13:50:49.641000Z', 'url':'https://test.com'})

    raise MultiValueDictKeyError(key)

它似乎找不到应该出现在我的post请求中的movie_数据，因为视图从那里提取了它

如何解决此问题？

您能否共享完整的测试，包括作为post数据发送的整个字典？1）您的视图似乎正在处理JSON，但正在接受正常的post数据并进行大量预处理？2） 您没有在POST数据中传递名为“movie_data”的键？编辑了问题并添加了完整的字典。您的视图需要POST值“movie_data”，从外观上看应该是JSON字符串？你的帖子应该是self.client.post（self.save\u movie\u url，json.dumps（{…}））
