配置跨域

django需要调用github的api进行传照片，所以要配置跨域

这个是在settings文件里

INSTALLED_APPS = [
    'corsheaders',
]

MIDDLEWARE = [
    'django.middleware.common.CommonMiddleware',
    'corsheaders.middleware.CorsMiddleware',
]

views.py

def save_to_github(filename, content):
    url = f"{settings.GITHUB_API_URL}/repos/{settings.GITHUB_OWNER}/{settings.GITHUB_REPO}/contents/{filename}"
    headers = {
        'Authorization': f'token {settings.GITHUB_TOKEN}',
        'Content-Type': 'application/json'
    }
    data = {
        'message': f'Add {filename}',
        'content': content,
        'branch': settings.GITHUB_BRANCH
    }
    response = requests.put(url, headers=headers, json=data)
    if response.status_code == 201:
        return True
    return False
    
@method_decorator(csrf_exempt, name='dispatch')
class UploadImageAPIView(APIView):
    def post(self, request):
        if request.FILES:
            image_file = request.FILES.get('image')
            file_format = image_file.name.split('.')[-1]
            filename = 'ouchelper/' + f'{uuid1().hex}.{file_format}'
            content = base64.b64encode(image_file.file.read()).decode('utf-8')
            if save_to_github(filename, content):
                # image_url = f"https://raw.githubusercontent.com/{settings.GITHUB_OWNER}/{settings.GITHUB_REPO}/{settings.GITHUB_BRANCH}/{filename}"
                image_url = f"https://picture.daoxuan.cc/{filename}"
                data = {
                    'success': True,
                    'url': image_url,
                }
                return Response(data)
            else:
                data = {
                    'success': False,
                    'message': 'Failed to upload image'
                }
                return Response(data)
        else:
            data = {
                'success': False,
                'message': 'Unsupported file format'
            }
            return Response(data)

函数大概就是这个样子GITHUB_API_URL、GITHUB_OWNER、GITHUB_REPO都放在settings里面
GITHUB_TOKEN是token，怎么申请可以在网上搜索教程，正常的url应该是image_url = f”https://raw.githubusercontent.com/{settings.GITHUB_OWNER}/{settings.GITHUB_REPO}/{settings.GITHUB_BRANCH}/{filename}"这样的,只不过我使用cloudfare的worker代理了一下，所以绑定自己的域名进行访问了。
