使用wordpressapi将数据作为图像上传到Wordpress

Question

我正在尝试获取图像的URL，下载它，然后使用wordpressapi将其上传到wordpress。这是我的密码：

def upload_media(self, media_url):
    # Get the last path component
    filename = media_url.split('/')[-1]
    response = requests.get(media_url)
    if response.status_code == 200:
        image = Image.open(BytesIO(response.content))
        upload_url = self.__upload_media_url()
        headers = { "Content-Disposition": f'attachment; filename={filename}'}
        files = { 'file': image.tobytes() }
        request = requests.post(upload_url, auth=(self.username, self.password), files=files, headers=headers)
        return request

每次失败时都会出现以下错误：

{'code': 'rest_upload_unknown_error', 'message': 'Sorry, this file type is not permitted for security reasons.', 'data': {'status': 500}}

最初我有以下代码，在我的本地机器上工作。但是，因为我想在Google云上运行这个函数，所以我没有访问文件系统的权限。因此，打开/关闭过程将不起作用。你知道吗

def upload_media(self, media_url):
    # Get the last path component
    filename = media_url.split('/')[-1]
    response = requests.get(media_url)
    if response.status_code == 200:
        with open(filename, 'wb') as file:
            file.write(response.content)
        upload_url = self.__upload_media_url()
        headers = { "Content-Disposition": f'attachment; filename={filename}'}
        files = { 'file': open(filename, 'rb')}
        request = requests.post(upload_url, auth=(self.username, self.password), files=files, headers=headers)
        os.remove(filename)
        return request

有办法吗？你知道吗

Answer 1

最终我不得不对我原来的功能做了两个修改。你知道吗

1. 添加Content-type: image/jpeg

2. 用data=代替file=

以下是不需要打开/关闭任何文件的工作功能：

def upload_media(self, media_url):
    # Get the last path component
    filename = media_url.split('/')[-1]
    response = requests.get(media_url)
    if response.status_code == 200:
        upload_url = self.__upload_media_url()
        headers = { "Content-Disposition": f"attachment; filename={filename}" , "Content-Type": "image/jpeg" } 
        return requests.post(upload_url, auth=(self.username, self.password), headers=headers, data=response.content)

Answer 2

根据https://pillow.readthedocs.io/en/stable/reference/Image.html#PIL.Image.Image.tobytesimage.tobytes()生成原始图像数据，而不是PNG或JPG压缩数据-因此，您尝试上载的不是允许的类型之一。你知道吗

把这句话放下：

image = Image.open(BytesIO(response.content))

然后使用：

files = { 'file':  BytesIO(response.content) }

我相信这会解决你的问题。你知道吗
