发送python文件

我在尝试将照片上传到Facebook页面的脚本时遇到了一些问题。当只有字符串被传递时,我才能正常工作。页面帖子需要源文件(图像),这是我遇到问题的部分。这将返回400错误。

我不完全确定如何处理图像(目标是这样做是批量的,所以我理想地喜欢图像的zip文件。)

以下是正常工作的等效curl请求: curl -F'message = Book p://bit.ly/alaska'-F'ource=@alaska.jpg'-F' published = 0'-F'access_token = TEST'https://graph.facebook.com/act_id/photos

    post_params = [s for s in row.keys() if s not in targeting_params]
    post_params.append('targeting')

    for param in targeting_params:
        if len(row[param]) > 0:
            row[param] = row[param].split(",")

    targeting_dict = {k: row[k] for k in targeting_params}
    targeting_dict = dict([(k, v) for k, v in targeting_dict.items() \
                                   if len(v) > 0])

    row = {k: row[k] for k in post_params}
    row = dict([(k, v) for k, v in row.items() if len(v) > 0])

    message = row['message']
    row[u'message'] = u''.join(unichr(ord(c)) for c in row['message'])  

    imagename = row[u'source']
    imagedata = imagefile.extract(imagename)
    files = {'source': open(imagedata, 'rb')}
    api_method = 'https://graph.facebook.com/%s/feed?access_token=%s'
    response = requests.post(api_method % (pageid, token),params=row,files=files)

很抱歉,如果这还不够清楚的话。不确定什么是相关的,什么不是。我从我以前工作的脚本中改变的是在请求中添加了“文件”,所以我很确定这是我犯错的地方。

谢谢!

答案 0 :(得分:1)

试试这个:

files = { 'source': imagedata }

基本上你不能打开()imagedata这已经是一个字符串(open()仅适用于文件),所以你只需按原样提交它,而请求将负责多部分编码。

另请查看有关使用请求进行文件上传的this问题。
