scrapy Pipeline TypeError:只能将str（而不是“dict”）连接到str

我有一个刮擦蜘蛛，我想连接管道我的刮擦项目是

def parse(self, response):
    x = response.xpath("//script[starts-with(.,'window._sharedData')]/text()").extract_first()
    json_string = x.strip().split('= ')[1][:-1]
    data = json.loads(json_string)
    edges = data['entry_data']['ProfilePage'][0]['graphql']['user']['edge_owner_to_timeline_media']['edges']
    for i in edges:
        url = 'https://www.instagram.com/p/' + i['node']['shortcode']
        video = i['node']['is_video']
        date_posted_timestamp = i['node']['taken_at_timestamp']
        date_posted_human = datetime.fromtimestamp(date_posted_timestamp).strftime("%d/%m/%Y %H:%M:%S")
        like_count = i['node']['edge_media_preview_like']['count'] if "edge_media_preview_like" in i['node'].keys() else ''
        comment_count = i['node']['edge_media_to_comment']['count'] if 'owner' in i['node'].keys() else ''
        handle = i['node']['owner']['id'] if 'owner' in i['node'].keys() else ''
        usernameid = i['node']['owner']['username']
        captions = ""
        if i['node']['edge_media_to_caption']:
            for i2 in i['node']['edge_media_to_caption']['edges']:
                captions += i2['node']['text'] + "\n"
        if video:
            image_url = i['node']['display_url']
        else:
            image_url = i['node']['thumbnail_resources'][-1]['src']
        item = {'handleid': handle,'usernameid': usernameid,'postURL': url, 'isVideo': video, 'date_posted': date_posted_human,
                'timestamp': date_posted_timestamp, 'likeCount': like_count, 'commentCount': comment_count, 'image_url': image_url,
                'captions': captions[:-1]}
        if video:
            yield scrapy.Request(get_url(url), callback=self.get_video, meta={'item': item})
        else:
            item['videoURL'] = ''
            yield item

pipelines.py的内容：

class InstascraperPipeline:
def process_item(self, item, spider):
    print("pipeline :" + item, ['handleid'][0])
    return item

它给了我这个错误，我不知道从这以后该怎么办

谁能帮我一下我做错了什么吗？

在这行：

print("pipeline :" + item, ['handleid'][0])

首先是一个字符串（

“管道：”

），然后是一个dict 需要将dict转换为字符串，以便附加它

print("pipeline :" + str(item['handleid'][0]))

令人惊讶的感谢您的帮助：）这解决了我的问题：D欣赏一个小问题管道正在打印所需文本的第一个字母或第一个数字为什么？管道：o应该说管道：omnesinfluencers有什么想法吗？@abbasNoufal idk，这是在你上面提供的代码中，只需删除[0]惊人的：D你刚刚让我的一天我还在学习，你让我学到了一个新东西：）非常感谢：）
