在这段代码中,如果没有输出图片,可能是因为标题中含有特殊字符导致无法正确保存图片。为了查找标题中是否含有特殊字符,可以在`file_path()`方法中添加一些调试信息来检查。
以下是修改后的代码,用于查找标题中是否含有特殊字符:
```python
class PicSpiderPipeline(ImagesPipeline):
def get_media_requests(self, item, info):
image_requests = super().get_media_requests(item, info)
for img_req in image_requests:
img_req.item = item
return image_requests
def file_path(self, request, response=None, info=None, *, item=None):
old_path = super().file_path(request, response, info)
title = request.item['title']
# 打印标题用于调试
print('Title:', title)
save_path = os.path.join(settings.IMAGES_STORE, title)
image_name = old_path.replace('full/', '')
return os.path.join(save_path, image_name)
```
通过添加打印语句`print('Title:', title)`,可以在运行代码时查看标题的具体内容。这样可以帮助你确定是否存在特殊字符或其他问题导致无法正确保存图片。请确保在运行代码之前已经设置了适当的日志级别,以便能够看到打印的调试信息。
