本文实例讲述了Python实现批量读取图片并存入mongodb数据库的方法。分享给大家供大家参考,具体如下:
我的图片放在E:\image\中,然后使用python将图片读取然后,显示一张,存入取一张(可以注释掉显示图片的语句),通过Gridfs的方式存入图片。代码如下:

print db.collection_names()
imgput = gridfs.GridFS(db)
dirs = 'G:\image'
files = os.listdir(dirs)
for file in files:
filesname = dirs + '\\' + file
print filesname
imgfile = iming.imread(filesname)
# iming.imsave('s.jpg',imgfile)
# print type(imgfile),imgfile
# imgfile.shape()
plt.imshow(imgfile)
plt.axis( 'off' )
plt.show()
f = file .split( '.' )
print f
datatmp = open (filesname, 'rb' )
data = StringIO(datatmp.read())
content = bson.binary.Binary(data.getvalue())
# print content
insertimg = imgput.put(data,content_type = f[ 1 ],filename = f[ 0 ])
datatmp.close()

希望本文所述对大家Python程序设计有所帮助。
