自学教程：Python3 实现将bytes图片转jpg格式

import urllib3import os#PIL图像处理标准库from PIL import Imagefrom io import BytesIOhttp = urllib3.PoolManager()response = http.request('GET','f.hiphotos.baidu.com/image/pic/item/8d5494eef01f3a29f863534d9725bc315d607c8e.jpg')result = response.data#将bytes结果转化为字节流bytes_stream = BytesIO(result)#读取到图片roiimg = Image.open(bytes_stream)# roiimg.show() #展示图片#print(type(result))#print(response.status)imgByteArr = BytesIO() #初始化一个空字节流roiimg.save(imgByteArr,format('PNG'))  #把我们得图片以‘PNG'保存到空字节流imgByteArr = imgByteArr.getvalue() #无视指针，获取全部内容，类型由io流变成bytes。# dir_name = os.mkdir('baiduimg')img_name = '1.jpg'with open(os.path.join('baiduimg',img_name),'wb') as f: f.write(imgByteArr)

def getImage(): datestr = getTimeStamp() imageUrl = "xxxxxurl" verifyText = requests.get(imageUrl,verify=False).content print(verifyText) return verifyText def getTimeStamp(): TimeStamp = str(time.time()) TimeStamp = TimeStamp.replace(".", "")[0:13] return int(TimeStamp) def startEbLoginSystem(username,password):  for i in range(1,100):  result = getImage()  img_name = str(i)+'.jpg'  path = "E:/yzmimages/" + img_name  with open(path, 'wb') as f:   f.write(result)

import urllib # 网络上图片的地址img_src = 'https://www.baidu.com/img/bd_logo1.png?where=super'# 将图片下载到本地urllib.urlretrieve(img_src,'D:/images/1.jpg')

import requestsfrom PIL import Imagefrom io import BytesIO response = requests.get(img_src)image = Image.open(BytesIO(response.content))image.save('D:/images/1.jpg')
