用 requests.post().text 来读取json代码老是报错 " json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0) " 而用 urlopen.read() 就可行 ，为什么？？？
先整体抓包一下：
urlopen.read()放回的是一个json代码（意外发现getheaders放回的是头信息）：
尝试打印出request.post的值发现它的结果是有道网页的html代码

- urlopen(url, data=None, proxies=None) : 创建一个表示远程url的类文件对象，然后像本地文件一样操作这个类文件对象来获取远程数据。
- 参数url表示远程数据的路径，一般是网址；
- 参数data表示以post方式提交到url的数据(玩过web的人应该知道提交数据的两种方式：post与get)；
- 参数proxies用于设置代理
- urlopen与requests.get()对比
- urlopen打开URL网址,url参数可以是一个字符串url或者是一个Request对象,返回的是http.client.HTTPResponse对象.http.client.HTTPResponse对象大概包括read()、readinto()、getheader()、getheaders()、fileno()、msg、version、status、reason、debuglevel和closed函数,其实一般而言使用read()函数后还需要decode()函数,返回的网页内容实际上是没有被解码或的,在read()得到内容后通过指定decode()函数参数,可以使用对应的解码方式。
- requests.get()方法请求了站点的网址,然后打印出了返回结果的类型,状态码,编码方式,Cookies等内容
