我对Python还不熟悉。我正在使用Python3.x。我已经多次尝试更正此代码,但收到的错误消息很少。有人能帮我改正一下密码吗?你知道吗
import urllib.request as urllib2
#import urllib2
#import urllib2
import json
def printResults(data):
#Use the json module to load the string data into a directory
theJSON = json.loads(data)
#Now we can access the contents of json like any other python object
if "title" in theJSON["metadata"]:
print (theJSON["metadata"]["title"])
def main():
#Define the varible that hold the source of the Url
urlData= "http://earthquake.usgs.gov/earthquakes/feed/v1.0/summary/2.5_day.geojson"
#Open url and read the data
webUrl= urllib2.urlopen(urlData)
#webUrl= urllib.urlopen(urldata)
print (webUrl.getcode())
if (webUrl.getcode() == 200):
data= webUrl.read()
#Print our our customized result
printResults(data)
else:
print ("Received an error from the server, can't retrieve results " + str(webUrl.getcode()))
if __name__== "__main__":
main()
以下是我遇到的错误:
Traceback (most recent call last):

TypeError: the JSON object must be str, not 'bytes'
只需告诉python将它放入字符串中的bytes对象解码。 这可以通过使用
decode
函数来实现。你知道吗您可以通过添加if条件使函数更加健壮,例如:
