Question

您知道如何验证iam用户名是否已存在？

我正在使用get_user尝试下面的代码，但是当用户不存在时，我收到了一个错误：The user with name teste cannot be found。

你知道这样做的方法吗？

c = boto.iam.connect_to_region("us-east-1")
while True:
    username = raw_input("Username:")
    password = raw_input("Password:")
    if not username or not password:
        print "Please enter a valid username and password"
    if c.get_user(username):
        print "Username already exist, please enter a different username..."

新尝试：

while True:
    username = raw_input("Username:")
    password = raw_input("Password:")
    if not username or not password:
        print "Please enter a valid username and password"
    try:
        if not c.get_user(username):
            print "Username valid"
    except BotoServerError, e:
        print "Username already exist

只需在调用周围进行try / except并处理异常。

from boto.exception import BotoServerError
c = boto.iam.connect_to_region("us-east-1")
while True:
    username = raw_input("Username:")
    password = raw_input("Password:")
    if not username or not password:
        print "Please enter a valid username and password"
    try:
        c.get_user(username)
    except BotoServerError, e:
        print(e.message)
