问题描述
我有一个 PythonScript，当我运行它时，它会引发解码错误 none。我用谷歌搜索了解决方案，但无法弄清楚我的逻辑在哪里有缺陷。我理解它，因为 json 是空的并且不返回任何内容，但不知道为什么。如果相关，尝试为 cisco apic-em 做一个实验室。底部错误。
我的代码：
# Section 1. Setup the environment and variables required to interact with the APIC-EM
#===================================================
#+++++++++++Add Values+++++++++++++++
#import functions
import json
from requests import *
from my_apic_em_functions import *
from tabulate import *
# disable SSL certificate warnings
requests.packages.urllib3.disable_warnings()
#++++++++++++++++++++++++++++++++++++
#+++++++++++Add Values+++++++++++++++
# Path Trace API URL for flow_analysis endpoint
api_url = "https://sandBoxapicem.cisco.com/api/v1/flow-analysis" # URL of API endpoint
# Get service ticket number using imported function
ticket = get_ticket() # Call your function name that returns the service ticket
# Create headers for requests to the API
headers = {
"content-type": "application/json","X-Auth-Token": ticket
} # Create dictionary containing headers for the request with "content-type" and "X-Auth-Token"
#++++++++++++++++++++++++++++++++++++
#============================
# Section 2. display list of devices and IPs by calling get_host() and get_devices()
#============================
#+++++++++++Add Values+++++++++++++++
# display message identifying what is to be printed on the next line
print("currently displaying hosts: ")
# Call your function name that displays hosts
print_hosts()
# display message identifying what is to be printed
print("Currently displaying network devices: ")
# Call your function name that displays network devices
print_devices()
#++++++++++++++++++++++++++++++++++++
print("\n\n") # prints two blank lines to format output
# Section 3. Get the source and destination IP addresses for the Path Trace
# ============================
while True:
#+++++++++++Add Values+++++++++++++++
# Request user input for source IP address,e.g. "Please enter the source
# IP address"
s_ip = input("Enter source IP address: ") # Request user input for source host IP address,e.g. "Please enter the source host IP address"
d_ip = input("Enter destination IP address: ") # Request user input for destination host IP address,e.g. "Please enter the destination host IP address"
#++++++++++++++++++++++++++++++++++++
# VarIoUs error traps Could be completed here - POSSIBLE CHALLENGE
if s_ip != "" or d_ip != "":
# this creates a python dictionary that will be converted to a JSON
# object and posted
path_data = {
"sourceIP": s_ip,"destIP": d_ip
}
# Optional: Add statements that display the source and destination IP
# addresses that will be used. And asks user to verify. Loop if not
# verified by user.
break # Exit loop if values supplied
else:
print("\n\nYOU MUST ENTER IP ADDRESSES TO CONTINUE.\nUSE CTRL-C TO QUIT\n")
continue # Return to beginning of loop and repeat
# Section 4. Initiate the Path Trace and get the flowAnalysisId
#============================
#+++++++++++Add Values+++++++++++++++
# Post request to initiate Path Trace
# Convert the path_data dictionary into JSON for use in the request using json.dumps()
path = json.dumps(path_data)
# Make the request. Construct the post request to the API
resp = requests.post(api_url,path,headers=headers,verify=False)
# Inspect the return,get the Flow Analysis ID,put it into a variable
resp_json = resp.json()
flowAnalysisId = resp_json["response"][flowAnalysisId]
print("FLOW ANALYSIS ID: ",flowAnalysisId)
