Question

我试图找出为什么我无法传递我的两个变量以使API调用起作用。我知道当我在其位置放置静态名称/密钥时，API调用有效。任何帮助，将不胜感激。

import httplib

#Print my list to choose from. 
servers = {'server1.com':'#######','server2.com':'######'}
for server, key in servers.items():
    print server

#User chooses which node, it should print what they chose, then store into 
variable to send for API Post. 
node = raw_input("Which node would you like to check Network Bytes for? ")
if node == server:
    print serves.item(server)
    print servers.item(key)
    box = servers.item(server)
    api = servers.item(key)


headers = {'Content-Type': 'application/json', 'Accept': 'application/json', 
'Authorization': 'GetData apikey=' + api}
body = r"""{
  "cycle": "5min",
  "from": 0,
  "metric_category": "net",
  "metric_specs": [
    {
      "name": "bytes_in"
    }
  ],
  "object_ids": [
    0
  ],
  "object_type": "device",
  "until": 0
}
"""
conn = httplib.HTTPSConnection(box)
conn.request('POST', '/api/v1/metrics', headers=headers, body=body)
resp = conn.getresponse()
print resp.read()

Answer 1

您应该使用json模块将Python dict（标头）转换为json对象。虽然它们相似但语法略有不同。

我在这里看到的另一个问题是，当你测试它时，server是未定义的。您在server循环中创建了for，但在if node == server:之前它已超出范围。也许您可以用以下内容替换该部分：

#User chooses which node, it should print what they chose, then store into 
variable to send for API Post. 
box = raw_input("Which node would you like to check Network Bytes for? ")
api = servers.get(node, None):
print "box/node:", box
print "  api   :", api

你的循环逻辑不正确，因为它迭代字典但总是保留最后一个k，v对。

servers = {'server1.com':'#######','server2.com':'######'}
for server, key in servers.items():
    print server

这基本上意味着每次运行时，它将从dict中保持相同的值。你不应该在你的循环之外使用server / key变量，它不对，你可能会发现奇怪的行为

但问题在于您的字典检索

if node == server:
    **print serves.item(server)** # there's a typo here
    print servers.item(key)
    box = servers.item(server)
    api = servers.item(key)

如果您想从字典中获取密钥的值，请使用servers.get(server)或servers[server]。

我不确定你为什么要查看if node == server？您可以消除它，只需直接从服务器dict：box = servers.get(node)
