比特幣json rpc與python請求模塊？

我一直在努力幾個小時，而我只是不知道自己在做錯什麼。它只是用於規劃/研究（不是性能） - 用github中的一些代碼來玩 - 但我需要看到它的功能。比特幣json rpc與python請求模塊？

RPC_USER = username 
RPC_PASS = pasword 
rpc_id = ID HERE 
jsonrpc = "2.0" 
payload = {"jsonrpc": jsonrpc, "id": rpc_id, "method": method, "params": params} 
authstr = base64.encodestring(bytes('%s:%s' % (RPC_USER, RPC_PASS), 'utf-8')).strip() 
request_headers = {"Authorization": "Basic %s" % authstr, 'content-type': 'application/json'} 
try: 
    response = requests.get(RPC_URL, headers = request_headers, data = json.dumps(payload)).json() 
    print(response['result'])  
except Exception as e: print(str(e)) 
if response['id'] != rpc_id: 
     raise ValueError("invalid response id!")

我得到一個錯誤如下：

這裏是整個回溯：

Expecting value: line 1 column 1 (char 0)＃將異常

Traceback (most recent call last): 
    File "miner_2017.py", line 411, in <module> 
    solo_miner(bin2hex("------coinbase message here -----"), "-----bitcoin address here-----") 
    File "miner_2017.py", line 401, in solo_miner 
    mined_block, hps = block_mine(rpc_getblocktemplate(), coinbase_message, 0, address, timeout=60) 
    File "miner_2017.py", line 63, in rpc_getblocktemplate 
    try: return rpc("getblocktemplate", [{}]) 
    File "miner_2017.py", line 52, in rpc 
    if response['id'] != rpc_id: 
UnboundLocalError: local variable 'response' referenced before assignment

哪個後做一些看似乎是一個問題從字節對象而不是字符串對象解碼json對象。我不知道如何解決這個問題。由於json問題，似乎「響應」變量賦值失敗。如何從請求中獲取字符串形式的json對象？

有人能幫我嗎？由於

passphrase = getpass.getpass('Enter your wallet passphrase: ') 
timeout = raw_input('Unlock for how many seconds: ') 

answer = instruct_wallet('walletpassphrase', [passphrase, timeout]) 
if answer['error'] != None: 
    print answer['error'] 
else: 
    print answer['result']
