當使用F.write（）時，爲什麼我會得到「TypeError：並非在字符串格式化期間轉換的所有參數？」？

Question

我從API接收到一個JSON文件。我將以自定義格式將其寫入文件。我的腳本是：

import logging,json,urllib,time 
logging.basicConfig(level=logging.DEBUG) 
log_time = time.strftime("%Y-%m-%d %H:%M:%S") 
logging.info("程序開始執行,%s",log_time) 
logging.info("從遠程API下載json,http://172.100.0.21:8080/patch/file/filelist",log_time) 
url = "http://172.100.0.21:8080/patch/file/filelist?date=2017-08-10" 
response = urllib.urlopen(url) 
data = json.loads(response.read())['data'] 
logging.info("測試下載結果,%s",log_time) 
with open("packet.sql","w") as F: 
    for i in data: 
     print("%s %s %s %s" %(type(str(i['time'])),type(str(i['patch_id'])),type(str(i['filename'])),type(str(i['server_ip'])))) 
     F.write("%s %s %s %s\n" %(str(i['time']),str(i['patch_id']),str(i['filename']),str(i['server_ip']))) 

但是當我試圖運行該腳本，我得到一個TypeError：

Traceback (most recent call last): 
    File "/usr/lib64/python2.6/logging/__init__.py", line 784, in emit 
    msg = self.format(record) 
    File "/usr/lib64/python2.6/logging/__init__.py", line 662, in format 
    return fmt.format(record) 
    File "/usr/lib64/python2.6/logging/__init__.py", line 444, in format 
    record.message = record.getMessage() 
    File "/usr/lib64/python2.6/logging/__init__.py", line 314, in getMessage 
    msg = msg % self.args 
TypeError: not all arguments converted during string formatting 

我已經它轉換爲格式字符串，爲什麼我收到：

TypeError: not all arguments converted during string formatting

當我刪除F.write

F.write("%s %s %s %s\n" %(str(i['time']),str(i['patch_id']),str(i['filename']),str(i['server_ip']))) 

這是正確的

Answer 1

的問題是在這條線：

logging.info("從遠程API下載json,http://172.100.0.21:8080/patch/file/filelist",log_time)

沒有在格式字符串爲log_time一個%s中被替換下場。刪除第二個參數，改變行：

logging.info("從遠程API下載json,http://172.100.0.21:8080/patch/file/filelist")

和文件可以正常運行。或者，在格式化字符串中添加說明符（如%s）。
