大家好，以上是我的first.txt文件中每個數據塊的格式。 我想閱讀並將其更改為類似於以下格式的json格式，並將其存儲到second.txt文件中。

def convert_to_json(path, name, username, post, link, replies, retweets, likes, retweetby, date, domainname):
with open(path, 'a') as file:
    stringData = [{"ContentUrl": link,
    "Text": post,
    "PublishDate": date.strip(),
    "Title": "",
    "SourceUrl": domainname,
    "SocialNetwork": media,
    "Source": "",
    "Author": name,
    "Like_count": likes.strip(),
    "Replies_count": replies.strip(),
    "Retweets_count": retweets.strip(),
    "Schema": "SOCIAL_MEDIA"}]

    objData = json.load(stringData)
    file.write(stringData)

上面的代碼假定要接收數據，然后將其附加到second.txt文件中。 但是，我的代碼無法將我想要的數據追加到我的second.txt文件中。 控制台上沒有顯示任何明顯的錯誤，我在這里尋求所有專家的建議和幫助。

Answer 1

您沒有正確使用json.load ； 嘗試這樣：

record = {"ContentUrl": link,
    "Text": post,
    "PublishDate": date.strip(),
    "Title": "",
    "SourceUrl": domainname,
    "SocialNetwork": media,
    "Source": "",
    "Author": name,
    "Like_count": likes.strip(),
    "Replies_count": replies.strip(),
    "Retweets_count": retweets.strip(),
    "Schema": "SOCIAL_MEDIA"}  

with open(path, 'a') as file:
    objData = json.load(file)
    objData.append(record)
    file.write(json.dumps(objData))

Answer 2

1. 試試json.dumps而不是load
2. 為什么將字典存儲在列表中？

3. 將json.dumps的結果而不是對象寫入文件

    with open(path, 'a+') as file: stringData = {"ContentUrl": link, "Text": post, "PublishDate": date.strip(), "Title": "", "SourceUrl": domainname, "SocialNetwork": media, "Source": "", "Author": name, "Like_count": likes.strip(), "Replies_count": replies.strip(), "Retweets_count": retweets.strip(), "Schema": "SOCIAL_MEDIA"} objData = json.dumps(stringData) file.write(objData) 

Answer 3

將所有數據添加到列表（ stringData ），最后使用以下命令將stringData寫入第二個文件

stringData = [] #init

def addToDataToBeWritten(path, name, username, post, link, replies, retweets, likes, retweetby, date, domainname):    

    row = {"ContentUrl": link,
    "Text": post,
    "PublishDate": date.strip(),
    "Title": "",
    "SourceUrl": domainname,
    "SocialNetwork": media,
    "Source": "",
    "Author": name,
    "Like_count": likes.strip(),
    "Replies_count": replies.strip(),
    "Retweets_count": retweets.strip(),
    "Schema": "SOCIAL_MEDIA"}
    stringData.append(raw)

''' Read and call the method here'''
with open(path, 'w') as file:  
    file.write(json.dumps(stringData))
