大家好，以上是我的first.txt文件中每个数据块的格式。我想阅读它并将其更改为如下所示的json格式，并将其存储到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)

上面的代码假设接收数据然后将其附加到second.txt文件。但是，我的代码无法将我想要的数据附加到我的second.txt文件中。控制台没有显示明显的错误，我在这里寻求所有专家的建议和帮助。

Answer 1

您没有正确使用json.load;试试这样：

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

尝试json.dumps而不是加载
为什么要在列表中包装dict？

写入文件json.dumps的结果，而不是对象

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

将所有数据添加到列表（stringData），最后使用

将stringData写入第二个文件

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))
