json.decoder.JSONDecodeError:打开json文件时应为值：第1行第1列（字符0）

Question

我正在尝试使用flask创建博客页面，我想将输入文件作为我创建的config.json。请帮助我，我得到json解码器错误 我还试图将str转换为utf8，但它显示了错误

with open('config.json', 'r', encoding ='utf-8') as c:
    params = json.load(c)["params"]

json内容：

{
    "params":
    {
        "local_server":"True",
        "local_uri":"mysql://root:@localhost/codingthunder",
        "prod_uri":"mysql://root:@localhost/codingthunder",
        "fb_url":"https://facebook.com/codingthunder",
        "tw_url":"https://twitter.com/codingthunder",
        "gh_url":"https://github.com/codingthunder",
        "blog_name":"Coding Thunder",
        "tag_line":"A Blog liked by Programmers"
    }
}

输出日志：

json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

Answer 1

Expecting value: line 1 column 1 (char 0)提示文件开头没有值，因此解析文件中没有内容

这可能意味着

• 文件是空的
• 您打开的文件错误或不存在
• 您使用的是相对路径，而您的工作目录是错误的（例如，您在其中执行程序的目录）
