A JSONObject text must begin with '{'

as the opening curly brace represents the start of the object. It is a required syntax for creating a valid JSONObject in JSON format. Any other character, including whitespace or comments, before the opening brace will result in an error. Additionally, the closing curly brace '}' must also be included at the end of the object to indicate its completion.

这个错误提示意味着你的 JSON 文本在位置 1 的第 2 个字符处没有以 '{' 开头。在 JSON 中，一个有效的对象必须以 '{' 开始。请确保你的 JSON 文本的开头是以 '{' 开始的，并检查是否有任何语法错误或其他格式问题。如果你可以提供更多的 JSON 代码或上下文，我可以给出更具体的建议。

the string

This error occurs when trying to parse a JSON string that does not begin with a '{' character at the expected position. The error message indicates that the issue is at character 12 of the string, which suggests that the string may have some invalid characters or formatting before the expected '{' character.

To resolve this error, you should check the JSON string for any formatting errors or invalid characters. Make sure that the string begins with a '{' character and that all opening and closing brackets are properly matched. You can also use a JSON validator or parser tool to help identify any issues with the JSON string.
