这个错误提示表明在使用 fastjson 库解析 JSON 字符串时,遇到了非法的输入。具体错误位于字符串的第一个字符,偏移量为 1。
要解决这个问题,你可以检查你提供给 fastjson 库的 JSON 字符串是否符合 JSON 格式的要求。确保字符串以正确的方式包含键值对、数组等表达式,并且使用双引号来引用字符串值。另外,还要注意转义特殊字符,如双引号、反斜杠等。
如果你能提供更多的代码和 JSON 字符串示例,我可以给出更具体的帮助。

com.alibaba.fastjson2.JSONException: illegal input, offset 1, char "
com.alibaba.fastjson2.JSONException: illegal input, offset 1, char "是由于JSON字符串格式错误导致的异常。具体来说,异常消息中的"illegal input"表示输入的JSON字符串存在非法字符或格式错误,"offset 1"表示错误出现在字符串的第一个字符位置。
有几个可能导致这个异常的原因:
1. JSON字符串中缺少冒号(:),例如键值对没有正确的分隔符。这可能是由于在JSON字符串中忘记添加冒号而导致的格式错误。
2. JSON字符串中存在额外的逗号(,)。在JSON对象或数组中,键值对或元素之间应该用逗号分隔,但是最后一个键值对或元素后面不能有逗号。
3. JSON字符串中存在非法的转义字符或特殊字符。在JSON字符串中,一些字符需要进行转义,例如双引号(")和反斜杠(\)。如果这些字符没有正确转义,就会导致格式错误。
为了解决这个问题,你可以检查你的JSON字符串是否符合JSON格式规范。确保每个键值对都有正确的冒号分隔符,去除不必要的逗号,并正确转义特殊字符。如果你仍然无法找到问题所在,可以尝试使用在线的JSON验证工具来验证你的JSON字符串是否有效。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
