1.报错:
JSON parse error: Unrecognized token 'undefined': was expecting ('true', 'false' or 'null'); nested exception is com.fasterxml.jackson.core.JsonParseException: Unrecognized token 'undefined': was expecting ('true', 'false' or 'null') at [Source: java.io.PushbackInputStream@655a8572; line: 1, column: 11]
2.分析:
很明显是json转换出问题,所以把问题范围限制在了前端。
3.处理:
使用JSON.Stringfy()将JavaScript 值转换为 JSON 字符串传到后台,报错解决。
