SyntaxError:JSON.parse:JSON数据角度2的第1行第1列中的意外字符

问题描述:

当我将数据发布到服务器时,我在数据库中收到此错误语法错误:JSON.parse:JSON数据第1行第1列的意外字符[了解更多]",但是无论如何,数据仍然进入数据库.可能有什么错误?

When i post data to my server , i get this error in my database " SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data[Learn More]" but anyway the data still goes into the database. What could be there error?

服务器很可能返回了错误页面(无效的JSON),请在开发人员工具的网络"标签中检查响应.

Most probably server returned error page (which is not valid JSON), check response in network tab in developer tools.
