The reason for this exception is that the format of the passed parameter jsonarray is not correct. I printed the following jsonarray format:

[{"name":"hui1","salary":10000.39982635574,"age":8},
{"name":"hui2","salary":10000.160206564933,"age":11},
{"name":"hui3","salary":10000.417013742277,"age":28},
{"name":"hui4","salary":10000.26786620842,"age":7}]

The correct format here should be as follows:

{"name":"hui1","salary":10000.39982635574,"age":8}

Even if the original “[” switch jsonarray “[” is changed to this:

{"name":"hui1","salary":10000.39982635574,"age":8},
{"name":"hui2","salary":10000.160206564933,"age":11},
{"name":"hui3","salary":10000.417013742277,"age":28},
{"name":"hui4","salary":10000.26786620842,"age":7}

It’s also a mistake
