请求接口后端提示：JSON parse error: Unrecognized token 'clickLocation': was expecting ('true', 'false' or 'null');

 内容：JSON parse error: Unrecognized token 'clickLocation': was expecting ('true', 'false' or 'null'); nested exception is com.fasterxml.jackson.core.JsonParseException: Unrecognized token 'clickLocation': was expecting ('true', 'false' or 'null')\n at [Source: (PushbackInputStream); line: 1, column: 15]

提示： JSON.parse error，所以是 json 的转化问题。

let obj = {
    clickLocation: "wx",
    clickOrigin: "wx"
}
$.ajax({

    dataType: "json",
    headers: {

    data: JSON.stringify(obj),
    async: false,
    success: function (res) {
        console.log(res, "res");
    }
