如何在select 2的ajax请求中添加主体？

$('#mySelect').select2({
  ajax: {
    url: 'https://example.com/api',
    dataType: 'json',
    type: 'POST',
    data: function(params) {
      return {
        searchTerm: params.term,
        page: params.page,
        // 添加主体数据
        bodyData: {
          key1: value1,
          key2: value2
        }
      };
    },
    processResults: function(data) {
      // 处理返回的结果
      return {
        results: data.items
      };
    }
  }
});

$('#mySelect').select2({
  ajax: {
    url: 'https://example.com/api',
    dataType: 'json',
    type: 'POST',
    data: {
      searchTerm: function(params) {
        return params.term;
      },
      page: function(params) {
        return params.page;
      },
      // 添加主体数据
      bodyData: {
        key1: value1,
        key2: value2
      }
    },
    processResults: function(data) {
      // 处理返回的结果
      return {
        results: data.items
      };
    }
  }
});
