我正在做一个get方法，当我运行代码时，我得到了这个没有尝试加载JSON数据，因为请求的Content-Type不是'application/json'.。我尝试设置标题。这是我的代码。

<template>
   <div class="container">
     <button @click="SearchTown"> Search Town </button>

   </div>
</template>

<script>
import axios from 'axios';
export default {
        name: 'SearchTown',
        props: {
            messege: String
        },
  data(){
    return{
      search: [],
    }
    
    },

  methods :{
      SearchTown() {
    axios
      .get('https://david.darwinist.io/proxy/5000/town/',{headers:{'content-type':'application/json'}})
     .then((response) => {// checking response in the console
            console.log(response.data)})
      .catch((error)=>{
        console.log(error)
      })
  }
 }
}

</script>

            .where(County.name == town_dict["county"])
            .where(Town.name == town_dict["name"])
            ).one()
        town_county = copy.copy(town).__dict__
        del town_county["_sa_instance_state"]
        town_county["county"] = town.county.name
        town_county["nation"] = town.county.nation.name
