在执行发布请求并将数据保存在 db.json 后，如何在“json-server”api 提供的假 REST API 中取回 json

如何解决在执行发布请求并将数据保存在 db.json 后，如何在“json-server”api 提供的假 REST API 中取回 json

我用来将数据保存到我的 db.json 的代码，json 值是 axios.post 调用的第二个参数：

 axios.post(url,{ 
               "fullName":departmentName,"shortName":abbreviation,"hodFirstName":firstName,"hodMiddleName":middleName,"hodLastName":lastName,"hodEmail":email,"hodPhoneNumber":phoneNumber 
            }).then(res => {
               const data = res.data;
               console.log(data);
                  if(data.success){
                     setServerSuccessMessage(`${departmentName} department created successfully. Create another one?`);
                     
                  }else{
                     if(data.message.fullName) setfullNameErrorMessage(data.message.fullName)
                     if(data.message.shortName) setShortNameErrorMessage(data.message.shortName)
                     if(data.message.hodEmail) setEmailErrorMessage(data.message.hodEmail)
                     if(data.message.hodPhoneNumber) setPhoneNumberErrorMessage(data.message.hodPhoneNumber)
                     if(data.message.hodFirstName) setFirstNameErrorMessage(data.message.hodFirstName)
                     if(data.message.hodLastName) setLastNameErrorMessage(data.message.hodLastName)
                  }
            
               })
               .catch(err => {
                  console.log(err);
                  setServerErrorMessage("Something went wrong...")

                  
               })

上面代码中返回的 res json 应该是：

{
  "departments": [
    {
      "success":true,"message":{
        "fullName":"Software","shortName":"Se","hodEmail":"[e-mail]","hodPhoneNumber":"68444","hodFirstName":"Robin","hodLastName":"Hood"
                
                }
    }
  ]
}

当我这样做时，数据已保存，但我无法返回响应 json。
