axios預設傳送post請求時候引數是json形式傳遞到後臺，後臺(SpringMvc)需要透過添加註解@RequestBody對映到物件的方式來接收，後臺開發人員認為我就2個引數，懶得再封裝個物件了，讓前端同事直接透過表單的形式傳遞。於是就有了如下解決辦法：

const form = new FormData();

form.append("username", this.username);

form.append("password", this.password);

form.append("rememberMe", this.rememberMe+"");

const data = await instance.post("/auth/authorize", new URLSearchParams(form));

axios

.post(process.env.BASE_API_LOGIN + "/auth/authorize", new URLSearchParams(form))

.then(function (response) {

console.log(response.data);

});
