当我发出发布请求时，React Native返回[未处理的承诺拒绝：TypeError：网络请求失败]

Question

[当我在带有Axios的React Native中发出发布请求时，它返回[未处理的承诺拒绝：TypeError：网络请求失败]。这是我的json和axios方法

const credentials= {
NickName: "ricardo.luna",
Password: "123",
AccesoAplicacion: 1,
DerechosRangoInicial: 1000,
DerechosRangoFinal: 1012
}

const loginAxios = () => {
axios
  .post('x.x.x.x/API/users', credentials)
  .then(response => {
    console.log(response.IdUser);
  });
 };

Answer 1

只需在.then（）.catch(error=>{})之后添加以处理拒绝并捕获返回的错误

Answer 2

您需要将您的发布参数传递为FormData

let bodyFormData = new FormData();

bodyFormData.set('NickName', 'Fred');
bodyFormData.set('Password', '123');
bodyFormData.set('AccesoAplicacion', 1);
bodyFormData.set('DerechosRangoInicial', 1000);
bodyFormData.set('DerechosRangoFinal', 1012);
