У меня есть POST API, который при выполнении должен отобразить результат ответа в div. Я использую React.js и Redux
Это служба, в которой хранится API
const addMP3Request = async (payload) => {
const formData = new FormData();
formData.append("titre",payload.payload.titre);
formData.append("description",payload.payload.description);
formData.append("type",payload.payload.type);
formData.append("file1",payload.payload.fichier1);
const wsResponse = await axios.request({
method: 'post',
url: `http://localhost:3000/api/watson_tones/analyzeMP3`,
data: formData,
config: {
headers: {
'Content-Type': `multipart/form-data`,
'Accept': 'application/json',
}
}
});
return wsResponse;
}
это мой редуктор
const INIT_STATE = {
responseData: ''
};
export default (state = INIT_STATE, action) => {
switch (action.type) {
case ADD_MP3: {
return {
...state,
responseData: action.responseData
}
}
default:
return state;
}
}
это действие:
export const addMP3Action = (titre,description,type,fichier1) => {
return {
type: ADD_MP3,
payload: {
titre: titre,
description: description,
type: type,
fichier1:fichier1
},
};
};
и это представление, где я добавляю MP3 и хочу сохранить ответ этого API

Когда я console.log(this.props.responseData) я получаю неопределённость. У вас есть идеи?
