[英]Upload File Api request works in postman but not in nodejs and react MERN
[英]Postman can upload file to a Node api. But Not with React
Redux代碼
export const uploadImage = data => async dispatch => {
const config = {
headers: {
"Content-Type": "multipart/form-data"
}
};
try {
const res = await axios.post("/api/profile/upload", data, config);
// const res = await axios.post("/api/profile/upload", data, {
// headers: {
// "Content-Type": "multipart/form-data"
// }
// });
console.log(res);
dispatch({
type: AVATAR_UPLOAD,
payload: res.data
});
} catch (err) {
const errors = err.response.data.errors;
if (errors) {
errors.forEach(error => dispatch(setAlert(error.msg, "danger")));
}
dispatch({
type: PROFILE_ERROR,
payload: { msg: err.response.statusText, status: err.response.status }
});
}
};
反應代碼
const data = new FormData();
data.append("file", avatar);
uploadImage(data);
我收到錯誤的請求消息,req.files 為空我嘗試使用 Postman 相同的配置上傳文件,似乎 api 有效,但無法使用 react formdata 上傳。
任何想法將不勝感激。 提前致謝
嘗試這樣做:
const formData = new FormData();
formData.append('file', file);
const res = await axios.post("/api/profile/upload", formData, config);
