React code for build jsonBlob object
function jsonBlob(obj) {
return new Blob([JSON.stringify(obj)], {
type: "application/json",
});
}
exportFTP = () => {
const formData = new FormData();
formData.append("file", jsonBlob(this.state.ipData));
alert("Logs export to FTP server")
axios({
method: "post",
url: "http://localhost:8080/api/auth/uploadfiles",
data: formData,
headers: {
Accept: "application/json ,text/plain, */*",
"Content-Type": "multipart/form-data",
},
});
};
Spring boot backend that accepts for frontend request
public class UploadFile {
@Autowired
private FTPClient con;
@PostMapping("/api/auth/uploadfiles")
public String handleFileUpload(@RequestParam("file") MultipartFile file) {
try {
boolean result = con.storeFile(file.getOriginalFilename(), file.getInputStream());
System.out.println(result);
} catch (Exception e) {
System.out.println("File store failed");
}
return "redirect:/";
}
I want to figure out when I called the function from the frontend it's working properly but I change the state its doesn't send the object to the backend while the file appears in the directory. if I delete the file then only send it again and save it on the directory. How I save multiple files while doesn't delete the previous ones
Thank you very much for your time and effort.
In React application I used props to pass the file name from a different state and make sure to remove,
"Content-Type": "multipart/form-data",
Main function in React,
exportFTP = ({props from different state}) => {
const formData = new FormData();
formData.append("file", jsonBlob(this.state.ipData),{You can use this parm for pass name});
alert("Logs export to FTP server")
axios({
method: "post",
url: "http://localhost:8080/api/auth/uploadfiles",
data: formData,
headers: {
Accept: "application/json ,text/plain, */*"
},
});
};
And back end code I used same to get the original name then Its appears with the right name.
con.storeFile(file.getOriginalFilename(), file.getInputStream());
Chears !!
