I have a project containing a JSP page. I want it to have a file uploading form which it should post to a API which will process it . I am uploading it through
<form action="api/processExcel" method="post" enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file"><br>
<input type="submit" name="submit" value="Submit">
<input type="hidden" name="${_csrf.parameterName}" value="${_csrf.token}" />
</form>
when I remove enctype="multipart/form-data" it's working fine but as soon as I put it there and recompile and run the project this error shows up:
Invalid CSRF Token 'null' was found on the
request parameter '_csrf' or header 'X-CSRF-TOKEN'.
I also need to know the place where the file gets uploaded . Is there a default location where it gets uploaded or we need to specify it ?
When i do this
` try {
http
.csrf().disable();
// .authorizeRequests()
// .antMatchers("/static/**").permitAll()
// .antMatchers("/settings/api/**").permitAll()
// .antMatchers("/api/**").permitAll()
// .anyRequest().authenticated()
// .and()
// .formLogin()
// .loginPage("/login").permitAll()
// .defaultSuccessUrl("/index",true) ;
}`
and disable csrf it starts working fine .
