我有一个使用 jquery 上传的 ajax 文件。它总是显示您所请求的操作是不允许的。添加了帮助程序数组 html、url、文件、表单。我尝试了很多方法，但得到了相同的结果。
这是我的代码
Controller 函数
function demo() {
$this->load->view('file_upload_ajax', NULL);
}
function upload_file() {
//upload file
$config['upload_path'] = 'uploads/';
$config['allowed_types'] = '*';
$config['max_filename'] = '255';
$config['encrypt_name'] = TRUE;
$config['max_size'] = '1024'; //1 MB
echo $_FILES['file']['name'];
if (isset($_FILES['file']['name'])) {
if (0 < $_FILES['file']['error']) {
echo 'Error during file upload' . $_FILES['file']['error'];
} else {
if (file_exists('uploads/' . $_FILES['file']['name'])) {
echo 'File already exists : uploads/' . $_FILES['file']['name'];
} else {
$this->load->library('upload', $config);
if (!$this->upload->do_upload('file')) {
echo $this->upload->display_errors();
} else {
echo 'File successfully uploaded : uploads/' . $_FILES['file']['name'];
}
}
}
} else {
echo 'Please choose a file';
}
}
查看文件:file_upload_ajax.php
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<script src="<?php echo base_url().'js'?>/beep.js"></script>
</head>
<body>
<p id="msg"></p>
<input type="file" id="file" name="file" />
<button id="upload">Upload</button>

$(document).ready(function() {
$('#upload').on('click', function () {
var file_data = $('#file').prop('files')[0];
var form_data = new FormData();
form_data.append('file', file_data);
$.ajax({

dataType: 'text',

success: function (response) {
$('#msg').html(response); // display success response from the server
},
error: function (response) {
$('#msg').html(response); // display error response from the server
}
});
});
});

请帮助我在此先感谢。
最佳答案
如果 $config['csrf_protection'] = TRUE，请检查您的 config.php； 如果它设置为 true，则需要使用 ajax 请求发送 csrf token 。
将此添加到您的 View 页面。
<input type="hidden" id="hidCSRF" name="<?php echo $this->security->get_csrf_token_name(); ?>" value="<?php echo $this->security->get_csrf_hash(); ?>">
在您的 js 文件中进行以下更改。
$(document).ready(function() {
$('#upload').on('click', function () {
var _csrfName = $('input#hidCSRF').attr('name');
var _csrfValue = $('input#hidCSRF').val();
var file_data = $('#file').prop('files')[0];
var form_data = new FormData();
form_data.append('file', file_data);
form_data.append(_csrfName, _csrfValue);
$.ajax({
url: base_url +"beep/upload_file",
dataType: 'text',
cache: false,
contentType: false,
processData: false,
data: form_data,
type: 'post',
success: function (response) {
$('#msg').html(response); // display success response from the server
},
error: function (response) {
$('#msg').html(response); // display error response from the server
}
});
});
});
关于javascript - 使用 Codeigniter 上传 AJAX 文件，jQuery 将响应显示为 "The action you have requested is not allowed"，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/42851468/
