我有3个图像或多个图像阵列，其总大小约为。 29mb或以上。我尝试使用带有表单数据的Ajax在服务器端发布它。但是当我尝试在MVC中使用FormData发布大数据时，它显示错误是否有任何解决方案。当我尝试发布数据时，它在客户端显示错误意味着进入request.fail部分
这是我的Jquery代码
var filess = new Array();
var num = 4;
var IsAlready = false;
$(document).ready(function() {
document.getElementById('pro-image').addEventListener('change', readImage, false);
$( ".preview-images-zone" ).sortable();
$(document).on('click', '.image-cancel', function() {
debugger;
let no = $(this).data('no');
let Id = this.id;
$(".preview-image.preview-show-"+no).remove();
for (var i = 0; i < filess.length; i++) {
debugger;
filess = $.grep(filess, function(value) {
return value.name != Id;
});
}
});
});
function readImage() {
if (window.File && window.FileList && window.FileReader) {
var files = event.target.files;
var output = $(".preview-images-zone");
for (var i = 0; i < files.length; i++) {
$.grep(filess, function (n) {
if (n.name == files[i].name) {
IsAlready = true;
}
})
if (IsAlready)
{
alert("Same Name File Exist");
$("#pro-image").val('');
IsAlready = false;
return false;
}
}
var anyWindow = window.URL || window.webkitURL;
for (var i = 0; i < files.length; i++) {
filess.push(files[i]);
var file = null;
file = files[i];
if (!file.type.match('image')) continue;
var objectUrl = anyWindow.createObjectURL(files[i]);
var html = '<div class="preview-image preview-show-' + num + '" >' +
'<div class="image-cancel" data-no="' + num + '" id="' + files[i].name + '">x</div>' +
'<div class="image-zone"><img id="pro-img-' + num + '" src="' + objectUrl + '"></div>' +
'</div>';
output.append(html);
num = num + 1;
window.URL.revokeObjectURL(files[i]);
}
$("#pro-image").val('');
}
else {
console.log('Browser not support');
}
}
$("#submit").click(function () {
event.preventDefault();
debugger;
var url = "/Administration/CreateAlbum";
var albumName = $("#AlbumName").val();
var albumDescription = $("#AlbumDescription").val();
var IsActive = $("#IsActive").val();
var filess = new Array();
var data = new FormData();
data.append('albumName', albumName);
data.append('albumDescription', albumDescription);
data.append('IsActive', IsActive);
$("#submit").prop("disabled", true);
for (var i = 0; i < filess.length; i++) {
data.append('image', filess[i] );
}
var request = $.ajax({
url: url,
enctype: 'multipart/form-data',
type: 'POST',
processData: false,
contentType: false,
cache: false,
timeout: 600000,
data: data
});
request.done(function (response) {
$("#resultCode").html(response.ResultCode);
$("#resultMessage").html(response.ResultMessage);
$('#reasonCode').val("");
$('#quantity').val("");
$('#inventoryCode').val("");
$('#unitCost').val("");
});
request.fail(function (jqXHR, textStatus) {
alert("Request failed: " + textStatus);
});
});

用于大文件上传。
ini_set（＆＃39; upload_max_filesize＆＃39;，＆＃39; 10M＆＃39;）; ini_set（＆＃39; post_max_size＆＃39;，＆＃39; 10M＆＃39;）;
您的files数组为空，无需指定enctype。这里是Ajax
var files = array();
如果你有多个文件，那么追加
data.append('image[]', filess[i] );
var filess = new Array();
var num = 4;
var IsAlready = false;
$(document).ready(function() {
document.getElementById('pro-image').addEventListener('change', readImage, false);
$( ".preview-images-zone" ).sortable();
$(document).on('click', '.image-cancel', function() {
debugger;
let no = $(this).data('no');
let Id = this.id;
$(".preview-image.preview-show-"+no).remove();
for (var i = 0; i < filess.length; i++) {
debugger;
filess = $.grep(filess, function(value) {
return value.name != Id;
});
}
});
});
function readImage() {
if (window.File && window.FileList && window.FileReader) {
var files = event.target.files;
var output = $(".preview-images-zone");
for (var i = 0; i < files.length; i++) {
$.grep(filess, function (n) {
if (n.name == files[i].name) {
IsAlready = true;
}
})
if (IsAlready)
{
alert("Same Name File Exist");
$("#pro-image").val('');
IsAlready = false;
return false;
}
}
var anyWindow = window.URL || window.webkitURL;
for (var i = 0; i < files.length; i++) {
filess.push(files[i]);
var file = null;
file = files[i];
if (!file.type.match('image')) continue;
var objectUrl = anyWindow.createObjectURL(files[i]);
var html = '<div class="preview-image preview-show-' + num + '" >' +
'<div class="image-cancel" data-no="' + num + '" id="' + files[i].name + '">x</div>' +
'<div class="image-zone"><img id="pro-img-' + num + '" src="' + objectUrl + '"></div>' +
'</div>';
output.append(html);
num = num + 1;
window.URL.revokeObjectURL(files[i]);
}
$("#pro-image").val('');
}
else {
console.log('Browser not support');
}
}
$("#submit").click(function () {
event.preventDefault();
debugger;
var url = "/Administration/CreateAlbum";
var albumName = $("#AlbumName").val();
var albumDescription = $("#AlbumDescription").val();
var IsActive = $("#IsActive").val();
var filess = new Array();
var data = new FormData();
data.append('albumName', albumName);
data.append('albumDescription', albumDescription);
data.append('IsActive', IsActive);
$("#submit").prop("disabled", true);
for (var i = 0; i < filess.length; i++) {
data.append('image', filess[i] );
}
var request = $.ajax({
url: url,
enctype: 'multipart/form-data',
type: 'POST',
processData: false,
contentType: false,

request.done(function (response) {
$("#resultCode").html(response.ResultCode);
$("#resultMessage").html(response.ResultMessage);
$('#reasonCode').val("");
$('#quantity').val("");
$('#inventoryCode').val("");
$('#unitCost').val("");
});
request.fail(function (jqXHR, textStatus) {
alert("Request failed: " + textStatus);
});
});

如上所述，您需要在web.config
中设置maxAllowedContentLength <system.webServer>
<security>
<requestFiltering>
<requestLimits maxAllowedContentLength="YOUR SIZE" />
</requestFiltering>
</security>
</system.webServer>
