我正在尝试使用laravel 5.2中的ajax上传图像。但是我仍然在路由中收到错误500内部服务器错误。 当我尝试使用ajax请求上传图像时,浏览器显示正确的路径路径,但我仍然没有理由为什么它仍然向我显示错误。
HTML
<!-- CHANGE AVATAR TAB -->

<!-- END CHANGE AVATAR TAB -->
路线
Route::group(['prefix' => 'admin'], function ()
{
Route::controller('/','DashboardController');
});
的Ajax
$(document).on('click', '#updatepicture', function($e)
{
$e.preventDefault();
// send an ajax request
$("#error_image").empty();
$.ajax(
{
url: 'avatar',
processData: false,
contentType: false,
type: "post",//use for update
data: new FormData($("#updateprofileimage")[0]),
success: function(data)
{
if(data.status)
{
$("#uploadimagediv").html('<div class="alert alert-success"><button type="button" class="close">×</button>'+data.message+'</div>');
window.setTimeout(function()
{
$(".alert").fadeTo(500, 0).slideUp(500, function()
{
$(this).remove();
});
}, 5000);
$('.alert .close').on("click", function(e)
{
$(this).parent().fadeTo(500, 0).slideUp(500);
});
//console.log(data);
//$("#updateprofileimage")[0].reset();
//window.location.href = "http://localhost/laravel/admin/profile";
}
else
{
errors = data.errors;
for(error in errors)
{
$("#error_"+error.title).html(error.message);
}
}
},
error: function(xhr)
{
if(xhr.status == 422)
{
errors = xhr.responseJSON;
for(error in errors)
{
$("#error_"+error).html(errors[error][0]);
}
}
}
});
});
错误是:“NetworkError:500内部服务器错误 - http://localhost/laravel/admin/avatar”
请建议我哪里出错了。
控制器
public function postAvatar(ImageUploadRequest $request)

在您的ajax设置中,您必须为请求提供x-csrf-token。对于您的ajax请求,您的网址也存在问题:
$(document).on('click', '#updatepicture', function($e)
{
$e.preventDefault();
// send an ajax request
$("#error_image").empty();
$.ajax(
{
url: "{{url('avatar')}}",
processData: false,
contentType: false,
type: "post",//use for update
data: new FormData($("#updateprofileimage")[0]),
headers: {
'X-CSRF-TOKEN': "{{ csrf_token() }}"
},
success: function(data)
{
if(data.status)
{
$("#uploadimagediv").html('<div class="alert alert-success"><button type="button" class="close">×</button>'+data.message+'</div>');
window.setTimeout(function()
{
$(".alert").fadeTo(500, 0).slideUp(500, function()
{
$(this).remove();
});
}, 5000);
$('.alert .close').on("click", function(e)
{
$(this).parent().fadeTo(500, 0).slideUp(500);
});
//console.log(data);
//$("#updateprofileimage")[0].reset();
//window.location.href = "http://localhost/laravel/admin/profile";
}
else
{
errors = data.errors;
for(error in errors)
{
$("#error_"+error.title).html(error.message);
}
}
},
error: function(xhr)
{
if(xhr.status == 422)
{
errors = xhr.responseJSON;
for(error in errors)
{
$("#error_"+error).html(errors[error][0]);
}
}
}
});
});
