我有这个问题。我使用JQuery中的ajax来调用CodeIgniter控制器中的函数。但我总是得到400 Bad Request错误,即使我只是从函数打印纯文本。
以下是代码:
class Prueba extends CI_Controller {
//Displays de page, the code here is irrelevant
public function index(){
$this->validar_sesion();
$ciclos= $this->recuperar_periodos_escolares();
$this->smartyci->assign('secciones', $this->session->userdata('secciones'));
$this->smartyci->assign('modulos', $this->session->userdata('modulosAutorizados'));
$this->smartyci->assign('ciclos',$ciclos);
$this->smartyci->display('v3/reportes/reporte_ranking_general.tpl');
}
//The function to be called with AJAX, it originally has more code,
//but for the tests I just echoed a plain string, which is never returned.
public function recuperar_instrumentos(){
echo "EXITO!";
}
这是javascript:
var url="148.209.25.135/evaluacionAdmin/index.php/prueba;";
function recuperar_instrumentos(idCicloEscolar){
var request=$.ajax({
type:"POST",
url:url,
data:{idCiclo:idCicloEscolar}
});
request.done(function(data){
$('#instrumento').html(data);
});
request.fail(function(xhr,textStatus,error){
$('#instrumento').html(xhr.responseText);
alert("status= "+textStatus+"\nerror= "+xhr.status+"\n"+error);
});
我总是得到这个回应
jqXHR.responseText:
An Error Was Encountered
The URI you submitted has disallowed characters.
jqXHR.status: 400
textStatus: error
error: Bad request
对于那里发生的任何暗示或帮助都将非常感激

var url="148.209.25.135/evaluacionAdmin/index.php/prueba;";
在网址中有一个半冒号。将其更改为:
var url="148.209.25.135/evaluacionAdmin/index.php/prueba";
标准CI配置具有URI的允许字符列表。您可以修改正则表达式以接受半冒号,但在这种情况下,看起来您偶然将那个半冒号放在那里。

问题出在您的网址中
var url="148.209.25.135/evaluacionAdmin/index.php/prueba;";
应该是
var url="148.209.25.135/evaluacionAdmin/index.php/prueba";// delete extra semicolon
