我现在遇到CodeIgniter的问题：我使用
REST Controller library(这真的很棒)来创建API但是我无法获得PUT请求…
这是我的代码：
function user_put() {
$user_id = $this->get("id");
echo $user_id;
$username = $this->put("username");
echo $username;
}
我使用curl来发出请求：
curl -i -X PUT -d "username=test" http://[...]/user/id/1
user_id已满,但username变量为空.然而它适用于动词POST和GET.
你有什么想法吗？
谢谢 ！
根据：
http://net.tutsplus.com/tutorials/php/working-with-restful-services-in-codeigniter-2/我们应该咨询
https://github.com/philsturgeon/codeigniter-restserver/blob/master/application/libraries/REST_Controller.php#L544,看看这个方法：
原文链接：https://www.f2er.com/php/137709.html/**
* Detect method
*
* Detect which method (POST,PUT,GET,DELETE) is being used
*
* @return string
*/
protected function _detect_method() {
$method = strtolower($this->input->server('REQUEST_METHOD'));
if ($this->config->item('enable_emulate_request')) {
if ($this->input->post('_method')) {
$method = strtolower($this->input->post('_method'));
} else if ($this->input->server('HTTP_X_HTTP_METHOD_OVERRIDE')) {
$method = strtolower($this->input->server('HTTP_X_HTTP_METHOD_OVERRIDE'));
}
}
if (in_array($method,array('get','delete','post','put'))) {
return $method;
}
return 'get';
}
看看我们是否定义了HTTP标头HTTP_X_HTTP_METHOD_OVERRIDE,它使用它来支持我们在网络上实现的实际动词.要在请求中使用它,您将指定标头X-HTTP-Method-Override：方法(因此X-HTTP-Method-Override：put)以生成自定义方法覆盖.有时框架需要X-HTTP-Method而不是X-HTTP-Method-Override,因此这会因框架而异.
如果你是通过jQuery做这样的请求,你会把这个块集成到你的ajax请求中：
beforeSend: function (XMLHttpRequest) {
//Specify the HTTP method DELETE to perform a delete operation.
XMLHttpRequest.setRequestHeader("X-HTTP-Method-Override","DELETE");
}
