Problem solving for put request not getting parameters in CodeIgniter restserver

Recently encountered an egg ache problem with restserver, found that $this->put get parameters are null. Check it out. This seems to be a common problem, see Links: https://github.com/chriskacerguis/codeigniter-restserver/issues/362

Let's take a look at the official explanation: see http://code.tutsplus.com/tutorials/working-with-restful-services-in-codeigniter-2--net-8814

$this->put () Reads in put arguments set in the HTTP headers or via CURL.

That is, the function can read the put parameter that is carried when accessed through curl, or the parameter in the HTTP headers. But after testing, even if the parameter is put in headers, $this->put () can not access, the root cause may be in the source of a place to shield. Zajia has not found a solution to the basic method, but the following two can temporarily solve the problem:

1, consistent with post, still pass parameters in body. Write a function in the base class:

    Public Function Getput ($key) {        return $this->input->input_stream ($key);    }

When the client accesses the normal parameters in the body, it is OK. Note that this time through $this->post () is not obtained parameters, must be taken from the Input_stream. The above function supports simultaneous fetching of multiple fields, such as:

$data = $this->getput (The Array (' Tel ', ' name ', ' addr '));

In fact, the function from input in CI should support multiple fields simultaneously, but Restserver's This->get () post () is not supported.

Add: When the parameters are placed in the body, directly with $this->put () can be obtained to the corresponding field, the document is said to be in the headers, is actually in the body! However, $this->put () does not support multiple fields, so the above function is meaningful.

$this->delete () also have this problem, can not read the parameters in the headers, but to read the body of!!!

2, the parameter is passed in the header, the base class writes a function:

    /**     * Get header corresponding to key     * @param $key     * @return Mixed     *    /Public Function GetHeader ($key) {        return $this->input->get_request_header ($key, TRUE);    }

Personal recommendation the first kind of Kazakhstan, the parameters in the body pass! The best way to follow the HTTP rules, don't suck in the header.

The problem with the Ps:restserver put parameter is not related to the Content-type:application/json setting.
