Question

如何使用分页从Web服务检索数据？现在我能够显示数据。但我不能做分页。我正在使用带有curl库的codeigniter 3.0.6。这就是我用来制作REST API的方法：

#topbar {
    width: 1080px;
    margin: 0 auto;
    height: 40px;
}
body {
    margin: 0;
    padding: 0;
    font-family: Helmet, Freesans, Helvetica, Arial, sans-serif;
    ;
}
#logo {
    margin-top: 8px;
    float: left;
    margin-right: 8px;
}
.border-part {
    float: left;
    height: 100%;
    border-left: 1px #CCCCCC solid;
}
#logo-image {
    width: 20px;
    margin: 12px;
    float: left;
}
.signin-text {
    margin: 14px;
    font-size: 90%;
    font-weight: bold;
    float: left;
}
#dash-image {
    padding-left: 50px;
    float: left;
    height: 40px;
}
#bell {
    margin: 8px;
    height: 28px;
    float: left;
}
.stuff-section {
    font-weight: bold;
    font-size: 90%;
    padding: 13px 15px 0 15px;
    height: 27px;
}
.seacher-border {
    float: left;
    height: 100%;
    border-left: 1px #CCCCCC solid;
    margin-left: 20px;
}
#search-box {
    margin: 10px;
    font-weight: bold;
    background-color: #E4E4E4;
    font-size: 14px;
    border: none;
    height: 24px;
    float: left;
}
#search-pic {
    position: relative;
    right: 10px;
    top: 10px;
    height: 25px;
}
#second-bar {
    background-color: #BB1919;
    width: 100%;
    height: 80px;
}
#newsbar {
    width: 1080px;
    margin: 0 auto;
    background-color: blue;
}
h1 {
    padding: 0;
    margin: 0;
 float;
}

这是检索数据：

function index_get($limit = 100, $offset = 0) {
    $MhswID = $this->get('MhswID');
    if ($MhswID == '') {
        $mhsw = $this->db->get('mhsw', $limit, $offset)->result();
    } else {
        $this->db->where('MhswID', $MhswID);
        $mhsw = $this->db->get('mhsw', $limit, $offset)->result();
    }
    $this->response($mhsw, 200);
}

尝试将函数名称更改为index_post

function index_post() {
    $limit = $this->post('limit'); 
    $offset = $this->post('offset');
    $MhswID = $this->post('MhswID');
    if ($MhswID == '') {
        $mhsw = $this->db->get('mhsw', $limit, $offset)->result();
    } else {
        $this->db->where('MhswID', $MhswID);
        $mhsw = $this->db->get('mhsw', $limit, $offset)->result();
    }
    $this->response($mhsw, 200);
}

并将api url更改为

function index($limit = 100, $offset = 0){
    $data['mahasiswa'] = json_decode($this->curl->simple_get($this->API.'/mahasiswa/index/', array('limit' => $limit, 'offset' => $offset));
    $this->load->view('welcome_message',$data);
}

您可以通过

查看api的响应

var_dump($this->curl->simple_get($this->API.'/mahasiswa/index'));

我想你必须在curl中传递REST api的用户名和密码。我不知道你使用的是哪个库，它必须在REST api库的文档中给出。
