Question

我在 Slim 中开发了简单的API，它存储在Online Server中。当我从浏览器检查它时它工作正常，但是当我从Iphone应用程序检索它时，它显示以下错误：

我尝试了很多，但一切都是徒劳的。如果有人遇到这个问题，或者知道这个问题，那么请指导我。提前谢谢。

我的代码如下：

公共/ index.php的

<?php
use \Psr\Http\Message\ServerRequestInterface as Request;
use \Psr\Http\Message\ResponseInterface as Response;

require '../vendor/autoload.php'; 

$app = new \Slim\App; 

//Questions Routes
require '../src/routes/questions.php';

$app->run();

路由/ questions.php

<?php
use \Psr\Http\Message\ServerRequestInterface as Request;
use \Psr\Http\Message\ResponseInterface as Response;

$app = new \Slim\App;

//Get All Questions
$app->get('/api/questions', function(Request $request, Response $response){

$questions = "All questions are retrieved successfully";     

        echo json_encode($questions);

});

// Get specific Questions
$app->get('/api/questions/{app_id}', function(Request $request, Response $response){

$questions = "Specific questions are retrieved successfully";    

echo json_encode($questions);

});

你应该把你的iOS代码放在这里。

从你的Slim，我会放置：

CustomData

在您的回复代码中，您可以添加此功能以提供所有客户响应：

$app->status($status_code);

用法非常简单：

function echoResponse($status_code, $response) {
    $app = \Slim\Slim::getInstance();
    // Http response code
    $app->status($status_code);
    // setting response content type to json    
    $app->contentType('application/json');
    echo json_encode($response);
}

从iOS的角度来看，没有代码就很难说些什么。
