Question

我使用以下方法在我的PHPUnit测试中调度Slim应用程序的路径：

protected function dispatch($path, $method='GET', $data=array())
{
    // Prepare a mock environment
    $env = Environment::mock(array(
        'REQUEST_URI' => $path,
        'REQUEST_METHOD' => $method,
    ));

    // Prepare request and response objects
    $uri = Uri::createFromEnvironment($env);
    $headers = Headers::createFromEnvironment($env);
    $cookies = [];
    $serverParams = $env->all();
    $body = new RequestBody();

    // create request, and set params
    $req = new Request($method, $uri, $headers, $cookies, $serverParams, $body);
    if (!empty($data))
        $req = $req->withParsedBody($data);

    $res = new Response();

    $this->headers = $headers;
    $this->request = $req;
    $this->response = call_user_func_array($this->app, array($req, $res));
}

例如：

public function testGetProducts()
{
    $this->dispatch('/products');

    $this->assertEquals(200, $this->response->getStatusCode());
}

但是，响应中的状态代码和标题之类的内容，(string) $response->getBody()为空，因此我无法检查HTML中是否存在元素。当我在浏览器中运行相同的路径时，我得到了预期的HTML输出。另外，如果我echo $response->getBody(); exit;然后在浏览器中查看输出，我会看到HTML正文。有没有理由，我的实施，我在测试中没有看到这个？（在CLI中，我猜不同的环境）

在设置已解析的正文时，

$response->getBody()将为空。将它作为字符串放入RequestBody更容易，就像它通过电线进入时所设置的一样。

即是这样的：

protected function dispatch($path, $method='GET', $data=array())
{
    // Prepare a mock environment
    $env = Environment::mock(array(
        'REQUEST_URI' => $path,
        'REQUEST_METHOD' => $method,
        'CONTENT_TYPE' => 'application/json',
    ));

    // Prepare request and response objects
    $uri = Uri::createFromEnvironment($env);
    $headers = Headers::createFromEnvironment($env);
    $cookies = [];
    $serverParams = $env->all();
    $body = new RequestBody();
    if (!empty($data)) {
        $body->write(json_encode($data));
    }

    // create request, and set params
    $req = new Request($method, $uri, $headers, $cookies, $serverParams, $body);
    $res = new Response();

    $this->headers = $headers;
    $this->request = $req;
    $this->response = call_user_func_array($this->app, array($req, $res));
}

使用PHPUnit测试Slim 3路由时，$ response-＆gt; getBody（）为空
