Question

编写API来处理XML和JSON。我希望响应采用请求使用的格式。

示例 - API请求标头包含：Accept: application/xml

问题是响应始终为Content-Type: application/json。

我希望此返回Content-Type: application/xml

这是代码：

public function setHeaders() {
    $headerType = $this->app->request->headers->get('Accept');
    switch($headerType){
        case "application/xml":
            $this->app->response->headers->set("Content-Type",'application/xml');
        default:
            // default type is application/json
            $this->app->response->headers->set("Content-Type",'application/json');
    }
}

# 404 errors
$app->notFound(function () use ($app) {
    $logMessage = sprintf("404 Not Found: URI: %s", $app->request->getPath());
    $app->log->debug($logMessage);

    $error = new \SMSTester\ErrorVO(2,"Request doesn\'t exist, check the manual.");
    $app->parser->setHeaders();
    $app->halt(404,$app->parser->outputParse($error));
});

outputParse返回以下字符串：

<xml>
    <error>true</error>
    <errorType>Request doesn\'t exist, check the manual.</errorType>
    <errorMessage>2</errorMessage>
</xml>

Answer 1

问题是，在正确的案例触发后，您没有使用break退出switch（假设$headerType实际设置为application/xml）所以你的default案件最终也会运行并恢复第一个案件所做的任何更改。

public function setHeaders() {
    $headerType = $this->app->request->headers->get('Accept');
    switch($headerType){
        case "application/xml":
            $this->app->response->headers->set("Content-Type",'application/xml');
            break; //Break here prevents the next case from firing

        default:
            // default type is application/json
            $this->app->response->headers->set("Content-Type",'application/json');
    }
}

或者

 $this->app->response->withHeader("Content-Type",'application/xml');
