ZF2 / Api呼叫请求抛出请求必须分块或具有内容长度

Question

我尝试处理外部API和POST json数据。

public function execute()
    {
        // ...
        try
        {
            $request = new Request();
            $request->setUri($this->getUrl());
            $request->setMethod('POST');
            $request->setHeaders($request->getHeaders()->addHeaders($this->getHeaders()));

            $client = new Client();
            $client->setOptions(['sslverifypeer' => false]);
            $client->setRawBody($this->getContent()); // content is JSON encoded

            $response = $client->dispatch($request);
        }
        catch (\Exception $e)
        {
            throw new Exception(Exception::UNEXPECTED_ERROR, $e->getMessage());
        }

        var_dump($response); exit;

        // ...
    }

protected function getHeaders()
    {
        return [
            'Content-Type'  => 'application/json; charset=utf-8',
            //'Content-Length' => strlen($this->getContent()),
            'Accept'        => 'application/json',
            'Authorization' => Client::AUTH_BASIC . ' ' . base64_encode($this->username . ':' . $this->secret)
        ];
    }

如果我没有发送Content-length标头，则会抛出此错误The request must be chunked or have a content length

如果我发送，应用程序会抛出read timeout错误

所有想法都将受到赞赏
