Jetty 9 HTTPclient：如何获取请求内容？

Question

我正在使用 Jetty HTTP 客户端发送请求，在下面的测试用例中我想测试负载是否已成功添加：但是我找不到如何从请求 [1]

中获取它

这是我要测试的方法：

public Request createRequest (HttpClient httpClient, String url,HTTP_METHOD http_method, HashMap <String, String> headers,String payload, HashMap <String, String> params){

    Request request;

    request = httpClient.newRequest(url);   
    request.method(getHttpMethod(http_method));

    /* add headers if any */
    if(headers!=null){      
        for (Map.Entry<String, String> entry : headers.entrySet()) {
            request.header(entry.getKey(), entry.getValue());                       
        }               
    }else{/*Nothing to do*/}

    /* add params if any */
    if(params!=null){       
        for (Map.Entry<String, String> entry : params.entrySet()) {
            request.param(entry.getKey(), entry.getValue());                        
        }               
    }else{/*Nothing to do*/}

    /* add content if any*/         
    if(payload!= null){
        request.content(new StringContentProvider(payload,"UTF-8"));                    
    }else{/*Nothing to do*/}
    return request;
}

这是我的测试用例：

@Test
public void testcreateRequestWithPayload()  {   

    TestBackend testBackend = new TestBackend(3);
    String url="http://www.google.com";

    Request request= testBackend.createRequest(testBackend.getHttpClient(), url, HTTP_METHOD.PUT, null, "payload", null);   

    assertEquals("payload".length(),(request.getContent().getLength()));    //not enough
}

我希望能够测试类似的东西：

assertEquals("payload",(request.getContent()));

好吧，您将 StringContentProvider 放在那里，这就是您将使用 getContent() 返回的内容。但实际上你不需要知道，因为 afaik（不是用于码头客户端的那个）你只需要 ContentProvider 接口...

final ContentProvider provider = request.getContent();
final Iterator<ByteBuffer> it = provider.iterator();
while (it.hasNext()) {
    final ByteBuffer next = it.next();
    final byte[] bytes = new byte[next.capacity()];
    next.get( bytes );
    // Should by "payload"
    String content = new String( bytes, Charset.forName( "UTF-8" ) );
}

（从来没有使用过 ByteBuffer，所以也许有一些更好的方法可以做到这一点，但是您应该能够更容易地找到相关文档，因为 ByteBuffer 是标准的 java 而不是码头特定的； -).
