前提:

1、Restful风格的WS服务端:Web Service笔记(五):CXF开发RESTful风格的Web Service

2、访问客户端的技术太多了,这边总结下本人使用过的,主要是四种:WebClient 、HttpURLConnection、HttpClient 和RestTemplate

3、服务端代码实现为 Web Service笔记(五):CXF开发RESTful风格的Web Service 中的sendXml()方法,访问地址与客户端传输的xml文件分别为:
[java] view plain copy

// 发送的报文  
String mRequestXml = "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?><USER><AGE>27</AGE><NAME>SAM-SHO</NAME><PhoneList><UserPhone><num>13612345678</num><type>移动</type></UserPhone><UserPhone><num>13798765432</num><type>联通</type></UserPhone></PhoneList><UserAddress><homeAddress>苏州高新区</homeAddress><workAddress>苏州园区</workAddress></UserAddress></USER>";  

// 服务端地址  
String mUrl = "http://localhost:8080/Java_WS_Server/rest/surpolicy/sendXml";

一、WebClient

(一)WebClient 客户端

1、WebClient 是CXF自带的客户端实现,比较简单实用。

2、客户端代码如下:

[java] view plain copy

/** 
 * WebClient 的客户端访问 
 */  
private void WebClientVisit() {  
    // 手动创建webClient对象,注意这里的地址是发布的那个/rest地址  
    // String url = "http://localhost:8080/Java_WS_Server/rest/";  
    // WebClient client = WebClient.create(url);  

    // 从Spring Ioc容器中拿webClient对象,或者直接用注入  
    ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext-client.xml");  
    WebClient client = ctx.getBean("webClient", WebClient.class);  

    // 设置超时  
    ClientConfiguration config = WebClient.getConfig(client);  
    config.getHttpConduit().getClient().setReceiveTimeout(90000);  

    String tResponseMsg = client.path("surpolicy/sendXml").accept(MediaType.APPLICATION_XML).post(mRequestXml, String.class);  
    System.out.println("返回的信息: \r\n" + tResponseMsg);  

}

(二)WebClient 详解

1、WebClient.create(String url):访问地址。

2、path(String url,Object parames):地址 和 参数 。

3、accept(String… types):接收的类型。

4、get/post(Object body, Class responseClass):发送的内容 和 返回的类型。

5、设置超时(固定用法):

[java] view plain copy

ClientConfiguration config = WebClient.getConfig(client);  
config.getHttpConduit().getClient().setReceiveTimeout(90000);//设置超时

(三)WebClient 工具类封装

    }  

}

二、HttpURLConnection

(一)HttpURLConnection客户端

1、java自带的api,位于net包下,使用较为繁琐,基本功能齐全。

2、客户端代码如下:

[java] view plain copy

/** 
 * HttpURLConnection 的客户端访问 
 */  
private void connectionClientVisit() {  

    // 定义输入输出参数  
    String returnXml = ""; // 核心返回结果报文字符串  
    String strMessage = "";  

    // 发送报文  
    BufferedReader reader = null;  
    StringBuffer buffer = new StringBuffer();  

    // System.setProperty("http.proxyHost","10.7.9.8");//设置代理  
    // System.setProperty("http.proxyPort","54367");  

    try {  

        URL sendUrl = new URL(mUrl);  
        HttpURLConnection conn = (HttpURLConnection) sendUrl.openConnection();  

        conn.setRequestMethod("POST");// 设定请求方式  
        conn.setConnectTimeout(5000); // 设置连接超时为5秒  
        conn.setDoOutput(true);// 设置是否向connection输出,因为这个是post请求,参数要放在  
        // http正文内,因此需要设为true  
        conn.setDoInput(true);// Read from the connection. Default is true.  
        conn.setAllowUserInteraction(true);  
        conn.setUseCaches(false); // Post 请求不能使用缓存  
        conn.setRequestProperty("Content-Language", "GBK");  
        conn.setRequestProperty("Content-Type", "text/xml");// 设置header信息,这个必不可少  

        // 连接,从sendUrl.openConnection()至此的配置必须要在 connect 之前完成,  
        // 要注意的是 conn.getOutputStream 会隐含的进行 connect。  
        // conn.connect();//连接,可以省略  
        OutputStream stream = conn.getOutputStream();  

        stream.write(mRequestXml.getBytes());  
        stream.flush();  
        stream.close();  
        // 获取返回的数据  
        // 无论是post还是get,http请求实际上直到HttpURLConnection.getInputStream()这个函数里面才正式发送出去。  
        InputStream inputStream = conn.getInputStream();  
        reader = new BufferedReader(new InputStreamReader(inputStream, "UTF-8"));  
        while ((strMessage = reader.readLine()) != null) {  
            buffer.append(strMessage);  
        }  
        returnXml = buffer.toString();  

        System.out.println("HttpURLConnection 的客户端接收返回值: \r\n" + returnXml);  

        reader.close();  
        conn.disconnect();  
    } catch (MalformedURLException e) {  
        e.printStackTrace();  
    } catch (IOException e) {  
        e.printStackTrace();  
    }  
}

(二)HttpURLConnection 详解:注意发送的时机

1、Get方式的访问:

[java] view plain copy

/** 
 * Get方式 
 * @throws IOException 
 */  
public static void readContentFromGet() throws IOException {  
    // 拼凑get请求的URL字串,使用URLEncoder.encode对特殊和不可见字符进行编码  
    String getURL = GET_URL + "?username=" + URLEncoder.encode("你好", "utf-8");  
    URL getUrl = new URL(getURL);  
    // 根据拼凑的URL,打开连接,URL.openConnection函数会根据URL的类型,  
    // 返回不同的URLConnection子类的对象,这里URL是一个http,因此实际返回的是HttpURLConnection  
    HttpURLConnection connection = (HttpURLConnection) getUrl.openConnection();  
    // 进行连接,但是实际上get request要在下一句的connection.getInputStream()函数中才会真正发到服务器  
    connection.connect();  
    // 取得输入流,并使用Reader读取  
    BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));  
    System.out.println("=============================");  
    System.out.println("Contents of get request");  
    System.out.println("=============================");  
    String lines;  
    while ((lines = reader.readLine()) != null) {  
        System.out.println(lines);  
    }  
    reader.close();  
    // 断开连接

2、Post方式的访问:

[java] view plain copy

/**

 * @throws IOException 
 */  
public static void readContentFromPost() throws IOException {  
    // Post请求的url,与get不同的是不需要带参数  
    URL postUrl = new URL(POST_URL);  
    // 打开连接  
    HttpURLConnection connection = (HttpURLConnection) postUrl.openConnection();  
    // Output to the connection. Default is  
    // false, set to true because post  
    // method must write something to the  
    // connection  
    // 设置是否向connection输出,因为这个是post请求,参数要放在  
    // http正文内,因此需要设为true  
    connection.setDoOutput(true);  
    // Read from the connection. Default is true.  
    connection.setDoInput(true);  
    // Set the post method. Default is GET  
    connection.setRequestMethod("POST");  
    // Post cannot use caches  
    // Post 请求不能使用缓存  
    connection.setUseCaches(false);  
    // This method takes effects to  
    // every instances of this class.  
    // URLConnection.setFollowRedirects是static函数,作用于所有的URLConnection对象。  
    // connection.setFollowRedirects(true);  

    // This methods only  
    // takes effacts to this  
    // instance.  
    // URLConnection.setInstanceFollowRedirects是成员函数,仅作用于当前函数  
    connection.setInstanceFollowRedirects(true);  
    // Set the content type to urlencoded,  
    // because we will write  
    // some URL-encoded content to the  
    // connection. Settings above must be set before connect!  
    // 配置本次连接的Content-type,配置为application/x-www-form-urlencoded的  
    // 意思是正文是urlencoded编码过的form参数,下面我们可以看到我们对正文内容使用URLEncoder.encode  
    // 进行编码  
    connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");  
    // 连接,从postUrl.openConnection()至此的配置必须要在connect之前完成,  
    // 要注意的是connection.getOutputStream会隐含的进行connect。  
    connection.connect();  
    DataOutputStream out = new DataOutputStream(connection.getOutputStream());  
    // The URL-encoded contend  
    // 正文,正文内容其实跟get的URL中'?'后的参数字符串一致  
    String content = "firstname=" + URLEncoder.encode("一个大肥人", "utf-8");  
    // DataOutputStream.writeBytes将字符串中的16位的unicode字符以8位的字符形式写道流里面  
    out.writeBytes(content);  

    out.flush();  
    out.close(); // flush and close  
    BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));  
    String line;  
    System.out.println("=============================");

    while ((line = reader.readLine()) != null) {  
        System.out.println(line);  
    }  
    System.out.println("=============================");  
    System.out.println("Contents of post request ends");  
    System.out.println("=============================");  
    reader.close();  
    connection.disconnect();  
}

3、利用setChunkedStreamingMode 改变发送的时机

    /**//* 
         * 与readContentFromPost()最大的不同,设置了块大小为5字节 
         */  
    connection.setChunkedStreamingMode(5);  
    connection.connect();  
    /**//* 
         * 注意,下面的getOutputStream函数工作方式于在readContentFromPost()里面的不同 
         * 在readContentFromPost()里面该函数仍在准备http request,没有向服务器发送任何数据 
         * 而在这里由于设置了ChunkedStreamingMode,getOutputStream函数会根据connect之前的配置 
         * 生成http request头,先发送到服务器。 
         */  
    DataOutputStream out = new DataOutputStream(connection.getOutputStream());  
    String content = "firstname="  
            + URLEncoder.encode("一个大肥人                                                                               " + "                                          "  
                    + "asdfasfdasfasdfaasdfasdfasdfdasfs", "utf-8");  
    out.writeBytes(content);  

    out.flush();  
    out.close(); // 到此时服务器已经收到了完整的http  
                    // request了,而在readContentFromPost()函数里,要等到下一句服务器才能收到http请求。  
    BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));

    System.out.println("=============================");  
    reader.close();
