Question

我需要添加非标准请求标头，其格式如下：（X-MMP-Params：fs = 640x0）。我在这里使用的是HTTPClient代码：

HttpClient client = new DefaultHttpClient();  
String getURL = "http://example.com";
HttpGet get = new HttpGet(getURL);
get.setHeader("X-MMP-Params","fs=640x0"); // I set my request header right here
HttpResponse responseGet = client.execute(get);

这是正确的方法吗？

使用HttpGet获取请求：

public static InputStream getInputStreamFromUrl(String url) {
  InputStream content = null;
  try {
    HttpClient httpclient = new DefaultHttpClient();
    HttpResponse response = httpclient.execute(new HttpGet(url));
    content = response.getEntity().getContent();
  } catch (Exception e) {
    Log.("[GET REQUEST]", "Network exception", e);
  }
    return content;
}

发出POST请求 HttpPost：

public void postData() {
    // Create a new HttpClient and Post Header
    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost("http://www.yoursite.com/script.php");

    try {
        // Add your data
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
        nameValuePairs.add(new BasicNameValuePair("id", "12345"));
        nameValuePairs.add(new BasicNameValuePair("stringdata", "AndDev is Cool!"));
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

        // Execute HTTP Post Request
        HttpResponse response = httpclient.execute(httppost);

    } catch (ClientProtocolException e) {
        // TODO Auto-generated catch block
    } catch (IOException e) {
        // TODO Auto-generated catch block
    }
}

我个人重新尝试使用Retrofit 以下列方式

public interface YourUsersApi {

   //You can use rx.java for sophisticated composition of requests 
   @GET("/users/{user}")
   public Observable<SomeUserModel> fetchUser(@Path("user") String user);

   //or you can just get your model if you use json api
   @GET("/users/{user}")
   public SomeUserModel fetchUser(@Path("user") String user);

   //or if there are some special cases you can process your response manually 
   @GET("/users/{user}")
   public Response fetchUser(@Path("user") String user);

}

如何向HttpClient请求添加请求标头？
