如何在HttpPost中使用参数

json

我正在通过此方法使用RESTfull Web服务:

@POST
@Consumes({"application/json"})
@Path("create/")
public void create(String str1, String str2){
System.out.println("value 1 = " + str1);
System.out.println("value 2 = " + str2);
}

在我的Android应用中,我想调用此方法。如何使用org.apache.http.client.methods.HttpPost给参数赋予正确的值;

我注意到我可以使用批注@HeaderParam并将标题添加到HttpPost对象。这是正确的方法吗?这样做:

httpPost.setHeader("Accept", "application/json");
httpPost.setHeader("str1", "a value");
httpPost.setHeader("str2", "another value");

在httpPost上使用setEntity方法将不起作用。它仅使用json字符串设置参数str1。像这样使用时:

JSONObject json = new JSONObject();
json.put("str1", "a value");
json.put("str2", "another value");
HttpEntity e = new StringEntity(json.toString());
httpPost.setEntity(e);
//server output: value 1 = {"str1":"a value","str2":"another value"}

要为您设置参数,HttpPostRequest可以使用BasicNameValuePair,例如:

    HttpClient httpclient;
    HttpPost httpPost;
    ArrayList<NameValuePair> postParameters;
    httpclient = new DefaultHttpClient();
    httpPost = new HttpPost("your login link");


    postParameters = new ArrayList<NameValuePair>();
    postParameters.add(new BasicNameValuePair("param1", "param1_value"));
    postParameters.add(new BasicNameValuePair("param2", "param2_value"));

    httpPost.setEntity(new UrlEncodedFormEntity(postParameters, "UTF-8"));

    HttpResponse response = httpclient.execute(httpPost);
