如何使用参数，HttpPost [英] How to use parameters with HttpPost

问题描述

我使用这个梅索德一个REST风格的web服务：

  @POST
@Consumes（{应用/ JSON}）
@Path（创建/）
公共无效创建（字符串STR1，字符串STR2）{
的System.out.println（值1 =+ STR1）;
的System.out.println（值2 =+ STR2）;
}
 

在我的Andr​​oid应用我想调用此方法。我怎么给使用org.apache.http.client.methods.HttpPost的正确值的参数;

我注意到，我可以使用注释@HeaderParam，只是添加页眉到HttpPost对象。这是正确的方法是什么？做这样的：

  httpPost.setHeader（接受，应用/ JSON）;
httpPost.setHeader（STR1，值）;
httpPost.setHeader（STR2，其他值）;
 

使用上httpPost的setEntity梅索德将无法正常工作。它只设置参数STR1用JSON字符串。当使用它像：

 的JSONObject JSON =新的JSONObject（）;
json.put（STR1，值）;
json.put（STR2，其他值）;
HttpEntity E =新StringEntity（json.toString（））;
httpPost.setEntity（E）;
//服务器输出：值1 = {STR1：值，str2的：另一个值}
 

解决方案

要设置PARAMS您HttpPostRequest您可以使用 BasicNameValuePair <​​/ code>，是这样的：

  HttpClient的HttpClient的;
    HttpPost httppost;
    ArrayList的＆LT;的NameValuePair＆GT; postParameters;
    HttpClient的=新DefaultHttpClient（）;
    httppost =新HttpPost（你的登录链接）;


    postParameters =新的ArrayList＆LT;的NameValuePair＆GT;（）;
    postParameters.add（新BasicNameValuePair（参数1，param1_value））;
    postParameters.add（新BasicNameValuePair（param2的，param2_value））;

    httppost.setEntity（新UrlEn codedFormEntity（postParameters））;

    HTT presponse响应= httpclient.execute（httppost）;
 

I am using a RESTfull webservice with this methode:

@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);
}

In my Android app I want to call this method. How do I give the correct values to the parameters using org.apache.http.client.methods.HttpPost;

I have noticed that I can use the annotation @HeaderParam and simply add headers to the HttpPost object. Is this the correct way? Doing it like:

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

Using the setEntity methode on httpPost won't work. It only sets the parameter str1 with the json string. When using it like:

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"} 

解决方案

To set params to your HttpPostRequest you can use BasicNameValuePair, something like this :

    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));

    HttpResponse response = httpclient.execute(httppost);
