与HTTPGET请求主体的Andr​​oid [英] HttpGet with request body android

问题描述

我尝试使HTTPGET服务器的请求。但在邮件正文应该是一个JSON对象。低于code未工作，因为unit_id和sercret_key没有在身体上的消息服务器发送。我该怎么办呢？

JSONObject的：

  {
unit_id：12345，
SECRET_KEY：sdfadfsa6as987654754
}
 

我的code：

 私人的Htt presponse makeRequest的（INT ID，字符串SecretKey的）抛出异常{
    BasicHttpParams PARAMS =新BasicHttpParams（）;
    params.setParameter（ID，身份证）;    params.setParameter（SECRET_KEYSecretKey的）;    httpget.setHeader（接受，应用/ JSON）;    httpget.setParams（PARAMS）;
    httpget.setHeader（内容类型，应用/ JSON）;    //手柄什么被从页面返回
    返回httpclient.execute（HTTPGET）;
}
 

编辑：在PHP这个请求时这样

 ＆LT; PHP
$ CH = curl_init（）;
curl_setopt（$ CH，CURLOPT_URLhttp://0101.apiary.io/api/reservations/）;
curl_setopt（$ CH，CURLOPT_RETURNTRANSFER，TRUE）;
curl_setopt（$ CH，CURLOPT_HEADER，FALSE）;
curl_setopt（$ CH，CURLOPT_POSTFIELDS，{\\ n \\unit_id \\：12345，\\ n \\SECRET_KEY \\：\\sdfadfsa6as987654754 \\\\ n}）;
curl_setopt（$ CH，CURLOPT_HTTPHEADER，阵列（内容类型：应用程序/ JSON））;
$响应= curl_exec（$ CH）;
curl_close（$ CH）;后续代码var_dump（$响应）;
 

解决方案

基本上，你不能用 HTTP / GET 请求发送在人体内（JSON或任何东西）行数据。 的协议根本不允许你这样做。显然，你将不得不使用发表做，在Android的了。 ：）

更新

我是不正确的。逸岸协议确实让你把一个实体到请求对象。这个类可以用来代替Apache的 HTTPGET 。

 公共类HttpGetWithEntity扩展HttpEntityEnclosingRequestBase {    公共HttpGetWithEntity（）{
        超（）;
    }    公共HttpGetWithEntity（URI URI）{
        超（）;
        setURI（URI）;
    }    公共HttpGetWithEntity（字符串URI）{
        超（）;
        setURI（URI.create（URI））;
    }    @覆盖
    公共字符串实现getMethod（）{
        返回HttpGet.METHOD_NAME;
    }
}
 

和使用它像如下，

  HttpClient的客户端=新DefaultHttpClient（）;
HttpGetWithEntity myGet =新HttpGetWithEntity（URL这里）;
myGet.setEntity（新StringEntity（这是身体，UTF8））;
HTT presponse响应= client.execute（myGet）;
 

为源 HttpGetWithEntity 中找到<一href=\"http://grep$c$c.com/file/repo1.maven.org/maven2/io.searchbox/jest/0.0.4/io/searchbox/client/http/apache/HttpGetWithEntity.java?av=h\"相对=nofollow>这里

I try to make a request on server by HttpGet. But in message body should be a json object. Code below is not working because unit_id and sercret_key are not sent on server in body message. How can I do it?

JSONObject:

{
"unit_id": 12345,
"secret_key": "sdfadfsa6as987654754"
}

My code:

private HttpResponse makeRequest(int id, String secretKey) throws Exception {
    BasicHttpParams params = new BasicHttpParams();
    params.setParameter("id", id);

    params.setParameter("secret_key", secretKey);

    httpget.setHeader("Accept", "application/json");

    httpget.setParams(params);
    httpget.setHeader("Content-type", "application/json");

    // Handles what is returned from the page
    return httpclient.execute(httpget);
}

Edit: in php this request is made like this

<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://0101.apiary.io/api/reservations/");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_HEADER, FALSE);
curl_setopt($ch, CURLOPT_POSTFIELDS, "{\n    \"unit_id\": 12345,\n    \"secret_key\":     \"sdfadfsa6as987654754\"\n}");
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/json"));
$response = curl_exec($ch);
curl_close($ch);

var_dump($response);

解决方案

Basically, you cannot send row data in the body (JSON or anything) with an HTTP/GET request. The protocol simply does not allow you to do that. Obviously, you will have to use POST to do that in Android too. :)

UPDATE

I was incorrect. Infact the protocol does allow you to put an entity into the request object. This class can be used instead of Apache HttpGet.

public class HttpGetWithEntity extends HttpEntityEnclosingRequestBase {

    public HttpGetWithEntity() {
        super();
    }

    public HttpGetWithEntity(URI uri) {
        super();
        setURI(uri);
    }

    public HttpGetWithEntity(String uri) {
        super();
        setURI(URI.create(uri));
    }

    @Override
    public String getMethod() {
        return HttpGet.METHOD_NAME;
    }
}

And use it like as follows,

HttpClient client = new DefaultHttpClient();
HttpGetWithEntity myGet = new HttpGetWithEntity("Url here");
myGet.setEntity(new StringEntity("This is the body", "UTF8"));
HttpResponse response = client.execute(myGet);
