JSON不工作HttpPost大概在setEntity工作、JSON、setEntity、HttpPost

我用这code发送这对我的PHP文件。 该文件看起来什么是未来是这样的。

  file_put_contents(dump.txt,POST:\ N的print_r($ _ POST,真)\ñ\ñ\ñGET:\ N。的print_r( $ _GET,真));
 

我发送的JSON是这样的:

 公共无效POSTDATA(字符串URL,JSONObject的JSON){
    HttpClient的HttpClient的=新DefaultHttpClient();
    String对象= + json.toString()数据=?;
    的System.out.println(对象:+对象);
    尝试 {
        HttpPost httppost =新HttpPost(url.toString());
        httppost.setHeader(内容型,应用/ JSON);
        的System.out.println(URL:+ url.toString());
        StringEntity SE =新StringEntity(对象);
        的System.out.println(JSON:+ json.toString());

        se.setContentEncoding(新BasicHeader(HTTP.CONTENT_TYPE,应用/ JSON));
        httppost.setEntity(SE);

        HTT presponse响应= httpclient.execute(httppost);
        字符串临时= EntityUtils.toString(response.getEntity());
        的System.out.println(回应:+响应);

        。INT状态code = response.getStatusLine()的getStatus code();
        的System.out.println(状态code+状态code);

        如果(状态code == 200){
            Toast.makeText(LbsGeocodingActivity.thisVerstuurd,Toast.LENGTH_LONG).show();
        }
        否则,如果(状态code!= 200){
            Toast.makeText(这一点,状态code,Toast.LENGTH_LONG).show();
        }
        /* 尝试 {
                串responseBody = EntityUtils.toString(response.getEntity());
        Toast.makeText(这一点,responseBody,Toast.LENGTH_LONG).show();
        }赶上(ParseException的E){
                // TODO自动生成的catch块
                e.printStackTrace();
        }赶上(IOException异常E){
                // TODO自动生成的catch块
                e.printStackTrace();
        } * /
    }
    赶上(ClientProtocolException E){

    }
    赶上(IOException异常E){
    }
}
 

日志文件是这样的:

 九月1日至8日:36:00.278:我/的System.out(1124):对象:数据= {ID:69403,时间戳:08 -01-2013 9时36分00秒,经度: -  122.084095,纬度:37.422005}
9月1日至八日:36:00.298:我/的System.out(1124):JSON:{ID:69403,时间戳:2013年8月1日9时36分00秒,东经: -122.084095,纬度:37.422005}
9月1日至八日:36:01.038:我/的System.out(1124):回应:org.apache.http.message.BasicHtt$p$psponse@412d1b38
9月1日至八日:36:01.038:我/的System.out(1124):状态code 200
 
settings.json的两种配置位置 全局用户设置和工作区设置

我离开了URL出于安全考虑。

但我正在逐渐的dump.txt一个空文件

 邮编:
排列

 得到:

修改

东西是错误的setEntity(或某处身边有),因为当我已经粘贴数据=在URL中我得到这个从PHP文件:?

 得到:

解决方案

我在我的应用程序工作发送JSON和我的 DefaultHttpClient 完美的方式:

 公共静态HttpUriRequest createPostForJSONObject(
        JSONObject的参数,可以字符串URL){
    HttpPost后=新HttpPost(URL);
    post.setEntity(createStringEntity(PARAMS));
    返回岗位;
}

私有静态HttpEntity createStringEntity(JSONObject的PARAMS){
    StringEntity SE = NULL;
    尝试 {
        本身=新StringEntity(params.toString(),UTF-8);
        se.setContentType(应用/ JSON的;字符集= UTF-8);
    }赶上(UnsupportedEncodingException E){
        Log.e(TAG,无法创建StringEntity,E);
        异常= E;
    }
    返回本身;
}
 

为了运行在code此要求所有你需要做的是这样的:

 公共无效POSTDATA(字符串URL,JSONObject的JSON){
    HttpClient的HttpClient的=新DefaultHttpClient();
    尝试 {
          HttpPost后= createPostForJSONObject(JSON,URL);
          HTT presponse响应= httpClient.execute(后);
          //做你的事
    } catch异常{
         //处理异常
    }
}
 

I am using this code to send this to my php file. The file looks what is coming like this.

file_put_contents('dump.txt', "POST: \n" . print_r($_POST, true) . "\n\n\n GET: \n" . print_r($_GET, true));

I am sending the json like this:

public void postData(String url,JSONObject json) {
    HttpClient httpclient = new DefaultHttpClient();
    String object = "?data=" +json.toString();
    System.out.println("object:" + object);
    try {
        HttpPost httppost = new HttpPost(url.toString());
        httppost.setHeader("Content-type", "application/json");
        System.out.println("url:" + url.toString());
        StringEntity se = new StringEntity(object); 
        System.out.println("json:" + json.toString());

        se.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
        httppost.setEntity(se); 

        HttpResponse response = httpclient.execute(httppost);
        String temp = EntityUtils.toString(response.getEntity());
        System.out.println("response:" + response);

        int statusCode = response.getStatusLine().getStatusCode();
        System.out.println("Statuscode " + statusCode);

        if(statusCode==200) {
            Toast.makeText(LbsGeocodingActivity.this, "Verstuurd",  Toast.LENGTH_LONG).show();
        }
        else if(statusCode!=200) {
            Toast.makeText(this, statusCode, Toast.LENGTH_LONG).show();
        }
        /* try {
                String responseBody = EntityUtils.toString(response.getEntity());
        Toast.makeText(this, responseBody, Toast.LENGTH_LONG).show();
        } catch (ParseException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
        } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
        }*/
    } 
    catch (ClientProtocolException e) {

    } 
    catch (IOException e) {
    }
}

The log files are this:

01-08 09:36:00.278: I/System.out(1124): object:?data={"id":"69403","timestamp":"08-01-2013 09:36:00","longitude":"-122.084095","latitude":"37.422005"}
01-08 09:36:00.298: I/System.out(1124): json:{"id":"69403","timestamp":"08-01-2013 09:36:00","longitude":"-122.084095","latitude":"37.422005"}
01-08 09:36:01.038: I/System.out(1124): response:org.apache.http.message.BasicHttpResponse@412d1b38
01-08 09:36:01.038: I/System.out(1124): Statuscode 200

i left out the url for security reasons..

But i am getting an empty file in dump.txt

POST: 
Array
(
)



 GET: 
Array
(
)

EDIT

Something is wrong with the setEntity(or somewhere around there), because when i already paste ?data= in the url i get this from the PHP file:

POST: 
Array
(
)



 GET: 
Array
(
    [data] => 
)

解决方案

the way I send JSON with my DefaultHttpClient in my app work perfectly:

public static HttpUriRequest createPostForJSONObject(
        JSONObject params, String url) {
    HttpPost post = new HttpPost(url);
    post.setEntity(createStringEntity(params));
    return post;
}

private static HttpEntity createStringEntity(JSONObject params) {
    StringEntity se = null;
    try {
        se = new StringEntity(params.toString(), "UTF-8");
        se.setContentType("application/json; charset=UTF-8");
    } catch (UnsupportedEncodingException e) {
        Log.e(TAG, "Failed to create StringEntity", e);
        exception = e;
    }
    return se;
}

in order to run this request in your code all you need to do is this:

public void postData(String url,JSONObject json) {
    HttpClient httpclient = new DefaultHttpClient();
    try {
          HttpPost post = createPostForJSONObject(json, url);
          HttpResponse response = httpClient.execute(post);
          // DO YOUR THING
    } catch Exception {
         // HANDLE EXCEPTION
    }
}
