我用java方法编写，负责发送
POST
like
ajax

public String getWebInfo() {

    DefaultHttpClient httpclient = null;
    String out = null;

    try {
        System.out.println("send started");
        httpclient = new DefaultHttpClient();

        Credentials cred = new UsernamePasswordCredentials("user", "password");


         httpclient.getCredentialsProvider().setCredentials(
                    new AuthScope(AuthScope.ANY_HOST, AuthScope.ANY_PORT, AuthScope.ANY_REALM),
                    cred);

         HttpPost httpost = new HttpPost("https://page/php/data.ajax.php");

        List <NameValuePair> nvps = new ArrayList <NameValuePair>();
        nvps.add(new BasicNameValuePair("action", "1"));
        nvps.add(new BasicNameValuePair("name", "2"));

        UrlEncodedFormEntity entityU = new UrlEncodedFormEntity(nvps);
        entityU.setContentEncoding(HTTP.UTF_8);
        //entityU.setContentType("application/json");
        httpost.setEntity(entityU);



        System.out.println("send about to do post");
        HttpResponse response = httpclient.execute(httpost);
        System.out.println("send post done");
        HttpEntity entity = response.getEntity();

        if (entity != null) {
            System.out.println("response.getStatusLine: " + response.getStatusLine());
            InputStream is = entity.getContent();
            InputStreamReader isr = new InputStreamReader(is);
            BufferedReader br = new BufferedReader(isr);
            String line = null;
            while ( (line = br.readLine()) != null) {
                System.out.println("Response: " +  line);
                out = line;
            }
            is.close();

        } else {
            System.out.println("Response: response is null");
        }

    } catch (Exception e) {
        e.getStackTrace();
    }

    if (httpclient != null) {
        httpclient.getConnectionManager().shutdown();
    }

    return out;     
}
服务器端

从我在
msqLogFile（“page/post”，Array（'post'=>urldecode（内爆（“，”，$\u post）））上的日志

我只获取不带密钥的数据：


"2013-05-02 04:21:09","1,2"


它应该是json数据：

从
tail-f/etc/httpd/logs/ssl\u请求\u log


 82.80.25.130 TLSv1 AES128-SHA "POST /page/php/data.ajax.php HTTP/1.1" 484
 82.80.25.130 TLSv1 AES128-SHA "POST /page/php/data.ajax.php HTTP/1.1" 3


当我取消对entityU.setContentType（“应用程序/json”）的注释时，我没有得到任何数据

从javascript开始，一切正常：


var json = JSON.stringify({action: 1,name: 2});
        $.ajax({
            type: "POST",
            url: "/page/php/data.ajax.php",
            dataType:"json",
            data:{data:json},
            success:function(data){


我得到的回应是：


"2013-05-02 04:21:09","{"action":1,"name":2}"



public String getWebInfo() {

DefaultHttpClient httpclient = null;
String out = null;

try {
    System.out.println("send started");
    httpclient = new DefaultHttpClient();

    Credentials cred = new UsernamePasswordCredentials("user", "password");


     httpclient.getCredentialsProvider().setCredentials(
                new AuthScope(AuthScope.ANY_HOST, AuthScope.ANY_PORT, AuthScope.ANY_REALM),
                cred);

     HttpPost httpost = new HttpPost("https://page/php/data.ajax.php");

     JSONObject jsonObj = new JSONObject();
     jsonObj.put("action", 1);
     jsonObj.put("name", 2);


    List <NameValuePair> nvps = new ArrayList <NameValuePair>();
    nvps.add(new BasicNameValuePair("data", jsonObj.toString()));


    UrlEncodedFormEntity entityU = new UrlEncodedFormEntity(nvps);
    entityU.setContentEncoding(HTTP.UTF_8);
    //entityU.setContentType("application/json");
    httpost.setEntity(entityU);



    System.out.println("send about to do post");
    HttpResponse response = httpclient.execute(httpost);
    System.out.println("send post done");
    HttpEntity entity = response.getEntity();

    if (entity != null) {
        System.out.println("response.getStatusLine: " + response.getStatusLine());
        InputStream is = entity.getContent();
        InputStreamReader isr = new InputStreamReader(is);
        BufferedReader br = new BufferedReader(isr);
        String line = null;
        while ( (line = br.readLine()) != null) {
            System.out.println("Response: " +  line);
            out = line;
        }
        is.close();

    } else {
        System.out.println("Response: response is null");
    }

} catch (Exception e) {
    e.getStackTrace();
}

if (httpclient != null) {
    httpclient.getConnectionManager().shutdown();
}

return out;     
}


我的问题在哪里


谢谢，
我找到了解决办法，但假设有人会找到更好的答案：


"2013-05-02 04:21:09","{"action":1,"name":2}"



public String getWebInfo() {

DefaultHttpClient httpclient = null;
String out = null;

try {
    System.out.println("send started");
    httpclient = new DefaultHttpClient();

    Credentials cred = new UsernamePasswordCredentials("user", "password");


     httpclient.getCredentialsProvider().setCredentials(
                new AuthScope(AuthScope.ANY_HOST, AuthScope.ANY_PORT, AuthScope.ANY_REALM),
                cred);

     HttpPost httpost = new HttpPost("https://page/php/data.ajax.php");

     JSONObject jsonObj = new JSONObject();
     jsonObj.put("action", 1);
     jsonObj.put("name", 2);


    List <NameValuePair> nvps = new ArrayList <NameValuePair>();
    nvps.add(new BasicNameValuePair("data", jsonObj.toString()));


    UrlEncodedFormEntity entityU = new UrlEncodedFormEntity(nvps);
    entityU.setContentEncoding(HTTP.UTF_8);
    //entityU.setContentType("application/json");
    httpost.setEntity(entityU);



    System.out.println("send about to do post");
    HttpResponse response = httpclient.execute(httpost);
    System.out.println("send post done");
    HttpEntity entity = response.getEntity();

    if (entity != null) {
        System.out.println("response.getStatusLine: " + response.getStatusLine());
        InputStream is = entity.getContent();
        InputStreamReader isr = new InputStreamReader(is);
        BufferedReader br = new BufferedReader(isr);
        String line = null;
        while ( (line = br.readLine()) != null) {
            System.out.println("Response: " +  line);
            out = line;
        }
        is.close();

    } else {
        System.out.println("Response: response is null");
    }

} catch (Exception e) {
    e.getStackTrace();
}

if (httpclient != null) {
    httpclient.getConnectionManager().shutdown();
}

return out;     
}

很好，你找到了它。我读了这篇文章，看看你们是如何测试的，并提出了一个建议

如果您正在使用大量http，那么您将在dev中获得良好的结果，因为您能够卷曲所有表达式，以查看您的跨网络工作流是否正常。如果需要，您的单元测试可以包括Bash脚本，这些脚本只发送一大串http流量

在java中，您需要找到一种切换http日志的方法，以便您的普通记录器可以编写如下所示的头/线语句——请参阅accept ans--

您将清楚地看到服务器的所有标题和FRM，以及连接到/FRM服务器的线路上的所有主体信息，这些信息在您的正常记录器中以“方向”显示

弄清楚怎么做很难，但当你弄明白的时候，我觉得值得一读


您是否使用Wireshark来查看实际发生的情况？我怀疑您的nvp对象没有被正确序列化。我试图只发送json数据，但通过这种方式POST是空的
