PHP的HTTP POST使用Android设备上HttpURLConnection的 [英] PHP HTTP POST on Android device using HttpURLConnection
本文介绍了PHP的HTTP POST使用Android设备上HttpURLConnection的的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
问：
所以，问题是，这并不发布到GoDaddy代管的在线数据库。所以我的问题是为什么，以及如何解决它有它张贴到了吗？
问题：
PHP页面不接收传递给它的名字值对。
编辑：
这是建议修改code使用HttpURLConnection类...
我已经缩小的问题岂不检索fbid。
正如你可以告诉我已经做了很多在这里我的功课......这是我的什么在postthread类被设置的logcat的这里是我的类，它的帖子：

我甚至尝试了Java像这样：
公共无效的run（）{
尝试{
HttpURLConnection的康恩=（HttpURLConnection类）url.openConnection（）;
conn.setReadTimeout（10000）;
conn.setConnectTimeout（15000）; conn.setRequestMethod（POST）; conn.setDoInput（真）;
conn.setDoOutput（真）; 清单＆LT;＆的NameValuePair GT; PARAMS =新的ArrayList＆LT;＆的NameValuePair GT;（）;
对（NVP的NameValuePair：对）{
//你需要连接code参数的唯一值
params.add（新BasicNameValuePair（nvp.getName（），nvp.getValue（）））;
Log.i（PROJECTCARUSO，NVP：+ nvp.getName（）+ - + nvp.getValue（））;
}
OutputStream的OS = conn.getOutputStream（）;
但是BufferedWriter作家=新的BufferedWriter（
新OutputStreamWriter（OS，UTF-8））;
writer.write（getQuery（PARAMS））;
writer.close（）;
os.close（）; conn.connect（）; //建立字符串存储从服务器的响应文本
串响应=; //开始收听流
扫描仪inStream中=新的扫描仪（conn.getInputStream（））; //处理流并将其存储在StringBuilder的

// TODO自动生成catch块
e.printStackTrace（）;
} 赶上（IOException异常五）{
// TODO自动生成catch块
e.printStackTrace（）;
}
解决方案
您必须使用 $ _ POST 而不是 $的_ GET 无处不在。
Question:
So the problem is that this doesn't post to the online database hosted by goDaddy. So my question is why, and how do i fix it to have it post to it?
Issue: The php page is not receiving the name value pairs being passed to it.
Edit:
Modified code on suggestion to use HttpURLConnection... I've narrowed down the problem to it not retrieving the fbid.
As you can tell I’ve done a lot of my homework here... Here's my logcat of what is being set in the postthread class Here's my class that does the post:
07-02 16:41:45.108: I/PROJECTCARUSO(12308): response: {"posts":[null]}
HttpPostThread:
public class HttpPostThread extends Thread {
public static final int FAILURE = 0;
public static final int SUCCESS = 1;
private URL url;
ArrayList<NameValuePair> pairs;
public HttpPostThread(URL sERVICE_URL, ArrayList<NameValuePair> pairs, final Handler handler)
{
Log.i("PROJECTCARUSO", "Posting to URL: " + sERVICE_URL);
this.url =sERVICE_URL;
this.pairs = pairs;
if(pairs==null){
Log.i("PROJECTCARUSO", "URL parms were null");
this.pairs = new ArrayList<NameValuePair>();
}
}
@Override
public void run()
{
try {
HttpURLConnection conn;
String param="";
for (NameValuePair nvp : pairs) {
//you need to encode ONLY the values of the parameters
if (param == "") {
param=nvp.getName() + "=" + URLEncoder.encode(nvp.getValue(),"UTF-8");
} else {
param+= "&" + nvp.getName() + "=" + URLEncoder.encode(nvp.getValue(),"UTF-8");
}
}
Log.i("PROJECTCARUSO", "param: " + param.toString());
// Create connection
conn=(HttpURLConnection)url.openConnection();
//set the output to true, indicating you are outputting(uploading) POST data
conn.setDoOutput(true);
//once you set the output to true, you don't really need to set the request method to post, but I'm doing it anyway
conn.setRequestMethod("POST");
//Android documentation suggested that you set the length of the data you are sending to the server, BUT
// do NOT specify this length in the header by using conn.setRequestProperty("Content-Length", length);
//use this instead.
conn.setFixedLengthStreamingMode(param.getBytes().length);
conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
//send the POST out
PrintWriter out = new PrintWriter(conn.getOutputStream());
out.print(param);
out.close();
//build the string to store the response text from the server
String response= "";
//start listening to the stream
Scanner inStream = new Scanner(conn.getInputStream());
//process the stream and store it in StringBuilder
while(inStream.hasNextLine())
response+=(inStream.nextLine());
Log.i("PROJECTCARUSO","response: " + response);
}
//catch some error
catch(MalformedURLException ex){
Log.i("PROJECTCARUSO", ex.toString());
}
// and some more
catch(IOException ex){
Log.i("PROJECTCARUSO", ex.toString());
}
}
public static boolean isNumeric(String str)
{
try
{
double d = Double.parseDouble(str);
}
catch(NumberFormatException nfe)
{
return false;
}
return true;
}
}
Here's the php:
<?php
//Make connection

exit();

//change db to andriodnfp db
mysqli_select_db($con, 'andriodnfp');

EDIT:
I even tried the java as so:
public void run() {
try {
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setReadTimeout(10000);
conn.setConnectTimeout(15000);
conn.setRequestMethod("POST");
conn.setDoInput(true);
conn.setDoOutput(true);
List<NameValuePair> params = new ArrayList<NameValuePair>();
for (NameValuePair nvp : pairs) {
//you need to encode ONLY the values of the parameters
params.add(new BasicNameValuePair(nvp.getName(), nvp.getValue()));
Log.i("PROJECTCARUSO", "NVP: " + nvp.getName() + " - " + nvp.getValue());
}
OutputStream os = conn.getOutputStream();
BufferedWriter writer = new BufferedWriter(
new OutputStreamWriter(os, "UTF-8"));
writer.write(getQuery(params));
writer.close();
os.close();
conn.connect();
//build the string to store the response text from the server
String response= "";
//start listening to the stream
Scanner inStream = new Scanner(conn.getInputStream());
//process the stream and store it in StringBuilder
while(inStream.hasNextLine())
response+=(inStream.nextLine());
Log.i("PROJECTCARUSO","response: " + response);
} catch (ProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
解决方案
You have to use $_POST instead of $_GET everywhere.
