我正在尝试将数据从 Android 提交到我的 php 服务器。但是,所有答案似乎都使用了已弃用的 apache http 库。我不想使用它,当我尝试时它没有用。
现在它似乎没有做任何事情。好像连接到了web服务器,但是服务器并没有写入任何数据。如果我只是用浏览器访问这个 url,它会写入一个文件。
php代码为
<?php
// get the "message" variable from the post request
// this is the data coming from the Android app
$message=$_POST["message"];
// specify the file where we will save the contents of the variable message
$filename="androidmessages.html";
// write (append) the data to the file
file_put_contents($filename,$message."<br />",FILE_APPEND);
// load the contents of the file to a variable
$androidmessages=file_get_contents($filename);
// display the contents of the variable (which has the contents of the file)
echo $androidmessages;
?>
然后在 Android Studio 中,我在按下按钮后放置所有代码
loginButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
loadingProgressBar.setVisibility(View.VISIBLE);
loginViewModel.login(usernameEditText.getText().toString(),
passwordEditText.getText().toString());
System.out.println("This is a test");
Thread thread = new Thread(new Runnable() {
@Override
public void run() {
try {
//Your code goes here
URL url = null;
OutputStream out = null;
String urlString = "https://mywebsite.net/php_script.php";
String data = "HelloWorld"; //data to post
try {
url = new URL(urlString);
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setRequestMethod("POST");
urlConnection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
urlConnection.setDoOutput(true);
out = new BufferedOutputStream(urlConnection.getOutputStream());
BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(out, "UTF-8"));
writer.write(data);
writer.flush();
writer.close();
out.close();
urlConnection.connect();
} catch (IOException e) {
System.out.println(e.getMessage());
e.printStackTrace();
}
} catch (Exception e) {
e.printStackTrace();
}
}
});
thread.start();
}
});
}

您的 PHP 代码正在 $_POST 中寻找名为“message”的变量
$message=$_POST["message"];
但是在您的 Android 代码中,您只需将消息数据写入 http 请求正文。

您可以为此使用 JSON 和 Volley!
<?php
$data = json_decode(file_get_contents('php://input'), true);
$filename="androidmessages.html";
file_put_contents($filename,$data["message"]."<br />",FILE_APPEND);
$reponse = array("message" => $androidmessages=file_get_contents($filename));
echo json_encode($reponse);
?>
这在 android (Kotlin) 中:
private fun sendHtmlRequest(view: View){
val jsonobj = JSONObject()
var url = "https://URL.php"
jsonobj.put("message", "test message")
val que = Volley.newRequestQueue(context)
val req = JsonObjectRequest(Request.Method.POST, url, jsonobj,
Response.Listener { response: JSONObject ->
val messageResponse = response.getString("message")
println("response: $messageResponse")
}, Response.ErrorListener{
println("Error")
}
)
que.add(req)
}
