我想用齐射来发布数据。
这是我的PHP脚本：
<?php header('Content-Type: application/json; charset=utf-8');
/*
* Following code will update a product information
* A product is identified by product id (pid)
*/
// array for JSON response
$response = array();
// check for required fields
if (isset($_POST['quotes_id']) && isset($_POST['quote']) && isset($_POST['uid']) && isset($_POST['imageName']) && isset($_POST['nameOfCreator']) ) {
$quotes_id = $_POST['quotes_id'];
$quote = $_POST['quote'];
$uid = $_POST['uid'];
$imageName = $_POST['imageName'];
$nameOfCreator = $_POST['nameOfCreator'];
// include db connect class
require_once __DIR__ . '/db_connect.php';
// connecting to db
$db = new DB_CONNECT();
// mysql update row with matched pid
$result = mysql_query("INSERT INTO quotes SET quote = '$quote', uid = '$uid', imageName = '$imageName', nameOfCreator = '$nameOfCreator'");
// check if row inserted or not
if ($result) {
// successfully updated
$response["success"] = 1;
$response["message"] = "Product successfully updated.";
// echoing JSON response
echo json_encode($response);
} else {
}
} else {
// required field is missing
$response["success"] = 0;
$response["message"] = "Required field(s) is missing";
// echoing JSON response
echo json_encode($response);
}
?>
以下是我在单击按钮时调用的方法：
private void setData() {
Map<String, String> jsonParams = new HashMap<String, String>();
jsonParams.put(StaticVariables.QUOTES_ID, null);
jsonParams.put(StaticVariables.QUOTE, "ööö");
jsonParams.put(StaticVariables.UID, "112");
jsonParams.put(StaticVariables.IMAGE_NAME, "112v1.jpg");
jsonParams.put("nameOfCreator", "aa");
JsonObjectRequest myRequest = new JsonObjectRequest(
Request.Method.POST,
StaticVariables.url_insert_quote,
new JSONObject(jsonParams),
new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
// verificationSuccess(response);
Log.e("JA", "nice");
}
},
new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
// verificationFailed(error);
}
}) {
@Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<String, String>();
headers.put("Content-Type", "application/json; charset=utf-8");
headers.put("User-agent", "My useragent");
return headers;
}
};
AppController.getInstance().addToRequestQueue(myRequest, "tag");
}
但是，没有行会插入到我的mysql数据库中。此外，我还设置了INTERNET PERMISSION以及进行Internet连接所需的所有内容。
试试下面的代码，它对我在android应用中有效，并且您必须使用另一个url来发布：
private void registerUser(){
final String username = editTextUsername.getText().toString().trim();
final String password = editTextPassword.getText().toString().trim();
StringRequest stringRequest = new StringRequest(Request.Method.POST, REGISTER_URL,
new Response.Listener<String>() {
@Override
public void onResponse(String response) {
//do stuffs with response of post
}
},
new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
//do stuffs with response erroe
}
}){
@Override
protected Map<String,String> getParams(){
Map<String,String> params = new HashMap<String, String>();
params.put(KEY_PASSWORD,password);
params.put(KEY_EMAIL, email);
return params;
}
};
RequestQueue requestQueue = Volley.newRequestQueue(this);
requestQueue.add(stringRequest);
}
我不确定您是否使用php代码，但在android部分以上有效，
您可能知道您必须
添加互联网权限：
<uses-permission android:name="android.permission.INTERNET" />
将volley添加到build.gradle：
compile 'com.mcxiaoke.volley:library:1.0.19'
谢谢
