我将我的WordPress网站的MySQL数据库与C＃WebService连接起来。
当我在LocalHost中运行Webservice从我的网站返回值时，但是当我发布webservice并且我使用Android应用程序发送值时返回“null”。
当我更改WebService以返回“Hello World”Android应用程序返回“Hello World”时。
我该如何解决这个问题？
WebService的：
[WebMethod]
public string GetYazilar(int KategoriID)
{
string YaziID = "";
MySqlConnection baglanti = new MySqlConnection("Server=xx.xx.xx.xxx; Database=wordpress_e;Uid=xx;Pwd='xxx';");
baglanti.Open();
DataSet ds = null;
//MySqlCommand cmd = new MySqlCommand("SELECT * FROM 1sbwt_term_taxonomy INNER JOIN 1sbwt_term_relationships ON 1sbwt_term_relationships.term_taxonomy_id = 1sbwt_term_taxonomy.term_id INNER JOIN 1sbwt_posts ON 1sbwt_term_relationships.object_id = 1sbwt_posts.ID WHERE 1sbwt_term_taxonomy.term_id = " + KategoriID + " ");
MySqlDataAdapter da = new MySqlDataAdapter("SELECT * FROM 3tkqs_term_taxonomy INNER JOIN 3tkqs_term_relationships ON 3tkqs_term_relationships.term_taxonomy_id = 3tkqs_term_taxonomy.term_id INNER JOIN 3tkqs_posts ON 3tkqs_term_relationships.object_id = 3tkqs_posts.ID WHERE 3tkqs_term_taxonomy.term_id = " + KategoriID + "", baglanti);
ds = new DataSet();
da.Fill(ds);
if (ds != null && ds.Tables != null && ds.Tables.Count > 0 &&
ds.Tables[0] != null && ds.Tables[0].Rows.Count > 0)
{
DataTable tbl = ds.Tables[0];
for (int i = 0; i < tbl.Rows.Count; i++)
{
YaziID = tbl.Rows[i]["ID"].ToString();
}
}
return YaziID;
}
Android应用程序：
