[转]android通过webservice验证用户
本文转自：http://danielzzu.blog.163.com/blog/static/118515304201011103562841/
在企业应用中，手机与企业数据的交互必不可少，在这里我们通过实例来描述android怎样调用.net webservice
第一步：vs2008建webservice ,贴出代码:
clsoptuser.cs
public class clsoptuser
{//验证方法
public bool Validate(string u, string p)
{
bool k = false;
SqlConnection userConn = new SqlConnection("连接字符");
userConn.Open();
SqlCommand userComm = new SqlCommand("select *from user", userConn);
SqlDataReader userDr = userComm.ExecuteReader();
string tmpuser, tmppass;
while (userDr.Read())
{
int userindex = userDr.GetOrdinal("user");
int passindex = userDr.GetOrdinal("password");
tmpuser = userDr.GetString(userindex);
tmppass = userDr.GetString(passindex);//用户名和口令正确返回true
if ((tmpuser == u) && (tmppass == p))
{
k = true;
break;
}
}
return k;
}
}
Service.cs
[WebMethod]
public bool ValidateUsername(string username, string pass, string validate)
{
if (validate == "webservice验证码")
{
clsoptuser objoptuser = new clsoptuser();
return objoptuser.Validate(username, pass);
}
else
{
return false;
}
}
以上是服务器端的代码，把上面程序布署到IIS,布署以后可以用IE测试，具体布署我就不说了，网上到处有！
第二步：android客户端
android调用webservice 要用到ksoap2-android-assembly-2.4-jar-with-dependencies.jar一个包，到网上可下载，然后在Eclipce项目中添加处部jar
1、布局文件
main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas./apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"android:background="@drawable/login2"android:gravity="bottom">
<LinearLayout android:id="@+id/LinearLayout02"
android:layout_height="wrap_content"
android:layout_width="fill_parent">
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/labeluser"
android:text="@string/labelname"
android:textStyle="bold"
android:textSize="20sp">
</TextView>
<EditText android:layout_height="wrap_content"
android:id="@+id/EditTextUser"
android:width="150px"
android:layout_width="fill_parent">
</EditText>
</LinearLayout>
<LinearLayout android:id="@+id/LinearLayout03"
android:layout_height="wrap_content"
android:layout_width="fill_parent">
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/labelpass"
android:text="登录密码:"
android:textStyle="bold"
android:textSize="20sp">
</TextView>
<EditText android:layout_height="wrap_content"
android:id="@+id/EditTextPassWord"
android:password="true"
android:layout_width="fill_parent">
</EditText>
</LinearLayout>
<LinearLayout android:id="@+id/LinearLayout04"android:layout_height="wrap_content"android:layout_width="fill_parent"android:gravity="center"><CheckBox android:id="@+id/CheckBox01"android:layout_width="wrap_content"android:layout_height="wrap_content"android:text="记住用户名和密码"android:checked="true"></CheckBox>
</LinearLayout>
<LinearLayout android:id="@+id/LinearLayout01"android:layout_height="wrap_content"android:layout_width="fill_parent"android:layout_gravity="bottom"android:gravity="center"><Button android:id="@+id/BtnLogin"android:text="登 录"android:layout_height="wrap_content"android:layout_width="wrap_content"android:layout_weight="1"></Button><Button android:layout_width="wrap_content"android:layout_height="wrap_content"android:id="@+id/BtnExit"android:text="退 出"android:layout_weight="1"></Button>
</LinearLayout>
</LinearLayout>
想到每次进系统都要输入用户名和密码都恐怖（android的虚拟键盘确实不怎的),所以上面加了个"记住用户名和密码"，方便下次不用输用户名和密码.

for(Iterator it=params.entrySet().iterator();it.hasNext();){
Map.Entry e=(Entry) it.next();
request.addProperty(e.getKey().toString(),e.getValue());
}
}
envelope.bodyOut=request;
//
AndroidHttpTransport androidHttpTrandsport=new AndroidHttpTransport(url);
//HttpTransportSE androidHttpTransport = new HttpTransportSE(url);
SoapObject result=null;
try{
//web service请求
androidHttpTrandsport.call(SOAP_ACTION, envelope);
//得到返回结果
Object temp=envelope.getResult();
response=Boolean.parseBoolean(temp.toString());
}catch(Exception ex){
throw ex;
}
return response;
}
}
}
以上验证程序需要访问网络，别忘了在AndroidManifest.xml加入 <uses-permission android:name="android.permission.INTERNET" />

Calling Web Services in Android using HttpClient
http:///2010/04/27/calling-web-services-in-android-using-httpclient/
Now I am pretty new to Android and Java in general but I feel I’ve come up with a nice simple way to make requests to web services and APIs (and plain html pages if you want). The class uses the org.apache.http library which is included in Android.
This is the code for the class.
public class RestClient {
private ArrayList <NameValuePair> params;
private ArrayList <NameValuePair> headers;
private String url;
private int responseCode;
private String message;
private String response;
public String getResponse() {
return response;
}
public String getErrorMessage() {
return message;
}
public int getResponseCode() {
return responseCode;
}
public RestClient(String url)
{
this.url = url;
params = new ArrayList<NameValuePair>();
headers = new ArrayList<NameValuePair>();
}
public void AddParam(String name, String value)
{
params.add(new BasicNameValuePair(name, value));
}
public void AddHeader(String name, String value)
{
headers.add(new BasicNameValuePair(name, value));
}
public void Execute(RequestMethod method) throws Exception
{
switch(method) {
case GET:
{
//add parameters
String combinedParams = "";
if(!params.isEmpty()){
combinedParams += "?";
for(NameValuePair p : params)
{
String paramString = p.getName() + "=" + URLEncoder.encode(p.getValue(),”UTF-8″);
if(combinedParams.length() > 1)
{
combinedParams += "&" + paramString;
}
else
{
combinedParams += paramString;
}
}
}
HttpGet request = new HttpGet(url + combinedParams);
//add headers
for(NameValuePair h : headers)
{
request.addHeader(h.getName(), h.getValue());
}
executeRequest(request, url);
break;
}
case POST:
{
HttpPost request = new HttpPost(url);
//add headers
for(NameValuePair h : headers)
{
request.addHeader(h.getName(), h.getValue());
}
if(!params.isEmpty()){
request.setEntity(new UrlEncodedFormEntity(params, HTTP.UTF_8));
}
executeRequest(request, url);
break;
}
}
}
private void executeRequest(HttpUriRequest request, String url)
{
HttpClient client = new DefaultHttpClient();
HttpResponse httpResponse;
try {
httpResponse = client.execute(request);
responseCode = httpResponse.getStatusLine().getStatusCode();
message = httpResponse.getStatusLine().getReasonPhrase();
HttpEntity entity = httpResponse.getEntity();
if (entity != null) {
InputStream instream = entity.getContent();
response = convertStreamToString(instream);
// Closing the input strea will trigger connection release
instream.close();
}
utdown();
ce();
{
ace();
amToString(InputStream is) {
BufferedReader reader = new BufferedReader(new InputStreamReader(is));
StringBuilde StringBuilder()
Strin
Here is an example of how I use the class to call the Google Analytics API. I use the AddParam methods to add query string / post values and the AddHeader method to add headers to the request. RequestMethod is a simple enum with GET and POST values.
view sourceprint?
RestClient client = new RestClient(LOGIN_URL);
client.AddParam("accountType", "GOOGLE");
client.AddParam("source", "tboda-widgalytics-0.1");
client.AddParam("Email", _username);
client.AddParam("Passwd", _password);
client.AddParam("service", "analytics");
client.AddHeader("GData-Version", "2");
try {
client.Execute(RequestMethod.POST);
} catch (Exception e) {
e.printStackTrace();
}
String response = client.getResponse();
The class also exposes the Http response code and message which are important when using some Restful APIs. I know could definitely improve/extend on this code and would love to hear from those more experienced in Java and Android than myself. 回复 引用 查看
