WCF繫結模式 — basicHttpBinding 之 Java(Netbeans + METRO) 調用
這一篇將要實作 Java Client 如何調用具有使用者帳號密碼認證的 basicHttpBinding 繫結模式的 WCF 服務。原本這一篇是要使用 Eclipse + AXIS2 的﹐不過碰到了一些問題﹐暫時還沒找到解決方法﹐因此仍然是使用 NetBeans IDE + METRO 來介紹。
透過 NetBeans 來調用 basicHttpBinding 模式的 WCF 服務﹐在做法上有一部分和另一篇WCF 繫結模式–wsHttpBinding 之 Java (NetBeans + METRO) 調用的做法有些不同﹐比較起來是簡單多了。在一開始建立專案到轉換檔案格式﹐這都和上一篇wsHttpBinding相同。
建立專案
在NetBeans中新增一個Java Application的新專案﹐專案名稱為basicHttpClient﹐Main Class為JavaClient。
加入Web Service Client
轉換檔案格式
同樣的必須將NetBeans自動產生的class檔做轉換為UTF-8﹐請參考另一篇的做法。
加入METRO Library
接著需要手動加入 METRO 2.0﹐這裏並不需要用到METRO 2.2.1。步驟上和調用 wsHttpBinding 就有點不同了﹐這裏在程式庫上右鍵選擇Add Library﹐選擇 METRO 2.0 加入就可了。
撰寫 Client 程式
JavaClient.java
1: package basicHttpClient;
2: import com.sun.xml.ws.developer.WSBindingProvider;
3: import org.datacontract.schemas._2004._07.myproducts.Product;
4:
5: public class JavaClient {
6: public static void main(String[] args) {
7: //.keystore位置
8: System.setProperty("javax.net.ssl.trustStore", "D:\\Java\\Certificate\\my.TrustStore");
9: System.setProperty("javax.net.ssl.keyStore", "D:\\Java\\Certificate\\my.TrustStore");
10: //.keystore密碼
11: System.setProperty("javax.net.ssl.trustStorePassword", "123456");
12: System.setProperty("javax.net.ssl.keyStorePassword", "123456");
13:
14: org.tempuri.ProductService service=null;
15: org.tempuri.IProductService port=null;
16: Product product=null;
17: try{
18: service=new org.tempuri.ProductService();
19: port=service.getBasicHttpBindingIProductService();
20:
21: System.out.println(port.saySomething("Hello~~"));
22: System.out.println();
23:
24: product=port.getProduct("P-002");
25: System.out.println("產品編號："+product.getNo().getValue());
26: System.out.println("產品名稱："+product.getName().getValue());
27: System.out.println("產品單價："+product.getPrice());
28: System.out.println("產品數量："+product.getQuantity());
29: }catch(Exception er){
30: er.printStackTrace();
31: }
32: }
33: }
將上述的程式做編譯後執行看看是不是符合我們要的結果。

看起來並不妙﹐這當中出現了一個錯誤訊息﹐No name matching localhost found 。這一段錯誤應該是SSL憑證不被認為是被信任所造成的﹐這可以如下解決。在第 7 行 if(hostname.equals(“localhost”)) 這裏試著用 locahost 或者本機主機名稱試試。
1: public class JavaClient {
2: static {
3: //for localhost testing only
4: javax.net.ssl.HttpsURLConnection.setDefaultHostnameVerifier(
5: new javax.net.ssl.HostnameVerifier() {
6: public boolean verify(String hostname, javax.net.ssl.SSLSession sslSession) {
7: if (hostname.equals("localhost")) {
8: return true;
9: }
10: return false;
11: }
12: });
13: }
14:
15: public static void main(String[] args) {
16: ………
17: }
18: }
再重新執行程式。
輸出的結果﹐看起來是沒有錯﹐但是這裏並沒有做到使用者帳號密碼認證。
修改 WCF 組態設定
打開 WCF 的 web.config 檔案﹐檢視 binding的部分
|
修改前 <basicHttpBinding> <binding name="Products.BasicHttpBindig"> <security mode="Transport"> <transport clientCredentialType="None" /> <message clientCredentialType="UserName" /> </security> </binding> </basicHttpBinding> |
|
修改後 <basicHttpBinding> <binding name="Products.BasicHttpBindig"> <security mode="TransportWithMessageCredential"> <transport clientCredentialType="Certificate" /> <message clientCredentialType="UserName" /> </security> </binding> </basicHttpBinding> |
將設定前後比對﹐主要是security的mode改為TransportWithMessageCredential的混合模式﹐同時也將transport的clientCredentialType改為Certificate。
修改完畢後記得開啟瀏覽器執行wsdl試試是否正常。
編修 Java 程式
WCF組態變更之後重回NetBeans必須將原本參考的WCF服務重新Refresh﹐Refresh會將之前generated程式重新再generated一次﹐所以必須再將所產生的程式再做一次的檔案格式轉換才可以。
這時再執行程式應該會有新的錯誤產生

因此需要再程式中加人實際要驗證的帳號密碼
JavaClient.java
1: package basicHttpClient;
2:
3: import com.sun.xml.ws.developer.WSBindingProvider;
4: import org.datacontract.schemas._2004._07.myproducts.Product;
5:
6: public class JavaClient {
7: static {
8: //for localhost testing only
9: javax.net.ssl.HttpsURLConnection.setDefaultHostnameVerifier(
10: new javax.net.ssl.HostnameVerifier() {
11: public boolean verify(String hostname, javax.net.ssl.SSLSession sslSession) {
12: if (hostname.equals("localhost")) {
13: return true;
14: }
15: return false;
16: }
17: });
18: }
19:
20: public static void main(String[] args) {
21: //.keystore位置
22: System.setProperty("javax.net.ssl.trustStore", "D:\\Java\\Certificate\\my.TrustStore");
23: System.setProperty("javax.net.ssl.keyStore", "D:\\Java\\Certificate\\my.TrustStore");
24: //.keystore密碼
25: System.setProperty("javax.net.ssl.trustStorePassword", "123456");
26: System.setProperty("javax.net.ssl.keyStorePassword", "123456");
27:
28: org.tempuri.ProductService service=null;
29: org.tempuri.IProductService port=null;
30: Product product=null;
31: try{
32: service=new org.tempuri.ProductService();
33: port=service.getBasicHttpBindingIProductService();
34:
35: WSBindingProvider bp = (WSBindingProvider) port;
36: bp.getRequestContext().put(WSBindingProvider.USERNAME_PROPERTY, "testman");
37: bp.getRequestContext().put(WSBindingProvider.PASSWORD_PROPERTY, "a0987");
38:
39: System.out.println(port.saySomething("Hello~~"));
40: System.out.println();
41:
42: product=port.getProduct("P-002");
43: System.out.println("產品編號："+product.getNo().getValue());
44: System.out.println("產品名稱："+product.getName().getValue());
45: System.out.println("產品單價："+product.getPrice());
46: System.out.println("產品數量："+product.getQuantity());
47: }catch(Exception er){
48: er.printStackTrace();
49: }
50: }
51: }
到此執行之後應該就順利成功了。
