- 上一節介紹了怎樣實現基本認證(Basic Authentication，以下簡稱basic方式)，望文生義，也就是最簡單的用戶驗證方式，本節稍微深入一些，介紹用戶名令牌認證(Usernametoken Authentication，以下簡稱usernametoken方式)。
-
- Usernametoken方式與basic方式不同的地方，在于后者會把用戶名和密碼以摘要(digest)的形式，置于HTTP信息頭，而前者則把用戶名以明文的形式、密碼以明文或者摘要的形式，嵌入到一段XML文本中，再置于SOAP消息頭當中。
-
- 如果使用soapUI調試客戶端程序的話，會發現以下是basic方式發出的完整的SOAP消息：
- POST https://test2.r-secure.com/Services/ECHO HTTP/0.9
- Content-Type: text/xml;charset=UTF-8
- SOAPAction: ""
- User-Agent: Jakarta Commons-HttpClient/3.1
- Content-Length: 292
- Authorization: Basic VkYtSEstbVNNST0OdlR42EMZaD1BMyE=
- Host: test2.r-secure.com
- Cookie: $Version=0; MSP2LB=test2.test2f02; $Path=/
-
- <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:echo="http://echo.rsecure.com/ECHO">
- <soapenv:Header/>
- <soapenv:Body>
- <echo:echo>
- <echo:EchoMessage>hello</echo:EchoMessage>
- </echo:echo>
- </soapenv:Body>
- </soapenv:Envelope>
-
- 以下是usernametoken方式發出的完整的SOAP消息：
- POST https://test.r-secure.com/4.0/services/SecureEcho HTTP/1.1
- Content-Type: text/xml;charset=UTF-8
- SOAPAction: ""
- User-Agent: Jakarta Commons-HttpClient/3.1
- Host: test.r-secure.com
- Content-Length: xxx
-
- <soapenv:Envelope xmlns:echo="http://echo.ws.rsecure.com" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
- <soapenv:Header>
- <wsse:Security soapenv:mustUnderstand="1" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">
- <wsse:UsernameToken wsu:Id="UsernameToken-32870670" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">
- <wsse:Username>roy</wsse:Username>
- <wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText">liang</wsse:Password>
- <wsse:Nonce>LX4gh+njbEtCNAtkWkXDYA==</wsse:Nonce>
- <wsu:Created>2010-08-11T06:02:25.874Z</wsu:Created>
- </wsse:UsernameToken>
- </wsse:Security>
- <echo:customerId>G06164</echo:customerId>
- </soapenv:Header>
- <soapenv:Body>
- <echo:sendEcho>
- <echo:message>hello</echo:message>
- </echo:sendEcho>
- </soapenv:Body>
- </soapenv:Envelope>
-
- 其中，加粗部分表示兩者的主要區別，紅字部分表示各自必不可少的元素。
-
- 由此可以看出，usernametoken方式的特點，是在SOAP的header中加入一個Security標簽，把usernametoken信息放在這個Security標簽里。至于header里的另外一個customerId標簽，是該應用自身的額外要求。
-
- gSOAP實現basic方式相對簡單，不過實現usernametoken就比較復雜。gSOAP的用戶指南推薦使用其自帶的插件，在samples/wsse目錄下的官方實例也是使用這個插件。但是，我個人認為這種方法比較累贅，自動生成的代碼太多，不易看懂，而且似乎非常依賴于wsdl本身的寫法。比如，samples/wsse目錄下的官方實例含有下列表示SOAP header的結構體，但是，在我實際開發的應用并沒有自動產生，即使強行加上去，編譯執行通過，運行的時候也出現了相當多的錯誤。
 struct SOAP_ENV__Header
 {
 struct _wsse__Security *wsse__Security
 };
-
- 而且，從理論上講，gSOAP不過是一個框架，定義了從SOAP對象到SOAP消息，以及從SOAP消息到SOAP對象的序列化過程，并且提供了一套與之相適應的API，使用gSOAP開發不過是在其框架范圍內調用其API編程。框架的弊端，可想而知，限制了靈活，也限制了方便，更限制了創新。所以，我們可以使用gSOAP編程，但是也許沒有必要全部照搬，至少在這個案例中，就沒有必要照搬。
-
- 我們應有的思路是，既然customerId可以直接寫到SOAP header中，那么與之并列的、含有usernametoken的Security也可以直接寫到SOAP header中，完全不需要依賴于gSOAP的wsse插件。
-
- 與上節一樣，基于保密原則，本節案例采用的wsdl同樣是經過裁剪和替換的，內容如下：

-
- 在gSOAP的wsdl目錄，按以下步驟建立客戶端存根程序：
- -bash-3.2$ mkdir –p secure_echo
- -bash-3.2$ cd secure_echo
- -bash-3.2$ ../wsdl2h –c –o secure_echo.h secure_echo.wsdl
- -bash-3.2$ ../../src/soapcpp2 –C –L –x secure_echo.h
-
- 重點來了，此時需要修改gSOAP為你自動生成的部分文件，加入usernametoken支持，以下是詳細步驟，代碼中加粗部分即修改的內容：
- 1. soapStub.h，搜索SOAP_ENV__Header結構體，本案例中，gSOAP只為我們自動生成了對應customerId的指針，因為需要在SOAP header中增加用戶名和密碼，所以要在這里手動添加這些信息。這樣，修改后的SOAP_ENV__Header變為：
- struct SOAP_ENV__Header
- {
- char *wsse__username; /* mustUnderstand */
- char *wsse__password; /* mustUnderstand */
- char *ns1__customerId; /* mustUnderstand */
- };
- 2. soapC.c，搜索soap_out_SOAP_ENV__Header函數，這是客戶端把SOAP對象轉化為SOAP消息相關的函數，由于gSOAP只是自動生成了customerId屬性的轉化，我們還需要加入Security屬性，按照soapUI測試好的結果，Security含有一個UsernameToken，而UsernameToken又含有用戶名和密碼，因此soap_out函數應當這樣寫：
- SOAP_FMAC3 int SOAP_FMAC4 soap_out_SOAP_ENV__Header(struct soap *soap, const char *tag, int id, const struct SOAP_ENV__Header *a, const char *type)
- {
- if (soap_element_begin_out(soap, tag, soap_embedded_id(soap, id, a, SOAP_TYPE_SOAP_ENV__Header), type))
- return soap->error;
- if (soap_element_begin_out(soap, "wsse:Security", -1, "")
- || soap_element_begin_out(soap, "wsse:UsernameToken", -1, "")
- || soap_out_string(soap, "wsse:Username", -1, &a->wsse__username, "")
- || soap_out_string(soap, "wsse:Password", -1, &a->wsse__password, "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText")
- || soap_element_end_out(soap, "wsse:UsernameToken")
- || soap_element_end_out(soap, "wsse:Security")
- )
- return soap->error;
- soap->mustUnderstand = 1;
- if (soap_out_string(soap, "ns1:customerId", -1, &a->ns1__customerId, ""))
- return soap->error;
- return soap_element_end_out(soap, tag);
- }
- 3. SecureEchoHttpBinding.nsmap，由于上一步用到了wsse這個namespace，而它又沒有出現在nsmap文件中，因此我們需要增加該命名空間的信息，其URL同樣可以從soapUI測試結果中取得：
- SOAP_NMAC struct Namespace namespaces[] =
- {
- {"SOAP-ENV", "http://schemas.xmlsoap.org/soap/envelope/", "http://www.w3.org/*/soap-envelope", NULL},
- {"SOAP-ENC", "http://schemas.xmlsoap.org/soap/encoding/", "http://www.w3.org/*/soap-encoding", NULL},
- {"xsi", "http://www.w3.org/2001/XMLSchema-instance", "http://www.w3.org/*/XMLSchema-instance", NULL},
- {"xsd", "http://www.w3.org/2001/XMLSchema", "http://www.w3.org/*/XMLSchema", NULL},
- {"ns1", "http://echo.ws.rsecure.com", NULL, NULL},
- {"wsse", "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd", NULL, NULL},
- {NULL, NULL, NULL, NULL}
- };
-
- 存根程序修改完成，就可以開始編寫客戶端程序代碼了。這個web service提供了兩個接口，一個是secure_echo，也就是客戶端送任意信息上來，服務端就返回相同的字符串，代碼如下：
-
#include "soapH.h"
#include "SecureEchoHttpBinding.nsmap"
int main(int argc, char **argv) {
 if ( argc != 5 && argc != 6 ) {
printf("Usage: %s username password customer_id message [end_point]\n", argv[0]);
exit(-1);
 }
struct soap soap;
soap_init(&soap);
struct _ns1__sendEcho request;
struct _ns1__sendEchoResponse response;
soap_ssl_init();
if ( soap_ssl_client_context(&soap, SOAP_SSL_NO_AUTHENTICATION, NULL, NULL, NULL, NULL, NULL) ) {
soap_print_fault(&soap, stderr);
exit(-1);
}
struct SOAP_ENV__Header header;
header.wsse__username = argv[1];
header.wsse__password = argv[2];
header.ns1__customerId = argv[3];
soap.header = &header;
//soap_write_SOAP_ENV__Header(&soap, &header);
request.message = argv[4];
char *endpoint = NULL;
if ( argc == 6 )
endpoint = argv[5];
printf("username : %s\n", header.wsse__username);
printf("password : %s\n", header.wsse__password);
printf("customer id : %s\n", header.ns1__customerId);
printf("message : %s\n", request.message);
if ( endpoint )
printf("end point : %s\n", endpoint);
if ( soap_call___ns1__sendEcho(&soap, endpoint, NULL, &request, &response) == SOAP_OK ) {
printf("%s\n", response.out);
}
else {
soap_print_fault(&soap, stderr);
}
soap_destroy(&soap);
soap_end(&soap);
soap_done(&soap);
return 0;
}
-
- 另外一個是顯示版本信息，代碼如下：
-
#include "soapH.h"
#include "SecureEchoHttpBinding.nsmap"
int main(int argc, char **argv) {
if ( argc != 4 && argc != 5 ) {
printf("Usage: %s username password customer_id [end_point]\n", argv[0]);
exit(-1);
}
struct soap soap;
soap_init(&soap);
struct _ns1__showVersionInformation request;
struct _ns1__showVersionInformationResponse response;
soap_ssl_init();
if ( soap_ssl_client_context(&soap, SOAP_SSL_NO_AUTHENTICATION, NULL, NULL, NULL, NULL, NULL) ) {
soap_print_fault(&soap, stderr);
exit(-1);
}
struct SOAP_ENV__Header header;
header.wsse__username = argv[1];
header.wsse__password = argv[2];
header.ns1__customerId = argv[3];
soap.header = &header;
//soap_write_SOAP_ENV__Header(&soap, &header);
char *endpoint = NULL;
if ( argc == 5 )
endpoint = argv[4];
printf("username : %s\n", header.wsse__username);
printf("password : %s\n", header.wsse__password);
printf("customer id : %s\n", header.ns1__customerId);
if ( endpoint )
printf("end point : %s\n", endpoint);
if ( soap_call___ns1__showVersionInformation(&soap, endpoint, NULL, &request, &response) == SOAP_OK ) {
printf("%s\n", response.out);
}
else {
soap_print_fault(&soap, stderr);
}
soap_destroy(&soap);
soap_end(&soap);
soap_done(&soap);
return 0;
}
-
- 兩個客戶端程序都是一樣的結構，僅僅是調用的接口不一樣。與上一節的basic方式的客戶端相比，usernametoken方式的用戶密碼不是保存在soap結構體的userid變量和passwd變量中，而是保存在header指針指向的SOAP_ENV__Header結構體中，這就是剛才我們為什么要修改SOAP_ENV__Header結構體的原因。
-
- 兩個客戶端程序分別保存為secure_echo.c和show_version.c，編譯命令分別是：
- gcc -DWITH_OPENSSL -O2 -o secure_echo secure_echo.c soapC.c soapClient.c ../../stdsoap2.c -I../.. -L../.. -lgsoap -lssl
-
- gcc -DWITH_OPENSSL -O2 -o show_version show_version.c soapC.c soapClient.c ../../stdsoap2.c -I../.. -L../.. -lgsoap –lssl
-
- 由此可見，編譯的源代碼和鏈接的庫文件都與上一節的沒什么區別，沒有使用額外的插件。
-
- 客戶端程序搞掂，然后就是服務端了。
-
- 回到gSOAP的wsdl目錄，按以下步驟建立服務端存根程序：
- -bash-3.2$ mkdir –p secure_echo_server
- -bash-3.2$ cd secure_echo_server
- -bash-3.2$ cp –p ../secure_echo/secure_echo.h .
- -bash-3.2$ ../../src/soapcpp2 –S –L –x secure_echo.h
-
- 與客戶端程序一樣，服務端同樣要進行一些修改，步驟如下：
- 1. soapStub.h，與客戶端的修改是一樣的
- 2. soapC.c，搜索soap_in_SOAP_ENV__Header函數，注意客戶端修改的是soap_out函數，這里是soap_in函數，是服務端把SOAP消息轉化為SOAP對象的函數。由于客戶端送上來的SOAP header消息含有Security屬性，我們需要把它轉為username和password。修改后的代碼如下，加粗部分是修改內容：
- SOAP_FMAC3 struct SOAP_ENV__Header * SOAP_FMAC4 soap_in_SOAP_ENV__Header(struct soap *soap, const char *tag, struct SOAP_ENV__Header *a, const char *type)
- {
- size_t soap_flag_wsse__security = 1;
- size_t soap_flag_ns1__customerId = 1;
- if (soap_element_begin_in(soap, tag, 0, type))
- return NULL;
- a = (struct SOAP_ENV__Header *)soap_id_enter(soap, soap->id, a, SOAP_TYPE_SOAP_ENV__Header, sizeof(struct SOAP_ENV__Header), 0, NULL, NULL, NULL);
- if (!a)
- return NULL;
- soap_default_SOAP_ENV__Header(soap, a);
- if (soap->body && !*soap->href)
- {
- for (;;)
- {
- if ( soap_flag_wsse__security ) {
- if ( soap_element_begin_in(soap, NULL, 0, NULL) )
- return NULL;
- if ( soap_element_begin_in(soap, NULL, 0, NULL) )
- return NULL;
- if ( soap_in_string(soap, "", &a->wsse__username, "")
- && soap_in_string(soap, "", &a->wsse__password, "") ) {
- soap_flag_wsse__security--;
- soap_element_end_in(soap, NULL);
- soap_element_end_in(soap, NULL);
- }
- }
- soap->error = SOAP_TAG_MISMATCH;
- if (soap_flag_ns1__customerId && (soap->error == SOAP_TAG_MISMATCH || soap->error == SOAP_NO_TAG))
- if (soap_in_string(soap, "ns1:customerId", &a->ns1__customerId, "xsd:string"))
- { soap_flag_ns1__customerId--;
- continue;
- }
- if (soap->error == SOAP_TAG_MISMATCH)
- soap->error = soap_ignore_element(soap);
- if (soap->error == SOAP_NO_TAG)
- break;
- if (soap->error)
- return NULL;
- }
- if (soap_element_end_in(soap, tag))
- return NULL;
- }
- else
- { a = (struct SOAP_ENV__Header *)soap_id_forward(soap, soap->href, (void*)a, 0, SOAP_TYPE_SOAP_ENV__Header, 0, sizeof(struct SOAP_ENV__Header), 0, NULL);
- if (soap->body && soap_element_end_in(soap, tag))
- return NULL;
- }
- return a;
- }
-
- 服務端程序如下，到這里就沒什么難度了，基本上與上一節的服務端結構差不多，注意要把幾個pem證書拷貝過來（因為usernametoken方式通常都是基于HTTPS的），echo接口和show_version接口都要編寫：
-
#include <pthread.h>
#include "soapH.h"
#include "SecureEchoHttpBinding.nsmap"
void *process_request(void *soap) {
pthread_detach(pthread_self());
if ( soap_ssl_accept((struct soap *) soap) != SOAP_OK )
soap_print_fault((struct soap *) soap, stderr);
else
soap_serve((struct soap *) soap);
soap_end((struct soap *) soap);
soap_free((struct soap *) soap);
return NULL;
}
int main(int argc, char **argv) {
if ( argc != 2 ) {
printf("Usage: %s port\n", argv[0]);
exit(-1);
}
int port = atol(argv[1]);
pthread_t tid;
struct soap *tsoap;
struct soap soap;
soap_init(&soap);
soap_ssl_init();
if ( soap_ssl_server_context(&soap, SOAP_SSL_DEFAULT, "server.pem", "password", "cacert.pem", NULL, "dh512.pem", NULL, argv[0]) ) {
soap_print_fault(&soap, stderr);
exit(-1);
}
int m, s;
if ( (m = soap_bind(&soap, NULL, port, 100)) < 0 ) {
soap_print_fault(&soap, stderr);
}
else {
printf("Socket connect successfully: master socket = %d\n", m);
int i = 0;
while ( 1 ) {
if ( (s = soap_accept(&soap)) < 0 ) {
soap_print_fault(&soap, stderr);
break;
}
printf("Connection %d accepted from IP = %d.%d.%d.%d, slave socket = %d\n", ++i, (soap.ip >> 24) & 0xff, (soap.ip >> 16) & 0xff, (soap.ip >> 8) & 0xff, soap.ip & 0xff, s);
tsoap = soap_copy(&soap);
if ( !tsoap ) {
soap_closesock(&soap);
continue;
}
pthread_create(&tid, NULL, &process_request, (void *) tsoap);
}
}
soap_done(&soap);
return 0;
}
int __ns1__sendEcho(
struct soap *soap,
struct _ns1__sendEcho *request,
struct _ns1__sendEchoResponse *response) {
if ( !soap->header || !soap->header->wsse__username || !soap->header->wsse__password || !soap->header->ns1__customerId
|| strcmp(soap->header->wsse__username, "roy") || strcmp(soap->header->wsse__password, "liang")
|| strcmp(soap->header->ns1__customerId, "G06164"))
return 401;
int len = strlen(request->message);
response->out = (char *) malloc(sizeof(char) * (len + 1));
strcpy(response->out, request->message);
return SOAP_OK;
}
int __ns1__showVersionInformation(
struct soap *soap,
struct _ns1__showVersionInformation *request,
struct _ns1__showVersionInformationResponse *response) {
if ( !soap->header || !soap->header->wsse__username || !soap->header->wsse__password || !soap->header->ns1__customerId
|| strcmp(soap->header->wsse__username, "roy") || strcmp(soap->header->wsse__password, "liang")
|| strcmp(soap->header->ns1__customerId, "G06164"))
return 401;
response->out = (char *) malloc(sizeof(char) * 100);
strcpy(response->out, "Username token (text) test server version 1.0");
return SOAP_OK;
}
-
- 服務端程序保存為secure_echo_server.c，編譯命令是
- gcc -DWITH_OPENSSL -O2 -o secure_echo_server secure_echo_server.c soapC.c soapServer.c ../../stdsoap2.c -I../.. -L../.. -lgsoap -lssl –lcrypto
-
- 運行測試，在6883端口啟動服務端，然后執行客戶端
- -bash-3.2$ ./show_version roy liang G06164
- username : roy
- password : liang
- customer id : G06164
- Username token (text) test server version 1.0
-
- -bash-3.2$ ./secure_echo roy liang G06164 hello
- username : roy
- password : liang
- customer id : G06164
- message : hello
- hello
-
- 以上就是gSOAP實現Usernametoken認證的方法，而且是通過自定義SOAP header實現的。個人認為，與使用wsse插件相比，這種方法更為簡單直接。
-
- 另外，本案例的方法適用于以明文傳送密碼的情況，如果需要以摘要(digest)形式傳送密碼，請參考plugin目錄wsseapi.c里面的soap_wsse_add_UsernameTokenDigest函數。
