qt用http协议访问webservice，用crypto的sha256签名

http://blog.csdn.net/stronghill/article/details/48731253

代码如下

[cpp] view plain copy

1. int Form::getUserFee(const QString& userNo)  
2. {  
3.   
4.     QString sUrl = "http://192.168.0.102:8430/systemsoa/services/ChargeService.ChargeServiceHttpSoap12Endpoint/";  
5.             //sUrl += "getUserTotalArrear?bankCode=08&chgBranch=02129&chgTellerId=02754&userNo=123";  
6.             //sUrl += "getUserTotalArrear";  
7.     //QUrl::toPercentEncoding(sUrl);//进行url编码  
8.   
9.     QString bankCode = "08";  
10.     QString chgBranch = "02129";  
11.     QString chgTellerId = "02754";  
12.     int tag = 0;  
13.         //QString url = "http://192.168.0.102:8430/systemsoa/services/ChargeService.ChargeServiceHttpSoap12Endpoint/";  
14.     QString key = "7bf6e35f7a7fe23c891d395a74382b64";

16.     QString orderId = "20150923135600";  
17.     QString orders = "20150902135603";  
18.   
19.     LogUtil::info("FormEc.getUserFee,userNo=" + userNo);  
20.     CryptoPP::SHA256 sha256;  
21.     //int DigestSize = sha256.DigestSize();  
22.     char byDigest[32];  
23.     QString aa = "0124";  
24.     aa = "bankcode=" + bankCode + "&chgbranch=" + chgBranch + "&chgteller=" + chgTellerId +"&orderid=" + orderId  
25.             + "&userno=" + userNo + "&key=" + key;  
26.     sha256.CalculateDigest((byte*)byDigest, (byte*)aa.toAscii().data(), aa.toAscii().length());  
27.     QByteArray ba = QByteArray::fromRawData(byDigest, 32);  
28.   
29.     LogUtil::info("FormEc.getUserFee,sha=" + QString(ba.toHex()));  
30.   
31.     QString content = QString("<soap:Envelope xmlns:soap=\"http://www.w3.org/2003/05/soap-envelope\" ")  
32.                 + "xmlns:web=\"http://webservice.netcharge.ysxn.com\" xmlns:xsd=\"http://model.netcharge.ysxn.com/xsd\">"  
33.                 + "<soap:Header/>"

46.     //content = "<soap:Envelope xmlns:soap=\"http://www.w3.org/2003/05/soap-envelope\"><soap:Body/></soap:Envelope>";  
47.   
48.   
49.     //LogUtil::info("FormEc.getUserFee,content=" + content);  
50.     ecCode = "3001";  
51.     QNetworkRequest nr;  
52.     nr.setUrl(sUrl);  
53.     nr.setHeader(QNetworkRequest::ContentTypeHeader, " application/soap+xml;charset=UTF-8;action=\"urn:getUserTotalArrear\"");  
54.     netManager->post(nr, content.toAscii());  
55.     connect(netManager, SIGNAL(finished(QNetworkReply*)),  this, SLOT(getUserFeeNet(QNetworkReply*)));  
56.   
57.     return 0;  
58.   
59. }  
60.   
61. void Form::getUserFeeNet(QNetworkReply* reply)  
62. {  
63.     QByteArray rdata = reply->readAll();  
64.     QString sret = QString::fromLocal8Bit(rdata.data());  
65.     LogUtil::info("FormEc.getUserFeeNet,reply=" + sret);  
66. }  

另外，这个是用qtcreator创建的工程，要想链接crypto，在pro文件中增加了LIBS +=   -lcryptopp -lpthread
