有人可以帮我解决以下问题:
尝试通过SUP通过ODATA渠道服务从iPad应用程序连接到SAP ECC系统时,它允许我第一次登录并可以从SAP系统成功检索数据。但是当我注销并尝试使用相同的会话再次登录时,应用程序会崩溃。以下是崩溃报告供您参考。
我正在使用SDM Parser连接SAP系统。
SDMODataServiceDocumentParser *sdmDocParser = [[SDMODataServiceDocumentParser alloc] init];
[sdmDocParser parse:aServiceDocument];
m_serviceDocument = sdmDocParser.serviceDocument;
//Load the object with metadata xml:
SDMODataMetaDocumentParser *sdmMetadataParser = [[SDMODataMetaDocumentParser alloc] initWithServiceDocument:m_serviceDocument];
[sdmMetadataParser parse:aMetadata];
启动服务后,设置网址。
[service setServiceDocumentUrl:m_serviceDocumentURL];
使用SDMconnectivityhelper连接网址
id<SDMRequesting> serviceDocumentRequest2 = [connectivityHelper executeBasicSyncRequestWithQuery3:[[ODataQuery alloc]initWithURL:[NSURL URLWithString:encodedStrUrl]]] ;
- (id <SDMRequesting>)executeBasicSyncRequestWithQuery3:(ODataQuery *)aQuery
{
id<SDMRequesting> request = [self createRequestWithQuery:aQuery];
[request setTimeOutSeconds:TIMEOUT_SEC];
[request setRequestMethod:@"GET"];
[request addRequestHeader:@"Content-Type" value:@"application/xml"];
[request startSynchronous];**[App getting CRASH in this line]**
return request;
}
- (id <SDMRequesting>)createRequestWithQuery:(ODataQuery *)aQuery
{
if (isSUPMode)
{
[SDMRequestBuilder setRequestType:SUPRequestType];
}
else
{
[SDMRequestBuilder setRequestType:HTTPRequestType];
}
id <SDMRequesting> request = [SDMRequestBuilder requestWithURL:aQuery.URL];
request.username = self.username;
request.password = self.password;
return request;
}
