SMP 3.0 OData CRUD Operations in iOS Native

[Former Member]

Hi Everyone,

Recently i gone through OData Read, Create, Update and Delete operations in SMP 3.0 Native ODataSDK.

here is a sample code for a OData service

http://sapes1.sapdevcenter.com:8080/sap/opu/odata/IWFND/RMTSAMPLEFLIGHT/TravelagencyCollection

GET Request Format

[RequestBuilder setRequestType:HTTPRequestType];

// Enable XCSRF handling for OData requests

[RequestBuilder enableXCSRF:YES];

// Initialize the Requesting class with the endpoint URL

id<Requesting> getRequest = [RequestBuilder requestWithURL:[[NSURL alloc] initWithString: appEndPoint]];

// Add username and password for the end point

[getRequest setUsername:username];

[getRequest setPassword:password];

/// Set our request headers.

[getRequest setRequestMethod:@"GET"];

[getRequest addRequestHeader:@"X-Requested-With" value:@"XmlHttpRequest"];

[getRequest addRequestHeader:@"Content-Type" value:@"application/xml; charset=UTF-8"];

[getRequest addRequestHeader:@"Accept" value:@"application/xml,application/atom+xml"];

// This class is the delegate callback for any notifications (success and failure)

[getRequest setDelegate:self];

[getRequest setDidFinishSelector:@selector(handleReqSuccess:)];

[getRequest setDidFailSelector:@selector(handleReqFailed:)];

// Each request can be tagged with a number.

getRequest.requestTag = tag; // Useful for a change request.

// Start our request.

[getRequest startAsynchronous];

POST Request Format

[RequestBuilder setRequestType:HTTPRequestType];

[RequestBuilder enableXCSRF:YES];

id<Requesting> postRequest = [RequestBuilder requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"%@/%@",appEndPoint,collectionName]]];

[postRequest setRequestMethod:@"POST"];

[postRequest addRequestHeader:@"Content-Type" value:@"application/json; charset=UTF-8"];

[postRequest addRequestHeader:@"Accept" value:@"*/*"];

// Here cSRFToken is retrieved from the GET Response.

[postRequest addRequestHeader:@"x-csrf-token" value: cSRFToken];

NSMutableData* postData;

// GetEntry is an ODataObject which has the response for GET done on single entry from a collection

ODataEntry const *postBody = [[ODataEntry alloc]initWithEntitySchema:[[[self.serviceDocument getSchema] getCollectionByName:self.entityName] getEntitySchema]];

ODataPropertyValueObject* filterValue = [postBody getPropertyValueByPath:@"agencynum"];  ///agencynum is the primary key or the unique value

          filterValue.rawValue=@"00000127";

ODataPropertyValueObject* filterValue1 = [postBody getPropertyValueByPath:@"agencyname"];

filterValue1.rawValue=@"BestAgency";

//The following code can be used to build a JSON post body:

ODataEntryBody *entryBody = buildODataEntryRequestBody(postBody, ENTRY_OPERATION_CREATE, self.serviceDocument, NO, BUILD_STYLE_JSON);  

postData = [[entryBody.body dataUsingEncoding:NSUTF8StringEncoding]mutableCopy];

[postRequest addRequestHeader:@"Content-Length" value:[NSString stringWithFormat:@"%i",[postData length]]];

[postRequest setPostBody:postData];

[postRequest setDelegate:self];

// Each request can be tagged with a number.

          getRequest.requestTag = tag; // Useful for a change request.

// Start our request.

[postRequest startAsynchronous];

PUT Request Format

[RequestBuilder setRequestType:HTTPRequestType];

[RequestBuilder enableXCSRF:YES];

id<Requesting> putRequest = [RequestBuilder requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"%@/%@(%@)",appEndPoint,collectionName,agencynum]]];

[putRequest setRequestMethod:@"PUT"];

[putRequest addRequestHeader:@"Content-Type" value:@"application/json; charset=UTF-8"];

[putRequest addRequestHeader:@"Accept" value:@"*/*"];

[putRequest addRequestHeader:@"x-csrf-token" value:cSRFToken];

NSMutableData *postData;

ODataEntry const *postBody = [[ODataEntry alloc]initWithEntitySchema:[[[self.serviceDocument getSchema] getCollectionByName:self.entityName] getEntitySchema]];

ODataPropertyValueObject* filterValue = [postBody getPropertyValueByPath:@"agencyname"];

filterValue.rawValue=@"NewAgencyName";

//The following code can be used to build a JSON post body:

ODataEntryBody *entryBody = buildODataEntryRequestBody(postBody, ENTRY_OPERATION_CREATE, self.serviceDocument, NO, BUILD_STYLE_JSON);

postData = [[entryBody.body dataUsingEncoding:NSUTF8StringEncoding]mutableCopy];

[putRequest addRequestHeader:@"Content-Length" value:[NSString stringWithFormat:@"%i",[postData length]]];

[putRequest setPostBody:postData];

[putRequest setDelegate:self];

putRequest.requestTag = tag;

// Start our request.

  [putRequest startAsynchronous];

DELETE Request Format

[RequestBuilder setRequestType:HTTPRequestType];

[RequestBuilder enableXCSRF:YES];

id<Requesting> deleteRequest = [RequestBuilder requestWithURL:[NSURL URLWithString:[NSString stringWithFormat@"%@/%@(%@)",appEndPoint,collectionName,agencynum]]];

[deleteRequest setRequestMethod:@"Delete"];

[deleteRequest addRequestHeader:@"Content-Type" value:@"application/json; charset=UTF-8"];

[deleteRequest addRequestHeader:@"Accept" value:@"*/*"];

[deleteRequest addRequestHeader:@"x-csrf-token" value:self.cSRFToken];

[deleteRequest setDelegate:self];

deleteRequest.requestTag = tag;

// Start our request.

[deleteRequest startAsynchronous];
