Translate curl command to NSURLRequest
Translate curl command to NSURLRequest

I have the following curl command to a web api, which retrieves some info:
curl -X GET -H 'Authorization: Basic blabla' -H 'Content-Type: application/xml; charset=utf-8' -H 'Accept-Language: en' -d "<user><account_attributes><email>email@hidden</email><password>SomePassWord</password></account_attributes></user>" 'https://example.com/api/v1/endpoint
The -d and xml-string are mandatory for this GET command. I haven’t been able to translate this into an equivalent NSURLRequest that gets accepted by the server.
I tried this:
NSURLCredential *credential = [[WRTSServerEngine sharedServerEngine] savedCredentialsForHost:@“example.com"
port:0
protocol:@"https"
realm:@“SomeRealm"];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:@"https://example.com/api/v1/endpoint";]];
NSString *authStr = [NSString stringWithFormat:@"%@:%@", credential.user, credential.password];
NSData *authData = [authStr dataUsingEncoding:NSUTF8StringEncoding];
NSString *authValue = [NSString stringWithFormat: @"Basic %@",[authData base64EncodedStringWithOptions:0]];
[request setValue:authValue forHTTPHeaderField:@"Authorization"];
NSString *infoAsXMLString = @"<user>";
infoAsXMLString = [infoAsXMLString stringByAppendingString:@"<account_attributes>"];
infoAsXMLString = [infoAsXMLString stringByAppendingFormat:@"<email>%@</email>", credential.user];
infoAsXMLString = [infoAsXMLString stringByAppendingFormat:@"<password>%@</password>", credential.password];
infoAsXMLString = [infoAsXMLString stringByAppendingString:@"</account_attributes>"];
infoAsXMLString = [infoAsXMLString stringByAppendingString:@"</user>"];
[request setHTTPBody:[infoAsXMLString dataUsingEncoding:NSUTF8StringEncoding]];
NSURLSessionConfiguration *sessionConfig = [NSURLSessionConfiguration defaultSessionConfiguration];
sessionConfig.allowsCellularAccess = YES;
[sessionConfig setHTTPAdditionalHeaders:@{@"Accept": @"application/xml"}];
NSURLSession *session = [NSURLSession sessionWithConfiguration:sessionConfig];
self.task = [session dataTaskWithRequest:request
completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
NSLog(@"%@", error);
}];
[self.task resume];
This results in the following error:
Error Domain=NSURLErrorDomain Code=-1005 "The network connection was lost." UserInfo=0x7ffd0b5f7a00 {NSUnderlyingError=0x7ffd0b58be50 "The operation couldn’t be completed. (kCFErrorDomainCFNetwork error -1005.)", NSErrorFailingURLStringKey=https://staging.wrts.nl/api/v1/existing_user, NSErrorFailingURLKey=https://staging.wrts.nl/api/v1/existing_user, _kCFStreamErrorDomainKey=4, _kCFStreamErrorCodeKey=-4, NSLocalizedDescription=The network connection was lost.}
If I do not set an HHTPBody on the request, I get a 500 error (which makes sense, since the server is expecting a payload in the body).
Is there a way to see exactly what the request looks like when it goes out? Is there a way to create the request such that it is equivalent to the curl command at the top of this post?
Thanks,
António
