In Objective C how should I write a Double Nested Response Body along the form:
{'ms_request':
{'user':
{'api_key':'',
'username':'',
'password':''
}
}
}
I know how to do it for one object, but double nesting the objects has me stumped.
Here is what I have so far:
NSArray *loginDetails = [self authenticationHelper];
NSDictionary *tmp = [[NSDictionary alloc] initWithObjectsAndKeys:
[loginDetails objectAtIndex:0], #"password",
[loginDetails objectAtIndex:1], #"username",
[loginDetails objectAtIndex:2], #"api_key",
nil];
NSError *error;
NSData *postdata = [NSJSONSerialization dataWithJSONObject:tmp options:0 error:&error];
NSMutableURLRequest *request =
[[NSMutableURLRequest alloc] initWithURL:
[NSURL URLWithString:autheticationURL]];
[request setHTTPMethod:#"POST"];
[request setHTTPBody:postdata];
You could also use NSDictionary literals. Something like this (just make sure that you check all the values to avoid insertion of nil objects):
NSDictionary *reqDict =
#{#"ms_request":
#{#"user":
#{#"api_key":loginDetails[2],
#"username":loginDetails[1],
#"password":loginDetails[0]
}
}
};
You have to add dictionary in another dictionary.
NSDictionary *tmp = [[NSDictionary alloc] initWithObjectsAndKeys:
[loginDetails objectAtIndex:0], #"password",
[loginDetails objectAtIndex:1], #"username",
[loginDetails objectAtIndex:2], #"api_key",
nil];
NSDictionary *userDict = [[NSDictionary alloc] initWithObjectsAndKeys:
tmp, #"user"];
NSDictionary *requestDict = [[NSDictionary alloc] initWithObjectsAndKeys:
userDict, #"ms_request"];
NSData *postdata = [NSJSONSerialization dataWithJSONObject:requestDict options:0 error:&error];
PS: In JSON, { } represents dictionary and [ ] represents array.

how i can create Dictionary that when i create jsondata with it, json looks like :
"historyStep":[
{
"counter": "50",
"timestamp": "1461674383632"
}
]
I did this :
NSMutableDictionary*jsonDictOth = [[NSMutableDictionary alloc]init];
[jsonDictOth setObject:#(810) forKey:#"counter"];
[jsonDictOth setObject:#"1464957395241.447998" forKey:#"timestamp"];
NSMutableDictionary *jsonDictMain = [[NSMutableDictionary alloc]initWithObjectsAndKeys:jsonDictOth,#"historyStep", nil];
NSError*error;
NSData *data = [NSJSONSerialization dataWithJSONObject:jsonDictMain
options:NSJSONWritingPrettyPrinted
error:&error];
but it looks :
historyStep = {
counter = 810;
timestamp = "1464957395241.447998";
};
You are missing a level: NSDictionary (top level) with NSArray of NSDictionary in the top level key historyStep:
NSMutableDictionary *topLevel = [[NSMutableDictionary alloc] init];
NSArray *historySteps = [[NSMutableArray alloc] init];
//Here you may have a for loop in case there are more steps
NSDictionary *aStep = #{#"counter":#"50", #"timestamp":#"1461674383632"};
[historySteps addObject:aStep]
[topLevel setObject:historySteps forKey#"historyStep"];
NSError*error;
NSData *data = [NSJSONSerialization dataWithJSONObject:topLevel
options:NSJSONWritingPrettyPrinted
error:&error];
NSDictionary *innerDictionary = [[NSDictionary alloc]initWithObjectsAndKeys:#"50", #"counter",#"1461674383632", #"timestamp", nil];
NSArray *array = [[NSArray alloc]initWithObjects:innerDictionary, nil];
NSDictionary *outerDict = [[NSDictionary alloc]initWithObjectsAndKeys:array, #"historyStep", nil];
Use this code it will work perfectly.
Your code should be like,
NSMutableDictionary*jsonDictOth = [[NSMutableDictionary alloc]init];
[jsonDictOth setObject:#(810) forKey:#"counter"];
[jsonDictOth setObject:#"1464957395241.447998" forKey:#"timestamp"];
NSMutableArray *arr = [[NSMutableArray alloc]init];
[arr addObject:jsonDictOth];
NSMutableDictionary *jsonDictMain = [[NSMutableDictionary alloc]initWithObjectsAndKeys:arr,#"historyStep", nil];
NSLog(#"jsonMain is %#",jsonDictMain);
NSError*error;
NSData *data = [NSJSONSerialization dataWithJSONObject:jsonDictMain
options:0
error:&error];
It's output is,
jsonMain is {
historyStep = (
{
counter = 810;
timestamp = "1464957395241.447998";
}
);
}
You just missed one array between
How to send parameters in json format?
Below are my input parameters :
[
{
"LoginID":151,
"UserID":0,
"SubUserID":0,
"WorkGroupID":92,
"WorksFor":"Doctor",
"UserWorkGroup":0
},
{
"SortingName":"",
"Searching":true,
"SortingOrder":"Desc",
"RecordsCount":10,
"PageIndex":0
}
]
Previously I was sending parameters as below :
[getProfileServices sendSynchronousPostRequestWithStringForAction:getProfileURL andParameters:[[NSDictionary alloc] initWithObjectsAndKeys:#"55",#"LoginID",#"0",#"UserID",#"0",#"SubUserID",#"90",#"WorkGroupID",#"Doctor",#"WorksFor",#"0",#"UserWorkGroup",nil] andRequestType:#"POST"];
how to sent like this but now i need to add some more input mentioned above ?
Just use following code..
NSMutableArray * myArray = [[NSMutableArray alloc]init];
NSMutableDictionary * myData = [[NSMutableDictionary alloc]init];
[myData setValue:#"151" forKey:#"LoginID"];
[myData setValue:#"0" forKey:#"UserID"];
[myData setValue:#"0" forKey:#"SubUserID"];
[myData setValue:#"92" forKey:#"WorkGroupID"];
[myData setValue:#"Doctor" forKey:#"WorksFor"];
[myData setValue:#"0" forKey:#"UserWorkGroup"];
[myArray addObject:myData];
myData = [[NSMutableDictionary alloc]init];
[myData setValue:#"," forKey:#"SortingName"];
[myData setValue:#"1" forKey:#"Searching"];
[myData setValue:#"Desc" forKey:#"SortingOrder"];
[myData setValue:#"10" forKey:#"RecordsCount"];
[myData setValue:#"0" forKey:#"PageIndex"];
[myArray addObject:myData];
NSData *jsonData2 = [NSJSONSerialization dataWithJSONObject:myArray options:NSJSONWritingPrettyPrinted error:nil];
NSString *jsonString = [[NSString alloc] initWithData:jsonData2 encoding:NSUTF8StringEncoding];
NSLog(#"Your final jsonData as string:\n%#", jsonString);
If you want to send this data to Server, then you can use this code:
NSData *dataToSend = [NSJSONSerialization dataWithJSONObject:myArray options:0 error:nil];
[getProfileServices sendSynchronousPostRequestWithStringForAction:getProfileURL andParameters:[[NSDictionary alloc] initWithObjectsAndKeys:dataToSend] andRequestType:#"POST"];
You can do something like this,
NSDictionary *dict1 = #{#"LoginID":#"151",#"UserID":#"0",#"SubUserID":#"0",#"WorkGroupID":#"92",#"WorksFor":#"Doctor",#"UserWorkGroup":#"0"};
NSDictionary *dict2 = #{#"SortingName":#",",#"Searching":#"true",#"SortingOrder":#"Desc",#"RecordsCount":#"10",#"PageIndex":#"0"};
NSArray *arr = [NSArray arrayWithObjects:dict1,dict2, nil];
NSData *dataToSend = [NSJSONSerialization dataWithJSONObject:arr options:0 error:nil];
[getProfileServices sendSynchronousPostRequestWithStringForAction:getProfileURL andParameters:[[NSDictionary alloc] initWithObjectsAndKeys:dataToSend andRequestType:#"POST"];
Hope this will help :)
add it in NSMutableArray and add that array to NSDictionary. like;
{"LoginID":151,"UserID":0,"SubUserID":0,"WorkGroupID":92,"WorksFor":"Doctor","UserWorkGroup":0}
this goes in NSMutableArray and NSMutableArray goes to NSDictionary
Simple way to put array into the dictionary is
#{#[element],#[element],#[element]}
I want to create a JSON array of the following structure:
"Create Account":{
"RegistryNumber":"",
"People":[{
"PeopleId":"",
"email":"",
"pass":"",
}]
}
I am using the folllowing code to do it:
NSDictionary *content0 = [NSDictionary dictionaryWithObjectsAndKeys:
#"PeopleId", #"0",
#"email", #"email",
#"pass", #"pass",nil];
NSArray *peopledetails = [NSArray arrayWithObjects:content0,nil];
NSMutableDictionary *peopleDict = [[NSMutableDictionary alloc] init];
[peopleDict setObject:#"content0" forKey:#"People"];
NSMutableDictionary *details = [[NSMutableDictionary alloc] init];
[details setObject:#"RegistryNumber" forKey:#"RegistryNumber"];
[details setObject:#"peopleDict" forKey:#"People"];
NSMutableDictionary *MainDict = [[NSMutableDictionary alloc] init];
[MainDict setObject:#"details" forKey:#"Create Account"];
But this gives me an error from the server. I have other API which works fine when array is not in picture.
- (void)simpleJsonParsing
{
// URL request with server
NSHTTPURLResponse *response = nil;
NSString *jsonUrlString = [NSString stringWithFormat:#"URL"];
NSURL *url = [NSURL URLWithString:[jsonUrlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
//-- Get request and response though URL
NSURLRequest *request = [[NSURLRequest alloc]initWithURL:url];
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:nil];
//-- JSON Parsing
NSMutableArray *result = [NSJSONSerialization JSONObjectWithData:responseData options:NSJSONReadingMutableContainers error:nil];
NSLog(#"Result = %#",result);
for (NSMutableDictionary *dic in result)
{
NSString *string = dic[#"Create Account"];
if (string)
{
NSData *data = [string dataUsingEncoding:NSUTF8StringEncoding];
dic[#"Create Account"] = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];
}
else
{
NSLog(#"Error in response");
}
}
}
change
[peopleDict setObject:#"content0" forKey:#"People"];
to
[peopleDict setObject:peopledetails forKey:#"People"];
Remove all #"" for objects.
#"details" is a string and details is an object
Or here is the simple way
NSDictionary *dict=#{
#"Create Account": #{
#"RegistryNumber": #"",
#"People": #[
#{
#"PeopleId": #"",
#"Email": #"",
#"pass":#""
}
]
}
};
I think you have wrong structure
NSDictionary *content0 = [NSDictionary dictionaryWithObjectsAndKeys:
#"PeopleId", #"0",
#"email", #"email",
#"pass", #"pass",nil];
postDict = #{#"Create Account":#{#"RegistryNumber":"","People":content0}}
now convert this into jason and send to your server
I have an Array of Roll Numbers
NSArray *rollArray = [NSArray arrayWithObjects:#"1", #"22", #"24", #"11", nil];
I need to send this array in a Web Service request
whose format is like this (in JSON format)
JSON data
{
"existingRoll":["22","34","45","56"], // Array of roll numbers
"deletedRoll":["20","34","44","56"] // Array of roll numbers
}
but I am facing problem in converting Array of Roll numbers (rollArray) into json String
in the desired format.
I am trying this
NSMutableDictionary *postDict = [[NSMutableDictionary alloc]init];
[postDict setValue:[rollArray componentsJoinedByString:#","] forKey:#"existingRoll"];
NSString *str = [Self convertToJSONString:postDict]; // converts to json string
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:str options:0 error:nil];
[request setHTTPBody:jsonData];
I am using iOS 7
There is no need to use the following code snippets:
[rollArray componentsJoinedByString:#","]
NSString *str = [Self convertToJSONString:postDict];
You can create JSON by using the following code:
NSArray *rollArray = [NSArray arrayWithObjects:#"1", #"22", #"24", #"11", nil];
NSMutableDictionary *postDict = [[NSMutableDictionary alloc]init];
[postDict setValue:rollArray forKey:#"existingRoll"];
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:postDict options:0 error:nil];
// Checking the format
NSLog(#"%#",[[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding]);
Try this :
NSDictionary *object = #{
#"existingRoll":#[#"22",#"34",#"45",#"56"],
#"deletedRoll":#[#"20",#"34",#"44",#"56"]
};
if ([NSJSONSerialization isValidJSONObject:object]) {
NSData* data = [ NSJSONSerialization dataWithJSONObject:object options:NSJSONWritingPrettyPrinted error:nil ];
NSString *str = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(str);
}
NSMutableDictionary *postDict = [[NSMutableDictionary alloc] init];
[postDict setValue:#"Login" forKey:#"methodName"];
[postDict setValue:#"admin" forKey:#"username"];
[postDict setValue:#"12345" forKey:#"password"];
[postDict setValue:#"mobile" forKey:#"clientType"];
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:postDict options:0 error:nil];
// Checking the format
NSString *urlString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
// Convert your data and set your request's HTTPBody property
NSString *stringData = [[NSString alloc] initWithFormat:#"jsonRequest=%#", urlString];
//#"jsonRequest={\"methodName\":\"Login\",\"username\":\"admin\",\"password\":\"12345\",\"clientType\":\"web\"}";
NSData *requestBodyData = [stringData dataUsingEncoding:NSUTF8StringEncoding];
You can use following method to get Json string from any type of NSArray :
NSArray *rollArray = [NSArray arrayWithObjects:#"1", #"22", #"24", #"11", nil];
NSData *data = [NSJSONSerialization dataWithJSONObject:rollArray options:0 error:nil];
NSString *jsonString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(#"Json string is: %#", jsonString);
I get the data from an XML file and I am storing it in NSData object. I want to convert that NSData into an NSDictionary and store that data in a plist.
My code is as follows:
NSURL *url = [NSURL URLWithString:#"http://www.fubar.com/sample.xml"];
NSData *data = [NSData dataWithContentsOfURL:url];
NSLog(#"%#", data);
To convert the data, I am using:
- (NSDictionary *)downloadPlist:(NSString *)url {
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:url] cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:10];
NSURLResponse *resp = nil;
NSError *err = nil;
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&resp error:&err];
if (!err) {
NSString *errorDescription = nil;
NSPropertyListFormat format;
NSDictionary *samplePlist = [NSPropertyListSerialization propertyListFromData:responseData mutabilityOption:NSPropertyListImmutable format:&format errorDescription:&errorDescription];
if (!errorDescription)
return samplePlist;
[errorDescription release];
}
return nil;
}
Can anyone please tell me how to do that?
or this:
NSString* dataStr = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
SBJSON *jsonParser = [SBJSON new];
NSDictionary* result = (NSDictionary*)[jsonParser objectWithString:dataStr error:nil];
[jsonParser release];
[dataStr release];
Try this code:
NSString *newStr1 = [[NSString alloc] initWithData:theData1 encoding:NSUTF8StringEncoding];
NSString *newStr2 = [[NSString alloc] initWithData:theData2 encoding:NSUTF8StringEncoding];
NSString *newStr3 = [[NSString alloc] initWithData:theData3 encoding:NSUTF8StringEncoding];
NSArray *keys = [NSArray arrayWithObjects:#"key1", #"key2", #"key3", nil];
NSArray *objects = [NSArray arrayWithObjects:newStr1 , newStr2 , newStr3 , nil];
NSDictionary *dictionary = [NSDictionary dictionaryWithObjects:objects forKeys:keys];
for (id key in dictionary) {
NSLog(#"key: %#, value: %#", key, [dictionary objectForKey:key]);
}
NSString *path = [[NSBundle mainBundle] pathForResource:#"Login" ofType:#"plist"];
[dictionary writeToFile:path atomically:YES];
//here Login is the plist name.
Happy coding
