AFNetworking 2.0 Send Post Request with array of dictionary Parameters - ios

Question

I want to try post parameter in the following API but the parameter is not getting passed properly, and the response received gives the message that, data is required. So can anyone please help to sort out this problem.
my url is
forapp.com/api/getContacts.php?data=[
{"name":"abc","phone":"1234567890"},{"name":"Kate
Bell","phone":"9925992599"} ]
so how i can pass this type of request to the api
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *params = #{#"name": #"hello",
#"phone": #"1234567890"};
NSLog(#"Dict %#",params);
manager.responseSerializer.acceptableContentTypes = [manager.responseSerializer.acceptableContentTypes setByAddingObject:#"text/html"];
[manager POST:#"http://forapp.com/api/getContacts.php" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];

Answer 1

just add
Step-1
// create the dictionary of {"name":"abc","phone":"1234567890"},{"name":"Kate Bell","phone":"9925992599"} this
NSDictionary *params = #{#"name": #"hello",
#"phone": #"1234567890"};
Step-2
//create the one array of this output [ {"name":"abc","phone":"1234567890"},{"name":"Kate Bell","phone":"9925992599"} ]
NSMutableArray *arr = [NSMutableArray arrayWithObjects:params,nil];
Step-3
// convert your object to JSOn String
NSError *error = nil;
NSString *createJSON = [[NSString alloc] initWithData:[NSJSONSerialization dataWithJSONObject:objectsInCart
options:NSJSONWritingPrettyPrinted
error:&error]
encoding:NSUTF8StringEncoding];
Step-4
//create the another one dictionary for send the data for like data=[ {"name":"abc","phone":"1234567890"},{"name":"Kate Bell","phone":"9925992599"} ]
NSDictionary *pardsams = #{#"data": createJSON};
Step-5
// finally start your request
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSLog(#"Dict %#",pardsams);
manager.responseSerializer.acceptableContentTypes = [manager.responseSerializer.acceptableContentTypes setByAddingObject:#"text/html"];
[manager POST:#"http://forapp.com/api/getContacts.php" parameters:pardsams success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];

Answer 2

as per this url
forapp.com/api/getContacts.php?data=[ {"name":"abc","phone":"1234567890"},{"name":"Kate Bell","phone":"9925992599"} ]
You should implement like this
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *params = #{#"name": #"hello",
#"phone": #"1234567890"};
NSLog(#"Dict %#",params);
manager.responseSerializer = [AFJSONResponseSerializer serializer];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
manager.responseSerializer.acceptableContentTypes = [manager.responseSerializer.acceptableContentTypes setByAddingObject:#"text/html"];
[manager POST:#"http://forapp.com/api/getContacts.php" parameters:#{#"data": #[params]} success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];

Add following:
// httpClient is a subclass of AFHTTPRequestOperationManager or AFHTTPSessionManager
httpClient.requestSerializer = AFJSONRequestSerializer;
And also check your post array does not include any other object. It just include array.
