I am calling a web service in iOS. For this, I need to set the header in NSMutableURLRequest object. My service takes two string parameters and returns data in JSON format.
What are the the fields that I need to set in the header (Both while using GET and POST) using the setValue:forHTTPHeaderField:.
We do not need to use setHTTPBody: while using GET.. right???
I had the same question and I resolved (using some code from Iducool and Ankit Mehta) like this...
NSURL *theURL = [NSURL URLWithString:#"yourURL"];
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:theURL cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:20.0f];
//Specify method of request(Get or Post)
[theRequest setHTTPMethod:#"GET"];
//Pass some default parameter(like content-type etc.)
[theRequest setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[theRequest setValue:#"application/json; charset=UTF-8" forHTTPHeaderField:#"Content-Type"];
//Now pass your own parameter
[theRequest setValue:yourValue forHTTPHeaderField:theNameOfThePropertyValue];
NSURLResponse *theResponse = NULL;
NSError *theError = NULL;
NSData *theResponseData = [NSURLConnection sendSynchronousRequest:theRequest returningResponse:&theResponse error:&theError];
//Now you can create a NSDictionary with NSJSONSerialization
NSDictionary *dataDictionaryResponse = [NSJSONSerialization JSONObjectWithData:theResponseData options:0 error:&theError];
NSLog(#"url to send request= %#",theURL);
NSLog(#"%#",dataDictionaryResponse);
Look at this code which i am using to call a web service and thats working for me
+(NSString *)http_post_method_changed:(NSString *)url content:(NSString *)jsonContent{
NSURL *theURL = [NSURL URLWithString:url];
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:theURL cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:20.0f];
NSData *requestData = [jsonContent dataUsingEncoding:NSUTF8StringEncoding];
[theRequest setHTTPMethod:#"POST"];
[theRequest setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[theRequest setValue:#"application/json; charset=UTF-8" forHTTPHeaderField:#"Content-Type"];
[theRequest setValue:[NSString stringWithFormat:#"%d", [requestData length]] forHTTPHeaderField:#"Content-Length"];
[theRequest setHTTPBody: requestData];
NSURLResponse *theResponse = NULL;
NSError *theError = NULL;
NSData *theResponseData = [NSURLConnection sendSynchronousRequest:theRequest returningResponse:&theResponse error:&theError];
NSString *data=[[NSString alloc]initWithData:theResponseData encoding:NSUTF8StringEncoding];
NSLog(#"url to send request= %#",url);
NSLog(#"response1111:-%#",data);
return data;
}
Both while using GET and POST We do not need to use setHTTPBody?
setHTTPBody only make sense when you are using POST request. GET don't need it.
For Header parameters do something like below
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:theURL cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:20.0f];
//Specify method of request(Get or Post)
[theRequest setHTTPMethod:#"GET"];
//Pass some default parameter(like content-type etc.)
[theRequest setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[theRequest setValue:#"application/json; charset=UTF-8" forHTTPHeaderField:#"Content-Type"];
//Now pass your own parameter
[theRequest setValue:yourObj forHTTPHeaderField:#"your parameter name"];
setHTTPBody is used when HTTP method POST is being used.
NSMutableURLRequest * request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:theUrl] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:120.0];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-type"];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setHTTPMethod:#"POST"];
[request setHTTPBody:data];
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
Here the data is nothing but NSData of JSON data that need's to be sent.

I have a string with webservice.But when i add the string into NSMutableRequest, The method return become null.Here is my code,
-(NSMutableURLRequest *)createRequest:(NSString *)convertedString{
NSString *temp=[NSString stringWithFormat:#"%#%#",Api_Link,convertedString];
NSLog(#"%#",temp);
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:temp]];
[request setHTTPBody:[convertedString dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES]];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setValue:#"App IPHONE" forHTTPHeaderField:#"USER_AGENT"];
[request setHTTPMethod:#"POST"];
return(request);
}
I ran your code in an Xcode Project:
NSString *temp = #"https://www.google.se/";
NSString *temsssp = #"https://www.google.se/";
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:temp]];
[request setHTTPBody:[temsssp dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES]];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setValue:#"App IPHONE" forHTTPHeaderField:#"USER_AGENT"];
[request setHTTPMethod:#"POST"];
NSLog(#"%#", request);
Result:
2017-02-15 06:43:23.061816 Sneak[5023:3002603] <NSMutableURLRequest: 0x170218120> { URL: https://www.google.se/ }
So there is nothing wrong with your request if you have a valid URL.
If you need further details and help, provide further information and code on how you run this method, and I will update the answer accordingly as your question changes or is edited.
EDIT:
As I mentioned, you need a Valid URL, I did the NSLog for you with this line:
NSString *temp = #"somethingsomething";
And the results are nil. So again, you need a valid URL.

Please help
I have to make json post request with the following request parameters,
{
"method":"login",
"data":{
"username":"korea",
"password":"123456"
}
}
I use the following code to make the request,
NSString *jsonRequest = [NSString stringWithFormat:#"{""\"\method:\"\login\"\"\,""\data:\"{\"\"username\":\"%#\",\"password\":\"%#\"}",username,password];
NSLog(#"Request: %#", jsonRequest);
NSURL *url = [NSURL URLWithString:#"http://myurl..."];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
NSData *requestData = [NSData dataWithBytes:[jsonRequest UTF8String] length:[jsonRequest length]];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request setValue:[NSString stringWithFormat:#"%d", [requestData length]] forHTTPHeaderField:#"Content-Length"];
[request setHTTPBody: requestData];
NSURLConnection *connection = [NSURLConnection connectionWithRequest:request delegate:self];
I have to get the response but Im not be able to get the response
Try this
NSDictionary *objectDic = #{#"username" : username, #"password" : password};
NSDictionary *dataDic = #{#"data" : objectDic};
NSDictionary *methodDic = #{#"method" : #"login", #"data": dataDic};
NSData *requestData = [NSJSONSerialization dataWithJSONObject:methodDic
options:NSJSONWritingPrettyPrinted
error:nil];
[request setHTTPBody: requestData];
In my application I need to make a PUT type request. I have followed the below steps
NSString *path = #"http://hostname/api/Account/VerifyUser?applicationToken=72B648C6-B2B7-45ED-BA23-2E8AAA187D2C&emailID=xxx#gmail.com&password=aaaaa";
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:
[NSURL URLWithString:path]];
[request setHTTPMethod:#"PUT"];
[request setValue:[NSString stringWithFormat:#"%d", string.length] forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded;charset=utf-8" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:[string dataUsingEncoding:NSUTF8StringEncoding]];
[[NSURLConnection alloc] initWithRequest:request delegate:self];
For POST and GET I am getting correct output.
I have searched a lot but i am not getting any solution.Please suggest me any possible solution .
Thanks in advance
Try this
For xml request body
Set [request setValue:#"application/x-www-form-urlencoded;charset=utf-8;application/form-data" forHTTPHeaderField:#"Content-Type"];
OR
For json request body
Set [request setValue:#"application/x-www-form-urlencoded;charset=utf-8;application/json" forHTTPHeaderField:#"Content-Type"];
http://novatoresols.com/demos/blow/users/add.json?json={"email":"ali"}
How can I send a key and data to web? Here "email" is the key and "ali" is the value in URL.
Code:
NSURL *url=[NSURL URLWithString:[hostURL stringByAppendingFormat:#"users/add.json?json="]];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
NSString * params =#"{\"email\":\"Ali\"}";
[request setHTTPMethod:#"POST"];
// This is how we set header fields
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:[params dataUsingEncoding:NSUTF8StringEncoding]];
connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
Simply Try with this :
NSString * params =#"{\"email\":\"Ali\"}";
NSURL *url=[NSURL URLWithString:[hostURL stringByAppendingFormat:#"users/add.json?json=%#",params]];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSLog (#"%#",data);
