Looking for an example of how to post json with AFHTTPClient
. I see that there is a postPath method which takes an NSDictionary
and the AFJSONEncode me
The best and simple way to do that is to subclass AFHTTPClient.
Use this code snippet
MBHTTPClient
#define YOUR_BASE_PATH @"http://sample.com"
#define YOUR_URL @"post.json"
#define ERROR_DOMAIN @"com.sample.url.error"
/**************************************************************************************************/
#pragma mark - Life and Birth
+ (id)sharedHTTPClient
{
static dispatch_once_t pred = 0;
__strong static id __httpClient = nil;
dispatch_once(&pred, ^{
__httpClient = [[self alloc] initWithBaseURL:[NSURL URLWithString:YOUR_BASE_PATH]];
[__httpClient setParameterEncoding:AFJSONParameterEncoding];
[__httpClient registerHTTPOperationClass:[AFJSONRequestOperation class]];
//[__httpClient setAuthorizationHeaderWithUsername:@"" password:@""];
});
return __httpClient;
}
/**************************************************************************************************/
#pragma mark - Custom requests
- (void) post<#Objects#>:(NSArray*)objects
success:(void (^)(AFHTTPRequestOperation *request, NSArray *objects))success
failure:(void (^)(AFHTTPRequestOperation *request, NSError *error))failure
{
[self postPath:YOUR_URL
parameters:objects
success:^(AFHTTPRequestOperation *request, id JSON){
NSLog(@"getPath request: %@", request.request.URL);
if(JSON && [JSON isKindOfClass:[NSArray class]])
{
if(success) {
success(request,objects);
}
}
else {
NSError *error = [NSError errorWithDomain:ERROR_DOMAIN code:1 userInfo:nil];
if(failure) {
failure(request,error);
}
}
}
failure:failure];
}
Then in your code just call
[[MBHTTPClient sharedHTTPClient] post<#Objects#>:objects
success:^(AFHTTPRequestOperation *request, NSArray *objects) {
NSLog("OK");
}
failure:(AFHTTPRequestOperation *request, NSError *error){
NSLog("NOK %@",error);
}
objects is an NSArray (you can change it to NSDictonary) and will be encode in JSON format
If you're posting to a JSON REST API, there should be a particular mapping from object property to JSON key, right? That is, the server is expecting certain information in certain named fields.
So what you want to do is construct an NSDictionary
or NSMutableDictionary
with the keys used in the API and their corresponding values. Then, simply pass that dictionary into the parameters
argument of any request method in AFHTTPClient
. If the parameterEncoding
property of the client is set to AFJSONParameterEncoding
, then the body of the requests will automatically be encoded as JSON.
- (NSMutableURLRequest *)requestByPostWithNSArrayToJSONArray:(NSArray *)parameters
{
NSURL *url = [NSURL URLWithString:@"" relativeToURL:self.baseURL];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
[request setHTTPMethod:@"POST"];
[request setAllHTTPHeaderFields:self.defaultHeaders];
if (parameters)
{
NSString *charset = (__bridge NSString *)CFStringConvertEncodingToIANACharSetName(CFStringConvertNSStringEncodingToEncoding(self.stringEncoding));
NSError *error = nil;
[request setValue:[NSString stringWithFormat:@"application/json; charset=%@", charset] forHTTPHeaderField:@"Content-Type"];
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wassign-enum"
[request setHTTPBody:[NSJSONSerialization dataWithJSONObject:parameters options:0 error:&error]];
#pragma clang diagnostic pop
if (error) {
NSLog(@"%@ %@: %@", [self class], NSStringFromSelector(_cmd), error);
}
}
return request;
}
AFHTTPClient *httpClient = [[AFHTTPClient alloc]initWithBaseURL:[NSURL URLWithString:URL_REGISTER_DEVICE]];
NSArray *array = @[@"hello", @"world"];
NSMutableURLRequest *request = [httpClient requestByPostWithNSArrayToJSONArray:array];
AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON)
{
NSLog(@"network operation succ");
} failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {
NSLog(@"network operation fail");
}];
[operation start];
