I've been using AFNetworking 2.0 in my app. I've noticed that if my web-service returns a 500 status code I do not get the body of the response.
Here is an example of my php code
try
{
$conn = new PDO( "sqlsrv:server=$serverName;Database = $database", $uid, $pwd);
$conn->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
return $conn;
}
catch( PDOException $e )
{
$response->status(500);
echo( "Connection Error: " . $e->getMessage() );
}
If I use a simple rest client this is an example of a response body.
Connection Error: SQLSTATE[08001]: [Microsoft][SQL Server Native Client 11.0]SQL Server Network Interfaces: Error Locating Server/Instance Specified [xFFFFFFFF].
However this seems to be the only response I can get from AFNetworking
Error Domain=NSCocoaErrorDomain Code=3840 "The operation couldn’t be completed. (Cocoa error 3840.)" (JSON text did not start with array or object and option to allow fragments not set.) UserInfo=0x15e58fa0 {NSDebugDescription=JSON text did not start with array or object and option to allow fragments not set.}
This is the part of my objective-c code that does this.
...} failure:^(NSURLSessionDataTask *task, NSError *error) {
NSLog(@"%@",error.description);
}];
Is there a way I can get the response body?
Edit: More code for clarification
Below is part of my subclass of AFHTTPSessionManager
@implementation MSMAMobileAPIClient
+ (MSMAMobileAPIClient *)sharedClient {
static MSMAMobileAPIClient *_sharedClient = nil;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
_sharedClient = [[MSMAMobileAPIClient alloc] initWithDefaultURL];
});
return _sharedClient;
}
- (id)initWithDefaultURL {
return [self initWithBaseURL:[NSURL URLWithString:[NSString stringWithFormat:@"https://%@/mamobile/index.php/" ,[[NSUserDefaults standardUserDefaults] stringForKey:@"serviceIPAddress"]]]];
}
- (id)initWithBaseURL:(NSURL *)url {
self = [super initWithBaseURL:url];
if (!self) {
return nil;
}
self.responseSerializer = [AFCompoundResponseSerializer compoundSerializerWithResponseSerializers:@[[AFJSONResponseSerializer serializer], [AFHTTPResponseSerializer serializer]]];
return self;
}
I tried setting the response serializer to a AFCompoundResponseSerializer but it didn't seem to make a difference
Below is an example of a subclass that I call the Librarian.
-(void)searchForItemWithString:(NSString *)searchString withCompletionBlock:(arrayBlock)block {
self.inventorySearchBlock = block;
NSDictionary *parameters = @{@"query": searchString};
[[MSMAMobileAPIClient sharedClient] GET:@"inventory/search" parameters:parameters success:^(NSURLSessionDataTask *task, id responseObject) {
if (!responseObject) {
NSLog(@"Error parsing JSON");
} else {
//do stuff with the json dictionary that's returned..
}
} failure:^(NSURLSessionDataTask *task, NSError *error) {
NSLog(@"Error: %@",error.description);
}];
}
UPDATE: I have created a github repository to contain the latest code I am using. All changes will be posted there. https://github.com/Hackmodford/HMFJSONResponseSerializerWithData
The answer comes from this issue on github. https://github.com/AFNetworking/AFNetworking/issues/1397
gfiumara is the dev who came up with this. I have only slightly modified his subclass of AFJSONResponseSerializer to include an actual string instead of the NSData
//MSJSONResponseSerializerWithData.h
#import "AFURLResponseSerialization.h"
/// NSError userInfo key that will contain response data
static NSString * const JSONResponseSerializerWithDataKey = @"JSONResponseSerializerWithDataKey";
@interface MSJSONResponseSerializerWithData : AFJSONResponseSerializer
@end
// MSJSONResponseSerializerWithData.m
#import "MSJSONResponseSerializerWithData.h"
@implementation MSJSONResponseSerializerWithData
- (id)responseObjectForResponse:(NSURLResponse *)response
data:(NSData *)data
error:(NSError *__autoreleasing *)error
{
if (![self validateResponse:(NSHTTPURLResponse *)response data:data error:error]) {
if (*error != nil) {
NSMutableDictionary *userInfo = [(*error).userInfo mutableCopy];
userInfo[JSONResponseSerializerWithDataKey] = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSError *newError = [NSError errorWithDomain:(*error).domain code:(*error).code userInfo:userInfo];
(*error) = newError;
}
return (nil);
}
return ([super responseObjectForResponse:response data:data error:error]);
}
@end
Here is an example of how I use it in the failure block.
} failure:^(NSURLSessionDataTask *task, NSError *error) {
NSLog(@"%@",[error.userInfo objectForKey:@"JSONResponseSerializerWithDataKey"]);
}];
