How to print AFNetworking request as RAW data

Question

For debuging purposes I\'d want to print whole request body. I\'m using AFHTTPClient. printing client gives some information, like headers but post/get params are not there.

Answer 1

Built-in AFNetworking tools

For AFNetworking 1.x, use AFHTTPRequestOperationLogger.

For AFNetworking 2.x, use AFNetworkActivityLogger.

These tools both use the NSNotification broadcast by AFNetworking to log request and response data to the console. The amount of information to be displayed is configurable, and they can be configured to ignore certain operations.

Examination in Xcode without these tools

HTTP Requests (outgoing data)

If you want to examine the body of an outgoing request, look at the NSURLRequest's HTTPBody parameter, which is a property on your AFHTTPRequestOperation.

For example, in the method -[AFHTTPClient getPath: parameters: success: failure:], after the request is made, you can type this into the debugger:

po [[NSString alloc] initWithData:request.HTTPBody encoding:4]

_{4 is NSUTF8StringEncoding, as defined in NSString.h.}

The NSURLRequest's HTTPMethod parameter provides the method (GET, POST, PUT, etc.) as an NSString.

HTTP Responses (incoming data)

When your server responds, your success completion block is passed an AFHTTPRequestOperation object (called operation by default). You can:

• p (int)[[operation response] statusCode] to see the status code
• po [[operation response] allHeaderFields] to see the headers
• po [operation responseString] to see the response body
• po [operation responseObject] to see the response object (which may be nil if it couldn't be serialized)

Answer 2

For AFNetworking 3.0 to be able to set the level of logging, you need the following:

#import <AFNetworkActivityLogger/AFNetworkActivityLogger.h>
#import <AFNetworkActivityLogger/AFNetworkActivityConsoleLogger.h>

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    AFNetworkActivityConsoleLogger *logger = [AFNetworkActivityLogger sharedLogger].loggers.anyObject;
    logger.level = AFLoggerLevelDebug;
    [[AFNetworkActivityLogger sharedLogger] startLogging];

    return YES;
}

Answer 3

You should have a look at https://github.com/AFNetworking/AFHTTPRequestOperationLogger with AFLoggerLevelDebug as level of debugging.

#import "AFHTTPRequestOperationLogger.h"

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
#ifdef DEBUG
    [[AFHTTPRequestOperationLogger sharedLogger] startLogging];
    [[AFHTTPRequestOperationLogger sharedLogger] setLevel:AFLoggerLevelDebug];
#endif
    return YES;
}

@end

Answer 4

As of AFNetworking 2.0, you should use AFNetworkActivityLogger

#import "AFNetworkActivityLogger.h"

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
#ifdef DEBUG
    [[AFNetworkActivityLogger sharedLogger] startLogging];
    [[AFNetworkActivityLogger sharedLogger] setLevel:AFLoggerLevelDebug];
#endif
    return YES;
}

If you are using 3.0 and using CocoaPods, you will also need to pull AFNetworkActivityLogger from the appropriate branch:

pod 'AFNetworkActivityLogger', git: 'https://github.com/AFNetworking/AFNetworkActivityLogger.git', branch: '3_0_0'
