POST请求与JSON正文AFNetworking 2.0

无论如何，使用AFNetworking〜> 2.0发送带有JSON主体的POST请求？

我曾尝试使用：
manager.requestSerializer = [AFJSONRequestSerializer serializer]; manager POST:<url> parameters: @{@"data":@"value"} success: <block> failure: <block>'

但它不起作用。 任何帮助是极大的赞赏。 谢谢

你可以添加你的JSON正文在NSMutableURLRequest不直接parameters: 。 看我的示例代码：

 NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url]; // Set post method [request setHTTPMethod:@"POST"]; // Set header to accept JSON request [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"]; // Your params NSDictionary *params = @{@"data":@"value"}; // Change your 'params' dictionary to JSON string to set it into HTTP // body. Dictionary type will be not understanding by request. NSString *jsonString = [self getJSONStringWithDictionary:params]; // And finally, add it to HTTP body and job done. [request setHTTPBody:[jsonString dataUsingEncoding:NSUTF8StringEncoding]]; AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; manager.requestSerializer = [AFJSONRequestSerializer serializer]; AFHTTPRequestOperation *operation = [manager HTTPRequestOperationWithRequest:request success:<block> failure:<block>]; 

希望这会帮助你。 快乐的编码！ 🙂

如果有人在寻找AFNetworking 3.0，这里是代码

 NSError *writeError = nil; NSData* jsonData = [NSJSONSerialization dataWithJSONObject:params options:NSJSONWritingPrettyPrinted error:&writeError]; NSString* jsonString = [[NSString alloc]initWithData:jsonData encoding:NSUTF8StringEncoding]; NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:url] cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:120]; [request setHTTPMethod:@"POST"]; [request setValue: @"application/json; encoding=utf-8" forHTTPHeaderField:@"Content-Type"]; [request setValue: @"application/json" forHTTPHeaderField:@"Accept"]; [request setHTTPBody: [jsonString dataUsingEncoding:NSUTF8StringEncoding]]; AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]]; [[manager dataTaskWithRequest:request uploadProgress:nil downloadProgress:nil completionHandler:^(NSURLResponse * _Nonnull response, id _Nullable responseObject, NSError * _Nullable error) { if (!error) { NSLog(@"Reply JSON: %@", responseObject); if ([responseObject isKindOfClass:[NSDictionary class]]) { //blah blah } } else { NSLog(@"Error: %@", error); NSLog(@"Response: %@",response); NSLog(@"Response Object: %@",responseObject); } }] resume];
