AFNetworking 2.0始终返回403

afnetworking-2 json objective-c ios

roof · 技术社区 · 10 年前

我正在使用AFNetworking 2.0对JSON进行GET请求

    self.managerMasterFetchDeletes = [AFHTTPRequestOperationManager manager];
        self.managerMasterFetchDeletes.requestSerializer.timeoutInterval = 4.0f;
        self.managerMasterFetchDeletes.requestSerializer = [AFJSONRequestSerializer serializer];
        self.managerMasterFetchDeletes.responseSerializer = [AFJSONResponseSerializer serializer];

NSURL *URL = [NSURL URLWithString:rest];
    NSURLRequest *request = [NSURLRequest requestWithURL:URL];
    AFHTTPRequestOperation *op = [[AFHTTPRequestOperation alloc] initWithRequest:request];
    op.responseSerializer = [AFJSONResponseSerializer serializer];

    [op setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
        if (operation.response.statusCode==200){

            NSDictionary *dictionary   = (NSDictionary*)responseObject;
            NSMutableDictionary *responseData = [NSMutableDictionary new];
            if ([dictionary objectForKey:@"responseData"]) {
                responseData = [[dictionary objectForKey:@"responseData"] mutableCopy];
            }
            [responseData setValue:entity forKey:@"entityName"];
            [responseData setValue:[NSNumber numberWithInt:timeStamp] forKey:@"lastSync"];
            [[NSNotificationCenter defaultCenter]
             postNotificationName:notification
             object:nil userInfo:responseData];

        }
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"Error: %@", error);
    }];

 NSArray *operations = [AFURLConnectionOperation batchOfRequestOperations:[arrayOperations copy] progressBlock:^(NSUInteger numberOfFinishedOperations, NSUInteger totalNumberOfOperations) {
        NSLog(@"%lu of %lu fetch delete complete", numberOfFinishedOperations, totalNumberOfOperations);
    } completionBlock:^(NSArray *operations) {
        NSLog(@"All operations in batch complete");
        [[NSNotificationCenter defaultCenter]
         postNotificationName:@"MasterFecthDeleteEnd"
         object:nil
         userInfo:nil];
    }];

    [self.managerMasterFetchDeletes.operationQueue addOperations:operations waitUntilFinished:NO];

但它总是返回403,并返回以下错误:不可接受的内容类型:text/html

奇怪的是,我对Cocoa Graphical HttpClient所做的相同请求没有问题,并返回JSON响应,如下所示:

内容类型:application/json;字符集=UTF-8 日期:2015年9月25日星期五15:28:27 GMT 传输编码:标识 X-Powered-By:Servlet/2.5 JSP/2.1

非常感谢。

服务器似乎发送text/html ContentTypes。要接受此类型的内容,请添加text/html acceptableContentTypes .

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];
[manager GET:url parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {

} failure:^(AFHTTPRequestOperation *operation, NSError *error) {

}];

这意味着您的服务器正在发送 "text/html" 而不是已经支持的类型。我的解决方案是添加 “text/html” 到中设置的acceptableContentTypes AFURLResponseSerialization 班只需搜索“acceptableContentTypes”并添加 @"text/html" 手动设置。

op.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];

当然,理想的解决方案是更改从服务器发送的类型,但为此,您必须与服务器团队讨论。

你可以这样做。

NSURL *URL = [NSURL URLWithString:rest];
    NSURLRequest *request = [NSURLRequest requestWithURL:URL];
    AFHTTPRequestOperation *op = [[AFHTTPRequestOperation alloc] initWithRequest:request];
    op.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];

    [op setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
        if (operation.response.statusCode==200){

            NSDictionary *dictionary   = (NSDictionary*)responseObject;
            NSMutableDictionary *responseData = [NSMutableDictionary new];
            if ([dictionary objectForKey:@"responseData"]) {
                responseData = [[dictionary objectForKey:@"responseData"] mutableCopy];
            }
            [responseData setValue:entity forKey:@"entityName"];
            [responseData setValue:[NSNumber numberWithInt:timeStamp] forKey:@"lastSync"];
            [[NSNotificationCenter defaultCenter]
             postNotificationName:notification
             object:nil userInfo:responseData];

        }
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"Error: %@", error);
    }];
