AFNetworking 3.x 迁移和 XML 解析器

Question

你好我要将使用 AFNetworking 1.2.1 和 AFRaptureXMLOperation 的旧项目升级到 AFNetworking 3.1 以满足 Apple 对 ipv6 的要求。但是因为 AFRaptureXMLOperation 不支持 AFNetworking 3.1 有没有转换和解析 JSON, XML？非常感谢任何帮助。谢谢！

我的一些 ApiClient.m 解析 Json 和 XML

#pragma mark - API calls

#pragma mark - Informations

- (void)getSingpostContentsOnSuccess:(ApiClientSuccess)success onFailure:(ApiClientFailure)failure {
    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"singpost-contents.php"
                                                                              relativeToURL:[NSURL URLWithString:CMS_BASE_URL]]];
    AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
        if (success)
            success(JSON);
    } failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {
        if (failure)
            failure(error);
        [self reportAPIIssueURL:[request.URL absoluteString] payload:nil message:[error description]];
    }];
    [self enqueueHTTPRequestOperation:operation];
}

对于 xml:

                                         onFailure:(ApiClientFailure)failure {
    NSString *xml = [NSString stringWithFormat:@"<SingaporePostalInfoDetailsRequest xmlns=\"http://singpost.com/paw/ns\">"
                     "<ToPostalCode>%@</ToPostalCode>"

                     "<Weight>%@</Weight>"
                     "<DeliveryServiceName></DeliveryServiceName>"
                     "</SingaporePostalInfoDetailsRequest>", toPostalCode, fromPostalCode, weightInGrams];

    NSMutableURLRequest *request = [self requestWithMethod:@"POST" path:@"ma/FilterSingaporePostalInfo" parameters:nil];
    [request addValue:@"application/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
    [request addValue:[NSString stringWithFormat:@"%ld", [xml length]] forHTTPHeaderField:@"Content-Length"];
    [request setHTTPBody:[xml dataUsingEncoding:NSUTF8StringEncoding]];

    AFRaptureXMLRequestOperation *operation = [AFRaptureXMLRequestOperation XMLParserRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, RXMLElement *XMLElement) {
        if (success)
            success(XMLElement);
    } failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, RXMLElement *XMLElement) {
        if (failure)
            failure(error);
        [self reportAPIIssueURL:[request.URL absoluteString] payload:xml message:[error description]];
    }];

    [self enqueueHTTPRequestOperation:operation];
}

我建议使用 TABXML 进行 XML 解析，因为它更快。这是 api github link TBXML Parser

这是我用 TBXML 解析器获取 xml 数据的函数，它可以帮助您了解更多信息。你只需要导入

#import "TBXML+HTTP.h"
#import "TBXML.h"


-(void)loadnews:(TBXMLElement *)element{

    TBXMLElement *item = [TBXML childElementNamed:@"item" parentElement:element];

    do {
        TBXMLElement *titre = [TBXML childElementNamed:@"title" parentElement:item];
        TBXMLElement *desc = [TBXML childElementNamed:@"description" parentElement:item];





        TBXMLElement *imgitem = [TBXML childElementNamed:@"enclosure" parentElement:item];


        News *myitem=[[News alloc] init];
        myitem.titre=[TBXML textForElement:titre];
        myitem.desc=[TBXML textForElement:desc];


        if(imgitem){
            myitem.img=[TBXML valueOfAttributeNamed:@"url" forElement:imgitem];

        }
        else {
            myitem.img=@"noimg";

        }












        [self.mytabnews addObject:myitem];



    } while ((item = item->nextSibling));

    //[self.tablenews performSelectorOnMainThread:@selector(reloadData)
    //      withObject:nil
    //  waitUntilDone:NO];}

    dispatch_async(dispatch_get_main_queue(), ^{
        [self.tablenews reloadData];
    });
}

对于 Json 使用 AFnetworking 3.x 解析，此功能可以帮助您：

   -(void) loadevents{

        NSString *path = @"yourapilinkhere";
        NSString *escapedPath = [path stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];

        AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];



[manager GET:escapedPath parameters:nil progress:nil success:^(NSURLSessionTask *task, id responseObject) {
            //NSLog(@"JSON: %@", responseObject);
    }];
