Content-Type为x-www-form-urlencod

最近在调试接口是遇到了Content-Type为application/x-www-form-urlencoded的网络请求，本来想着用封装好的AFN就可以实现了，结果总是request timeout，十分无奈，经过和服务器小伙伴进行一番调试，决定暂时放弃AFN，转用系统的网络请求方法，废话不多说，直接上干货

//url处理

NSString *url = @"www.baidu.com";

NSURL *Url = [NSURL URLWithString:url];

//参数拼接

NSMutableData *postBody=[NSMutableData data];

[postBody appendData:[[NSString stringWithFormat:@"key1=%@&key2&……",value1,value2,……] dataUsingEncoding:NSUTF8StringEncoding]];

//创建请求

NSMutableURLRequest *request=[[NSMutableURLRequest alloc]initWithURL:Url

cachePolicy:NSURLRequestReloadIgnoringCacheData

timeoutInterval:15.0f];

[request setHTTPMethod: @"POST"];

//设置Content-Type

[request setValue: @"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];

[request setHTTPBody:postBody];

NSOperationQueue *queue = [[NSOperationQueue alloc] init];

//异步请求网络

[NSURLConnection sendAsynchronousRequest:request queue:queue completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {

//数据处理

NSString *results = [[NSString alloc] initWithData:data

encoding:NSUTF8StringEncoding];

//        NSLog(@"结果：%@",results);

NSDictionary *resultDic = [self dictionaryWithJsonString:results];

//        NSLog(@"结果：%@，获取的字典数据 = %@",results,resultDic);

}];

好了，上面就是关键代码，有空了研究下AFN的x-www-form-urlencoded实现。
