今天写了一个快递查询的功能，使用的是AFNetWorking框架，
贴个代码：
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0), ^{ NSDictionary *dict=@{@"key": @"key",@"com": @"shentong",@"cno": @"768938779991"}; NSString* encodedString = [@"http://api.kuaidiwo.cn:88/api/" stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; [appdelegate.manager POST:encodedString parameters:dict success:^(AFHTTPRequestOperation *operation, id responseObject) { NSLog(@"%@",responseObject); } failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"%@",error); }]; });
红色的是请求链接，好了，按说是没问题（但是如果别人写后台不规范，明明传回来的是json，但是写后台那个鸟非要写：
response.setContentType("text/html"); response.getWriter().write(json)） 把返回的内容类型写成"text/html",因为 AFNetWorking框架是解析不了这种类型的，所以就会报错，这时候抱怨那老鸟是没用的，难道你想拿板砖拍他么～还是好好改你的代码吧！
如果规范写，应该这样写：
For JSON:
Content-Type: application/json
response.setContentType(application/json");For JSON-P:
Content-Type: application/javascript请参考：
http://stackoverflow.com/questions/477816/what-is-the-correct-json-content-type
所以，我们必须要设置我们的解析器：
self.manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];
加上这句话，
这时候运行，如果你的请求方式是post，那我就呵呵了，我也是这样，后来报错，苦逼～
错误代码：
2014-10-14 22:43:32.953 测试快递[5208:60b] Error Domain=NSCocoaErrorDomain Code=3840 "The operation couldn’t be completed. (Cocoa error 3840.)" (JSON text did not start with array or object and option to allow fragments not set.) UserInfo=0x8c9a410 {NSDebugDescription=JSON text did not start with array or object and option to allow fragments not set.}
原谅我英语那么差，我也不知道问题错哪了，调了一下午，无意间把post改称get，那么问题来了，到底对不对呢？恭喜自己，真的对了～
