我使用这个代码的JSON发送到.NET服务注册用户:检索错误响应POST
NSDictionary *dictionary = [NSDictionary dictionaryWithObjectsAndKeys:
deviceID, @"DeviceId",
model, @"DeviceModel",
user, @"Username",
pass, @"Password",
email, @"email",
nil];
NSDictionary *consumer = [NSDictionary dictionaryWithObject:dictionary forKey:@"consumer"];
NSLog(@"%@", consumer);
NSError *error = nil;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:consumer
options:kNilOptions
error:&error];
NSLog(@"%@", error);
NSString *urlString = @"http://aservice.co.uk/services/service.svc/RegisterConsumer";
NSURL *url = [NSURL URLWithString:urlString];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/json; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:jsonData];
NSURLResponse *response = NULL;
NSError *requestError = NULL;
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&requestError];
NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding] ;
NSLog(@"%@", responseString);
NSLog(@"%@", requestError);
我领回{"RegisterConsumerResult":"True"}
现在,当我尝试注册一个用户名,我知道已经存在,我得到以下HTML作为responseString:

<div id="content">
<p class="heading1">Request Error</p>
<p>The server encountered an error processing the request. See server logs for more details.</p>

显然,这不是返回实际ERR或者,只是一个网页告诉我有一个错误。 错过了从服务中检索实际错误代码的方法吗? 服务是否有可能以某种方式作为响应发送错误?
编辑 - 我忘了提及,实际的errorResponse是零,我假设因为HTML被返回,实际的请求被归类为成功。
我想我们需要看你的asp.net代码。你如何处理你的服务器上的错误? – mkral
不幸的是我没有编写服务器代码。 – Darren
所以错误是由响应代码触发的。有关NSURLError的更多信息,请参阅此文档https://developer.apple.com/library/mac/#documentation/Cocoa/Reference/Foundation/Miscellaneous/Foundation_Constants/Reference/reference.html#//apple_ref/doc/constant_group/URL_Loading_System_Error_Codes – mkral
