NSURLConnection GET请求返回-1005，“网络连接丢失” [英] NSURLConnection GET request returns -1005, "the network connection was lost"

问题描述

我试图在iOS 8 SDK的XCode 6（Beta7 2）中使用 NSURLConnection 做一个简单的GET请求，这是失败的代码1005，网络连接丢失了。当我尝试从网络中抓取 http://www.google.com 或其他几个示例页面时，调用失败，但如果成功我向localhost（ python -m SimpleHTTPServer ）上的简单HTTP服务器发出请求。我也尝试使用 AFNetworking 库（2.4.1） - 与NSURLConnection失败的URL也失败与库。

这是我的代码 -

  NSString * url = @http ：//0.0.0.0：8000; 
 // NSString * url = @http://www.google.com; 
 
 NSLog（@URL：％@，url）; 
 
 //可能不需要Mutable，但是为了防止它真正需要设置HTTP方法
 NSMutableURLRequest * theRequest = [NSMutableURLRequest requestWithURL：[NSURL URLWithString：url]]; 
 [theRequest setHTTPMethod：@GET]; 
 
 NSURLResponse * urlResponse = nil; 
 NSError * error = nil; 
 
 NSData * data = [NSURLConnection sendSynchronousRequest：theRequest 
 returningResponse：& urlResponse 
 error：& error]; 
 
 if（error == nil）{
 NSString * response = [[NSString alloc] initWithData：data encoding：NSASCIIStringEncoding]; 
 NSLog（response）; 
} else {
 NSString * response = [[NSString alloc] initWithData：data encoding：NSASCIIStringEncoding]; 
 NSLog（@％@，[error userInfo]）; 
}

解决方案

我最近在iPhone 6模拟器上看到互联网连接失败，导致相同的错误。我的Mac有一个工作的互联网连接模拟器没有。重新启动模拟器固定问题。

I am trying to make a simple GET request using NSURLConnection in XCode 6 (Beta7 2) on iOS 8 SDK, which is failing with "Code 1005, the network connection was lost". The call fails when I try to fetch http://www.google.com or a few other sample pages from the web, but succeeds if I make a request to a simple HTTP server on localhost (python -m SimpleHTTPServer). I have also tried using AFNetworking library (2.4.1) - URLs that fail with NSURLConnection also fail with the library.

Here's my code -

NSString * url = @"http://0.0.0.0:8000";
// NSString * url = @"http://www.google.com";

NSLog(@"URL : %@", url);

// Mutable is probably not required, but just in case it REALLY WANTS me to set HTTP method
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:url]];
[theRequest setHTTPMethod:@"GET"];

NSURLResponse *urlResponse = nil;
NSError *error = nil;

NSData * data = [NSURLConnection sendSynchronousRequest:theRequest
                                      returningResponse:&urlResponse
                                error:&error];

if (error == nil) {
    NSString *response = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];
    NSLog(response);
} else {
    NSString *response = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];
    NSLog(@"%@", [error userInfo]);
}

解决方案

I have seen internet connectivity failing on the iPhone 6 simulator recently, resulting in the same errors. My Mac had a working internet connection the simulator did not. Restarting the simulator fixed the issue.
