错误：__ tcp_connection_write_eof_block_invoke写入关闭回调收到错误 - iOS 10 [英] Error: __tcp_connection_write_eof_block_invoke Write close callback received error - iOS 10

问题描述

向ONVIF Camera发送XML基本API请求时。它在ios 9设备上工作正常，但在iOS 10上提供500内部错误。

XCode 8控制台打印出错误消息：

  2016-09-30 12：39：51.295419 VCPlugin [278：10183] [] nw_socket_get_input_frames recvmsg（fd 12,1024字节）：[54]连接重置为同行

如果用户重试并重试三到一四次，然后从服务器获得有效的xml响应。

我不知道这个iOS 10的行为。

<这是我为调用XML API post请求编写的代码：

  NSMutableURLRequest * urlRequest = [NSMutableURLRequest requestWithURL：url]; 
 [urlRequest setHTTPMethod：@POST]; 
 [urlRequest setHTTPBody：body]; 
 [urlRequest setValue：@application / soap + xmlforHTTPHeaderField：@Content-Type]; 
 [urlRequest setValue：@application / soap + xmlforHTTPHeaderField：@Accept]; 
 
 NSURLSessionDataTask * dataTask = [defaultSession dataTaskWithRequest：urlRequest completionHandler：^（NSData * data1，NSURLResponse * response，NSError * error）{
 NSLog（@Response：％@％@ \ n，响应，错误）; 
 if（error == nil）
 {
 NSString * text = [[NSString alloc] initWithData：data1 encoding：NSUTF8StringEncoding]; 
 NSLog（@Data =％@，text）; 
} 
}]; 
 
 [dataTask resume]; 
  

同时阅读

这将消除控制台中的消息。

但是我仍然很难用 PLBuildVersion 在两个实现....

我希望这可以帮到你！

While sending XML base API Request to ONVIF Camera. It worked fine on ios 9 device, but giving '500 Internal Error' on iOS 10.

XCode 8 Console prints below error messages:

2016-09-30 12:39:51.295419 VCPlugin[278:10183] [] nw_socket_get_input_frames recvmsg(fd 12, 1024 bytes): [54] Connection reset by peer

If user retry and retry three-to-four times, then after get valid xml response from server.

I don't know this iOS 10 behaviour.

this is code i have written for call XML API post request:

NSMutableURLRequest * urlRequest = [NSMutableURLRequest requestWithURL:url];
[urlRequest setHTTPMethod:@"POST"];
[urlRequest setHTTPBody:body];
[urlRequest setValue: @"application/soap+xml" forHTTPHeaderField:@"Content-Type"];
[urlRequest setValue: @"application/soap+xml" forHTTPHeaderField:@"Accept"];

NSURLSessionDataTask * dataTask = [defaultSession dataTaskWithRequest:urlRequest completionHandler:^(NSData *data1, NSURLResponse *response, NSError *error) {
        NSLog(@"Response:%@ %@\n", response, error);
        if(error == nil)
        {
             NSString * text = [[NSString alloc] initWithData: data1 encoding: NSUTF8StringEncoding];
              NSLog(@"Data = %@",text);
        }
}];

[dataTask resume];

Also read Apple Form, but not get solution.

解决方案

try this code:

I have the same issue, but there is something you can do to,

1) Go in Product -> Scheme -> Edit Scheme
2) Run Section on the left, select Argument Tab and in Environment Variable put this.

OS_ACTIVITY_MODE to value : disable.

For more information please find the below screenshot.

This will get rid of messages in the console.

But I still struggle with the PLBuildVersion is implemented in both....

I hope this helps you !
