错误:__tcp_connection_write_eof_block_invoke 写入关闭回调收到错误 - iOS 10

Error: __tcp_connection_write_eof_block_invoke Write close callback received error - iOS 10(错误:__tcp_connection_write_eof_block_invoke 写入关闭回调收到错误 - iOS 10)

问题描述

向 ONVIF 摄像头发送 XML 基础 API 请求时.它在 ios 9 设备上运行良好，但在 iOS 10 上出现500 内部错误".

XCode 8 控制台打印以下错误消息:

2016-09-30 12:39:51.295419 VCPlugin[278:10183] [] nw_socket_get_input_frames recvmsg(fd 12, 1024 bytes): [54] Connection reset by peer2016-09-30 12:39:51.301221 VCPlugin[278:10228] [] nw_socket_write_close 关机(12，SHUT_WR):[57] 套接字未连接2016-09-30 12:39:51.301307 VCPlugin[278:10228] [] nw_endpoint_flow_service_writes [3 10.107.2.153:80 就绪套接字流(已满足)] 写入请求的帧数为 0，字节数为 02016-09-30 12:39:51.301903 VCPlugin[278:10185] [] __tcp_connection_write_eof_block_invoke 写入关闭回调收到错误:[89] 操作已取消2016-09-30 12:41:13.492053 VCPlugin[278:10287] [] __tcp_connection_write_eof_block_invoke 写入关闭回调收到错误:[57] 套接字未连接2016-09-30 12:42:51.278617 VCPlugin[278:10228] [] __tcp_connection_write_eof_block_invoke 写入关闭回调收到错误:[22] 无效参数

如果用户重试并重试三到四次，则在从服务器获得有效的 xml 响应之后.

我不知道 iOS 10 的这种行为.

这是我为调用 XML API 发布请求编写的代码:

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:%@ %@
", response, error);如果(错误 == 无){NSString * text = [[NSString alloc] initWithData: data1 encoding: NSUTF8StringEncoding];NSLog(@"数据 = %@",text);}}];[数据任务恢复]；

还阅读了

这将消除控制台中的消息.

但我仍然在努力解决 PLBuildVersion 在两者中都实现......

希望对你有帮助！

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:%@ %@
", 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.

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 !
