gsoap 超時（timeout）設置

參考：http://www.cs.fsu.edu/~engelen/soapdoc2.html#tth_sEc19.19

gsoap就不用介紹了，是一個c/c++編寫的可用於服務端與客戶端的鏈接工具。

 

Socket connect, accept, send, and receive timeout values can be set to manage socket communication timeouts. The soap.connect_timeout, soap.accept_timeout, soap.send_timeout, and soap.recv_timeout attributes of the current gSOAP runtime context soap can be set to the appropriate user-defined socket send, receive, and accept timeout values. A positive value measures the timeout in seconds. A negative timeout value measures the timeout in microseconds (10−6 sec).   The soap.connect_timeout specifies the timeout for soap_call_ns__method calls.   The soap.accept_timeout specifies the timeout for soap_accept(&soap) calls.   The soap.send_timeout and soap.recv_timeout specify the timeout for non-blocking socket I/O operations.   Example:  struct soap soap;  soap_init(&soap);  soap.send_timeout = 10;  soap.recv_timeout = 10; This will result in a timeout if no data can be send in 10 seconds and no data is received within 10 seconds after initiating a send or receive operation over the socket. A value of zero disables timeout, for example:  soap.send_timeout = 0;  soap.recv_timeout = 0; When a timeout occurs in send/receive operations, a SOAP_EOF exception will be raised ("end of file or no input"). Negative timeout values measure timeouts in microseconds, for example:  #define uSec *-1  #define mSec *-1000  soap.accept_timeout = 10 uSec;  soap.send_timeout = 20 mSec;  soap.recv_timeout = 20 mSec; The macros improve readability.   Caution: many Linux versions do not support non-blocking connect(). Therefore, setting soap.connect_timeout for non-blocking soap_call_ns__method calls may not work under Linux.   Caution: interrupts (EINTR) can affect the blocking time in I/O operations. The maximum number of EINTR that will not trigger an error is set by SOAP_MAXEINTR in stdsoap2.h, which is 10 by default. Each EINTR may increase the blocking time by up to one second, up to SOAP_MAXEINTR seconds total.

 

初始化gsoap後，而後就能夠設置了。

 

在struct soap裏面 是有不少參數的，具體能夠參見  stdsoap2.h文件。。

只要

soap.send_timeout = 10; 
soap.recv_timeout = 10;

就能夠。。

 

由於gsoap使用的包裝http協議。而後最主要的是socket傳輸，對於咱們熟悉的socket傳輸，咱們在非阻塞的狀況下才能設置超時。（包括 鏈接超時 accetp_timeout， 發送超時 send_timeout， 以及接受超時 recv_timeout）
