gsoap 超时（timeout）设置

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

gsoap就不用介绍了，是一个c/c++编写的可用于服务端与客户端的连接工具。

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后，然后就可以设置了。

在struct soap里面 是有很多参数的，具体可以参见  stdsoap2.h文件。。

只要

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

就可以。。

因为gsoap使用的包装http协议。然后最主要的是socket传输，对于我们熟悉的socket传输，我们在非阻塞的情况下才能设置超时。（包括 连接超时 accetp_timeout， 发送超时 send_timeout， 以及接受超时 recv_timeout）。

1.修改gsoap自动生成的代码才能进行超时设置(我这边访问web service的代码都是gsoap工具自动生成.根据wsdl接口)

 2.找到生成的soapwwwsdlBindingProxy.cpp文件

 3.找到你要设置超时的那个调用服务器的方法

 4.找到该方法代码   struct soap *soap = this;

      在该代码下添加如下三行代码(时间大小根据项目自行调整)
     soap->recv_timeout = 2;//接受  (单位是秒)
     soap->send_timeout = 2;//发送  (单位是秒)
     soap->connect_timeout = 2;//连接(单位是秒)
