上一篇文章已经粗略计划要讨论gsoap关于序列化/解析编程。
本文则阐述一下关于gsoap生成代码的一些重要特征方法及使用。如题,下我们从ONVIF生成的C码中,挑选简单的一个类型来试验一下与xsd__anyType之间的转换。这个试验如此重要,主要是因为,在之前我真的拿生成代码的相关结构的的一些__any字段没有办法。虽依据ONVIF文档,以及实际交互观测的XML结构中可知明明是已知的标准结构,却无奈生成被解析成any字段,主要是可能这部分字段可由厂商决定填充哪些扩展意义的结构。
本次试验选_trt__GetProfile结构作转换例程,主要理由是这个结构实在简单,只含有一个字段;书写初始化简单。
#soapStub.h
#ifndef SOAP_TYPE__trt__GetProfile #define SOAP_TYPE__trt__GetProfile (1365) /* trt:GetProfile */ struct _trt__GetProfile { char *ProfileToken; /* required element of type tt:ReferenceToken */ }; #endif
#include "inc.h" typedef struct soap *soap_pointer; #include "soap.nsmap" // anyType int anyType_ready(void) { return open("anyType.xml", O_RDWR|O_CREAT, S_IWUSR|S_IRUSR); } int FD_set(int* FD, int fd) { int ret = *FD; *FD = fd; return ret; }
注:inc.h是自组织的部分所需头依赖;
后面包含了soap.nsmap文件,你懂的,里面解开可以可以依次了解清楚包含与依赖关系;
soap.nsmap < soapH.h < soapStub.h < stdsoap2.h
static xsd__anyType* _trt__GetProfile2anyType(soap_pointer soap_, struct _trt__GetProfile* p_, xsd__anyType* _any); static struct _trt__GetProfile* _trt__GetProfile_from_anyType(soap_pointer soap_, struct _trt__GetProfile* _p, xsd__anyType* _any); int main(int argc, char const *argv[]) { /* code */ struct soap soap; soap_pointer soap_ = &soap; soap_init(soap_); struct _trt__GetProfile Data = {"Profile0"}; xsd__anyType Dom; soap_default_xsd__anyType(soap_, &Dom); if (_trt__GetProfile2anyType(soap_, &Data, &Dom)) { soap_default__trt__GetProfile(soap_, &Data); if (_trt__GetProfile_from_anyType(soap_, &Data, &Dom)) printf("Data >%s", Data.ProfileToken); } soap_end(soap_);soap_done(soap_); return 0; }
xsd__anyType* _trt__GetProfile2anyType( soap_pointer soap_, struct _trt__GetProfile* p_, xsd__anyType* _any ) { int fd = anyType_ready(); bool b = (fd == -1); if (b) return NULL; do { int* FD = &(soap_->sendfd); fd = FD_set(FD, fd); b = (soap_write__trt__GetProfile(soap_, p_) != SOAP_OK); fd = FD_set(FD, fd); b &= (lseek(fd, 0, SEEK_SET) == -1); if (b) break; FD = &(soap_->recvfd); fd = FD_set(FD, fd); b = (soap_read_xsd__anyType(soap_, _any) != SOAP_OK); fd = FD_set(FD, fd); } while(false); close(fd); if (b) return NULL; return _any; } struct _trt__GetProfile* _trt__GetProfile_from_anyType(soap_pointer soap_, struct _trt__GetProfile* _p, xsd__anyType* _any) { int fd = anyType_ready(); bool b = (fd == -1); if (b) return NULL; do { int* FD = &(soap_->sendfd); fd = FD_set(FD, fd); b = (soap_write_xsd__anyType(soap_, _any) != SOAP_OK); fd = FD_set(FD, fd); b &= (lseek(fd, 0, SEEK_SET) == -1); if (b) break; FD = &(soap_->recvfd); fd = FD_set(FD, fd); b = (soap_read__trt__GetProfile(soap_, _p) != SOAP_OK); fd = FD_set(FD, fd); } while(false); close(fd); if (b) return NULL; return _p; }
You can assign an output stream to soap.os or a le descriptor to soap.sendfd. For example
soap.sendfd = open(file, O_RDWR|O_CREAT, S_IWUSR|S_IRUSR); soap_serialize_PointerTons_Person(&soap, &p); soap_begin_send(&soap); soap_put_PointerTons_Person(&soap, &p, "ns:element-name", "ns:type-name"); soap_end_send(&soap);
The above can be abbreviated to
soap.sendfd = open(file, O_RDWR|O_CREAT, S_IWUSR|S_IRUSR); soap_write_PointerTons_Person(&soap, &p);
gSoap实现ONVIF中xsd__anyType到具体结构类的转换
