C语言实现gsoap输出数据类型到XML的方法

soap_out_TYPE,soap_put_TYPE

soap中输出数据都有两个函数soap_out_TYPE,soap_put_TYPE

    两个的区别是put只能输出一次，只能在一个函数中调用一次，out则可以调用多次，根据id的不同实现多个输出
实际上put的实现也是调用了out来实现的！
[cpp]
SOAP_FMAC3 int SOAP_FMAC4 soap_put_int(struct soap *soap, const int *a, const char *tag, const char *type)
{
    register int id = soap_embed(soap, (void*)a, NULL, 0, tag, SOAP_TYPE_int);
    if (soap_out_int(soap, tag?tag:"int", id, a, type))
        return soap->error;
    return soap_putindependent(soap);
}

SOAP_FMAC3 int SOAP_FMAC4 soap_put_int(struct soap *soap, const int *a, const char *tag, const char *type)
{
    register int id = soap_embed(soap, (void*)a, NULL, 0, tag, SOAP_TYPE_int);
    if (soap_out_int(soap, tag?tag:"int", id, a, type))
        return soap->error;
    return soap_putindependent(soap);
}

输出整型
[cpp]
int num=12345；
soap_put_int(soap, &num, "myint", NULL);

int num=12345；
soap_put_int(soap, &num, "myint", NULL);

页面会输出
[html]
?xml version="1.0" encoding="UTF-8"?>
<myint>12345</myint>

<?xml version="1.0" encoding="UTF-8"?>
<myint>12345</myint>

注意：在调用put_int函数时不需要先调用soap_serialize_int(soap, &num);
而在输出string或者结构体时需要先调用相关的 soap_serialize_type函数。

[cpp]
soap_out_int(soap,"myint",1,&num,NULL);
soap_out_int(soap,"myint",2,&num,NULL);

soap_out_int(soap,"myint",1,&num,NULL);
soap_out_int(soap,"myint",2,&num,NULL);

函数则会输出
[html]
<?xml version="1.0" encoding="UTF-8"?>
<myint id="_1" >12345</myint><myint id="_2" >12345</myint>

<?xml version="1.0" encoding="UTF-8"?>
<myint id="_1" >12345</myint><myint id="_2" >12345</myint>

函数在第一次调用out的时候会先把xml的头输出来，<?xml version="1.0" encoding="UTF-8"?>

输出字符串

[cpp]
char *str="hehe";
soap_serialize_string(soap, &str);
soap_put_string(soap, &str , "mystring", NULL);

char *str="hehe";
soap_serialize_string(soap, &str);
soap_put_string(soap, &str , "mystring", NULL);

页面会输出
[html]
<?xml version="1.0" encoding="UTF-8"?>
<mystring>hehe</mystring>

<?xml version="1.0" encoding="UTF-8"?>
<mystring>hehe</mystring>

使用soap_out_string(soap, &str , "mystring", NULL)函数的输出
[cpp]
soap_out_string(soap, "mystring",1,&str, NULL);
soap_out_string(soap, "mystring",2,&str, NULL);

soap_out_string(soap, "mystring",1,&str, NULL);
soap_out_string(soap, "mystring",2,&str, NULL);

页面会输出：
[html]
<?xml version="1.0" encoding="UTF-8"?>
<mystring id="_1">hehe</mystring><mystring id="_2">hehe</mystring>

<?xml version="1.0" encoding="UTF-8"?>
<mystring id="_1">hehe</mystring><mystring id="_2">hehe</mystring>

输出多个不同类型的参数(结构体)
在gsoap中想要输出多个不同类型的参数只能使用结构体的方法，
自定义一个结构体，在结构体中定义想要的输出的类型和参数，在当然必须在头文件中定义
然后用soapcpp2工具编译此头文件会生成相关的soap_out_TYPE,soap_put_TYPE,soap_serialize_TYPE等函数
实际上这几个函数的实现也是调用了相关类型的函数实现的，比如结构体中包含字符串，那么soap_serialize_TYPE就会调用soap_serialize_string函数实现

如下代码
[cpp]
struct LogInfo loginfo={"哈哈",1};
soap_serialize_LogInfo(soap,&loginfo)
soap_put_LogInfo(soap, &loginfo, "logs", NULL);

struct LogInfo loginfo={"哈哈",1};
soap_serialize_LogInfo(soap,&loginfo)
soap_put_LogInfo(soap, &loginfo, "logs", NULL);

页面会输出：
[html]
?xml version="1.0" encoding="UTF-8"?>
<logs>
<content>hehe</content>
<id>1</id>
</logs>

<?xml version="1.0" encoding="UTF-8"?>
<logs>
<content>hehe</content>
<id>1</id>
</logs>

多次调用soap_out_LogInfo函数
[cpp]
soap_serialize_LogInfo(soap,&loginfo)
soap_out_LogInfo(soap, "logs",1, &loginfo, NULL);
soap_out_LogInfo(soap, "logs",2, &loginfo, NULL);

soap_serialize_LogInfo(soap,&loginfo)
soap_out_LogInfo(soap, "logs",1, &loginfo, NULL);
soap_out_LogInfo(soap, "logs",2, &loginfo, NULL);

页面会输出
[html]
<?xml version="1.0" encoding="UTF-8"?>
<logs id="_1">
    <content>hehe</content>
    <id>1</id>
</logs>
<logs id="_2">
    <content>hehe</content>
    <id>1</id>
</logs>

<?xml version="1.0" encoding="UTF-8"?>
<logs id="_1">
    <content>hehe</content>
    <id>1</id>
</logs>
<logs id="_2">
    <content>hehe</content>
    <id>1</id>
</logs>
