我构建了如下消息：
MESSAGE soapMSG;
HEADER soapHeader;
BODY soapBody;
LANE soapLane;
...
soapMSG.BODY_ = std::make_shared<BODY>(); // here i use a maping pointer to sharedptr
soapMSG.BODY_->_BODY = new ((_union_BODY *)soap_malloc(ctx, 2 * sizeof(_unionBody))) _union_BODY[2];
soapMSG.BODY_->__size_BODY = 2;
soapMSG.BODY_->_BODY[0].__union_BODY = SOAP_UNION_union_BODY_LANE_;
soapMSG.BODY_->_BODY[0]._BODY.LANE_ = &soapLane;
...
问题是： 当xsd包含xs：choice时，gsoap会生成一个通过动态数组使用的联合，问题是每个_union_Body gsoap都会使用包含的父元素呈现它
<MESSAGE xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" VERSION="0">

我该如何避免这种情况？
提前谢谢!!
答案 0 :(得分：0)
我找到了解决方案： 来自Genivia Doc “ 成员成为隐藏的XML元素，即当其名称以双下划线开头时，不会以XML格式呈现。这使得对数据成员集合进行排序成为可能，基本上通过形成一系列可以选择或重复的元素。“ 然后我修改了gsoap从
生成的.h/// @brief Top-level root element "":BODY
/// @brief "":BODY is a complexType.
///
/// class BODY operations:
/// - BODY* soap_new_BODY(soap*) allocate and default initialize
/// - BODY* soap_new_BODY(soap*, int num) allocate array and default initialize values
/// - BODY* soap_new_req_BODY(soap*, ...) allocate, set required members
/// - BODY* soap_new_set_BODY(soap*, ...) allocate, set all public members
/// - BODY::soap_default(soap*) default initialize members
/// - int soap_read_BODY(soap*, BODY*) deserialize from a stream
/// - int soap_write_BODY(soap*, BODY*) serialize to a stream
/// - BODY* BODY::soap_dup(soap*) returns deep copy of BODY, copies the (cyclic) graph structure when a context is provided, or (cycle-pruned) tree structure with soap_set_mode(soap, SOAP_XML_TREE) (use soapcpp2 -Ec)
/// - BODY::soap_del() deep deletes BODY data members, use only after BODY::soap_dup(NULL) (use soapcpp2 -Ed)
class BODY
{ public:
// BEGIN CHOICE <xs:choice maxOccurs="2">
$int __size_BODY 0:2;
class ___union_BODY
{
$int __union_BODY ; ///< Union union_BODY selector: set to SOAP_UNION_union_BODY_<fieldname>

union union_BODY
{

};
为：
let arr1 = [
{ id: "abdc4051", date: "2017-01-24" },
{ id: "abdc4052", date: "2017-01-22" }
];
let arr2 = [
{ id: "abdc4051", name: "ab" },
{ id: "abdc4052", name: "abc" }
];
let arr3 = [];
arr1.forEach((itm, i) => {
arr3.push(Object.assign({}, itm, arr2[i]));
});
console.log(arr3);请注意我已将类_unionody_BODY重命名为___unión_BODY，并将变量名_BODY重命名为___ BODY
非常感谢你。
