将 rapidjson::Value 类型传递给另一个函数时出错

Question

我需要使用以下代码将 rapidjson::Value 类型的变量传递给另一个函数：

#include "filereadstream.h"
#include "stringbuffer.h"
#include "rapidjson.h"
#include "document.h"
#include <iostream>
#include <fstream>
#include <string>

using namespace rapidjson;
using namespace std;

static void processJsonValue(Value jsonValue) {

    if (jsonValue.IsArray() && !jsonValue.Empty()) {

        //jsonValue is valid
        //json value processing procedure below...

    }

}


void main()
{

    char* chartFile = "C:\Users\DrBlindriver\Documents\test.json";
    ifstream in(chartFile);
    //attempt to open json file
    if (!in.is_open()) {
        cout << "Failed to access json file!\n";
        return;
    }

    const string jsonContent((istreambuf_iterator<char>(in)), istreambuf_iterator<char>());
    in.close();

    Document jsonFile;
    //read json and check for error
    if ((jsonFile.Parse(jsonContent.c_str()).HasParseError()) || !(jsonFile.HasMember("testMember"))) {
        cout << "Invalid json file!\n";
        return;
    }

    Value testMember;
    //attempt to pass testMember value to processJsonValue 
    testMember = jsonFile["testMember"];

    processJsonValue(testMember);

}

当我遇到错误 E0330:

"rapidjson::GenericValue<Encoding, Allocator>::GenericValue(const rapidjson::GenericValue<Encoding, Allocator> &rhs) [with Encoding=rapidjson::UTF8, Allocator=rapidjson::MemoryPoolAllocatorrapidjson::CrtAllocator]" (declared at line 574 of "C:\Users\DrBlindriver\source\repos\RapidJsonTest\RapidJsonTest\json\document.h") is inaccessible

在

processJsonValue(testMember);

从来没有遇到过这样的错误，在网上找了很久的解决方法，但是没有用。请帮助或提供一些想法如何解决这个问题。

错误说

rapidjson::GenericValue<Encoding, Allocator>::GenericValue(const
rapidjson::GenericValue<Encoding, Allocator> &rhs) (...) is inaccessible

对我来说，这看起来像一个复制构造函数。如果在 processJsonValue(testMember) 处抛出错误，请尝试让您的 processJsonValue 函数通过引用获取参数：

static void processJsonValue(Value& jsonValue) {
   // code here
}
