我今天早些時候正在測試RapidJSON庫以查看我是否可以使用嵌套值解析文檔,出於某種原因,我無法想出解決方案的錯誤I越來越。我搜索了Google和Stack Overflow一兩個小時,但找不到修復程序。下面是與錯誤一起代碼:斷言`IsArray()'失敗(RapidJSON)
main.cpp中:
#include <iostream>
#include <SFML/Graphics.hpp>
#include "rapidjson/document.h"
#include "include.hpp"
int main() {
unsigned int input = 1;
tile output;
output = LoadTile("../locations.json", input);
std::cout << output.x << std::endl;
return 0;
}
load.cpp
#include <iostream>
#include "rapidjson/document.h"
#include "rapidjson/filereadstream.h"
#include "include.hpp"
using namespace rapidjson;
tile LoadTile(std::string fileName, unsigned int number) {
FILE* file = fopen(fileName.c_str(), "r");
char buffer[2048];
FileReadStream stream(file, buffer, 2048);
Document doc;
doc.ParseStream(stream);
tile output;
Value& tileNumber = doc[number];
if(!tileNumber.IsObject()) {
output.overflow = true;
output.x = 0;
output.y = 0;
output.type = "\0";
}else{
output.x = tileNumber[0]["x"].GetInt();
output.y = tileNumber[0]["y"].GetInt();
output.type = tileNumber[0]["type"].GetString();
}
return output;
}
include.hpp:
#include <iostream>
#include <SFML/Graphics.hpp>
#include "rapidjson/document.h"
struct tile {
int x;
int y;
std::string type;
bool overflow = false;
};
tile LoadTile(std::string fileName, unsigned int number);
的CMakeLists.txt:
cmake_minimum_required(VERSION 2.6)
project(test)
set(EXECUTABLE_NAME "test")
add_executable(${EXECUTABLE_NAME} main.cpp load.cpp include.hpp)
set(CMAKE_MODULE_PATH "${CMAKE_SOURCE_DIR}/cmake_modules" ${CMAKE_MODULE_PATH})
install(TARGETS ${EXECUTABLE_NAME} DESTINATION bin})
locations.json:
{
1:[
{"x":32},
{"y":32},
{"type":"water_c"}
]
}
錯誤:
test: /home/.../rapidjson/document.h:1547:rapidjson::GenericValue<Encoding, Allocator>::operator[](rapidjson::SizeType) [with Encoding = rapidjson::UTF8<>; Allocator = rapidjson::MemoryPoolAllocator<>; rapidjson::SizeType = unsigned int]: Assertion `IsArray()' failed.
Aborted (core dumped)
我知道這是不是JSON格式,我用盡了一切。除非有什麼確實錯了。我在Xubuntu 16.10上運行它。感謝任何能夠提供幫助的人。
