Write yyjson issue

[zhoufei1]

Hi ibireme Thank you very much for your last reply, but I found a problem, please help me to solve it, and I look forward to your reply

//How to find yyjson_mut_val according to key yyjson_mut_val getOrCreateChildMutObj(yyjson_mut_doc doc, yyjson_mut_val parent, const std::string &key) { yyjson_mut_val child = yyjson_mut_get_pointer(parent, key.data()); if (!child)// if not find, build key/value { child = yyjson_mut_obj(doc); yyjson_mut_obj_add_val(doc, parent, key.data(), child); } return child; } //How to find array nodes(yyjson_mut_val) based on key ? yyjson_mut_val getOrCreateArray(yyjson_mut_doc doc, yyjson_mut_val arryParent, const std::string &key) { yyjson_mut_val arry = yyjson_mut_get_pointer(arryParent, key.data()); if (!arry) { arry = yyjson_mut_arr(doc); yyjson_mut_obj_add_val(doc, arryParent, key.data(), arry); } return arry; }

void funcLayout(yyjson_mut_doc *doc) { std::string key1("PATH_KEY_NODE"); std::string key2("INFO_KEY_NODE");

//case 1 { // auto val = getOrCreateChildMutObj(doc, doc->root, key1); // yyjson_mut_val layoutKeyNode = getOrCreateChildMutObj(doc, doc->root, key2); //output: It seems something went wrong / { "???\"m�\u0000\u0000?K\u0001\u0000": {}, "INFO_KEY?????�": {} } */ }

//case 2 { yyjson_mut_val* child = yyjson_mut_get_pointer(doc->root, key1.data()); if (!child) { child = yyjson_mut_obj(doc); yyjson_mut_obj_add_val(doc, doc->root, key1.data(), child); }

yyjson_mut_val* child1 = yyjson_mut_get_pointer(doc->root, key2.data());
if (!child1)
{
    child1 = yyjson_mut_obj(doc);
    yyjson_mut_obj_add_val(doc, doc->root, key2.data(), child1);
}

//output: Should be correct
/*
    {
        "PATH_KEY_NODE": {},
        "INFO_KEY_NODE": {}
    }
*/

}

}

void writeJson() { yyjson_mut_doc *doc = yyjson_mut_doc_new(nullptr); yyjson_mut_doc_set_root(doc, yyjson_mut_obj(doc));

funcLayout(doc); //funcVerify(doc);

yyjson_write_flag flg = YYJSON_WRITE_PRETTY /| YYJSON_WRITE_ESCAPE_UNICODE/; yyjson_write_err err; yyjson_mut_write_file("config.json", doc, flg, nullptr, &err);

yyjson_mut_doc_free(doc);

}

//////////////// Use yyjson in qt : 1、The result of this use is wrong ： int main(int argc, char *argv[]) { QApplication a(argc, argv); MainWindow w; w.show();

writeJson();  //////////////////////////

return a.exec();

}

2、The result of calling at the very beginning of the program is correct int main(int argc, char *argv[]) {

 writeJson(); //The result of calling at the very beginning of the program is correct 

QApplication a(argc, argv);
MainWindow w;
w.show();

return a.exec();

}

////////////////////////////////// The output result of my case 2 method should be correct, but the output result of case 1 seems to be wrong. Can't you use function calls? There is still a problem with the method I use. Looking forward to your reply, thank you

////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// std::string key1("LAYOUT_PATH_KEY_NODE"); std::string key2("VERIFY_KEY_NODE"); std::string input("input_layout"); std::string output("output_layout"); std::string outlevel("output_level");

//case 1 { yyjson_mut_val* child1 = yyjson_mut_obj(doc); yyjson_mut_obj_add_val(doc, doc->root, "ROOT", child1); getOrCreateChildMutObj(doc, child1, "key2"); getOrCreateChildMutObj(doc, child1, "key23");

yyjson_mut_val* layoutKeyNode = getOrCreateChildMutObj(doc, child1, key1);
yyjson_mut_val* arryNode = getOrCreateArray(doc, layoutKeyNode, outlevel);

 //Is there a problem with inserting data like this？？？
std::vector<std::string> v{"kkkkk33333", "wwwwwwwwww", "rrrrrrrrrr", "qqqqqqqqqqqqq"};
for(size_t i = 0; i < v.size(); ++i)
    yyjson_mut_arr_add_strcpy(doc, arryNode, v[i].data());

 #This way of access is correct, but how do I want to dynamically insert data? 
//         yyjson_mut_arr_add_strcpy(doc, arryNode, "yyyyyyy");

// yyjson_mut_arr_add_strcpy(doc, arryNode, "out/debug/bin/config.json"); // yyjson_mut_arr_add_strcpy(doc, arryNode, "out/debug/bin/config2.json"); // yyjson_mut_arr_add_strcpy(doc, arryNode, "ttxttttt");

}

output: "ROOT": { "key2": {}, "key23": {}, "LAYOUT_PATH_KEY_NODE": { "�\u0000\u0000\u0000\u0000\u0000\u0000\u0000�\u0000\u0000\u0000": [ "kkkkk33333", "wwwwwwwwww", "rrrrrrrrrr", "qqqqqqqqqqqqq" ] } }

Hi ibireme how do I want to dynamically insert data?

for example ： std::vectorstd::string v{"kkkkk33333", "wwwwwwwwww", "rrrrrrrrrr", "qqqqqqqqqqqqq"}; yyjson_mut_val* arryNode; //obj or arry for(size_t i = 0; i < v.size(); ++i) yyjson_mut_arr_add_strcpy(doc, arryNode, v[i].data());

The file name suffix is .cpp, then compile with g++ ，Can I use g++ to compile?
