原位解析打印出错

[xuandu]

我尝试使用原位解析，而不是parse进行字符串内容的修改，因为文档中说，原位解析可节省内存开销；但是当我进行字符串替换的时候，返回时OK的可是打印的时候却把我原本正常的字符给修改了

rapidjson::PrettyWriterrapidjson::StringBuffer* jWriter = new rapidjson::PrettyWriterrapidjson::StringBuffer(m_rapidJsonStrBuf);

if (!jWriter) {
    return false;
}

jWriter->StartObject();

jWriter->Key("version");
jWriter->String("0.0.0");

jWriter->Key("config");
jWriter->Bool(true);

jWriter->Key("type");
jWriter->String("");

jWriter->Key("id");
jWriter->String("");

jWriter->Key("fill");
jWriter->StartArray();

jWriter->StartObject();
jWriter->Key("eff");
jWriter->String("");
jWriter->EndObject();
jWriter->EndArray();

jWriter->EndObject();

delete jWriter;
jWriter = nullptr;

////////////////////////////////////////////////////////////
rapidjson::Document doc_parse;
rapidjson::Document::AllocatorType& fill_allocator = doc_parse.GetAllocator();

    doc_parse.ParseInsitu(const_cast<rapidjson::MemoryStream::Ch*>( m_rapidJsonStrBuf.GetString()));
   
    doc_parse["id"].SetString("configcontroller-g");
    doc_parse["type"].SetString("controller-g");
   
    rapidjson::Value& fil = doc_parse["fill"];
    assert(fil.IsArray());
    fil[0].GetObject()["eff"].SetString("g-controller");

    rapidjson::Value object(rapidjson::kObjectType);
    object.AddMember("g-param",10, fill_allocator);
    filters[0].GetObject().AddMember("parameter", object, fill_allocator);
   
   

    rapidjson::PrettyWriter<rapidjson::StringBuffer> writer(m_rapidJsonStrBuf);
    m_rapidJsonStrBuf.Clear();
    writer.Reset(m_rapidJsonStrBuf);
    doc_parse.Accept(writer);
    std::string  str =  m_rapidJsonStrBuf.GetString();
    printf(":::%s \n",str.c_str());

在我打印输出的时候，发现部分原本我没有修改的也给我改坏了，如ID显示成了RO
