将字符串拆分为char *结果失败
// MainInput string = a/b/c
QMessageBox msgBox;
QString qs = QString::fromLocal8Bit(MainInput.c_str());
QStringList list1 = qs.split('/');
// Expected Result:
// "{\"settings\": {\"key\": \"c\",\"server\" : \"a.com\"},\"type\" : \"fixed\"}";
// Now we add one by one to pepare the expected result
char *a = "{\"settings\": {\"key\": \"";
QByteArray ba = list1[2].toLatin1();
char *b = ba.data();
char *c = "\",\"server\" : \"";
QByteArray da = list1[0].toLatin1();
char *d = da.data();
char *e = ".com\"},\"type\" : \"fixed\"}";
char *result;
result = strcpy(result, a); // <<< CRASH / FAIL HERE
result = strcpy(result, b);
result = strcpy(result, c);
result = strcpy(result, d);
result = strcpy(result, e);
msgBox.setText(result);
msgBox.exec();
//data_create_from_json(result);
