Question

如何在NewsArticle或BlogPosting中嵌套一个或多个食谱。

我试过了，但Google's Structured Data Testing Tool引发了抱怨recipe1密钥的错误。我不确定将recipe1键更改为：

  <script type="application/ld+json">
{
"@context" : "http://schema.org",
  "@type" : "NewsArticle",
  "author" : { "@type" : "Person",
      "name" : "hgezim"
    },
  "dateModified" : "2016-09-21T06:25:35+00:00",
  "datePublished" : "2016-09-21T06:25:35+00:00",

  },

    "recipeIngredient": [
      "3 or 4 ripe bananas, smashed",
      "1 egg",
      "3/4 cup of sugar"
    ],
    "interactionStatistic": {
      "@type": "InteractionCounter",
      "interactionType": "http://schema.org/Comment",

    "nutrition": {

    },
    "prepTime": "PT15M",
    "recipeInstructions": "Preheat the oven to 350 degrees. Mix in the ingredients in a bowl. Add the flour last. Pour the mixture into a loaf pan and bake for one hour.",
    "recipeYield": "1 loaf",

  }
}
  </script>

Answer 1

这取决于实体彼此之间的关系。您必须使用定义的属性来传达此关系。

要查找合适的媒体资源，请检查BlogPosting以查看具有Recipe或其某种父类型（CreativeWork，Thing）的媒体资源作为预期值。

例如：

about。
hasPart
mentions
...

Answer 2

谢谢@unor。我使用void numberSearch(string fileName) { string searchVal; cout << "\nWhat value would you like to search for?\n"; cin.ignore(); getline(cin, searchVal); ifstream file; //create input file object that will be read from file.open(fileName); //"ifstream file (fileName)" if (!file) { cout << "\nUnable to open file.\n"; exit(1); } string words; int curLine = 0; //file line counter while (getline(file, words)) { ++curLine; //counts each line in the file if (words.find(searchVal) != string::npos) { cout << "\nLine " << curLine << " contains " << searchVal << endl; file.close(); return; } else { cout << "\nThe value " << searchVal << " was not found.\n"; file.close(); return; } } }如下：

hasPart

验证为validates JSON-LD。

schema.org中的多个实体
