发送带有参数的解析云代码时，出现IllegalArgumentException

debugcn 发表于 Dev

我在发送带有参数作为HashMap的云代码请求时遇到问题。有趣的是，如果我发送带有空参数的请求，则它的工作效果很好。这是我的请求代码（使用ishmaelMakitla的答案进行了更新）：

Map<String, Object> par = new HashMap<String, Object>();
par.put("ingredients", new String[]{"hey"});
ParseCloud.callFunctionInBackground("", par, new FunctionCallback() {
  @Override
  public void done(Object o, Throwable throwable) {
    Log.v("28", "" + o);
    Log.v("27", "" + throwable.getMessage());
    for (Object obj : (ArrayList)o) {
      Log.v("29",""+((ParseObject) obj).get("title"));
    }
  }

  @Override
  public void done(Object object, ParseException e) {
    Log.v("26", "" + object);
    if (e != null) {
      Log.v("27", "" + e);
    }
    for (Object obj : (ArrayList)object) {
      Log.v("25",""+((ParseObject) obj).get("title"));
    }
  }
});

和我的云代码方法：

Parse.Cloud.define ('getFoo', function (req, res) {
    var arrayIngredients = [];
    arrayIngredients = req.params.ingredients;
    var recepyQuery = new Parse.Query("Foos");
    recepyQuery.find( {
    success: function(result) {
        res.success(result);    
    },
    error: function() {
        res.error("Nothing here");    
    }    
    });
});

该代码可以正常工作，但是如果我取消对par.put（...）部分的注释，则会出现此错误：

    com.parse.ParseException: java.lang.IllegalArgumentException: invalid type for ParseObject: class [Ljava.lang.String;

这是我的错误堆栈：

这是我犯的错误还是Parse存在问题？我正在使用Parse Server和Parse的Android SDK 1.13.0

而不是传递String[]值，只需传递a String，为此，您应该按以下方式更改请求的代码-

Map<String, Object> par = new HashMap<String, Object>();
par.put("ingredients", "someIngredientValue"});
ParseCloud.callFunctionInBackground("getFoo", par, new FunctionCallback() {
  @Override
  public void done(Object o, Throwable throwable) {
    Log.v("28", "" + o);
    Log.v("27", "" + throwable.getMessage());
    for (Object obj : (ArrayList)o) {
      Log.v("29",""+((ParseObject) obj).get("title"));
    }
  } 
//the rest of your code ...

然后在接收端，您说request.params.ingredients-这应该给您'someIngredientValue'。我希望这有帮助。
