所以我正在研究Rails并且对我的用户模型感到有点沮丧所以我将其销毁(我也使用了可能是错误来源的设计).在我的辩护中,我感到疲倦,沮丧,并且有点醉意.我尝试用简单的方法将其添加回来rails g scaffold user first:text last:text,但在尝试生成模型时出现以下错误.我如何解决这个问题？

var response = UrlFetchApp.fetch("https://www.google.com/#q=this+is+a+test");
var contentText = response.getContentText();
Logger.log(contentText);
var thisdoc=DocumentApp.getActiveDocument().getBody() ;
thisdoc.setText(contentText);
Logger.log(contentText.indexOf("About"));
但它似乎只返回标题,空体,没有搜索结果.至少我应该能够在浏览器的顶部看到"关于xxx结果",但这不会出现在文本中,indexOf也不会返回正屏幕.我想知道搜索结果是否填充后页面加载意味着正文标记确实是空的,如果有,是否有解决方法？
编辑:不,它不会破坏TOS,因为这是一个GAFE应用程序(这是一个商业应用程序),对于企业帐户,他们有免费和高级模式访问他们的API.
我正在寻找一种方法将一段文本转换为Cocoa中的图像.一切似乎都描述了将图像转换为文本而不是文本转换为图像.
简单地说,我想采取一个词(如"凯文")并将其转换为位图图像来操作并保存为JPEG.
给出答案的人很棒.感谢您提供三种不同且同样有效的方法(是的,我已经对它们进行了测试)....非常酷我希望我能给你所有正确答案.
