插入物我不能讓它工作,從我的web界面插入對象...AppEngine上 - 爪哇 - 從Web界面
我有一個公式推,並就ok了點擊我啓動Java功能...
我EndpointClass已經follwing自動生成插入功能
@ApiMethod(name = "insertQuestion")
public Question insertQuestion(Question question)
{
EntityManager mgr = getEntityManager();
try
{
if (containsQuestion(question))
{
throw new EntityExistsException("Object already exists");
}
mgr.persist(question);
}
finally
{
mgr.close();
}
return question;
}
,我有一個簡單的問題類
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Key key;
private String question;
private String answerCorrect;
private String answerWrong1;
private String answerWrong2;
private String answerWrong3;
public Question(String question, String answerCorrect, String answerWrong1, String answerWrong2, String answerWrong3)
{
this.question = question;
this.answerCorrect = answerCorrect;
this.answerWrong1 = answerWrong1;
this.answerWrong2 = answerWrong2;
this.answerWrong3 = answerWrong3;
}
// + all the getters and setters...
我嘗試添加它像我的網頁如下:
var question = document.formQuestion.elements[0];
var answer = document.formQuestion.elements[1];
var answerWrong1 = document.formQuestion.elements[2];
var answerWrong2 = document.formQuestion.elements[3];
var answerWrong3 = document.formQuestion.elements[4];
var q2 = new Object();
q2.question = question;
q2.answerCorrect = answer;
q2.answerWrong1 = answerWrong1;
q2.answerWrong2 = answerWrong2;
q2.answerWrong3 = answerWrong3;
gapi.client.questionendpoint.insertQuestion({q2}).execute(handleMessageResponse);
//gapi.client.questionendpoint.insertQuestion(q2).execute(handleMessageResponse);
//gapi.client.questionendpoint.insertQuestion({"question": q2}).execute(handleMessageResponse);
但(我想和所有其他的東西),沒有工作......
有人可以告訴我怎麼做是否正確?
好吧,我編輯我的職務,並加入我忘了線補充,描述q2如何初始化的行...我現在沒有使用括號圍繞q2嘗試它,但是那一項沒有工作......我甚至嘗試過使用'gapi.client.question q2 = new gapi。 client.question(問題,答案,答案錯誤1,答案錯誤2,答案錯誤3);'但是,這也沒有工作... gapi工作到目前爲止,我可以列出表格中的所有內容,並且工作正常...也許你有另一個提示?我會看看api資源管理器...也許這可以幫助我... – prom85
我可以分辨一些差異。我也給了端點一個路徑,不知道它是否意味着什麼。它在你自己的機器上本地工作嗎?嘗試調試端點類並檢查它正在接收哪種對象。另請嘗試使用var req = gapi.clientquestionendpoint.insertQuestion(q2).execute(handleMessageResponse);然後用回調的新行 – user1700737
也可以用var req = gapi.clientquestionendpoint.insertQuestion(q2).execute(handleMessageResponse);然後用回調lile的新行req.execute(function(data){});並檢查數據對象是否有任何內容。 – user1700737
