Question

我一直在尝试使用REST api从Dynatrace服务器获取XML响应。当我通过Postman放置url时，我可以轻松获得XML响应，并且我能够从ajax收到'xml'数据类型响应，但不能收到function getXML() { basicAuth = "Basic " + id + ":" + password; $.ajaxSetup({ async: false }); $.ajax({ type: 'GET', url: dynUrl, //this is the function we defined above dataType: 'xml', headers: { 'Authorization': basicAuth //this is for basic authentication, you've already provided UID and PWD above. }, //when we succeed, the function below will be called. success: function(respt) { data = respt; } }); }响应。我计划将这些数据解析为json以备将来使用。

我目前使用的代码是：

function XMLRespond()
{
      getXML();
      //dom = parseXml(data);
      //json = xmlToJson(dom);
      return data;
}

在以下函数中调用它。

data

Failed to open http://localhost:8080/api/Test.html由localhost上托管的html调用并显示。但是，当我运行它时，我得到一个空白的屏幕，控制台说＆＃34; Permission Denied＆＃34;。我的调试器给了我：

非常感谢有关此问题的任何帮助！

解决了这个问题。原来IE（我怀疑其他浏览器）无法直接显示public class chat_app extends AppCompatActivity{ InterstitialAd mInterstitialAd; private InterstitialAd interstitial; private Button btn_send_msg; private EditText input_msg; private TextView chat_conversation; private String user_name,room_name; private DatabaseReference root ; private String temp_key; @Override protected void onCreate(@Nullable Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_chat_room); btn_send_msg = (Button) findViewById(R.id.btn_send); input_msg = (EditText) findViewById(R.id.msg_input); chat_conversation = (TextView) findViewById(R.id.textView); user_name = getIntent().getExtras().get("user_name").toString(); room_name = getIntent().getExtras().get("room_name").toString(); setTitle(" Room - "+room_name); root = FirebaseDatabase.getInstance().getReference().child(room_name); btn_send_msg.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { Map<String,Object> map = new HashMap<String, Object>(); temp_key = root.push().getKey(); root.updateChildren(map); DatabaseReference message_root = root.child(temp_key); Map<String,Object> map2 = new HashMap<String, Object>(); map2.put("name",user_name); map2.put("msg",input_msg.getText().toString()); message_root.updateChildren(map2); } }); root.addChildEventListener(new ChildEventListener() { @Override public void onChildAdded(DataSnapshot dataSnapshot, String s) { append_chat_conversation(dataSnapshot); } @Override public void onChildChanged(DataSnapshot dataSnapshot, String s) { append_chat_conversation(dataSnapshot); } @Override public void onChildRemoved(DataSnapshot dataSnapshot) { } @Override public void onChildMoved(DataSnapshot dataSnapshot, String s) { } @Override public void onCancelled(DatabaseError databaseError) { } }); } private String chat_msg,chat_user_name; private void append_chat_conversation(DataSnapshot dataSnapshot) { Iterator i = dataSnapshot.getChildren().iterator(); while (i.hasNext()){ chat_msg = (String) ((DataSnapshot)i.next()).getValue(); chat_user_name = (String) ((DataSnapshot)i.next()).getValue(); chat_conversation.append(chat_user_name +" : "+chat_msg +" \n\n"); input_msg.setText(""); if(TextUtils.isEmpty(chat_msg)) { Toast.makeText(this, "Empty field ", Toast.LENGTH_SHORT).show(); return; } } `。将data转换为字符串会绕过此问题。
