這個我signup.java類。我發送用戶憑據到服務器錯誤解析數據org.json.JSONException值類型爲java.lang.String <html>

@Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.sign_up); 


     name=(EditText)findViewById(R.id.name); 
     email=(EditText)findViewById(R.id.email1); 
     password=(EditText)findViewById(R.id.password1); 
     phone=(EditText)findViewById(R.id.phone); 
     reg_btn=(Button)findViewById(R.id.button3); 

     reg_btn.setOnClickListener(this); 


    } 


    public void onClick(View v) { 
     // TODO Auto-generated method stub 

     new CreateUser().execute(); 

     } 

    class CreateUser extends AsyncTask<String, String, String> { 

     boolean failure = false; 
     String namestr = name.getText().toString(); 
     String emailstr = email.getText().toString(); 
     String passwordstr = password.getText().toString(); 
     String phonestr= phone.getText().toString(); 

     @Override 
     protected void onPreExecute() { 
      super.onPreExecute(); 
      pDialog = new ProgressDialog(sign_up.this); 
      pDialog.setMessage("Successfull"); 
      pDialog.setIndeterminate(false); 
      pDialog.setCancelable(true); 
      pDialog.show(); 
     }

這裏的TO JSON
轉換

 @Override 
     protected String doInBackground(String... args){ 

      // TODO Auto-generated method stub 
      // Check for success tag 
      int success; 


      try {

       List<NameValuePair> params = new ArrayList<NameValuePair>(); 
       params.add(new BasicNameValuePair("name", namestr)); 
       params.add(new BasicNameValuePair("email", emailstr)); 
       params.add(new BasicNameValuePair("password",passwordstr)); 
       params.add(new BasicNameValuePair("phone", phonestr)); 

       Log.d("request!", "starting"); 

       //Posting user data to script 
       JSONObject json = jsonParser.makeHttpRequest(LOGIN_URL, "POST", params);

打印完整JSON響應

   Log.d("sign up attempt", json.toString()

JSON的成功元素報名屏幕

   success = json.getInt(TAG_SUCCESS); 
       if (success == 1) { 
        Log.d("User Created!", json.toString()); 
        Intent i= new Intent(sign_up.this,donation.class); 
        startActivity(i);

       } 
else{ 
        Log.d("Login Failure!", json.getString(TAG_MESSAGE)); 
        return json.getString(TAG_MESSAGE); 

       } 
      } catch (JSONException e) { 
       e.printStackTrace();

      return null;

API正在返回HTML內容而不是JSON內容。 –

你的API中的問題，它返回的HTML內容。

要測試它並找出問題，請使用Postman或任何其他Restful客戶端發送請求並獲取響應。

錯誤你有..

Value <html> of type java.lang.String cannot be converted to JSONObject

好像你api服務不反應良好。實際上你的api有一些問題。

如果任何REst-api一些html標記值就意味着返回或者一些exception在service提出，由於一些input mismmatch。

我不能告訴你確切的原因，但有幾個更多的原因背後。

我認爲您應該在api網址中收到的String變量中添加一個支票。

String urlResponse = "{}" // suppose this variable holds the response from the URL. 

//then put a check to this variable such that 
if(urlResponse.startsWith("{")){ 

    //in this block you may parse your response from String to JSONObject. 
    JSONObject v_obj = (JSONObject) new parser().parse(urlResponse); 
}else if(urlResponse.startsWith("[")){ 
    //in this block you may parse your response from String to JSONArray. 
    JSONArray v_obj = (JSONArray) new parser().parse(urlResponse); 
    }else{ 
     //write if you don't receive correct response. 
    }

注意： - 如果urlResponse.startsWith("{")回報true那麼它是一個JSONObject類型。如果urlResponse.startsWith("[")返回true那麼它包含JSONArray。

謝謝..
