サービスのPOST操作をJSON要求本体で呼び出し、JSON応答を読み取ろうとしています。JSONObjectをRESTfulサービスに投稿し、Javaを使用して応答を読み取る方法
JSONオブジェクトとしてJSONリクエストを作成する方法は以下のとおりです。
public class CashFundTransfer {
public JSONObject buildRequest(){
JSONObject request = new JSONObject();
request.put("dateTime", getDateTimeObj());
request.put("businessDate", getBusinessDateObj());
request.put("description", getDescriptionObj());
request.put("transferAccount", buildTransferAccount());
request.put("amount", buildAmount());
request.put("businessUnit", buildBusinessUnit());
request.put("status", buildStatus());
request.put("recipient", buildRecipient());
request.put("cashFundTransferee", buildCashFundTransferee());
request.put("enteringAssoc", buildEnteringAssoc());
request.put("approvingAssoc", buildApprovingAssoc());
request.put("accountingDivision", buildAccountingDivision());
return request;
}
}
私がputで呼び出すすべてのメソッドは、親の子ノードであるJSONObjectのオブジェクトを返します。
私のテストクラスでは、私は以下のコードを持っています。コードを実行すると、コンテンツではなくStringEntityオブジェクトのhashcodeがサービスによって取得されます。
public class CFTTest {
CashFundTransfer cft = new CashFundTransfer();
JSONObject request = cft.buildRequest();
System.out.println("request: "+request);
public void callService() throws IOException{
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost postRequest = new HttpPost(url);
try {
String inputString = request.toString();
System.out.println("inputString 1: "+inputString);
StringEntity input = new StringEntity(inputString);
System.out.println("input: "+input);
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
input.setContentType("application/json");
postRequest.setEntity(input);
try {
response = httpClient.execute(postRequest);
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
System.out.println("response: "+response);
}
}
以下はこのコードを実行するときのコンソールです。

ここで私は間違っています。
'JSONObject.toString()'がjson文字列を返さないことは間違いありません。あなたは 'JSONObject.toJSONString()'を使う必要があります。 – sturcotte06
