发布方法：
public Object getAppData(GetCategoryData mGetFlag) {
nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("email", StaticValues.mStringEmail));
nameValuePairs.add(new BasicNameValuePair("password", StaticValues.mStringPassword));
nameValuePairs.add(new BasicNameValuePair("id", StaticValues.mStringId));
return postHttpURLWithPostMethodTour(AllUrls.mStringWebApiLink + "api/apps", nameValuePairs, mGetFlag);
}
所以我使用post参数进行服务调用，如：
public Object postHttpURLWithPostMethodTour(String url, List<NameValuePair> nameValuePairs, Object mObject) {
HttpPost httppost;
HttpParams httpParameters;
int timeoutConnection = 60000;
HttpClient httpclient = null;
HttpResponse response = null;
String data = "";
isOtherError = false;
System.out.println("Url " + url);
mFillObject = null;
if (check_Internet()) {
try {
mFillObject = mObject.getClass().newInstance();
URL urlToRequest = new URL(url);
HttpURLConnection urlConnection = (HttpURLConnection) urlToRequest.openConnection();
urlConnection.setDoOutput(true);
urlConnection.setRequestMethod("POST");
urlConnection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded; charset=UTF-8");
httppost = new HttpPost(url);
httppost.addHeader("Content-Type", "application/x-www-form-urlencoded;charset=UTF-8");
httppost.addHeader("X-Requested-With", "XMLHttpRequest");
httppost.addHeader("mobile-tokon", StaticValues.mStringMobileToken);
httpParameters = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection);
httpclient = new DefaultHttpClient(httpParameters);
MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
if (nameValuePairs != null) {
for (int index = 0; index < nameValuePairs.size(); index++) {
String paramName = nameValuePairs.get(index).getName();
String paramValue = nameValuePairs.get(index).getValue();
System.out.println("paramName " + paramName);
System.out.println("paramValue " + paramValue);
if (paramName.equalsIgnoreCase("image")) {
if (paramValue.length() > 0) {
System.out.print("File Object found");
entity.addPart(paramName, new FileBody(new File(paramValue)));
}
} else {
entity.addPart(nameValuePairs.get(index).getName(), new StringBody(nameValuePairs.get(index).getValue()));
}
}
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs, "UTF-8"));
}
// Execute HTTP Post Request
response = httpclient.execute(httppost);
System.out.println("httppost " + httppost.toString());
data = EntityUtils.toString(response.getEntity());
System.out.println("Final Data " + data);
mStringresponse = data;
if (data.equalsIgnoreCase("{\"is_device_deleted\":true}"))
setDeviceToken(true);
mFillObject = mGson.fromJson(data, mFillObject.getClass());
} catch (Exception e) {
isOtherError = true;
}
}
return mFillObject;
}
但是，当我打电话给我时，我得到的输出如下：
httppost org.apache.http.client.methods.HttpPost@5359a64c at httpsost.toString（）
所以我知道如何解决这个问题？你的所有建议都很明显。
答案 0 :(得分：0)
为什么要打印出帖子对象？这是没有意义的。您想要打印出结果，而不是post对象。输出的原因与字体无关 - 因为post对象没有更好的toString函数。即使所有结果都是英文的，它也会打印出来。
答案 1 :(得分：0)
试用此代码
private class AysncTaskSend extends AsyncTask<Void,Void,Void>
{
private ProgressDialog regDialog=null;
@Override
protected void onPreExecute()
{
super.onPreExecute();
}
@Override
protected Void doInBackground(Void... params) {
try
{
new Thread(new Runnable() {
@Override
public void run() {
ArrayList<NameValuePair> postParameters = new ArrayList<NameValuePair>();
postParameters.add(new BasicNameValuePair("value1",
"Value1"));
postParameters.add(new BasicNameValuePair("value2",
"value2"));
String response = null;
try {
response = SimpleHttpClient
.executeHttpPost("url",
postParameters);
res = response.toString();
return res;
} catch (Exception e) {
e.printStackTrace();
errorMsg = e.getMessage();
}
}
}).start();
try {
Thread.sleep(3000);
// error.setText(resp);
if (null != errorMsg && !errorMsg.isEmpty()) {
}
} catch (Exception e) {
}
}
catch (Exception e)
{
e.printStackTrace();
}
return null;
}
@Override
protected void onPostExecute(Void result)
{
super.onPostExecute(result);
// do what u do
}
