我使用标题库授权发布我的服务。（网址没问题）但是我遇到了这个问题。这项服务在邮递员工作正常，但在我的代码不工作。这是邮政服务。我更改了所有连接功能，如urlConnection.setDoOutput，但我总是连接已连接。
StringBuilder sb = new StringBuilder();
HttpURLConnection urlConnection = null;
try {
URL url = new URL(getUrl.trim());
urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setDoInput(true);
urlConnection.setDoOutput(true);
urlConnection.setRequestMethod("POST");
urlConnection.setUseCaches(false);
urlConnection .getResponseCode();
String userPassword = userName + ":" + pwd;
byte[] data = userPassword.getBytes("UTF-8");
String base64UPWD = Base64.encodeToString(data, Base64.DEFAULT);
urlConnection.setRequestProperty("Authorization", "Basic " + base64UPWD);
params.put("token", getToken());
StringBuffer requestParams = new StringBuffer();
Iterator<String> paramIterator = params.keySet().iterator();
while (paramIterator.hasNext()) {
String key = paramIterator.next();
String value = params.get(key);
requestParams.append(key).append("=");
requestParams.append(URLEncoder.encode(value, "UTF-8"));
requestParams.append("&");
}
System.out.println("Req Param: " + requestParams.toString());
urlConnection.setFixedLengthStreamingMode(requestParams.toString().getBytes().length);
urlConnection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
OutputStreamWriter out = new OutputStreamWriter(urlConnection.getOutputStream());
out.write(requestParams.toString());
out.close();
int HttpResult = urlConnection.getResponseCode();
if (HttpResult == HttpURLConnection.HTTP_OK) {
BufferedReader br = new BufferedReader(new InputStreamReader(
urlConnection.getInputStream(), "utf-8"));
String line = null;
while ((line = br.readLine()) != null) {
sb.append(line + "\n");
}
br.close();
getResult = sb.toString();
Log.i("Request Result-->>", getResult);
isSuccess = true;
System.out.println("Response: " + sb.toString());
} else {
System.out.println(urlConnection.getResponseMessage());
}
