我将查询字符串发布到网址,现在我想获取请求标头并使用其中一个密钥。我写了一个代码,可以获取响应头但不是请求头。到目前为止,这是我的代码:
URL url = null;
try {
url = new URL(getString(R.string.auth_url));
HttpURLConnection con = (HttpURLConnection) url.openConnection();
con.setReadTimeout(10000);
con.setConnectTimeout(15000);
con.setRequestMethod("POST");
con.setDoOutput(true);
con.setDoInput(true);
String urlParameters = "username="+ URLEncoder.encode(params[0], "UTF-8")+"&password="+URLEncoder.encode(params[1], "UTF-8")+"&captcha=1234";
con.setRequestProperty( "charset", "utf-8");
OutputStream os = con.getOutputStream();
BufferedWriter writer = new BufferedWriter(
new OutputStreamWriter(os, "UTF-8"));
writer.write(urlParameters);
writer.flush();
writer.close();
os.close();
BufferedReader reader = new BufferedReader(new InputStreamReader(con.getInputStream()));
StringBuilder stringBuilder = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
stringBuilder.append(line);
}
Log.i("body", "input = " + stringBuilder.toString());
reader.close();
return con.getHeaderFields().toString();
} catch (MalformedURLException e) {
e.printStackTrace();
return null;
} catch (IOException e) {
e.printStackTrace();
return null;
行返回con.getHeaderFields()。toString() 给了我整个响应标题。现在我应该如何更改此代码以获取请求标题?!
提示:我使用了AsyncTask<>以上几行都在我的doInBackground方法中。
答案 0 :(得分:0)
尝试使用:
1)getRequestProperties()
API接收所有请求标头列表
2)getRequestProperty(String field)
API通过字段名称接收相应的标头。
