我想使用 httpClient 向 web 服务发出 android-json 请求。我尝试调用的方法是“身份验证”该请求应具有以下结构:
{"id":"ID","method":"authenticate","params":{"user":"ANDROID", "password":"PASSWORD", "client":"CLIENT"},"jsonrpc" :“2.0”}
强制参数:?school=SCHOOLNAME
这是我尝试过的:
class MyAsnycTask extends AsyncTask<String, String, String>{
protected String doInBackground(String... params) {
String apiUrl = "https://arche.webuntis.com/WebUntis/jsonrpc.do";
JSONObject jsonParams = new JSONObject();
JSONObject params1 = new JSONObject();
HttpClient client = new DefaultHttpClient();
// Prepare a request object
HttpPost post = new HttpPost(apiUrl);
post.setHeader("Content-type", "application/json");
try {
params1.put("?school","litec");
params1.put("user", "40146720133271");
params1.put("password", "1234567");
jsonParams.put("id", "ID");
jsonParams.put("method", "authenticate");
jsonParams.put("params", params1);
jsonParams.put("jsonrpc", "2.0");
StringEntity se = new StringEntity(jsonParams.toString());
post.setEntity(se);
} catch (JSONException e1) {
e1.printStackTrace();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
// Execute the request
try {
HttpResponse response = client.execute(post);
Log.d("log_response: ", response.getStatusLine().toString());
// Get hold the response entity
HttpEntity entity = response.getEntity();
// if the response does not enclose the entity, there is no need
// to worry about it
if(entity != null){
// a simple JSON Response read
InputStream instream = entity.getContent();
String result;
// convert content of response to bufferedreader
BufferedReader reader = new BufferedReader(new InputStreamReader(instream));
StringBuilder sb = new StringBuilder();
String line = null;
try {
while ((line = reader.readLine()) != null){
sb.append(line + "\n");
}
} catch (IOException e) {
e.printStackTrace();
}finally{
try{
instream.close();
}catch(IOException exp){
exp.printStackTrace();
}
}
result = sb.toString();
Log.d("Result of the Request: ", result);
}
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return "OK";
}
protected String doInBackground(String result) {
return result;
// TODO Auto-generated method stub
}
}
执行此操作后,我收到请求:
{"jsonrpc":"2.0","id":"error","error":{"message":"invalid schoolname","code":-8500}}
所以它告诉我我们的学校名称是假的。那么我该怎么办,我传递参数的方式是错误的吗?
