我不知道为什么getParams()在我的方法中不起作用?
System.out.println在getHeaders下运行正常但在getParams下运行不正常吗?
//---------------------------------------POST request with headers---------------------------------------
public void post(String url, final String param1, final String param2, String source) {
// Request a string response from the provided URL.
JsonObjectRequest request = new JsonObjectRequest(Request.Method.POST, url,
getReponse(source), createMyReqErrorListener()) {
@Override
protected Map<String, String> getParams() throws AuthFailureError {
HashMap<String, String> params = new HashMap<>();
params.put("loginAlias", "username");
params.put("loginPassword", "12345");
System.out.println("Params are: " + params.toString());
return params;
}
@Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<>();
headers.put(ACCEPT, ACCEPT_JSON); //Accepting JSON
headers.put(AUTH_ID, AUTH_ID_VALUE);
headers.put(PLATFORM, PLATFORM_VALUE);
headers.put(CID, "");
headers.put(DEVICE_TYPE_MOBILE, DEVICE_TYPE_MOBILE_VALUE);
System.out.println("Headers are: " + headers.toString());
return headers;
}
};
// Add the request to the RequestQueue.
queue.add(request);
}
我已经关注了所有Google Volley文档并在SO上尝试了几个选项,但由于某些原因,这不起作用?

也面临同样的问题,最后我发现volley有一些问题--JSONObject请求。 (经过几次谷歌搜索!)
getParams()不会调用,因为 JsonObjectRequest 扩展 JsonRequest 会调用 getBody()直接将构造函数第二个参数(call requestBody)编码为contentType,这就是它忽略 getParam()方法的原因。
尝试这个解决方案,它解决了我的问题。
eAX = actxserver('Excel.Application');
mywb = eAX.Workbooks.Open('C:\test.xlsx');
mysheets = eAX.sheets;
numsheets = mysheets.Count;
sheets = cell(1, numsheets);
for ii = 1:numsheets
sheets{ii} = eAX.Worksheets.Item(ii).Name;
end
mywb.Close(false)
eAX.Quit
