我有一个数组，该数组包含图像的图像数量，而另一个是图像大小数组，该数组包含图像大小，也是图像数组。我正在尝试将它们发送到服务器，但每次都失败了。我正在尝试许多例子，但对我没有任何努力。还有其他方法吗？请给我一些提示或链接。
如何在Android中使用凌空发送一系列参数
public void uploadMultipleImage(String url, final List<SelectedImageModel> selectedImageModels)
{
VolleyMultipartRequest multipartRequest = new VolleyMultipartRequest(Request.Method.POST, url, new Response.Listener<NetworkResponse>() {
@Override
public void onResponse(NetworkResponse response) {
String resultResponse = new String(response.data);
responseListener.onResultSuccess(resultResponse);
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
NetworkResponse networkResponse = error.networkResponse;
String result = new String(networkResponse.data);
responseListener.onResultSuccess(result);
}
}) {
@Override
protected Map<String, String> getParams() {
HashMap<String, String> params = new HashMap<>(selectedImageModels.size());
for(int i=0; i<selectedImageModels.size(); i++)
params.put("size["+i+"]",selectedImageModels.get(i).getPhotoSize());
for(int i=0; i<selectedImageModels.size(); i++)
params.put("quantity["+i+"]",selectedImageModels.get(i).getPhotoQuantity());
return params;
}
@Override
public Map<String, String> getHeaders() {
Map<String, String> headers = new HashMap<>();
headers.put("Authorization", "Bearer "+requiredInfo.getAccessToken());
headers.put("Accept", "application/json");
headers.put("Content-Type", "x-www-form-urlencoded");
return headers;
}
@Override
protected Map<String, DataPart> getByteData() {
Map<String, DataPart> params = new HashMap<>(selectedImageModels.size());
for(int i=0; i<selectedImageModels.size(); i++)
params.put("image["+i+"]",new DataPart("imageName",UserProfile.getFileDataFromDrawable(selectedImageModels.get(i).getPhoto())));
return params;
}
};
requestQueue.add(multipartRequest);
}
每次我获得com.android.volley.server错误500此错误
制定一种发送参数数组的方法。
private String makeJsonObjectParams() {
//In mediaData,I am sending image to AWS and I will get the download link and I
//正在下载drowishurl arrayslist中存储下载。
JSONArray mediaData = new JSONArray();
try {
if(img1 != 1) {
JSONObject temp = new JSONObject();
temp.put("file", download_url.get(0));
temp.put("type", "signature");
mediaData.put(temp);
}
if(img2 != 1){
JSONObject temp1 = new JSONObject();
temp1.put("file", download_url.get(1));
temp1.put("type", "id proof");
mediaData.put(temp1);
}
} catch (JSONException e) {
e.printStackTrace();
}
//for sending normal details like text
JSONObject updateDetails = new JSONObject();
try {
updateDetails.put("status", 2);
updateDetails.put("userId", sharedPreferences.getString("user_ID",""));
updateDetails.put("deviceToken", splash_screen.android_id);
} catch (JSONException e) {
e.printStackTrace();
}
JSONObject jsonVerificationDetails = new JSONObject();
try {
jsonVerificationDetails.put("type", verificatin_type);
jsonVerificationDetails.put("durationOfStay", durationOfStay.getText().toString());
jsonVerificationDetails.put("media", mediaData);
} catch (JSONException e) {
e.printStackTrace();
}
JSONObject jsonBody = new JSONObject();
try {
jsonBody.put("verificationDetails", jsonVerificationDetails);
jsonBody.put("updateDetails", updateDetails);
} catch (JSONException e) {
e.printStackTrace();
}
final String mRequestBody = jsonBody.toString();
return mRequestBody;
}
}
通过以下代码将代码发送到服务器。
void submitData(){
try {
RequestQueue requestQueue = Volley.newRequestQueue(MainActivity.this);
final String mRequestBody = makeJsonObjectParams();
StringRequest stringRequest = new StringRequest(Request.Method.POST, completedTaskUrl, new Response.Listener<String>() {
@Override
public void onResponse(String response) {
try {
//do whatever you want
}
} catch (JSONException e) {
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
}
}) {
@Override
public String getBodyContentType() {
return "application/json; charset=utf-8";
}
@Override
public byte[] getBody() throws AuthFailureError {
try {
return mRequestBody == null ? null : mRequestBody.getBytes("utf-8");
} catch (UnsupportedEncodingException uee) {
VolleyLog.wtf("Unsupported Encoding while trying to get the bytes of %s using %s", mRequestBody, "utf-8");
return null;
}
}
@Override
protected Response<String> parseNetworkResponse(NetworkResponse response) {
String responseString = "";
if (response != null) {
responseString = String.valueOf(response.statusCode);
}
// return Response.success(responseString, HttpHeaderParser.parseCacheHeaders(response));
return super.parseNetworkResponse(response);
}
};
requestQueue=Volley.newRequestQueue(getApplicationContext());
requestQueue.add(stringRequest);
} catch (Exception e) {//JSONException e
e.printStackTrace();
}
}
