我试图将一些数据发布为原始json。但是服务器只接收json对象而不是完整格式的json字符串。以下是我的asyc方法：
public class SendOrderReviewPostRequest extends AsyncTask<backendPlaceOrderRequest, Void, JSONObject> {
@Override
protected JSONObject doInBackground(backendPlaceOrderRequest... backendPlaceOrderRequests) {
try {
if(backendPlaceOrderRequests.length>0){
// URL url = new URL( ServiceGenerator.BASE_URL+"api-v2/placeOrder/review");
URL url = new URL("http://myurl.com");
backendPlaceOrderRequest orderReq = backendPlaceOrderRequests[0];
JSONObject postDataParams = new JSONObject();
postDataParams.put("key", securityKey);
postDataParams.put("storeLanguageId", StoreLanguageId);
JSONArray arrayProduct = new JSONArray();
for(int i = 0; i< orderReq.product.size();i++){
backendPostOrderProduct product = orderReq.product.get(i);
JSONObject postParams = new JSONObject();
postParams.put("id", product.id);
postParams.put("qty", product.qty);
arrayProduct.put(postParams);
}
postDataParams.put("product",arrayProduct);
JSONObject postDataAddress = new JSONObject();
JSONObject postDataAddressBilling = new JSONObject();
postDataAddressBilling.put("firstname", orderReq.addresses.billing.firstname);
postDataAddressBilling.put("lastname", orderReq.addresses.billing.lastname);
postDataAddressBilling.put("street", orderReq.addresses.billing.street);
postDataAddressBilling.put("city", orderReq.addresses.billing.city);
postDataAddressBilling.put("region", orderReq.addresses.billing.region);
postDataAddressBilling.put("postcode", orderReq.addresses.billing.postcode);
postDataAddressBilling.put("telephone", orderReq.addresses.billing.telephone);
postDataAddressBilling.put("customer_address_lat", orderReq.addresses.billing.customer_address_lat);
postDataAddressBilling.put("customer_address_lng", orderReq.addresses.billing.customer_address_lng);
postDataAddressBilling.put("customer_address_opt_phone", orderReq.addresses.billing.customer_address_opt_phone);
JSONObject postDataAdd = new JSONObject();
postDataAdd.put("billing",postDataAddressBilling);
postDataParams.put("addresses",postDataAdd);
JSONObject postDataAddressShipping = new JSONObject();
postDataAddressShipping.put("firstname", orderReq.addresses.shipping.firstname);
postDataAddressShipping.put("lastname", orderReq.addresses.shipping.lastname);
postDataAddressShipping.put("street", orderReq.addresses.shipping.street);
postDataAddressShipping.put("city", orderReq.addresses.shipping.city);
postDataAddressShipping.put("region", orderReq.addresses.shipping.region);
postDataAddressShipping.put("postcode", orderReq.addresses.shipping.postcode);
postDataAddressShipping.put("telephone", orderReq.addresses.shipping.telephone);
postDataAddressShipping.put("customer_address_lat", orderReq.addresses.shipping.customer_address_lat);
postDataAddressShipping.put("customer_address_lng", orderReq.addresses.shipping.customer_address_lng);
postDataAddressShipping.put("customer_address_opt_phone", orderReq.addresses.shipping.customer_address_opt_phone);
JSONObject postDataShip = new JSONObject();
postDataShip.put("shipping",postDataAddressShipping);
postDataParams.put("addresses",postDataShip);
postDataParams.put("coupon", orderReq.coupon);
postDataParams.put("customerId", orderReq.customerId);
postDataParams.put("newCustomerAddress", orderReq.newCustomerAddress);
postDataParams.put("paymentMethod", null);
postDataParams.put("shippingMethod", "firstfreeship_firstfreeship");
JSONObject postDataPayment = new JSONObject();
postDataPayment.put("method", null);
postDataParams.put("payment", postDataPayment);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setReadTimeout(15000 /* milliseconds */);
conn.setConnectTimeout(15000 /* milliseconds */);
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
conn.setDoInput(true);
conn.setDoOutput(true);
OutputStream os = conn.getOutputStream();
BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(os, "UTF-8"));
writer.write(getPostDataString(postDataParams));
writer.flush();
writer.close();
os.close();
int responseCode=conn.getResponseCode();
if (responseCode == HttpsURLConnection.HTTP_OK) {
BufferedReader in=new BufferedReader(
new InputStreamReader(
conn.getInputStream()));
StringBuffer sb = new StringBuffer("");
String line="";
while((line = in.readLine()) != null) {
sb.append(line);
break;
}
in.close();
JSONObject jsonObjRecv = new JSONObject(sb.toString());
return jsonObjRecv;
}
else {
return null;
}
}else {
return null;
}
}
catch (Exception e) {
e.printStackTrace();
if (mProgressDialog!=null && mProgressDialog.isShowing())
mProgressDialog.dismiss();
}
return null;
}
@Override
protected void onPreExecute(){}
@Override
protected void onPostExecute(JSONObject result) {
// Toast.makeText(getApplicationContext(), result,
// Toast.LENGTH_LONG).show();
// backendGetHyperPayTransaction storeLanguage = result.get;
if (mProgressDialog!=null && mProgressDialog.isShowing())
mProgressDialog.dismiss();
try{
if(result.getString("message").equals("success")) {
// backendGetHyperPayTransactionResponse bpor = storeLanguage.getHyperPayTransactionResponse();
// gotoOrderComplete(orderID,orderPageHeading,orderPageContent);
}else{
JSONObject res = result.getJSONObject("result");
if(res != null && res.getString("description") != null){
// Toast.makeText(getApplicationContext(), res.getString("description"), Toast.LENGTH_LONG).show();
AlertDialog.Builder builder1 = new AlertDialog.Builder(CheckoutOrderActivity.this);
builder1.setMessage(res.getString("description"));
builder1.setCancelable(true);
builder1.setPositiveButton(
"Done",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
AlertDialog alert11 = builder1.create();
alert11.show();
}
}
}catch (Exception e) {
e.printStackTrace();
}
}
}
使用下面的方法将json对象转换为字符串：
public String getPostDataString(JSONObject params) throws Exception {
StringBuilder result = new StringBuilder();
boolean first = true;
Iterator<String> itr = params.keys();
while(itr.hasNext()){
String key= itr.next();
Object value = params.get(key);
if (first)
first = false;
else
result.append("&");
result.append(URLEncoder.encode(key, "UTF-8"));
result.append("=");
result.append(URLEncoder.encode(value.toString(), "UTF-8"));
}
return result.toString();
}
我知道问题是因为json字符串无法发送，因为当我尝试将其硬编码为字符串时，它会起作用。
