HTTP 400 Bad Request Error C# -


i'm encountering error: http 400 bad request, possibly error? how check if api correct parameters?

i tried solutions suggested online still no luck. suggest on how resolve issue?

            string url = "/api/customers/reconnect/"; //sample url             string parameters = new javascriptserializer().serialize(new {                  accountnumber = info.accountnumber,                 servicenumber = info.servicenumber,                 lastname = info.lastname,                 processtype = info.processtype,                 reconnectreason = info.reconnectreason,                 priname = info.priname,                 requestdate = info.requestdate,                 amount = info.amount,                 email = info.email,                 priname2 = info.priname2,                 withreconnectfee = info.withreconnectfee,                 contactno2 = info.contactno2,                 stmtfaxno = info.stmtfaxno             });              httpverb method = httpverb.post;              var request = (httpwebrequest)webrequest.create(url);             request.method = method.tostring();             request.contentlength = 0;             request.contenttype = contenttype;             request.accept = "application/json";               var encoding = new utf8encoding();             var bytes = encoding.getbytes(parameters); //encoding.getencoding("iso-8859-1").getbytes(parameters);             request.contentlength = bytes.length;             using (var writestream = request.getrequeststream())             {                 writestream.write(bytes, 0, bytes.length);                 writestream.close();             }                            using (var response = (httpwebresponse)request.getresponse())             {                 var responsevalue = string.empty;                  using (var responsestream = response.getresponsestream())                 {                      if(responsestream != null)                         using (var reader = new streamreader(responsestream))                         {                             responsevalue = reader.readtoend();                         }                 }                  if (response.statuscode == httpstatuscode.ok)                 {                     var jsonval = jobject.parse(responsevalue);                     result = (string)jsonval["result"].tostring();                 }

whenever see error includes three-digit http status code, means able send request on network , able response. status code provided server, not raised .net runtime or on side. (in cases status code might come device between , server, e.g. load balancer or gateway, not problem.)

to understand error of kind, have understand server. in case left out header server deems mandatory, if have provided of headers required http protocol. server doesn't content of body. server has bug. really... on server.

there no way can troubleshoot problem based on c# client code. need contact folks run service , ask them assistance. may able check logs on side determine why server issued 400 status code. or ask them "known good" request message example (including headers); take , compare own message, looking differences may causing problem.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
