I'm creating an android application in which I would like to send some values to the server and in response the server gives me a json response. The values I pass through is of Json post method type.
I would like to know how can I pass the following values to the Json post url:
{
"CPSProfileInfo":
{
"cpsName": "auto",
"userId": "0",
"cpsAddress": "0#0India",
"searchLimit": "10#0",
"searchFlag": "0"
}
}
throught my application so far, I've been using
params.put("cpsName","auto");
But I don't know how to proceed with this type as I don't know how to send the value for CPSProfileInfo
Kindly help me solving this issue!!!
You can go through the tutorial android-json-parsing-tutorial...
First know how json format looks!
To send Json to server, you can try my code:
HttpParams myParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(myParams, 10000);
HttpConnectionParams.setSoTimeout(myParams, 10000);
HttpClient httpclient = new DefaultHttpClient(myParams);
HttpPost httppost = new HttpPost("*your server addresss and query*");
httppost.setHeader("Content-type", "application/json");
//if needed for authorization:
httppost.setHeader("Authorization", "Bearer " + "*Your string token retrieved from server*");
StringEntity se = new StringEntity("*your json here*");
se.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
httppost.setEntity(se);
HttpResponse response = httpclient.execute(httppost);
If you have any questions, please ask.
Checkout Retrofit, it is an awesome networking library by Square.
When posting in retrofit you can just create a class for the object:
#POST("/users/new")
void createUser(#Body User user, Callback<User> cb);
This is posting to the url 'yourdefinedapi.com/users/new with an User object, which is just a POJO object :)
See detailed instructions here: http://square.github.io/retrofit/

I want to send Headers in android to my shoutcast server.
I need to connect this address:
http://s7.voscast.com:8234
and get response. I response is
GET / HTTP/1.(0|1)
Then again send header pass=somePassword
And I want to check what will be the response for pass?
assuming that you are using import org.apache.http.client.*
it would be a simple:
HttpGet request = new HttpGet(url);
request.setHeader("X-AUTHORIZATION", token);
There are also methods like setEntity:
HttpPost request = new HttpPost(url);
request.addHeader("X-AUTHORIZATION", token);
request.addHeader("Content-Type", "application/json");
StringEntity se = new StringEntity(jsonPost);
request.setEntity(se);
see: http://developer.android.com/reference/org/apache/http/client/HttpClient.html
I am working with JSON Restful web serivces where I have to pass JSON object in the Service URL. I have created the JSON object successfully but getting exception when my URL created the HTTP connection with the SERVER.
Below I have mention my URL:
http://72.5.167.50:8084/UpdateProfileInfo?{"ProfileEditId":"917","ContactsEmail":[{"Email":"dsfs","ContactId":""}],"ContactsPhone":[{"CountryId":"+1","Type":"2","Phone":"345345"}],"ProfileId":"290","LastName":"demo","GroupId":"1212","Title":"sdf","City":"dsf","TemplateId":"1212","State":"dsf","AuthCode":"9bcc6f63-2050-4c5b-ba44-b8103fbc377a","Address":"sdf","FirstName":"demo","ContactId":"","Zip":"23","Company":"tv"}
Getting java.lang.IllegalArgumentException: Illegal character in query in code :
int TIMEOUT_MILLISEC = 100000; // 1000 milisec = 1 seconds
int SOCKET_TIMEOUT_MILISEC = 120000; // 2 minutes
HttpParams httpParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParams, TIMEOUT_MILLISEC);
HttpConnectionParams.setSoTimeout(httpParams, SOCKET_TIMEOUT_MILISEC);
HttpClient client = new DefaultHttpClient(httpParams);
HttpPost request = new HttpPost(url);
HttpResponse response = client.execute(request);
responseString = request(response);
Please suggest me If I am doing something wrong with my URL.
*EDITED:*Tried with a key still getting Exeception:
http://72.5.167.50:8084/UpdateProfileInfo?profileinof={"ProfileEditId":"917","ContactsEmail":[{"Email":"sdf","ContactId":""}],"ContactsPhone":[{"CountryId":"+1","Type":"2","Phone":"345345345"}],"ProfileId":"290","LastName":"demo","GroupId":"1212","Title":"dsf","City":"dsf","TemplateId":"1212","State":"dsf","AuthCode":"d968273a-0110-461b-8ecf-3f9c456d17ac","Address":"dsf","FirstName":"demo","ContactId":"","Zip":"23","Company":"tv"}
There is different format of HTTP request that we needed to make for this kind of REQUEST.
I have mention my code below for this.
public JSONObject getJSONObject(){
return jsonObj;
}
ABove method returns me a JSON String which is passed in the below method.
public static HttpResponse makeRequest(String url) throws Exception
{
//instantiates httpclient to make request
DefaultHttpClient httpclient = new DefaultHttpClient();
//url with the post data
HttpPost httpost = new HttpPost(url);
//convert parameters into JSON object
JSONObject holder = getJSONObject();
//passes the results to a string builder/entity
StringEntity se = new StringEntity(holder.toString());
//sets the post request as the resulting string
httpost.setEntity(se);
httpost.setHeader("Accept", "application/json");
httpost.setHeader("Content-type", "application/json");
//Handles what is returned from the page
ResponseHandler responseHandler = new BasicResponseHandler();
return httpclient.execute(httpost, responseHandler);
}
Stack post helped me for doing this task...!!!
The IP is not correct.
IP is formed with 4 bytes. Every byte is a value from 0 to 255, can't be 7 thousand.
http://7232.25.1617.50:1084
Edit: Okay, you edited your question. You're sending a JSON as parameter. But this parameter has no "key".
Should be:
/UpdateProfileInfo?info={"ProfileEditId":"917",[.......]
Edit: I think this should be like this:
/UpdateProfileInfo?info="{'ProfileEditId':'917',[.......]}"
Notice that the value is surrounded by ", and the inner " are replaced now by '
Probably the issue is that you are trying to POST a JSON object as an url param.
If it really has to be an url param, that it has to be urlencoded.
If it rather should be a normal POST request, I's suggest to use a high level helper:
new RESTClient2(ctx).post("http://72.5.167.50:8084", jsonObject);
I can see a need to work with POJOs , converting them to JSON strings and conveying that string info over HTTP. There are lots of good android/java/apache/volley type libs that permit that.
However, i do not understand, in fact i disagree with your requirement to use GET and the URL parms for transport of your JSON string?
Its really easy to do the following:
POJO -> to JSON -> toString -> to http.string.entity -> POST
Why not re-examine your architecture and consider using POST not GET.
Then its easy , 2 step:
see example "request.setEntity( ... "
your code will look like this:
httpPost.setEntity(new StringEntity(pojo.toJSON().toString()));
I want to send the JSON text {} to a web service and read the response. How can I do this from android? What are the steps such as creating request object, setting content headers, etc.
My code is here
public void postData(String result,JSONObject obj) {
// Create a new HttpClient and Post Header
HttpClient httpclient = new DefaultHttpClient();
HttpParams myParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(myParams, 10000);
HttpConnectionParams.setSoTimeout(myParams, 10000);
String json=obj.toString();
try {
HttpPost httppost = new HttpPost(result.toString());
StringEntity se = new StringEntity(obj.toString());
se.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
httppost.setEntity(se);
HttpResponse response = httpclient.execute(httppost);
String temp = EntityUtils.toString(response.getEntity());
Log.i("tag", temp);
} catch (ClientProtocolException e) {
} catch (IOException e) {
}
}
what mistake i have done plz correct me because it shows me an bad request error
but when i do post in poster it shows me status as Successfull 200 ok
I do this with
httppost.setHeader("Content-type", "application/json");
Also, the new HttpPost() takes the web service URL as argument.
In the try catch loop, I did this:
HttpPost post = new HttpPost(
"https://www.placeyoururlhere.com");
post.setHeader(HTTP.CONTENT_TYPE,"application/json" );
List<NameValuePair> nameValuePairs = new
ArrayList<NameValuePair>(1);
nameValuePairs.add(new BasicNameValuePair("json", json));
post.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpClient client = new DefaultHttpClient();
HttpResponse resp = client.execute(post);
HttpEntity entity = resp.getEntity();
response = EntityUtils.toString(entity);
You can add your nameValurPairs according to how many fields you have.
Typically the JSON might become really huge, which I will then suggest gzipping it then sending, but if your JSON is fairly small and always the same size the above should work for you.
If it is a web service and not RestAPI call then, you can get the WSDL file from the server and use a SOAP Stub generator to do all the work of creating the Request objects and the networking code for you, for example WSClient++
If you wish to do it by yourself then things get a little tricky. Android doesn't come with SOAP library.
However, you can download 3rd party library here: http://code.google.com/p/ksoap2-android/
If you need help using it, you might find this thread helpful: How to call a .NET Webservice from Android using KSOAP2?
If its a REST-API Call like POST or GET to be more specific then its is very simple
Just pass a JSON Formatted String object in you function and use org.json package to parse the response string for you.
Hope this helps.
I'm trying to send data through POST to a web server.
Here is the code I'm using to perform the network call:
HttpClient client = new DefaultHttpClient();
HttpConnectionParams.setConnectionTimeout(client.getParams(), 10000);
HttpPost post = new HttpPost(url);
StringEntity se = new StringEntity(json.toString());
se.setContentEncoding("UTF-8");
se.setContentType("application/json");
post.setEntity(se);
HttpResponse response = client.execute(post);
I've verified using jsonlint that json.toString() returns a valid JSON.
I'm getting this error message as a response:
11-29 11:03:53.080: I/Storefront(1470): Response = <HTML><HEAD><TITLE>Service Unavailable</TITLE></HEAD><BODY><H1>Service Unavailable - Zero size object</H1>The server is temporarily unable to service your request. Please try againlater.<P>Reference #15.163431d0.1322593433.2b040d2c</BODY></HTML>
The "Zero size object" message makes me think that the JSON data is not being sent properly.
Because you are receiving a valid response, it is probably an issue with how you are using the server. Make sure you are using the correct URL and sending the data in the expected manner.
I just need to send request to webservice via normal HTTP POST inorder to get response.I passed required parameter on body well.While i run it.,i got "Cannot process the message because the content type 'text/json' was not the expected type 'application/soap+msbin1'." error.When i made research over this.,due to "Web Service required the request to have a specific Content-Type, namely "application/soap+msbin1".When i replaced expected content type.,i got Bad Request error.I donno how to recover from that.
My code:
...
DefaultHttpClient httpClient = new DefaultHttpClient();
ResponseHandler <String> resonseHandler = new BasicResponseHandler();
HttpPost postMethod = new HttpPost("My URL");
postMethod.setHeader( "Content-Type", "text/json");
postMethod.setHeader( "Cache-Control", "no-cache");
JSONObject json = new JSONObject();
json.put("userName", "My Username");
json.put("password", "My Password");
json.put("isPersistent",false);
postMethod.setEntity(new ByteArrayEntity(json.toString().getBytes("UTF8")));
HttpResponse response = httpClient.execute(postMethod);
...
It looks like you are trying to call WCF SOAP service. That service expects correct SOAP communication (= no JSON) and moreover it uses MS binary message encoding of SOAP messages (that is what content type describes) is not interoperable so I doubt you will be able to use it on Android device (unless you find implementation of that encoding for Java / Android).
HttpPost request = new HttpPost(url);
StringEntity entity = new StringEntity(json.toString());
entity.setContentType("application/json;charset=UTF-8"); entity.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE,"application/json;charset=UTF-8"));
request.setHeader("Accept", "application/json");
request.setEntity(entity);
try{
DefaultHttpClient httpClient = new DefaultHttpClient();
response = httpClient.execute(request);
}
Try using something like this. it worked for me.
Thanks.
