How to use Retrofit Post?

POST request parameters are not typed in the URL, they are typed on the body. For a request like that, you must use a GET request.

What is the difference between #Field and #Query in retrofit

In some POST requests, I don't know when to use #Field with FormUrlEncoded and when to use #Query
For Example:
#POST("list-products-for-sale")
Call<ListAllProductsResponse> getNewProducts(#HeaderMap Map<String,
String> headers,#Query("lastProductId") String lastProductId);
When I tried to use #Field here it was not responding properly and when I switched it to #Query it's working great.
I want to know why #Field isn't working while Query can work perfectly and I did tested in POSTMAN where I sent the data as a formurlencoded and it's giving me the results fin.
EDIT
BTW I'm passing Content-Type:application/json, Accept: application/json with an Authorization key
#Field is used to send #FormUrlEncoded request in Retrofit which hides your parameter and not attach with url to provide security.Used for POST request.
#Query parameter appended to the URL.
If you are using #Field request than it will hides your parameter and not append with the url.
If you are using #Query request than all your parameter is append to your request and visible to users.
Depend on your api request you have to use one of above annotation. If the api request accept the #FormUrlEncoded data than use #Field or if they want to attached it with url than use #Query.
You can get more information from below link :

Adding dynamic header to POST request with body (Retrofit v2.4.0)

I am using Retrofit v2.4.0 in my project. I need to get token using one API call and using this token in header of the POST request I should use another API call where I should add one header and two parameter to the body of the request. The following code is of the second API call (JavaRx is used):
#FormUrlEncoded
#POST("auth/sendCode")
#Headers("Content-Type: application/json")
Single<SendCodeResponse> sendCode(#Header("token") String token,
#Field("phoneNumber") String phoneNumber,
#Field("langCode") String langCode);
However, it is not working. When I log my request, it is showing that the request body is not correct.
What is wrong with my code above?

Why Post method of okhttp occur error [Content-Type header specified in HTTP request is not supported: application/x-www-form-urlencoded]?

I call a Rest API of salesforce by post method:
url = "https://test-dev-ed.my.salesforce.com/services/apexrest/AccountUsers/"
client = OkHttpClient()
val jsonIn = FormBody.Builder()
.add("email",URLEncoder.encode("dt1#gmail.com", "UTF-8"))
.add("password", URLEncoder.encode("1","UTF-8"))
.build()
request = Request.Builder()
.post(jsonIn)
.header("Authorization", "Bearer "+accesstoken)
.addHeader("Content-Type","application/x-www-form-urlencoded")
.url(url)
.build()
response = client.newCall(request).execute()
This is rest api:
#HttpPost
global static ID createUser(String email, String password) {
AccountUser__c us=new AccountUser__c();
us.Email__c=email;
us.Password__c=password;
us.Status__c=0;
insert us;
return us.Id;
}
But result return is error:
[{"errorCode":"UNSUPPORTED_MEDIA_TYPE","message":"Content-Type header specified in HTTP request is not supported: application/x-www-form-urlencoded"}]
I had try change application/json to application/x-www-form-urlencoded , but still can't resolve.
I try call a Get method, it is ok.
Why Post method occur error [Content-Type header specified in HTTP request is not supported]?
I would like to suggest a better resolution. Retrofit Library
Even though it is not mandatory to use Retrofit, these are few eye catchy aspects which makes it reliable and handy in similar use case of yours.
Why to use Retrofit?
Type-safe REST Adapter that makes common networking tasks easy
For POST operations, retrofit helps in assembling what needed to be submitted. Eg:- Generating URL encoded form.
Takes care of URL manipulation, requesting, loading, caching, threading, synchronization, sync/async calls
Helps to generate URL using type-aware generated code tied to specific REST API
Parsing JSON using GSON
Retrofit is an API adapter wrapped over OkHttp
The problem that you are facing can be resolved using retrofit like this.
public interface APIConfiguration{
#Headers({"Accept:application/json",
"Content-Type:application/x-www-form-urlencoded"})
#FormUrlEncoded
#POST("user/registration")
Observable<DataPojo> registrationAPI(#FieldMap(encoded = true) Map<String, String> params);
}
That's it, with few annotation the library takes care of Form URL
Encoding and related dependencies.
As it is inappropriate to start from corresponding Retrofit dependencies and sample code, you can go through Reference One and Reference Two for more details.
As per my understanding just checkout the difference the content type header "application/x-www-form-urlencoded" is inefficient for sending large quantities of binary data or text containing non-ASCII characters. The content type "multipart/form-data" should be used for submitting forms that contain files, non-ASCII data, and binary data.
The content "multipart/form-data" follows the rules of all multipart MIME data streams.
https://www.w3.org/TR/html401/interact/forms.html#h-17.13.4
Also try your http request by setting your content type header as multipart/formdata.

Where in Retrofit build the full JSON before sending it?

I am using retrofit an get Bad Request , I would want to know if there is a place in this library where builds the full JSON in string format before sending it.
If it's about inspecting the JSON at runtime for debugging purposes, you can call setLogLevel(LogLevel.FULL) on your RestAdapter.Builder.
FULL logs the headers, body and metadata for both requests and responses to logcat.
new String(((TypedByteArray) request.getBody()).getBytes());
In order to build a JSON formatted body, create an object with a class whose properties are the same that you want to send to the server. The GSON Library set up (or whichever library you are using) with the RestAdapter should send the request with the body in JSON format.
Also ensure that the call is #POST annotated and the parameter annotd with #Body Below is an example:
#POST("/login")
User login(#Body LoginUser loginUser);

Android Volley Caching - Get Response by URL and Request Body

From my experimenting so far, it appears that Volley accesses its cache based on the URL alone. I would like to know if it also can determine which response it should return based on the combination of URL and request body data.
Is there a setting for this, or and extension point where I can implement this myself.
I don't see anywhere that the request body data is returned in the NetworkResponse object, or I would do the check in the parseNetworkResponse method.
Thanks
You have to override Request.getCacheKey() method to include request body as well, when implementing your custom request.
