Retrofit: Post raw text “user={”key1“: ”value1", etc.}?

问题

So I am pretty new on that library (Retrofit) and actually I am stucked on an atypical case.

I have an API where I try to register (sign up) a new user to it, to test it I use "DHC Rest Client" on Chrome. It works when I send this (see below):

Header:

Content-Type: application/x-www-form-urlencoded

Body (text)

user={"key1": "value1", "key2": "value2", etc.}

So my plan is to make the same thing on Android ! I have created an interface (see below):

Interface

interface RestRegister{
    @Headers("Content-Type: application/x-www-form-urlencoded")
    @POST("/api/register")
    void postRegister(@Body String user, Callback<LoginResponse> callback);
}

But I always get a "Failed!" from the Callback error handler. I correctly get the correct parameters (I give it as a simple String with the correct format - "user={\"email\":\"lol@lol.us\", etc.}").

RestAdapter restAdapter = new RestAdapter.Builder()
                                       .setEndpoint("http://ENDPOINT:3000/")
                                       .build();

                               RestRegister restRegister = restAdapter.create(RestRegister.class);

                               restRegister.postRegister("user={\"email\":\"lol@lol.us\",\"first_name\":\"jean\",\"last_name\":\"loop\",\"password\":\"test95test\",\"gender\":\"1\",\"birthdate\":\"1978/05/16\"}", new Callback<LoginResponse>() {
                                   @Override
                                   public void success(LoginResponse loginResponse, Response response) {
                                       Toast.makeText(SignUp.this, query, Toast.LENGTH_LONG).show();
                                       Toast.makeText(SignUp.this, "Created !", Toast.LENGTH_LONG).show();
                                       Intent intent = new Intent("com.signupconfirmation");
                                       startActivity(intent);
                                   }

                                   @Override
                                   public void failure(RetrofitError error) {
                                       Toast.makeText(SignUp.this, query, Toast.LENGTH_LONG).show();
                                       Toast.makeText(SignUp.this, "Failed !", Toast.LENGTH_LONG).show();
                                   }
                               });
                           }
                       });

Later I would like to create a JSONObject in the right format too ;).

Waiting for your answers :) !

回答1:

This is how the documentation suggests:

@FormUrlEncoded
@POST("/user/edit")
User updateUser(@Field("first_name") String first, @Field("last_name") String last);

In your case it would be:

interface RestRegister{
    @FormUrlEncoded
    @POST("/api/register")
    void postRegister(@Field("user") String data, Callback<LoginResponse> callback);
}

And then:

restRegister.postRegister("{\"email\":\"lol@lol.us\",\"first_name\":\"jean\",\"last_name\":\"loop\",\"password\":\"test95test\",\"gender\":\"1\",\"birthdate\":\"1978/05/16\"}", ...);

回答2:

RestAdapter restAdapter = new RestAdapter.Builder()
                                       .setEndpoint("http://ENDPOINT:3000/")
                                       .build();

Should be

RestAdapter restAdapter = new RestAdapter.Builder()
                                       .setEndpoint("http://ENDPOINT:3000")
                                       .build();

For Example:

 @FormUrlEncoded
 @POST("/alert.php")
 void gettingfirsttimealert(@Field("key") String value, @Field("user_id") String user_id, Callback<JsonResponseis> cb);

JSON Response

{ "success": true,
        "details": {
    "firstname": mathan,
            "arraylist": [
                "subscribe": "subscribe"
    ]
}
}

POJO class should be

public class JsonResponseis{

   // Json response key is String
    public String success;

    //Json response key  is JSON OBJECT
    public Details details;

    public class Details {

        public String firstname;
      //json response  key is arraylist
    public List<ArrayListis> arraylist;

    }

    public class ArrayListis{
        public String subscribe;
    }
}

CallBack Should be

public Callback downloadalertcalback = new Callback() {
    String alertmediapath = "null";
    String ts;
    @Override
    public void success(Object o, Response response) {
        JsonResposeis u = (JsonResposeis ) o;
        if (u.success != null) {

            if (u.success.equalsIgnoreCase("true")) {
                //Do here
            }

        }

    }

    @Override
    public void failure(RetrofitError error) {

    }

};
