我怎么能做一个简单的text / xml POST请求并使用改造2来获取JSON !!! ???
注1 ：我已经知道如何制作JSON GET / POST请求并将JSON作为回复。
note 2 ：我有一个端点，其中请求是XML SOAP格式，响应是JSON格式。为了澄清我会在这里发布样品请求回复：
XML示例请求：
self.scrolled_window = gtk.ScrolledWindow(hexpand=True, vexpand=True)
self.scrolled_window.set_policy(gtk.PolicyType.NEVER, gtk.PolicyType.AUTOMATIC)
JSON样本回复：

答案 0 :(得分：0)
我自己找到了答案，实际上是超级容易的。
APIService类:( RequestBody 是此处的关键）
import okhttp3.RequestBody;
import retrofit2.Call;
import retrofit2.http.Body;
import retrofit2.http.POST;
public interface RetrofitAPIService {
// @Headers("Content-Type: application/json")
@POST("/webservice.asmx?op=Login")
Call<RetrofitResponseBody> login(@Body RequestBody body);
}
注意：以下代码的关键是这一行：
RequestBody requestBody = RequestBody.create(MediaType.parse("text/xml"), requestBodyText);
MainActivity.java：
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
EditText userName = findViewById(R.id.userName);
EditText password = findViewById(R.id.password);
RetrofitAPIService mAPIService = RetrofitAPIUtils.getRetrofitAPIService();
String requestBodyText = "<?xml version=\"1.0\" encoding=\"utf-8\"?>\n" +
"<soap12:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap12=\"http://www.w3.org/2003/05/soap-envelope\">\n" +
" <soap12:Body>\n" +
" <Login xmlns=\"http://tempuri.org/\">\n" +
" <username>" + userName.getText() + "</username>\n" +
" <password>" + password.getText() + "</password>\n" +
" </Login>\n" +
" </soap12:Body>\n" +
"</soap12:Envelope>";
RequestBody requestBody = RequestBody.create(MediaType.parse("text/xml"), requestBodyText);
Call<RetrofitResponseBody> response = mAPIService.login(requestBody);
response.enqueue(new Callback<RetrofitResponseBody>() {
@Override
public void onResponse(Call<RetrofitResponseBody> call, Response<RetrofitResponseBody> response) {
try {
Log.d("JavadR:",
response.body().getUserID().toString() +
" - " +
response.body().getFailureText()
);
} catch (Exception e) {
e.printStackTrace();
}
}
@Override
public void onFailure(Call<RetrofitResponseBody> call, Throwable t) {
}
});
}
RetrofitResponseBody 并不是太重要，但为了保持一致性和方便性，我将在此处发布：
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
public class RetrofitResponseBody {
@SerializedName("UserID")
@Expose
private Integer userID;
@SerializedName("FailureText")
@Expose
private Object failureText;
@SerializedName("UserValidPasswordCode")
@Expose
private Integer userValidPasswordCode;
@SerializedName("UserPatientIsActiveWithNationalIDCode")
@Expose
private Boolean userPatientIsActiveWithNationalIDCode;
public Integer getUserID() {
return userID;
}
public void setUserID(Integer userID) {
this.userID = userID;
}
public Object getFailureText() {
return failureText;
}
public void setFailureText(Object failureText) {
this.failureText = failureText;
}
public Integer getUserValidPasswordCode() {
return userValidPasswordCode;
}
public void setUserValidPasswordCode(Integer userValidPasswordCode) {
this.userValidPasswordCode = userValidPasswordCode;
}
public Boolean getUserPatientIsActiveWithNationalIDCode() {
return userPatientIsActiveWithNationalIDCode;
}
public void setUserPatientIsActiveWithNationalIDCode(Boolean userPatientIsActiveWithNationalIDCode) {
this.userPatientIsActiveWithNationalIDCode = userPatientIsActiveWithNationalIDCode;
}
}
