标签: simple-xml-converter

在我的项目中(我正在使用Dagger 2,Retrofit 2和OkHTTP,RxAndroid)我有2个不同的API调用.从一个我收到JSON,从其他 - XML.我研究了 这个链接并在我的Retrofit.Builder()中添加了2个转换器:

@Provides
@Singleton
public Gson providesGson() {
    return new GsonBuilder().create();
}

@Provides
@Singleton
public Retrofit providesRetrofit(@NonNull OkHttpClient okHttpClient, @NonNull Gson gson) {
    return new Retrofit.Builder()
            .baseUrl(ConstantsManager.BASE_URL)
            .client(okHttpClient)
            .addConverterFactory(SimpleXmlConverterFactory.create())
            .addConverterFactory(GsonConverterFactory.create(gson))
            .addCallAdapterFactory(RxJavaCallAdapterFactory.create())
            .build();
}

但是,当我收到JSON(XML被正确转换)时,我得到以下内容:

(编辑我添加了一个小的演示测试)

我是新手Retrofit.我需要做的是XML从服务器检索文件并将其转换为POJO.问题是我的测试服务器上的所有内容都与静态文件完美配合,但是当我在真实服务器上尝试这个时,我无法使用它Retrofit2,但是当我直接使用时它确实有效OkHttp,所以有些东西是错误的生成Request我猜.

编辑:我切换代码使用String转换器只是简单的事情,因为问题只与响应有关.

这是我的基本实现.

public interface ZedoClient {
@retrofit2.http.Headers({
        "User-Agent: Mozilla/5.0 (Linux; Android 5.1; Quattro_L50_HD LMY47D/Quattro_L50_HD)",
        "Cookie : ZCBC=1;FFcat=3533,3,90;FFad=0;FFMChanCap=5345280B3533,3#2605191|0,1#0,24:"
})
@GET("fns.vast")
Call<Vast> getVast(@QueryMap(encoded=true) Map<String, String> options);

我添加了两个Interceptor以便设置headers和cookies: AddCookiesInterceptor.class

class AddCookiesInterceptor implements Interceptor {
    private final Headers headers;

    AddCookiesInterceptor(Headers headers) {
        this.headers = headers;
    }
    @Override
    public okhttp3.Response intercept(Chain chain) throws IOException {
        Request.Builder builder = chain.request().newBuilder();
        builder.headers(headers);
        return chain.proceed(builder.build());
    }
}

ReceivedCookiesInterceptor.class …

我retrofit2.0在我的应用程序中使用simpleframework.xml库.

问题是当我没有proguard运行应用程序时它工作正常但是当我运行proguard时我在日志中得到以下错误.

E/ERROR: java.lang.RuntimeException: org.simpleframework.xml.core.PersistenceException: Constructor not matched for class A

A类没有/ default构造函数应该可以工作.我还添加了一个No Argument Constructor.但这并没有纠正这个问题.

类一

@Root(name = "data",strict = false)
public class A {
    @Element(name = "baseurl",required = false)
    private String baseURl;
    @Element(name = "country_code")
    private String country_code;

    //  Setters and getters
}

正如您所看到的,没有构造函数(添加默认的空构造函数可以解决问题).所以默认的No Argument Constructor应该也能正常工作.但是,我尝试使用以下构造函数,这将删除错误.

public A(@ELement(name = "baseurl") String baseUrl,
         @Element(name = "country_code") String country_code) {    // Add all the elements from the xml in the constructor i.e. …

我在改造和 XML 方面遇到问题，我使用 SimpleXmlConverterFactory，并且出现此错误： 原因为：“java.lang.IllegalArgumentException：无法找到 java.util.List 的 ResponseBody 转换器。尝试过：
*retrofit2.BuiltInConverters *retrofit2。转换器.simplexml.SimpleXmlConverterFactory”

等级：

compile 'com.google.code.gson:gson:2.8.1'
compile 'com.squareup.retrofit2:retrofit:2.3.0'
compile 'com.squareup.retrofit2:converter-gson:2.3.0'
compile 'com.squareup.okhttp3:okhttp:3.9.0'
compile 'com.squareup.okhttp3:logging-interceptor:3.8.0'
compile ('com.squareup.retrofit2:converter-simplexml:2.3.0') {
    exclude group: 'xpp3', module: 'xpp3'
    exclude group: 'stax', module: 'stax-api'
    exclude group: 'stax', module: 'stax'
}

服务 ：

        Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(URL)
            .client(buildHttpClient())
            .addConverterFactory(SimpleXmlConverterFactory.create())
            .build();

private OkHttpClient buildHttpClient() {
    HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
    interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
    return (new OkHttpClient.Builder())
            .addInterceptor(buildDefaultHeadersInterceptor())
            .addNetworkInterceptor(buildLogInterceptor())
            .build();
}

模型 ：

    @Root(name = "item")
    public class Item {

    @Element(name = …

我在xml中有一个服务器响应，该响应格式不正确，也没有根元素：

<option value="stationAValue">stationADescription</option>
<option value="stationBValue">stationBDescription</option>

我试图这样使用SimpleXmlConverterFactory：

Retrofit retrofit = new Retrofit.Builder()
    .baseUrl(Params.BASE_URL)
    .client(okHttpClient)
    .addConverterFactory(SimpleXmlConverterFactory.create())
    .build();

这是我的类，代表一行：

public class Station {
    @Element(name = "option")
    private String mName;

   @Attribute(required = false)
   private String value;
}

但是，当然，如果没有根元素就无法解析它，是否有一种方法可以在SimpleXmlConverterFactory尝试解析响应之前添加根元素？

还是另一种解决方案？

我正在使用Retrofit开发一个Android应用程序。

服务器正在发送XML作为响应。所以我应该转换它。对于Json，我使用了GsonConverter。对于XMl，我想我可以使用SimpleXMLConverter。

我访问了SimpleXMLConverter的GitHub链接：https : //github.com/square/retrofit/tree/master/retrofit-converters/simplexml

我发现此消息：

不推荐使用-请切换到JAXB转换器

所以我访问了JAXBConverter的Github链接：https : //github.com/square/retrofit/tree/master/retrofit-converters/jaxb

但是我发现了以下消息：

请注意，JAXB在Android上不起作用。

嗯...我应该使用什么xml转换器？...
