Postman/Retrofit、Okhttp3、SimpleXml、Rxjava通过Soap请求访问WebService

记录一下使用Postman及现在主流的框架来请求Soap webservice。

1.Postman方式
访问地址：http://ip:port/xxx.wsdl
请求类型：POST
Headers: Content-Type:text/xml
Body：

将body设置为raw类型，只需要修改以下xxx部分

 
 
 
    123456
    111111
 
 

好了，现在postman会给你返回结果的

2.Retrofit+OkHttp3方式

public interface InterfaceCollect {

    @Headers({"Content-Type: text/xml;charset=UTF-8"})//请求的Action，类似于方法名
    @POST("xxx.wsdl")
    Observable request(@Body RequestEnvelope requestEnvelope);
}

public class InterfaceService {

    private Retrofit retrofit;
    private InterfaceCollect interfaceCollect;
    private static Strategy strategy = new AnnotationStrategy();
    private static Serializer serializer = new Persister(strategy);

    private InterfaceService() {
        //手动创建一个OkHttpClient并设置超时时间
        OkHttpClient.Builder builder = new OkHttpClient.Builder();
        builder.connectTimeout(CMConfigs.DEFAULT_TIMEOUT, TimeUnit.SECONDS);
        builder.writeTimeout(CMConfigs.DEFAULT_TIMEOUT, TimeUnit.SECONDS);
        builder.readTimeout(CMConfigs.DEFAULT_TIMEOUT, TimeUnit.SECONDS);
        builder.retryOnConnectionFailure(true);
        builder.addInterceptor(new Interceptor() {
            @Override
            public Response intercept(Chain chain) throws IOException {
                Request original = chain.request();

                Request.Builder requestBuilder = original.newBuilder()
                        .header("Content-Type", "text/xml;charset=UTF-8")   // 对于SOAP 1.1， 如果是soap1.2 应是Content-Type: application/soap+xml; charset=utf-8
                        .method(original.method(), original.body());

                Request request = requestBuilder.build();
                return chain.proceed(request);
            }
        });

        retrofit = new Retrofit.Builder()
                .client(builder.build())
                .addConverterFactory(SimpleXmlConverterFactory.create(serializer))
                .addCallAdapterFactory(RxJavaCallAdapterFactory.create())
                .baseUrl(BASE_URL)
                .build();


        interfaceCollect = retrofit.create(InterfaceCollect.class);
    }

    private static class SingletonHolder {
        private static final InterfaceService INSTANCE = new InterfaceService();
    }

    //获取单例
    public static InterfaceService getInstance() {
        return SingletonHolder.INSTANCE;
    }

    private  Subscription toSubscribe(Observable o, Subscriber s) {
        return o.subscribeOn(Schedulers.io())
                .unsubscribeOn(Schedulers.io())
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe(s);
    }

    public void request(Subscriber subscriber, RequestEnvelope envelope) {
        Observable observable = interfaceCollect.request(envelope);
        toSubscribe(observable, subscriber);
    }
}

@Root(name = "soapenv:Envelope")
@NamespaceList({
        @Namespace(reference = "http://www.w3.org/2001/XMLSchema-instance", prefix = "xsi"),
        @Namespace(reference = "http://www.w3.org/2001/XMLSchema", prefix = "xsd"),
        @Namespace(reference = "http://schemas.xmlsoap.org/soap/envelope/", prefix = "soapenv"),
        @Namespace(reference = "http://tempuri.org/xxx.xsd", prefix = "xxx")
})
public class RequestEnvelope {
    @Element(name = "soapenv:Body", required = false)
    public RequestBody body;

}

RequestEnvelope以及子节点RequestBody都是为了拼装body部分(按需拼接)，这里需要在RequestEnvelope中定义好命名空间。

postman中的请求body实现如下：

        RequestEnvelope requestEnvelop = new RequestEnvelope();
        RequestBody requestBody = new RequestBody();
        RequestLoginModel requestModel = new RequestLoginModel();
        requestModel.user = user.getText().toString();
        requestModel.passwd = passwd.getText().toString();
        requestModel.attribute = "http://www.w3.org/2001/XMLSchema";
        requestBody.login = requestModel;
        requestEnvelop.body = requestBody;
        InterfaceService.getInstance().request(new ApiSubscriber() {
            @Override
            public void onNext(ResponseEnvelope responseEnvelope) {

            }
        }, requestEnvelop);

返回的ResponseEnvelope同RequestEnvelope类似，请自行实现。
