基本上,我的问题很简单。我正在使用改造作为与我无法控制的服务器进行通信的框架。我想在我的请求上设置某种标记,它会自动在响应中返回。关于如何实现这一点的任何想法?
答案 0 :(得分:0)
我发现了一种复杂且不太酷的方法。
<强> 0。在请求和响应类型中添加标记字段
<强> 1。自定义 <receiver
android:name=".utils.DelayedStartServiceBroadcastReceiver"
android:enabled="true"
android:exported="true" >
</receiver>
添加标记字段:
<强> 2。自定义okhttp3.RequestBody
添加标记字段:
第3。自定义okhttp3.ResponseBody
设置并获取代码:
例如,我对Converter.Factory
和GsonResponseBodyConverter
进行了一些更改:
TagGsonRequestBodyConverter.java:
GsonRequestBodyConverter
TagGsonResponseBodyConverter.java:
@Override public RequestBody convert(T value) throws IOException {
Buffer buffer = new Buffer();
Writer writer = new OutputStreamWriter(buffer.outputStream(), UTF_8);
JsonWriter jsonWriter = gson.newJsonWriter(writer);
adapter.write(jsonWriter, value);
jsonWriter.close();
TagRequestBody requestBody = TagRequestBody.create(MEDIA_TYPE, buffer.readByteString());
requestBody = value.tag;//just for example ,you will need to check type here
return requestBody;
}
}
<强> 4。在创建改造的okhttpClient时添加拦截器,将标记从TagRequestBody传递到TagResponseBody:
@Override public T convert(ResponseBody source) throws IOException {
try {
//the ugly part,for that retrofit will wrap the responseBody with ExceptionCatchingRequestBody.(ExceptionCatchingRequestBody extends ResponseBody)
ResponseBody value = source;
if (value.getClass().getSimpleName().equals("ExceptionCatchingRequestBody")){
ResponseBody temp = null;
try {
Field f = source.getClass().getDeclaredField("delegate");
f.setAccessible(true);
temp = (T) f.get(value);
} catch (Exception e) {
e.printStackTrace();
}
value = temp != null?temp:value;
}
T t = adapter.fromJson(source.charStream());
if (value instanceof TagResponseBody) {
t.tag = ((TagResponseBody)value).tag;
}
return t;
} finally {
value.close();
}
因此标签被保持:
RequestDataWithTag - CustGsonRequestBodyConverter - &gt; RequestBodyWithTag - 拦截器 - &gt; ResponseBodyWithTag - CustGsonResponseBodyConverter - &gt; ResponseDataWithTag
