Question

    Request request = new Request.Builder()
            .url("http://example.com")
            .post(RequestBody.create("foo",MediaType.get("text/plain")))
            .build();

client.newCall(request).enqueue(new Callback() {
             
                @Override
                public void onFailure(Call call, IOException e) {
                    //e.printStackTrace();
                    RequestBody b = call.request().body();
                    String t= b.toString(); ??? <-How would I get the original message?
                }

                @Override
                public void onResponse(Call call, Response response) throws IOException {
                    //do something
                     
                }
            });

失败时，我试图保存我发送的原始消息。

我查看了函数，但似乎无法弄清楚如何获取我在回调中发送的原始消息。有没有办法让消息回来？

Answer 1

如果有人正在寻找这个：

Buffer b = new Buffer();
call.request().body().writeTo(b)
String result=b.readString(Charset.defaultCharset()); //Change this to whatever your character set is

除了您的回答之外，您还可以定义一个 Interceptor 并记录那些失败的请求。以此为例，不带任何条件：

class ReqInterceptor implements Interceptor 
{
   @Override
   public Response intercept(Interceptor.Chain chain) throws IOException
   {
     Request request = chain.request();  // original Request
     logger.info(String.format("Sending request %s on %s%n%s",
                 request.url(), chain.connection(), request.headers()));

     Response response = chain.proceed(request);
     logger.info(String.format("Received response for %s %s",
                 response.request().url(), response.headers()));
   
     return response;
   }
}

然后在客户端，类似：

OkHttpClient client = new OkHttpClient.Builder()
            .addNetworkInterceptor(new ReqInterceptor()) //<--this
            .build();

Request request = new Request.Builder()
        .url("http://example.com")
        .post(RequestBody.create("foo",MediaType.get("text/plain")))
        .build();

Response response = client.newCall(request).execute();
response.body().close();

有两种类型，甚至 Interceptor 的 two defined implementations，但网络一种会提供通过线路传输的相同数据，因此如果需要确切信息，您可以选择此：

有没有办法从 okhttp3 的 onfailure 获取原始 http post 消息？
