使用WireMock作为响应设置Content-Length HTTP标头

Question

看来，wiremock将覆盖Content-Length标头对象。我期望内容长度能够被resposne.body（）。contentLength（）读取。请参见下面的测试案例：

import com.github.tomakehurst.wiremock.WireMockServer; 
import static com.github.tomakehurst.wiremock.client.WireMock.aResponse; 
import static com.github.tomakehurst.wiremock.client.WireMock.get; 
import com.github.tomakehurst.wiremock.core.Options; 
import com.google.common.net.HttpHeaders; 
import java.io.IOException; 
import okhttp3.OkHttpClient; 
import okhttp3.Response; 
import org.junit.Assert; 
import org.junit.Test; 

public class WireMockTest { 

    @Test 
    public void wireMockTest() throws IOException{ 

     String route = "/test"; 
     long contentLength = 9; 

     //Build the mock server 
     WireMockServer server = new WireMockServer(Options.DYNAMIC_PORT); 
     server.stubFor(get(route) 
      .willReturn(aResponse() 
       .withHeader(HttpHeaders.CONTENT_TYPE, "image/png") 
       .withHeader(HttpHeaders.CONTENT_LENGTH, String.valueOf(contentLength)) //Does not work, gets overwritten with -1 by okhttp (means it's not found) 
       .withBody("TEST-BODY") 
      ) 
     ); 
     server.start(); 

     //Hit the server with okHttp 
     String mockRequestURL = "http://localhost:" + server.port() + route; 
     okhttp3.Request serverRequest = new okhttp3.Request.Builder().url(mockRequestURL).build(); 
     OkHttpClient client = new OkHttpClient.Builder().build(); 
     Response resposne = client.newCall(serverRequest).execute(); 

     //Verify the content length is not set 
     Assert.assertEquals("The content length was not read correctly", contentLength, resposne.body().contentLength()); 
    } 
}

我能得到它尊重头时，我被发送到服务器的请求添加的路由。

@Test 
public void wireMockTest() throws IOException{ 

    String route = "/test"; 
    String body = "Hello World!"; 

    //Build the mock server 
    WireMockServer server = new WireMockServer(Options.DYNAMIC_PORT);  
    server.start(); 

    //Configure okHttp 
    OkHttpClient client = new OkHttpClient.Builder().build(); 
    String mockServerURL = "http://localhost:" + server.port(); 

    //Add the route to the server using JSON 
    okhttp3.Request configRequest = new okhttp3.Request.Builder().url(mockServerURL + "/__admin/mappings") 
      .post(RequestBody.create(MediaType.parse("application/json"), 
       "{\n" + 
       " \"request\": {\n" + 
       "  \"method\": \"GET\",\n" + 
       "  \"url\": \"" +route + "\"" + 
       " },\n" + 
       " \"response\": {\n" + 
       "  \"status\": \"200\",\n" + 
       "  \"body\": \""+body+"\",\n" + 
       "  \"headers\": {\n" + 
       "   \"Content-Type\": \"text/plain\",\n" + 
       "   \"Content-Length\": \""+body.length()+"\"\n" + 
       "  }\n" + 
       " }\n" + 
       "}")).build(); 
    client.newCall(configRequest).execute(); 

    //Hit the server with okHttp 
    okhttp3.Request serverRequest = new okhttp3.Request.Builder().url(mockServerURL + route).build(); 
    Response resposne = client.newCall(serverRequest).execute(); 

    //Verify the content length is not set 
    Assert.assertEquals("The content length was no read correctly", body.length(), resposne.body().contentLength()); 
}
