Android 仪器测试 - 使用 OkHttp MockServer.useHttps(...) 时出现 SSLHandshakeException

Question

我正在尝试使用 OkHttps 模拟服务器测试和 REST API。由于 anroid 的限制(在较新的 android 版本中不允许明文 http 请求)，我需要用户 server.useHttps(...)。我尝试使用默认的 SSLSocketFactory。

class RetrofitIntegrationTest {

    private lateinit var server: MockWebServer
    private lateinit var retrofit: Retrofit
    private lateinit var service: InstanceApi

    @Before
    fun setUp() {
        server = MockWebServer()
        server.useHttps(SSLSocketFactory.getDefault() as SSLSocketFactory, false)
        server.start()
        

        retrofit = Retrofit.Builder()
            .addConverterFactory(MoshiConverterFactory.create())
            .baseUrl(server.url("/"))
            .build()

        service = retrofit
            .create(InstanceApi::class.java)
    }

    @After
    fun teardown() {
        server.shutdown()
    }

    @Test
    fun testCompleteIntegration() = runBlocking { 
        server.enqueue(
            MockResponse()
                .setResponseCode(HttpURLConnection.HTTP_OK)
                .setBody(
                    "{ test: 'test' } "
                )
        )

        Timber.i(retrofit.baseUrl().toString())
        val response = service.apiInfo()

        assertEquals(15, response.body()?.version)
    }

运行仪器测试会抛出以下异常:

我已经做了很多研究，但还没有找到任何类似的博客。感谢您提供任何建议或文档链接。

除了使用 server.useHttps，您还可以简单地尝试创建一个网络安全配置，将本地主机列入白名单并将其添加到您的应用中。

首先，创建一个 network_security_config.xml 并将其放入应用程序的 res/xml 文件夹中

<network-security-config>
    <base-config cleartextTrafficPermitted="false" />
    <domain-config cleartextTrafficPermitted="true">
        <domain includeSubdomains="true">localhost</domain>
        <domain includeSubdomains="true">127.0.0.1</domain>
    </domain-config>
</network-security-config>

然后将其添加到您应用的 list 中

<?xml version="1.0" encoding="utf-8"?>
<manifest ... >
    <application android:networkSecurityConfig="@xml/network_security_config"
                    ... >
        ...
    </application>
</manifest>
