如何使用 MockWebServer 在 response.body().string() 中触发 IOException

Question

我有这个改造电话：

api.enqueue(new Callback<ResponseBody>() {

    @Override
    public void onFailure(Call<ResponseBody> call, Throwable t) {
        t.printStackTrace();
    }

    @Override
    public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {

        try {
            if (response.isSuccessful()) { // 200 - 300
                String responseBody = response.body().string();
                ...
            }
        } catch (IOException e) {
            e.printStackTrace()
        }
    }
}

并希望使用 MockWebServer 触发 .string() 中的 IOException。

我试过了

        MockResponse mockResponse = new MockResponse()
            .setResponseCode(200)
            .setSocketPolicy(SocketPolicy.DISCONNECT_DURING_RESPONSE_BODY)
            .setBody("{}");

但这最终会出现在OnFailure。

如何触发IOException？

Answer 1

类似下面的东西

  private void responseBodyFail(Protocol expectedProtocol) throws IOException {
    // Use a 2 MiB body so the disconnect won't happen until the client has read some data.
    int responseBodySize = 2 * 1024 * 1024; // 2 MiB
    server.enqueue(new MockResponse()
        .setBody(new Buffer().write(new byte[responseBodySize]))
        .setSocketPolicy(SocketPolicy.DISCONNECT_DURING_RESPONSE_BODY));
