java - Android Retrofit 2 gzip 错误

Question

我正在使用 retrofit2 开发 android 应用程序。 gzip 有问题，这里是异常堆栈。 我不知道异常到底发生在哪里。任何建议表示赞赏。谢谢。

我检查了 GzipSource 中的代码:

    private void consumeHeader() throws IOException {
        // Read the 10-byte header. We peek at the flags byte first so we know if we
        // need to CRC the entire header. Then we read the magic ID1ID2 sequence.
        // We can skip everything else in the first 10 bytes.
        // +---+---+---+---+---+---+---+---+---+---+
        // |ID1|ID2|CM |FLG|     MTIME     |XFL|OS | (more-->)
        // +---+---+---+---+---+---+---+---+---+---+
        source.require(10);
        ...
    }

  @Override public void require(long byteCount) throws IOException {
    if (!request(byteCount)) throw new EOFException();
  }

  @Override public boolean request(long byteCount) throws IOException {
    if (byteCount < 0) throw new IllegalArgumentException("byteCount < 0: " + byteCount);
    if (closed) throw new IllegalStateException("closed");
    while (buffer.size < byteCount) {
      if (source.read(buffer, Segment.SIZE) == -1) return false;
    }
    return true;
  }

您的响应数据似乎违反了gzip 格式。所以建议先检查响应数据。您可能还需要检查您传入的影响响应数据格式的请求 header (即接受:gzip)。
