未处理的异常：ClientException：接收数据时连接关闭，在颤振中

Question

我正在尝试使用 Eden Ai API 生成图像，但它显示异常。我哪里错了，我不明白。

 static Future<void> getImage(String question) async {

        headers: {
          HttpHeaders.contentTypeHeader: ' application/json',
          HttpHeaders.authorizationHeader: 'Bearer $apiKey'

        body: jsonEncode({

          "resolution": "512x512",
          "num_images": 2
        }));

    final data = await jsonDecode(res.body);

    log('res: ${res.body} + ${res.statusCode}');
  }

Answer 1

您应该像这样使用

keep alive

来改进标题

headers: {
    "Keep-Alive": "timeout=5, max=1"
  }

此外，您还可以使用重试之类的方式尝试

var _client = RetryClient(http.Client(), retries: 3);

最后设置

timeout

.timeout(
  const Duration(seconds: 15),
);
