Question

这是我的代码：

  Future<String> fetch(url) async {
    Directory tempDir = await getTemporaryDirectory();
    String tempPath = tempDir.path;
    var cj = new PersistCookieJar(tempPath);

    HttpClient client = new HttpClient();
    var request = await client.getUrl(Uri.parse(url));
    request.cookies.addAll(cj.loadForRequest(Uri.parse(url)));
    var response = await request.close();
    cj.saveFromResponse(Uri.parse(url), response.cookies);
        // I tried using .toString() but it returns an " Instance of '_HttpClientResponse' "
    return response.toString();
  }

我花了几个小时试图找到一种方法来返回响应正文，但没有成功，有人可以帮助我。

没关系，我已修复它。

我使用了以下代码：

  Future<String> fetch(url) async {
    Directory tempDir = await getTemporaryDirectory();
    String tempPath = tempDir.path;
    var cj = new PersistCookieJar(tempPath);

    HttpClient client = new HttpClient();
    var request = await client.getUrl(Uri.parse(url));
    request.cookies.addAll(cj.loadForRequest(Uri.parse(url)));
    var response = await request.close();
    cj.saveFromResponse(Uri.parse(url), response.cookies);
    // I had to transform the response for it to work
    var body = await response.transform(Utf8Decoder(allowMalformed: true)).join();
    return body;
  }

从HttpClient请求返回响应主体
