阻止 Image.network 对图像 url 进行编码

Question

我正在尝试在列表视图中显示多个图像。所以，我将它们传递给 image.network()。当我运行应用程序时，出现异常：

HTTP request failed, statusCode: 404,
I/flutter ( 4820): https://cdn.mangacruzers.com/file/AnimeRleases/MHA_265_009.jpg%0D

似乎“%0D”附加到 url。简而言之，url 在传递给 Image.network() 时正在被编码。有没有办法阻止这种编码？我已经检查了列表，urls 在传递给 Image.network() 之前没有被编码。

代码：

Widget build(BuildContext context) {
    return Scaffold(
      body: SafeArea(
        child: SingleChildScrollView(
          child: FutureBuilder(
              future: doc,
              builder: (BuildContext context, snapshot) {
                if (!snapshot.hasData)
                  return Center(child: CircularProgressIndicator());
                return ListView.builder(
                  primary: false,
                  shrinkWrap: true,
                    itemCount: chapter.images.length,
                    itemBuilder: (BuildContext context, int index) {
                      return Padding(
                        padding: const EdgeInsets.only(bottom: 10),
                        child: Image.network(chapter.images[index]),
                      );
                    });
              }),
        ),
      ),
    );

编辑：

数据存在于 chapter.images -

Answer 1

%0D 是 URL- 回车 return 的编码值。您可以对 url 进行编码并打印它以查看它是否包含任何 CR。

var encoded = Uri.encodeFull(chapter.images[index]);
print(encoded);

如果它有任何 CR，那么您应该在分配给 Image.network() 之前替换它。

var urlWithoutCR = chapter.images[index].replaceAll(RegExp(r'\r'), "");
Image.network(urlWithoutCR);
