带有 KSOAP 的特殊字符

Question

我正在使用 KSOAP2 来调用 Web 服务。我收到了回复，但该回复中的特殊字符未正确显示。

我该如何改变呢？

我可以更改哪些行来强制执行 UTF-8 编码？

Answer 1

我发现编码不是 UTF-8，而是 ISO_8859_1。我将 ISO_8859_1 编码的输入流转换为 UTF-8，现在一切都以应有的方式显示。

Answer 2

老问题，但如果我可以帮助任何人，我会发布我的解决方案。

类似的问题。我搜索了服务器日志，发现我的请求是 ISO-8859-1 编码的，所以服务器响应也有这个字符集。我的解决方案是覆盖 ksoap API。在您提出问题的 HttpTransportSE 类中，在方法调用中，我更改了行：

connection.setRequestProperty("Content-Type", "text/xml");

我希望我的请求是 UTF-8 编码的，所以我添加了：

connection.setRequestProperty("Content-Type", "text/xml;charset=utf-8");

现在，我发送一个 UTF-8 请求，并得到一个 UTF-8 响应。

希望这会有所帮助。

Answer 3

当我尝试将中文字符发送到 php 服务器并且服务器得到 ??? 时，我遇到了类似的问题， 我发现这是 ksoap 的一个错误，请阅读enter link description here 了解详细信息。 此错误已在 ksoap2.6 中修复。
