是否由于PHP代码？
或者是这个java文件中的错误哪个字符应该更改？
错误发生在下载网页任务中。 编辑：
这是具有相同概念的其他代码：
这没有错误

Answer 1

在我看来，查询网址“__http：//suprabha.orgfree.com/ecg/temp.php？name = 10＆amp; temper = 31，w = t”是程序遇到问题的地方。第56个字符是“=”，它不应该是意外。然而，字符串中“31”之前的空格，是否可以成为关注点？如果根据您的设计不需要空格，我建议您删除并尝试它。如果它们是必需的，我会建议在使用它之前将其转义。

希望它有所帮助。

注意：忽略网址前的不受欢迎的。这样做是为了防止超链接。

Answer 2

问题是=符号后面的空格。您可以使用String:trimm()来避免这种情况，但不会解决其他问题，因此，要避免这种情况，请URL's使用java.net.URLEncoder来适应您需要的内容，例如：< / p>

URLEncoder.encode(url, "UTF-8");

在你的情况下：

HttpGet httpGet = new HttpGet(URLEncoder.encode(url, "UTF-8"));

java.lang.IllegalArgumentException：索引56处查询中的非法字符
