我想用Java复制一个有效的POST请求。出于测试目的,让我们采取如下信息:'äöõüäöõüäöõüäöõü'
工作POST请求(带有'äöõüäöõüäöõüäöõü'的编码信息):

正如我们在请求正文中所见,'äöõüäöõüäöõüäöõü编码为: %u00E4%u00F6%u00F5%u00FC%u00E4%u00F6%u00F5%u00FC%u00E4%u00F6%u00F5%u00FC%u00E4%u00F6%u00F5%u00FC
现在我要复制它。
让我们使用Java中的charset utf-8对文本进行编码:
String userText = "äöõüäöõüäöõüäöõü";
String encoded = URLEncoder.encode(userText, "utf-8");
结果:%C3%A4%C3%B6%C3%B5%C3%BC%C3%A4%C3%B6%C3%B5%C3%BC%C3%A4%C3 %B6%C3%B5%C3%BC%C3%A4%C3%B6%C3%B5%C3%BC%0A%0A%0A%5BSIZE%3D%221%22%5D%5BI%5D<不一样
让我们尝试ISO-8859-1:
String userText = "äöõüäöõüäöõüäöõü";
String encoded = URLEncoder.encode(userText, "ISO-8859-1");
结果:%E4%F6%F5%FC%E4%F6%F5%FC%E4%F6%F5%FC%E4%F6%F5%FC%0A%0A%0A %5BSIZE%3D%221%22%5D%5BI%5D<<不一样
它们都没有产生与工作示例中相同的编码字符串,但它们都具有相同的输入。我在这里缺少什么?
答案 0 :(得分:4)
%u00E4%u00F6%u00F5%u00FC%u00E4%u00F6%u00F5%u00FC%u00E4%u00F6%u00F5%u00FC%u00E4%u00F6%u00F5%u00FC
我不知道上面的数据被编码为什么,但它不是application/x-www-form-urlencoded; charset=UTF-8
,因为请求声称。这不是此MIME类型的合法数据。
它看起来像是一些UTF-16BE编码形式。
URLEncoder.encode(userText, "utf-8");
将是编码application/x-www-form-urlencoded; charset=UTF-8
值的正确方法,如果这实际上是服务器所期望的。 (ref)
