Java 使用JSON发布外来字符会产生400个字符
我正在尝试使用带有外来字符的JSON发出POST请求,例如上面带有“~”的西班牙语n,但我一直收到此请求和响应错误:Java 使用JSON发布外来字符会产生400个字符,java,android,json,rest,Java,Android,Json,Rest,我正在尝试使用带有外来字符的JSON发出POST请求,例如上面带有“~”的西班牙语n,但我一直收到此请求和响应错误: POST ...

我已经可以用普通的ASCII字符成功地发出POST请求,但现在我支持外语,我需要将外来字符转换为UTF-8(或任何正确的编码),除非有更好的方法
这是我的密码:
JSONObject jsonObject = new JSONObject();
HttpResponse resp = null;
String urlrest = // some url;
HttpPost p = new HttpPost(urlrest);
HttpClient hc = new DefaultHttpClient();
hc = sslClient(hc);
try
{
p.setHeader("Accept", "application/json");
p.setHeader("Content-Type", "application/json");
// setting TimeZone stuff
jsonObject.put("date", date);
jsonObject.put("description", description);
jsonObject.put("numbers", numbers);
String seStr = jsonObject.toString();
StringEntity se = new StringEntity(seStr);
// Answer: The above line becomes new StringEntity(seStr, "UTF-8");
Header encoding = se.getContentType();
se.setContentEncoding("UTF-8");
se.setContentType("application/json");
p.setEntity(se);
resp = hc.execute(p);
当我在se提交之前放置断点并查看它时,字符看起来是正确的
更新:用上面几行的答案更新代码,并用注释标识它。新StringEntity构造函数采用“UTF-8”参数。这是否可能:
jsonObject.toString(“UTF-8”)代码>?否,唯一的参数toString
接受的是一个int
,用于许多缩进。您是否尝试在没有所有这些转换的情况下输入描述?是的,这就是导致此错误的原因。尝试为utf-8提供一个额外的参数new StringEntity…
