使用 Java 通过 HTTP POST 发送 JSON答案

【问题标题】：Sending JSON over HTTP POST with Java使用 Java 通过 HTTP POST 发送 JSON
【发布时间】：2015-06-06 15:42:12
【问题描述】：

发件人

StringBuilder builder = new StringBuilder();
HttpParams httpParameters=new BasicHttpParams();
HttpResponse response;
HttpPost httpPost = new HttpPost(address);
StringEntity entity = new StringEntity(JSON.toString(), HTTP.UTF_8);
entity.setContentType("application/json");
httpPost.setEntity(entity);
HttpClient client = new DefaultHttpClient(httpParameters);
response = client.execute(httpPost);

接收者

StringBuffer jb = new StringBuffer();
String line = null;
BufferedReader reader = request.getReader();
while ((line = reader.readLine()) != null)
    jb.append(line);

json_in = org.json.HTTP.toJSONObject(jb.toString());

JSONObject js=new JSONObject((String)json_in.get("Method"));

Map<String, String> dict = new HashMap<>();
Iterator it=js.keys();
while(it.hasNext()){
     String key=(String)it.next();
     dict.put(key,(String) js.get(key));
}

您好，我正在尝试使用 http post 传递 JSON，错误来自行 JSONObject js=new JSONObject((String)json_in.get("Method"));

org.json.JSONException: Unterminated string at 314 [character 315 line 1]

如何解决？谢谢。

【问题讨论】：

你可以通过修复你的json来修复它。
检查 JSON 字符串
可能是因为它包含base64编码的字符串？
与 JavaScript 不那么严格的对象表示法不同，JSON 不允许您在单引号和双引号之间进行选择。 JSON 中只允许使用双引号来分隔字符串值。

根据Wormbo 在评论中所说，您的 JSON 应该如下所示：

我使用漂亮打印的格式化程序 here 检查了 JSON，它在您的应用程序中显示了相同的错误。
