Java:预览 HttpPost 请求

Question

我正在尝试使用 Java 将 JSON 格式的数据发送到服务器。信息正在到达服务器，但服务器正在响应“错误请求”。

    HttpPost httpost = new HttpPost(path);

    StringEntity se = new StringEntity(JSONRequest);

    //sets the post request as the resulting string
    httpost.setEntity(se);

    //sets a request header so the page receving the request will know what to do with it
    httpost.setHeader("Accept", "application/json");
    httpost.setHeader("Content-type", "application/json;charset=utf8");
    HttpResponse response = httpclient.execute(httpost);

这是我请求的基本设置。这是 JSONData:

    {"clientApplicationDto":{"AuthenticationToken":"","BrandId":12,"MobileDeviceApplicationId":0},"mobileDeviceInfo":{"CarrierName":"MTN-SA","OsVersion":"2.2.2","ClientApplicationVersion":"TEST","DeviceManufacturer":"HTC","DeviceName":"HTC Desire","DeviceUniqueId":"1e9766fa2ef4c53a","OsName":"8","ClientApplicationTypeId":3}}

如果你们觉得这很合适，我将开始向管理员发送垃圾邮件，但现在，我需要知道我是否遗漏了什么。

Answer 1

我发现了问题...服务器对内容类型 header 和内容格式极其敏感

    httpost.setHeader("Content-type", "application/json;charset=utf8");

需要改成

    httpost.setHeader("Content-type", "application/json; charset=utf-8");

和 StringEntity se = new StringEntity(JSONRequest);

需要改成

     StringEntity se = new StringEntity(JSONRequest,"utf-8");

谢谢 Jens，那条评论将我推向了正确的方向。
