【问题标题】：Posting Data from android to wcf将数据从 android 发布到 wcf
【发布时间】：2015-04-27 16:41:52
【问题描述】：

我正在尝试将数据从 android 发布到 wcf，但它给出的消息不正确，我能够从服务中检索数据....但无法发布... 这是代码：

HttpPost request = new HttpPost(http://xxx.xxx.x.xx/JsonWcfService/GetEmployees.svc/json/addemp); request.setHeader("接受", "应用程序/json"); request.setHeader("内容类型", "应用程序/json"); 字符串文本 = ""; String not = new String(" ");

try {
    // Build JSON string
    JSONStringer vehicle = new JSONStringer()
        .object()
        .key("rData")
        .object()
        .key("details").value("241|b@h.us|why")
        .endObject()
        .endObject();

    StringEntity entity = new StringEntity(vehicle.toString());

    Toast.makeText(MainActivity.this, vehicle.toString() + "\n", Toast.LENGTH_LONG).show();

    request.setEntity(entity);

    // Send request to WCF service
    DefaultHttpClient httpClient = new DefaultHttpClient();
    HttpResponse response = httpClient.execute(request);
    // Log.d("WebInvoke", "Saving : " + response.getStatusLine().getStatusCode());
    Toast.makeText(MainActivity.this, response.getStatusLine().getStatusCode() + "\n", Toast.LENGTH_LONG).show();
    Stext = response.getStatusLine().toString();
} catch (Exception e) {
    not = "NOT ";
    e.printStackTrace();
}

Toast.makeText(MainActivity.this, not + " OK ! " + "\n" + Stext, Toast.LENGTH_LONG).show();

以下是服务：

[OperationContract]
[WebInvoke(Method = "POST",
ResponseFormat = WebMessageFormat.Json,
RequestFormat = WebMessageFormat.Json,
BodyStyle = WebMessageBodyStyle.Wrapped,
UriTemplate = "json/addemp")]
 bool AddJsonUser(RequestData rData);

public bool AddUser(RequestData rData) {
    bool returnBool = false;

    var data = rData.details.Split('|');
    var response = new EmployeeData {
        empid = data[0],
        empname = data[1],
        emppass = data[2],
    };

    OracleConnection dbConn = new OracleConnection("Data Source=xxx;User Id=xxx;Password=xxxx");
    //string sqlStr = "INSERT INTO signup_table('user_id','user_firstname','user_pass') values('" + data[0] + "', '" + data[1] + "', '" + data[2] +"');";

    string p_name = "signup_proc";
    OracleCommand cmnd = new OracleCommand(p_name, dbConn);
    cmnd.CommandType = CommandType.StoredProcedure;
    cmnd.Parameters.Add("u_id", OracleDbType.Int32).Value = Convert.ToInt32(data[0]);
    cmnd.Parameters.Add("u_name", OracleDbType.Varchar2).Value = data[1];
    cmnd.Parameters.Add("u_pass", OracleDbType.Varchar2).Value = data[2];
    try {
        dbConn.Open();
        if (cmnd.ExecuteNonQuery() != 0) {
            returnBool = true;
        }
        dbConn.Close();
    } catch {
        returnBool = false;
    }
    return returnBool;
}

public bool AddJsonUser(RequestData rData) {
    return AddUser(rData);
}

请帮忙，我不知道发生了什么......

这是logcat.....

【问题讨论】：

..but can't post it.。 i can't figure out what is happering。好吧，从你开始！什么不完全有效？哪些代码被执行，哪些不被执行？错误？例外？你看过logcat吗？它会告诉你很多。
我试图以这种方式弄清楚....int var = response.getStatusLine().getStatusCode();它给了我 400。
然后呢？你期待/看到/得出什么结论？ 400 是什么意思？那条线在哪里？我没看到。
我期望代码 http 响应代码 200，但它给了我 http 响应代码 400，这意味着请求错误....
请发布logcat。

【解决方案1】：

logcat 告诉你你有一个NetworkOnMainThreadException。将您的网络/http 代码放在 AsyncTask 或线程中。从您的代码中删除 Toast()。

【讨论】：

谢谢你的回复......我会把它放在 asynctask 中......但根据 momo 的评论，我已经通过我的浏览器休息插件提出了一些请求......但它给了我错误的请求状态和一条消息......这是“服务器在处理请求时遇到错误。有关更多详细信息，请参阅服务器日志。”......在这种情况下我应该怎么做.......
在这种情况下，您应该查看服务器日志；-)。你在哪个浏览器中使用了什么样的rest插件？但是先把你的代码放在一个 AsyncTask 中，看看你得到什么样的错误/回复。
只需在您的 wcf-webservice 中设置几个断点，然后逐步执行代码。也许有一些 NullPointerException。除了上面的响应，还可以考虑使用现代的 HttpUrlConnection 类而不是旧的 DefaultHttpClient 或者使用像 Retrofit 这样的网络库。
感谢大家.....您的友好回应......我终于解决了......主要问题在我的 .dll 文件中
