Question

我想将一个数组作为名称值对发送为httppost.My服务器只接受数组值。以下是我的代码片段..

public String SearchWithType(String category_name, String[] type,int page_no) {

    String url = "http://myURL";
    StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder()
            .permitAll().build();
    StrictMode.setThreadPolicy(policy);

    String auth_token = Login.authentication_token;
    String key = Login.key;

    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost(url);

    try {
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
        nameValuePairs.add(new BasicNameValuePair("authentication_token",
                auth_token));
        nameValuePairs.add(new BasicNameValuePair("key", key));
        nameValuePairs.add(new BasicNameValuePair("category_name",
                category_name));
        int i = 0;
        nameValuePairs.add(new BasicNameValuePair("type", type[i]));
        nameValuePairs.add(new BasicNameValuePair("page", String.valueOf(page_no)));

        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

        HttpResponse response = httpclient.execute(httppost);
        HttpEntity entity = response.getEntity();
        eu = EntityUtils.toString(entity).toString();

    } catch (IOException ioe) {
        String ex = ioe.toString();
        return ex;
    }

    return eu;
}

我遇到了这个问题。方法如下：

try {
    int i = 0;

    List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
    nameValuePairs.add(new BasicNameValuePair("authentication_token", auth_token));
    nameValuePairs.add(new BasicNameValuePair("key", key));
    nameValuePairs.add(new BasicNameValuePair("category_name", category_name));
    nameValuePairs.add(new BasicNameValuePair("type", type[i]));
    nameValuePairs.add(new BasicNameValuePair("page", String.valueOf(page_no)));

    httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

    HttpResponse response = httpclient.execute(httppost);
    HttpEntity entity = response.getEntity();

    eu = EntityUtils.toString(entity).toString();
} catch (Exception e) {
    Log.e(TAG, e.toString());
}

我所要做的就是初始化一个循环：

for (int i = 0; i < type.length; i++) {
    nameValuePairs.add(new BasicNameValuePair("type[]",type[i]));
}

Answer 2

nameValuePairs.add(new BasicNameValuePair("type", Arrays.toString(type)));

从数组转换为字符串，然后使用http post发送，再次将服务器端解析从String转换为数组

json_array = [{param1：＆＃34; param1Value＆＃34;，param2：＆＃34; param2Value＆＃34;}] 如果你想发送一个带有nameValuePairs的json数组，你可以像这样发送;

<Project
  xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <UsingTask TaskName="NppPlugin.DllExport.MSBuild.DllExportTask"
             AssemblyFile="NppPlugin.DllExport.MSBuild.dll"/>
  <Target Name="AfterBuild"
          DependsOnTargets="GetFrameworkPaths"
          >

                   PlatformTarget="$(PlatformTarget)"

                   EmitDebugSymbols="$(DebugSymbols)"
                   DllExportAttributeAssemblyName="$(DllExportAttributeAssemblyName)"
                   DllExportAttributeFullName="$(DllExportAttributeFullName)"
                   Timeout="$(DllExportTimeout)"
                   KeyContainer="$(KeyContainerName)$(AssemblyKeyContainerName)"
