Question

我是一名Android开发人员。我开发了一个应用程序我有个问题。我想用okhttp multipart数据发送字符串数组数据。但我不能这样做。因为“addFormDataPart”方法是必需的字符串变量。我不能使用该方法（addFormDataPart）。我想发送字符串数组数据。我能做什么？

请帮帮我。

我的源代码：

private void String sendData(String serverURL, String[] arrayData){
RequestBody requestBody;
requestBody = new MultipartBuilder()
                        .type(MultipartBuilder.FORM)
                        .addFormDataPart("arraydata", arrayData)
                        .build();
}

Answer 1

    void String sendData(String serverURL, String[] arrayData){
        String commaSeparatedValues = TextUtils.join(",", arrayData);
        multiPartBuilder.addFormDataPart("key[]", commaSeparatedValues);
    }

注意：这里的关键很重要，应该有“[]”

请试试这个

private void String sendData(String serverURL, String[] arrayData){
  RequestBody requestBody;
  requestBody = new MultipartBuilder()
                    .type(MultipartBuilder.FORM)
                    .addFormDataPart("arraydata", getToString(arrayData))
                    .build();
}

public String getToString(String[] arrayData) {
  StringBuilder stringBuilder = new StringBuilder();
  for (int i = 0 ; i < arrayData.length; i++) {
    stringBuilder.append(arrayData[i]);
    if (i < arrayData.length - 1) {
        stringBuilder.append(",");
    }
  }
  return stringBuilder.toString();
}

MediaType JSON = MediaType.parse("application/json; charset=utf-8");

Map<String, Long> params = new HashMap<String, Long>();
params.put("msisdn", 8801701340061l);

JSONObject parameter = new JSONObject(params);


RequestBody body = RequestBody.create(JSON, parameter.toString());

RequestBody requestBodyy = new MultipartBody.Builder()
        .setType(MultipartBody.FORM)
        .addPart(
                Headers.of("content-type", "form-data; name=\"image\""),
                RequestBody.create(null, "Square Logo"))
        .addPart(
                Headers.of("content-type", "application/json; charset=utf-8"),
                body)
        .build();

Answer 4

把String[] arrayData拼接成"one,two,three"这种形式：

 public String getToString(String[] arrayData) {
    StringBuilder stringBuilder = new StringBuilder();
    for (int i = 0 ; i < arrayData.length; i++) {
        stringBuilder.append(arrayData[i]);
        if (i < arrayData.length - 1) {
            stringBuilder.append(",");
        }
    }
    return stringBuilder.toString();
}

再传值：

.addFormDataPart("arraydata", getToString(arrayData))
