[英]Bad request with response code 400, when posting json data to rest api using okHttp 4.*
goal : I'm using sharepoint REST APIs to create a list in my sharepoint site.目标:我正在使用 sharepoint REST API 在我的 sharepoint 站点中创建一个列表。 In this case I'm using okHttp as my Http library.
在这种情况下,我使用 okHttp 作为我的 Http 库。
expected result : should return 201 as response code when calling the request using okHttp.预期结果:使用 okHttp 调用请求时应返回 201 作为响应代码。
actual result :实际结果:
Exception in thread "main" java.io.IOException: unexpected code Response{protocol=http/1.1, code=400, message=Bad Request, url=https://***.sharepoint.com/_api/web/lists}
at com.**.list.ListImpl.createAList(ListImpl.java:39)
at com.**.Test.main(Test.java:16)
following are the steps I have implemented:以下是我实施的步骤:
I have used the postman to test the API.我已经使用邮递员来测试 API。 It worked fine , got the desired result.
它工作正常,得到了想要的结果。
I have debugged the code, expected values were successfully assigned to the respective variables as well.我已经调试了代码,预期值也成功分配给了相应的变量。
I know that 400 bad request means , there is something wrong with JSON data and server couldn't parse the json which I'm sending.我知道 400 个错误的请求意味着 JSON 数据有问题,服务器无法解析我发送的 json。 Eventhough I tried , but couldn't find the way to resolve this.
尽管我尝试过,但找不到解决此问题的方法。 Any help would be appreciated.
任何帮助,将不胜感激。
following are the code samples.以下是代码示例。
ListImple.java ListImpl.java
package com.****.list;
import com.**.app.properties.ApplicationProperties;
import com.**.metadata.MetaData;
import com.**.rest.TokenService;
import okhttp3.*;
import org.json.JSONObject;
import java.io.IOException;
public class ListImpl implements List {
private String api ="/lists";
private MediaType JSON = MediaType.parse("application/json; charset=utf-8");
private final OkHttpClient client = new OkHttpClient();
@Override
public void createAList(String token) throws IOException {
MetaData metaData = new MetaData("SP.List");
ListModel listData = new ListModel(metaData,true,104,
true,"sample description 02", "list-number-02");
JSONObject jsonObject = new JSONObject(listData);
String data = jsonObject.toString();
RequestBody formBody = RequestBody.create(data, JSON);
System.out.println(formBody.contentType());
Request request = new Request.Builder()
.url(ApplicationProperties.getBaseUrl() + api)
.addHeader("Authorization", "Bearer " + token)
.addHeader("Content-Type", "application/json;odata=verbose")
.addHeader("accept", "application/json;odata=verbose")
.addHeader("X-RequestDigest", "0x87D8893C3016E8E7EB288E13276DE7C8D5250EC26025FDADCF9A3E6C86DF0C4A5EC86B3B4AEAD882E06058BC0919A61E10C3DEFDE3B275E67698A9E1B4456CEF")
.post(formBody)
.build();
try (Response response = client.newCall(request).execute()) {
if(!response.isSuccessful()) {
throw new IOException("unexpected code " + response);
}
System.out.println(response.body().string());
}
}
}
After days of debugging I came to conclusion that problem was OkHttp rest library.经过几天的调试,我得出结论,问题是 OkHttp 休息库。 So I removed that library and included the
org.apache.httpcomponents
artifact in the pom.xml file.所以我删除了那个库并在 pom.xml 文件中包含了
org.apache.httpcomponents
工件。 now All are working fine.现在一切正常。
