HTTP 请求 400错误

详细问题

客户端发送请求

public static UserInfo updateUserInfo(UserInfo userInfo) {
    // 创建 OkHttpClient 对象
    OkHttpClient client = new OkHttpClient();
    // 创建请求体
    MediaType JSON = MediaType.parse("application/json; charset=utf-8");
    RequestBody requestBody = RequestBody.create(JSON,
        "{\"id\": " + userInfo.getId() +
        ", \"avatarBase64\"" + userInfo.getAvatarBase64() + "\"" +
        ", \"nickname\": \"" + userInfo.getNickname() + "\"" +
        ", \"bio\": \"" + userInfo.getBio() + "\"" +
        ", \"birthday\": \"" + userInfo.getBirthday() + "\"}");
    // 创建请求对象
    Request request = new Request.Builder()
        .url("http://192.168.43.127:9090/user_info/update_user_info_by_id")
        .post(requestBody)
        .build();

    // 发送请求并处理响应
    client.newCall(request).enqueue(new Callback() {@
        Override
        public void onResponse(Call call, Response response) throws IOException {
            // 处理响应，这里根据具体情况处理更新成功或失败的逻辑
            String responseData = response.body().string();
            // 在这里处理服务器返回的数据
            System.out.println("responseData" + responseData);

        }

        @
        Override
        public void onFailure(Call call, IOException e) {
            // 处理请求失败的情况
            e.printStackTrace();
        }
    });
    return userInfo;
}

服务端接收请求

@PostMapping("/update_user_info_by_id")
public int updateUserInfo(@RequestBody UserInfo userInfo) {
    return userInfoService.updateUserInfo(userInfo);
}

解决方案

将\"avatarBase64\""修改为\"avatarBase64\": \""
即修改请求体：

RequestBody requestBody = RequestBody.create(JSON,
    "{\"id\": " + userInfo.getId() +
    ", \"avatarBase64\"" + userInfo.getAvatarBase64() + "\"" +
    ", \"nickname\": \"" + userInfo.getNickname() + "\"" +
    ", \"bio\": \"" + userInfo.getBio() + "\"" +
    ", \"birthday\": \"" + userInfo.getBirthday() + "\"}");

为

RequestBody requestBody = RequestBody.create(JSON,
    "{\"id\": " + userInfo.getId() +
    ", \"avatarBase64\": \"" + userInfo.getAvatarBase64() + "\"" +
    ", \"nickname\": \"" + userInfo.getNickname() + "\"" +
    ", \"bio\": \"" + userInfo.getBio() + "\"" +
    ", \"birthday\": \"" + userInfo.getBirthday() + "\"}");
