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() {@Overridepublic 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);}@Overridepublic 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() + "\"}");
