Question

以下错误是我尝试使用CURL将音频样本（从内存）上传到Nuance的ASR Web服务时获得的错误。我不确定我的代码中的错误在哪里，所以我希望有人可以帮我找出错误的位置。根据回复，错误是无效的应用程序ID或应用程序密钥，但我已直接从我的Nuance帐户粘贴该应用程序ID和密钥并多次检查。

代码应该执行以下操作：

将音频数据发布到Nuance的ASR网络服务
从ASR服务

我的源代码如下所示：

#include "curl.h"


typedef struct {
    unsigned char* buffer;       
    unsigned int   size;         
    unsigned int   index;

CURL* curl;
int status = 0;
char* audioDataPtr = NULL;

unsigned long sizeOfAudioInBytes;
char recognitionResult[4096] = {0};



static size_t read_data(char *bufptr, size_t size, size_t nitems, transfer_state *read_state) {
    size_t read;

    read = min(size * nitems, read_state->size - read_state->index);
    memcpy(bufptr, &(read_state->buffer[read_state->index]), read);
    read_state->index += read;

    return read / size;
}

static size_t write_data (void *ptr, size_t size, size_t nmemb, transfer_state *write_state) {

    memcpy(&(write_state->buffer[write_state->index]), ptr, size * nmemb);
    write_state->index += size * nmemb;

   printf("%s\n", recognitionResult);

   free(audioDataPtr);

    curl_slist_free_all(slist);

   curl_easy_cleanup(curl);

}

这是我执行上述C代码时从服务器返回的内容：

错误401未经授权，无效的应用程序ID   或密钥。

HTTP错误401

问题   访问/ NMDPAsrCmdServlet / dictation。原因是：
    Unauthorized,

..

为了验证我的ASR帐户是否有效，我下载了一个curl可执行文件并执行了以下命令：

curl“https://dictation.nuancemobility.net:443/NMDPAsrCmdServlet/dictation?appId=MYAPPID&appKey=MY128BYTEAPPKEY” - H“Content-Type：audio / x-wav; codec = pcm; bit = 16; rate = 16000”-H“Accept-Language：ENUS”-H“Content-长度：264522“-H”接受：application / xml“-H”Accept-Topic：Dictation“-k --data-binary @ audio_16k16bit.pcm -v

并且工作正常：

我正在做一些非常相似的事情，我通过使用api密钥和通过邮件收到的ID解决了您所面临的问题，而不是http://dragonmobile.nuancemobiledeveloper.com

如果您可以帮助解决以下错误500：

Problem accessing /NMDPAsrCmdServlet/dictation. Reason:

x-nuance-sessionid*********************************

Received QueryRetry: 6 AUDIO_INFO

解决此问题后，当我使用codex发布音频文件时，我收到另一个错误500。不知道如何解决它。

谢谢。
