我正在尝试使用Dropbox API获取Dropbox中某个文件的一些元数据信息。
这是我的邮政编码
std::ostringstream stream;
curl_slist* headers = NULL;
CURL* curl = curl_easy_init();
char data[50];
snprintf(data, sizeof(data), "{\"path\":\"%s\"}", "/3.png");
curl_easy_setopt(curl, CURLOPT_URL, "https://api.dropboxapi.com/2/files/get_metadata");
headers = curl_slist_append(headers, "Authorization: <MY TOKEN>");
headers = curl_slist_append(headers, "\"Content-Type\":\"application/json\"");
curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headers);
curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, write_data);
curl_easy_setopt(curl, CURLOPT_POST, 1);
curl_easy_setopt(curl, CURLOPT_WRITEDATA, &stream);
/* size of the POST data */
curl_easy_setopt(curl, CURLOPT_POSTFIELDSIZE, 30L);
/* pass in a pointer to the data - libcurl will not copy */
curl_easy_setopt(curl, CURLOPT_POSTFIELDS, R"({"path":"/3.png"})"); //Tried data char array it doesn't work too.
CURLcode res = curl_easy_perform(curl);
if (res != CURLE_OK)
return 0;
/* convert stream to string format */
std::string output = stream.str();
curl_easy_cleanup(curl);返回HTTP 400代码
这是我在使用curllib进行http post后得到的错误

</div>在Postman上它给出了很好的响应，但在我的C++代码中它给了我错误，正如你在上面看到的
Http Web请求主体应该如下所示
{
"path": "/3.png"
}这是我从 Postman 那里得到的回应
{
".tag": "file",
"name": "3.png",
"path_lower": "/3.png",
"path_display": "/3.png",

此行：
看起来可疑与所有的内联引号围绕它。
它不应该只是：
您应该使用Fiddler、Charles或类似的HTTP捕获代理工具，将应用程序发送的请求/响应与Postman发送的请求/响应进行比较。我认为，如果上述方法不能解决问题，您将看到一两个差异。
