Question

我正在尝试使用libcurl PUT数据来模仿命令

curl -u test:test -X PUT --data-binary @data.yaml "http://127.0.0.1:8000/foo/"

正常工作。我的选择如下：

curl_easy_setopt(handle, CURLOPT_USERPWD, "test:test");
curl_easy_setopt(handle, CURLOPT_URL, "http://127.0.0.1:8000/foo/");
curl_easy_setopt(handle, CURLOPT_VERBOSE, 1);
curl_easy_setopt(handle, CURLOPT_UPLOAD, 1);
curl_easy_setopt(handle, CURLOPT_READFUNCTION, read_data);
curl_easy_setopt(handle, CURLOPT_READDATA, &yaml);
curl_easy_setopt(handle, CURLOPT_INFILESIZE, yaml.size());
curl_easy_perform(handle);

我相信read_data功能正常，但如果你问，我会发布该代码。

我正在使用带有django-piston的Django，而我的update函数从未被调用过！（当我使用上面的命令行版本时，被调用。）

libcurl的输出是：

* About to connect() to 127.0.0.1 port 8000 (#0)
*   Trying 127.0.0.1... * connected
* Connected to 127.0.0.1 (127.0.0.1) port 8000 (#0)

我没有给出正确的标题。使用-v运行命令行版本时，它会给出标题

Content-Type: application/x-www-form-urlencoded

使用libcurl添加它：

struct curl_slist *slist = 0;
slist = curl_slist_append(slist, "Content-Type: application/x-www-form-urlencoded");
curl_easy_setopt(handle, CURLOPT_HTTPHEADER, slist);
// ...

curl_easy_perform(handle);

curl_slist_free_all(slist);

它有效！

无法使用libcurl到django-piston的HTTP PUT
