C嵌套python，oss下载遇oss2.exceptions.RequestError

if (!(pFunc = PyDict_GetItemString(pDict, "Auth"))) {
        cout << "Failed to get Function Auth()";
        return false;
    }
if (!(authR = PyObject_CallFunction(pFunc, "(ss)", authID, authSec))) {
        cout << "Auth exec failed!";
        return false;
    }
if (!(pFunc = PyObject_GetAttrString(pModule, "Bucket"))) {
        cout << "Failed to get Function Bucket()";
        return false;
    }
if (!(bucketR = PyObject_CallFunction(pFunc, "Oss", authR, endpoint, bucket))) {
        cout << "Bucket exec failed!" << endl;
        return false;
    }
char* getobject = "get_object_to_file";
PyObject_CallMethod(bucketR, getobject,"(su)",filename,pathname);

主要代码就是这一部分，执行完返回
Exception oss2.exceptions.RequestError: RequestError() in <module 'threading' from 'C:\Python27\Lib\threading.pyc'> ignored

你好，我现在这个代码逻辑上有错误么？
我用C SDK和python sdk以及C调用python代码/文件都走通过了.
我感觉按照逻辑应该是没问题的,但是为什么出现这个RequestError我也不知道为什么,,能否给点提示呢?解决这个bug

你好，我个人昨天解决了这个bug了，主要还是传参引起的错误。谢谢你的回答，你的代码也有借鉴意义，谢谢

RequestError表明是底层的http库（requests）返回了异常，通常是访问不通等问题导致。

oss有C SDK，你是不是考虑直接用C SDK？或者自己先写一个python代码把完整的逻辑走通，然后用C调用你那个python代码。
-------------------------

我写了一段测试代码，没有问题。但是如果我把 endpoint 填错的话，就碰到和你一样的错误。

请你检查下 endpoint 是否正确，自己可以curl一下。

测试代码如下（注意：不是生产代码，错误处理，内存释放基本没有做）：

#include <Python.h>

PyObject* GetCallable(PyObject* module, const char* name)
{
    PyObject* creator = PyObject_GetAttrString(module, name);
    if (!creator) {
        printf("%s not found\n", name);
        return NULL;
    }

    if (!PyCallable_Check(creator)) {
        printf("%s is not callable\n", name);
        Py_DECREF(creator);

        return NULL;
    }

    return creator;
}

int
main(int argc, char *argv[])
{
    const char* accessKeyId = "<填写正确的值>";
    const char* accessKeySecret = "<填写正确的值>";

    const char* endpoint = "http://oss-cn-hangzhou.aliyuncs.com";   /* take hangzhou region as an example */
    const char* bucketName = "<填写正确的值>";

    Py_Initialize();

    PyObject* moduleName = PyString_FromString("oss2");
    if (!moduleName) {
        printf("bad module name\n");
        exit(1);
    }

    PyObject* module = PyImport_Import(moduleName);

    if (!module) {
        printf("module not found");
        exit(1);
    }

    PyObject* authCreator = GetCallable(module, "Auth");
    if (!authCreator) {
        exit(1);
    }

    PyObject* bucketCreator = GetCallable(module, "Bucket");
    if (!bucketCreator) {
        exit(1);
    }

    PyObject* auth = PyObject_CallFunction(authCreator, "ss", accessKeyId, accessKeySecret);
    if (!auth) {
        printf("failed to instantiate auth\b");
        exit(1);
    }

    PyObject* bucket = PyObject_CallFunction(bucketCreator, "Oss", auth, endpoint, bucketName);
    if (!bucket) {
        printf("failed to instantiate bucket\n");
        exit(1);
    }

    PyObject_CallMethod(bucket, "get_object_to_file", "ss", "test.txt", "local.txt");

    Py_Finalize();

    printf("done\n");

    return 0;
}
