void Dijkstra(ALDirNetwork& graph, int v0, int* dist, int* path) { int mindist, infinity = graph.GetInfinity(); int v, u; for (v = 0; v < graph.GetVexNum(); v++) { dist[v] = graph.GetWeight(v0, v); if (dist[v] == infinity) path[...-Go服务器开发

根据您提供的代码，有几个问题需要修复：

在函数 Dijkstra 中，第一个 for 循环应该从 0 开始遍历到 graph.GetVexNum() - 1，而不是 graph.GetVexNum()。因为顶点索引是从 0 开始的。
在第一个 for 循环内部的 if 语句中，设置了初始路径 path[v] = v0;。但在后续循环中，并没有更新这个初始值，导致最短路径可能无法正确计算。可以将这行代码移动到第一个 for 循环之前。
在函数 OutputShortestPath 中，使用了未定义的变量 endl，应该改为使用换行符 \n。

修正后的代码如下所示：

void Dijkstra(ALDirNetwork<char, int>& graph, int v0, int* dist, int* path)
{
    int mindist, infinity = graph.GetInfinity();
    int v, u;
    for (v = 0; v < graph.GetVexNum(); v++) {
        dist[v] = graph.GetWeight(v0, v);
        if (dist[v] == infinity) path[v] = -1;
        else path[v] = v0;
    }
    
    graph.SetVisitedTag(v0, VISITED);
    for (int i = 1; i < graph.GetVexNum(); i++) {
        u = v0; mindist = infinity;
        for (v = 0; v < graph.GetVexNum(); v++)
            if (graph.GetVisitedTag(v) == UNVISITED && dist[v] < mindist)
            {
                u = v; mindist = dist[v];
            }
        graph.SetVisitedTag(u, VISITED);
        for (v = graph.GetFirstAdjvex(u); v != -1; v = graph.GetNextAdjvex(u, v))
            if (graph.GetVisitedTag(v) == UNVISITED && mindist +
                graph.GetWeight(u, v) < dist[v])
            {
                dist[v] = mindist + graph.GetWeight(u, v); 
                path[v] = u;
            }
    }
}
