我正尝试使用axios包从Node.js使用工作台api创建新的合约实例：
首先，我根据docs的请求创建了服务主体，用于获取承载令牌并访问api资源。
然后，对/ api / v1 / applications / workflows /执行GET请求，并获得以下结果：

}
接下来，基于推论（由于执行发布的文档对于Node.js不够详细），使用axios执行POST，如下所示：
const request = await axios({
method: "POST",
url: `${WORKBENCH_API_URL}/api/v1/contracts?workflowId=27&contractCodeId=27&connectionId=1`,
headers: { 'Authorization': `Bearer ${token.access_token}` },
data: {
workflowActionInput: {
"workflowFunctionId": 101,
"workflowFunctionParameters": [
{
"name": "ingreserutdeljubilado",
"value": "1234567890",
"workflowFunctionParameterId": 99
},
{
"name": "ingresesaldototaldeljubilado",
"value": "250000000",
"workflowFunctionParameterId": 100
},
{
"name": "ingreseelhashdeldocumento",
"value": "FRfIYIfjTDFJHKYT",
"workflowFunctionParameterId": 101
}
]
}
}
});
最后，响应日志显示：

很抱歉，如果内容太长，请确保提供所有细节。这是api问题，代码语法问题还是天蓝色问题？
PD：天青石上的所有渗透都已被授予文档依据。
答案 0 :(得分：0)
遇到类似问题。就我而言，问题出在令牌上。重新创建令牌（不仅调用API，还创建新的API以获取承载令牌）或您使用的任何方法。
