Python水瓶Swagger Flasgger下载Excel

Question

我试图从Swagger返回一个excel文件。使用用Flasgger的Swagger包装器构建的。这是密码-

@app.route('/cluster', methods=['POST'])
def index():
    """
    This API will help you generate clusters based on keywords present in unstructured text
    Call this api passing the following parameters - 
        Dataset Path - <hostname>\\<path to dataset>
        Column Name based on which clustering needs to be done
        Number of Clusters
    Sample URL: http://localhost:8180/cluster/clusters.csv?dataset=\\\\W1400368\\c$\\Users\\VK046010\\Documents\\Python%20Scripts\\RevCycle_PatientAcc.csv&ext=csv&col=SR_SUM_TXT&no_of_clusters=100
    ---
    tags:
      - Clustering API
    parameters:
      - name: dataset
        in: formData
        type: file
        required: true
        description: The fully qualified path of the dataset without the extension.
      - name: col
        in: query
        type: string
        required: true
        description: The column name on which the clustering needs to be done
      - name: no_of_clusters
        in: query
        type: integer
        required: true
        description: The number of clusters
    """    
    global data      
    data = data.fillna('NULL')



output = StringIO.StringIO()
data.to_csv(output,index=False)

resp = Response(output.getvalue(), mimetype="text/csv")
resp.headers["Accept"] = "text/csv"
resp.headers['Access-Control-Allow-Origin'] = '*'
resp.headers["Content-Disposition"] = "attachment; filename=clusters.csv"
return resp

这将返回一个可下载的链接，我必须将该链接重命名为csv以使其工作。

问题：我不能对文件这样做。无论我如何做，一旦我下载和重命名，excel说文件是损坏的，这就是。

我试过pyexcel和熊猫出类拔萃的作家，但没有成功。请帮帮我！

Answer 1

尝试使用flasgger下载excel。您可以将响应类型更改为“应用程序/八位元流”来解析它。

你试过改变米制吗？

我认为excel的传统mimetype是application/vnd.ms-excel。
