python - 如何从 iOS 应用程序调用在 Python 的 ladon 框架中开发的 Web 服务？
<p><p>Web 服务基于 Python 的 <a href="http://ladonize.org/index.php/Main_About" rel="noreferrer noopener nofollow">Ladon</a>框架。</p>
<p>Web 服务 URL 为:<a href="http://ladonize.org/python-demos/Calculator" rel="noreferrer noopener nofollow">http://ladonize.org/python-demos/Calculator</a> </p>
<p>调用web服务的代码如下:</p>
<pre><code>NSString *requestString = [NSString stringWithFormat:
@"http://ladonize.org/python-demos/Calculator"];
NSString *jsonString = ;
NSData *jsonData = length: ];
NSURL *url = ;
NSMutableURLRequest *request = ;
;
;
;
;
] forHTTPHeaderField:@"Content-Length"];
NSError *errorReturned = nil;
NSURLResponse *theResponse =[init];
NSData *data = ;
if (errorReturned) {
NSLog(@"Error %@",errorReturned.description);
}
else
{
NSError *jsonParsingError = nil;
NSMutableArray *arrDoctorInfo= ;
NSString* newStr = ];
NSLog(@"Dict %@",newStr);
}
</code></pre>

<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>您使用的 URL 路径似乎错误，应更改为 <code>http://ladonize.org/python-demos/Calculator/jsonwsp</code>。</p>
<p>创建 <code>jsonData</code> 的更好方法是使用 <code>dataUsingEncoding:</code>。</p>
<p>您不应该创建响应:</p>
<pre><code>NSURLResponse *theResponse =[init];
</code></pre>
<p>因为它将作为 <code>sendSynchronousRequest</code> 的一部分创建并返回给您。您应该做的是检查 <code>theResponse</code> 的内容以验证 HTTP 状态代码。</p></p>
